Best Block Making Machines in Pakistan – Complete Industrial Buyer Guide by Silver Steel Mills
Pakistan’s construction sector has expanded aggressively over the last few years. Housing societies, commercial buildings, warehouses, industrial units, and infrastructure projects are increasing in almost every major city. Because of this, demand for concrete blocks, pavers, fly ash bricks, and tuff tiles has grown steadily across the country.
This demand has also increased searches for:
- best block making machine in Pakistan
- automatic block machine price
- concrete block factory setup
- fly ash brick machine
- paver block machine in Pakistan
- hydraulic block making machine
At Silver Steel Mills, we regularly work with factory owners, contractors, and construction companies who want reliable production systems rather than cheap short-term machinery. One thing most experienced buyers understand after entering this industry is that block manufacturing is not simply about buying a machine — it is about production stability, raw material control, maintenance planning, and long-term operational efficiency.
This guide explains how professional manufacturers evaluate block making machines in Pakistan and what buyers should actually focus on before investing.

The Definitive Guide to the Best Block Making Machines in Pakistan (2026 Edition)
The concrete masonry market in Pakistan has reached a critical turning point. Long gone are the days when traditional red clay bricks could sustain commercial building timelines. Driven by strict environmental regulations on coal-fired kilns, soaring labor wages, and the exact engineering standards demanded by projects like DHA, Bahria Town, and CPEC-linked infrastructure, concrete blocks have permanently claimed the market.
However, entering this industry or upgrading your existing plant requires more than just capital—it demands heavy-duty machinery capable of surviving the rigorous operational realities of Pakistan’s industrial landscape.
As mechanical fabricators with decades of floor experience at Silver Steel Mills, we have prepared this comprehensive, practical blueprint to help factory owners evaluate, source, and run the best block-making setups available today.
1. Market Demand & Future Trends in Pakistan
The current demand trajectory for concrete blocks (solid, hollow, and interlocking pavers) is exceptionally strong across Pakistan, particularly in Punjab and Sindh. Industrial warehouse development, multi-story commercial buildings, and housing society boundary walls are almost exclusively using concrete masonry units (CMUs).
Key Shifting Trends:
- The High-PSI Mandate: Civil engineers and lab inspectors at Tier-1 housing authorities no longer accept weak, hand-molded blocks. Contracts now specify minimum compressive strengths of 3,000 to 5,000 PSI, which can only be achieved via mechanized hydraulic compression and high-frequency vibration.
- The Transition to Automated Pavers (Tuff Tiles): Urban landscaping and motorway service plazas have generated a massive revenue stream for interlocking tuff tiles. The best block machines in 2026 are multi-functional plants that allow you to swap molds from a standard 8-inch block to an interlocking paver in under 45 minutes.
2. Machine Classifications & Technical Specifications
Selecting the right machine requires looking past shiny fresh paint and auditing the actual physical structure: the steel plate thickness, hydraulic valve origins, and the deadweight of the vibration table. Cheap, unbranded workshops cut corners on these hidden components, leading to frame fractures within six months.
At Silver Steel Mills, we classify heavy-duty machinery into three robust tiers designed specifically for regional operating conditions.
Comprehensive Technical Blueprint
| Technical Parameters | Heavy-Duty Manual Plant | Semi-Automatic Hydraulic (S-18 / S-24) | Fully Automatic PLC Plant (S-35 / S-50) |
| Main Frame Steel Thickness | 10mm to 12mm Solid Plate | 14mm to 16mm High-Tensile Plate | 18mm to 24mm Prime Cast Steel |
| Hydraulic Pressure Range | N/A (Mechanical Leverage) | 120 to 160 Bar | 180 to 220 Bar |
| Vibration System Type | Unsynchronized Eccentric | Dual-Shaft Synchronized Vibro | Quad-Directional High-Frequency |
| Molding Cycle Time | 45 – 60 Seconds | 22 – 30 Seconds | 15 – 18 Seconds |
| Control Interface | Manual Foot/Hand Levers | Mechanical Valve Levers | Siemens PLC Touchscreen with Automation |
| Weight of Machine Core | ~1.5 Tons | ~3.8 to 5.2 Tons | ~8.5 to 14 Tons |
3. Production Capacity Layouts
Your daily output determines your cash flow and your ability to fulfill large commercial orders on schedule. The table below outlines real-world production capacities over a standard 8-hour shift, accounting for realistic operational efficiency.
| Machine Model / Tier | 8-Inch Hollow Blocks (12×8×4 inches) | Standard Brick Equivalent | Interlocking Tuff Tiles (Uni / Double-Hex) |
| Manual Mechanical Plant | 800 – 1,200 Units | 4,000 Units | Not Recommended |
| S-18 Semi-Automatic | 2,200 – 2,800 Units | 10,000 Units | ~2,500 Units |
| S-24 Industrial Tier | 3,500 – 4,500 Units | 18,000 Units | ~4,000 Units |
| S-50 Mega Automatic PLC | 10,000 – 12,500 Units | 50,000 Units | ~12,000 Units (Double Layer Colored) |
4. Operational Infrastructure Requirements
Setting up a factory without calculating proper spatial layouts, raw material handling zones, and utility limits is a recipe for internal logistical bottlenecks.
Area Allocation (Space Matrix)
- Minimum Space Requirement: You need at least 3 to 4 Kanals for a semi-automatic installation. For a fully automatic line featuring a concrete batching plant and dedicated stacking yards, a minimum of 1 Acre (8 Kanals) is non-negotiable.
- Layout Design: The aggregate storage (sand and crush) must be situated directly behind the pan mixer. The green curing zone must lead sequentially to the stacking yard, allowing a smooth, one-way flow for forklifts or manual trolleys without backtracking.
[Raw Aggregates Zone] ➔ [Pan Mixer / Batching] ➔ [Block Core Machine] ➔ [Initial Green Curing Area] ➔ [Main Stacking & Water Sprinkling Yard]
Electricity & Backup Utility Limits
- Power Connection: Small manual setups can survive on a 3-Phase commercial connection of 15 kW. However, industrial semi-automatic and automatic lines demand a 3-Phase B2 Connection ranging from 35 kW to 90 kW.
- The Diesel Generator Rule: Grid load shedding can ruin a concrete mix mid-cycle. If a power failure occurs while cement is inside your pan mixer, the batch will harden and destroy the mixing arms. A backup 50 kVA to 150 kVA diesel generator (Perkins or Cummins core) is a mandatory safety net for high-production plants.
5. Raw Materials & Advanced Mix Designs
The mechanical compaction of a machine is only half the equation; your material quality determines the ultimate load-bearing capability of the block.
Material Sourcing in Pakistan:
- Coarse Aggregates (Crush): $1/4$-inch down fine crush, commonly referred to as Chinga or Bajri. Depending on your location, source from Margalla, Sargodha, or Hub quarries. It must be angular, not round river stones, to allow optimal bonding.
- Fine Aggregates (Sand): Clean river sand or Lawrencepur fine sand. High clay content will weaken the cement matrix; always run a silt test before purchasing dumpers.
- Cement: Ordinary Portland Cement (OPC) from reputable regional manufacturers (Maple Leaf, Lucky, Bestway).
- Fly Ash: A highly profitable addition when setting up automatic brick plants. Replacing 12% of your cement content with industrial fly ash maintains structural density while reducing aggregate raw costs.
Standard 3,000 PSI Structural Mix Ratio:
$$text{Mix Formula} = 1 text{ Part Cement} : 3 text{ Parts Sand} : 5 text{ Parts Coarse Aggregate}$$
The water-to-cement ratio must be strictly monitored. The concrete must be semi-dry. If it feels like mud, the block will cave in immediately when demolded. It should just hold its shape when squeezed in your palm.
6. The Production & Manufacturing Process
[Raw Batching] ➔ [Dry Aggregation Mixing] ➔ [Moisture Induction] ➔ [Hopper Distribution] ➔ [Vibro-Compression Cycle] ➔ [Demolding onto Pallets] ➔ [Hydration Curing]
- Precision Batching: Aggregates, sand, and cement are mechanically loaded into a heavy-duty pan mixer.
- Controlled Blending: The materials are dry-mixed for 120 seconds, followed by controlled water injection through spray nozzles until the semi-dry moisture threshold is hit.
- Mold Feeding: The concrete is dropped onto a rubber conveyor belt and transported into the machine’s primary storage hopper, which distributes the aggregate evenly into the mold cavities.
- Vibro-Compression: The top tamper head slams down under hydraulic pressure while the bottom vibration table activates at 4,500 rpm. Within 5 to 8 seconds, the intense kinetic energy forces out all micro-air pockets.
- Ejection & Demolding: The hydraulic ram lifts the mold upward, leaving the perfectly formed, solid concrete units resting neatly on a wooden or PVC pallet.
7. Workforce Management (Labor Allocation)
Even with automated PLC systems, your floor labor must function like a well-oiled gear. Mismanagement here results in broken green blocks and dropped production speed.
Staffing for a Semi-Automatic Industrial Line:
- Machine Foreman / Chief Operator (1): Manages hydraulic valve configurations, cycle timers, and tracks pump temperatures.
- Batching Mixer Loader (2): Loads the raw sand, crush, and cement bags into the pan mixer based on the strict engineering ratio.
- Green Block Lifters / Trolley Drivers (3): Carefully move the fresh, un-curing blocks away from the core frame onto the initial storage tracks.
- Stacking & Water Curing Labor (2): Stack the 24-hour-old hardened blocks and maintain continuous moisture delivery via water sprinklers.
8. Financial Analysis & Profit Potential
Let’s calculate an honest, practical cost breakdown based on active market rates for an 8-inch hollow concrete block ($12 times 8 times 4$ size).
- Raw Material Cost: Rs. 42 – Rs. 48 (Cement, Sand, Crush blend allocation)
- Labor Wages (Per Unit): Rs. 5 – Rs. 7
- Electricity, Diesel & Generator Wear: Rs. 4 – Rs. 6
- Pallet Wear & Water Costs: Rs. 1.5
- Total Production Cost: Rs. 52.5 – Rs. 62.5 Per Unit
Wholesale Market Pricing & Revenue:
The standard wholesale price for a certified 8-inch load-bearing hollow block ranges from Rs. 80 to Rs. 100, depending on local construction activity.
- Average Net Profit Per Unit: Rs. 20 – Rs. 30
- Daily Yield Statement: Producing a steady 4,000 blocks per shift yields a net daily profit potential of Rs. 80,000 to Rs. 120,000. For a well-managed yard, the entire initial investment pays for itself within 7 to 9 months of active operational deployment.
9. Mechanical Maintenance & Longevity Guidance
Concrete block manufacturing is brutal on iron components. Abrasive sand dust and moisture create a grinding paste that can score hydraulic rods and wipe out bearings if regular maintenance is skipped.
- The End-of-Shift Washdown Rule: Never allow concrete dust to settle on the machine at night. Wash down the mold boxes, guide pillars, and mixing blades every single evening. Hardened slurry buildup alters the tolerances of your machine and leads to uneven block heights.
- Hydraulic Fluid Management: Monitor your hydraulic oil (Grade 68). Change the initial fluid after 500 hours of run time to flush out manufacturing particles, then change it every 2,500 operational hours. Keep oil temperatures below 60°C to avoid ruining the internal valve seals.
- Grease Cycles: Lubricate main eccentric shafts, guide bushings, and motor couplings every morning before turning on the power.
10. Buyer Guidance: Avoiding Common Manufacturing Scams
When searching for block making machines on platforms like OLX or visiting unverified small roadside engineering shops, buyers frequently fall into expensive traps.
The Gadani Ship-Scrap Fraud
The single biggest scam in Pakistan’s machinery market involves the steel frame itself. Cheap local fabricators (such as KM Mughal and similar unauthorized workshops) purchase low-cost, rusted, re-rolled steel plates or decommissioned metal from ship-breaking yards. They weld these plates into machine frames, apply a thick layer of body filler (pootin), and spray it with shiny paint.
Under the extreme force of a 4,500 rpm vibration table, this brittle, re-rolled metal develops structural stress fractures within months. Always demand to inspect raw, unpainted steel plates on the fabricator’s shop floor.
[Scrap/Re-rolled Steel] ➔ [Vibration Stress] ➔ [Micro-fractures within 6 months] ➔ [Total Machine Failure]
[Prime New Steel Plate] ➔ [Uniform Elasticity] ➔ [Absorbs 4500 RPM Cycles] ➔ [15+ Years Service Life]
Refurbished “Kabli” Hydraulics
To cut costs, low-tier workshops fit machines with refurbished, second-hand hydraulic pumps, directional control valves, and motors sourced from junk markets. These components cannot hold uniform pressure once the hydraulic oil heats up, leading to irregular block densities. At Silver Steel Mills, we use exclusively brand-new, high-pressure industrial hydraulic systems to guarantee absolute operational reliability.
11. Frequently Asked Questions (FAQs)
Q1: Can I make blocks and tuff tiles on the same machine?
Yes. By unbolting the standard hollow block mold and dropping in an interlocking paver mold, you can produce tuff tiles, solid blocks, or kerbstones on any Silver Steel Mills semi-automatic or automatic model.
Q2: Why are the blocks from my local manual machine cracking at the edges?
This is caused by either insufficient hydraulic down-pressure, low vibration frequency, or a dry aggregate mix. If the concrete isn’t properly consolidated during the compression cycle, the edges remain soft and break during demolding or transport.
Q3: How long should concrete blocks be cured before delivery to a site?
Blocks must remain in the initial curing bay for 24 hours. After that, they must be stacked and watered under a sprinkler line for a minimum of 7 to 10 days. Delivering blocks before this period is risky and will fail lab crush tests.
Q4: Is a wooden pallet better than a PVC pallet?
Seasoned wooden pallets are cost-effective for starting out. However, due to continuous water exposure, they eventually warp. High-density PVC or composite pallets last significantly longer and maintain a perfectly level base for your blocks.

Best Block Making Machines in Pakistan: A Practical Guide for Smart Investors (2026 Edition)
If you have spent even a week in the construction industry in Lahore, Karachi, or Peshawar, you know the bottleneck isn’t cement—it’s the consistency of the blocks.
At Silver Steel Mills, we have supplied the raw steel for fabrication and watched the machinery market evolve for over two decades. We have seen cheap Chinese knock-offs rust in six months, and we have seen German-engineered machines that cost more than a house in DHA.
This guide is not a Wikipedia summary. It is a boots-on-the-ground breakdown of exactly what you need to know before putting your PKR 25 to 50 lakhs on the line. We are looking at vibration systems, hydraulic pressure, power bills, and real ROI in the current economic climate of Pakistan.
H2: Understanding the Pakistani Block Machine Landscape
The “best” machine depends entirely on where your site is located. Are you in a rural area with cheap labor and frequent load-shedding? Or are you supplying high-rise projects in Gulberg where missing a delivery deadline means losing a contract?
Broadly, the market in Pakistan splits into three tiers:
- Manual / Semi-Automatic (Egg-Layers): Best for startups. Low electricity, high labor.
- Hydraulic / Stationary Presses (QT series): The industry standard in Pakistan. High density, commercial use.
- Fully Automatic Plants: For industrial zones and high-volume production (10,000+ blocks/day).
We will focus primarily on the Semi-Automatic and Stationary Hydraulic models (like QT4-18, QT5-20, and local Pakistani fabrications), as they offer the best balance of affordability and output for the local investor .
H2: Detailed Machine Specifications (What The Brochure Won’t Tell You)
When a dealer hands you a spec sheet, they show you “Vibration Force: 70KN.” You need to ask them: Is that table vibration or mold vibration?
For Pakistani aggregate (which often contains hard sargodha crush), table vibration is superior. It settles the concrete more evenly.
Here is a realistic spec comparison for the two most popular machine sizes in Pakistan:
| Feature | Small Scale (QT4-15 / 4-18) | Commercial Scale (QT5-20 / 6-15) |
|---|---|---|
| Pallet Size | 850×550 mm | 1150×580 mm |
| Vibration Type | Hydraulic + Table | Servo / Hydraulic (Dual) |
| Control System | PLC + Touch Screen (Semi-Auto) | PLC + Touch Screen (Auto) |
| Cycle Time | 15-20 Seconds | 14-18 Seconds |
| Installed Power | ~28-32 kW | ~38-45 kW |
H3: The Steel Quality Matters
Being from Silver Steel Mills, we must stress this: Check the alloy of the mold. Local “Desi” molds use mild steel and wear out after 10,000 blocks. High-carbon molds imported or made from high-grade scrap last for 100,000+ blocks. If the price looks too good, check the hardness of the mold plates.
H2: Production Capacity (Real Numbers vs. Theoretical Numbers)
A dealer will tell you a machine produces “10,000 blocks per day.” That is usually based on a 10-hour shift using hollow blocks (which are larger and take fewer cycles to fill a pallet).
Realistic Production in Pakistan (8-hour shift, accounting for prayer breaks and material loading):
- Solid Blocks (Standard 4″): 2,500 – 3,500 pcs/shift.
- Hollow Blocks (6″): 4,000 – 6,000 pcs/shift.
- Interlocking Pavers: 300 – 500 sq. ft./shift.
Pro Tip: Do not run the machine at 100% speed all day. The hydraulic oil will overheat (especially in summer in Multan or Sialkot). Run at 80% capacity to save on repair bills.
H2: Electricity & Power Requirements
With the current circular debt and electricity costs in Pakistan (approx PKR 35-45 per unit for industrial), power is your biggest overhead.
- Small Machines (Manual/Semi): Require 10-15 kW. They can often run on a 20HP electric motor or even a diesel engine (a huge advantage for rural Sindh/KPK where power is unstable).
- Medium Hydraulic (28-32 kW): You need a 60-80 kVA generator as backup. Do not skip the generator. A voltage fluctuation will fry the PLC (Programmable Logic Controller) card, which costs PKR 50,000+ to replace.
- Energy Saving: Look for machines with Servo Motors. They cost 20-30% more upfront but cut your electricity bill by 40% because the motor only works when pressure is needed, not all the time.
H2: Labor Requirements (How Many Men Do You Need?)
This is where automation pays for itself in 12 months.
- Manual Machine: 6-8 workers.
- 2 Mixer operators, 4 Molding/Compression, 2 Offloading.
- Semi-Automatic (QT4 type): 4-5 workers.
- 1 Mixer/Control, 2 Block handling, 1 Pallet return, 1 Forklift.
- Automatic: 2-3 workers (mostly for maintenance and forklift driving).
The Reality: Daily wage labor in Pakistan has jumped 25% in the last two years. A semi-automatic machine saves you PKR 60,000+ per month in wages compared to a manual machine.
H2: Factory Area & Layout (Don’t Buy a Machine You Can’t Fit)
We have seen investors buy a machine only to realize their 1 Kanal plot is too small for the curing yard.
Minimum Area Requirements:
- Production Shed: 100 sq m (Covered. Do not put a hydraulic machine in the sun—the oil will degrade).
- Curing Area: 500 sq m (This is the killer. You need space to stack blocks for 7-14 days).
- Raw Material Stock: 200 sq m (Sand, crush, and cement storage must be dry).
- Aggregate Batching (if separate): 50-80 sq m.
Total Required: Approx 800 sq m (8 Marla) to start. For a fully automatic setup with a yard, aim for 2+ Kanal .
H2: Raw Materials (Sourcing in Pakistan)
The “Block Making Machine” is just a press. The quality comes from the mix design.
- Cement: Bestway, Lucky, or DG. Use Grade 42.5 or above. Do not use expired or lumpy cement.
- Crush / Bajri: Use 1/4″ to 1/2″ (4mm to 12mm). Too much dust ruins the block color.
- Sand: Washed sand only. Sea sand or salty sand will cause efflorescence (white stains) and rust your steel reinforcement inside the block.
- Water: Clean. The same water you would drink. Dirty water reduces strength by 30%.
- Admixture (Optional): In winter, you might need accelerators; in summer, retarders. A small bottle costs PKR 5,000 but saves thousands of rupees in cracked blocks.
H2: The Manufacturing Process (Step-by-Step)
If you are new, here is the workflow you will follow daily:
- Batching: Measuring cement, sand, and crush. (Manual weighing is inaccurate; use a batching scale or a weigh batcher if you can afford it).
- Mixing: Loading into a planetary or drum mixer. Minimum mixing time: 3 minutes.
- Molding: The aggregate drops into the mold. The machine vibrates and presses.
- Curing: This is where most Pakistani block makers fail. Blocks need water for 7 days. Steam curing is ideal but costly. Water curing requires a dedicated worker with a hose 3 times a day.
- Stacking: After 24 hours, the blocks can be moved. After 7 days, they can be sold (full strength at 28 days).
H2: Business Profit Potential (The Math)
Let’s use current market rates (PKR) for a medium-sized operation producing 4,000 Hollow Blocks (6 inches) per day.
| Parameter | Calculation |
|---|---|
| Selling Price (Local Market) | PKR 95 – 110 per block |
| Raw Material Cost (Cement, Sand, Crush) | ~PKR 55 per block |
| Labor & Electricity | ~PKR 10 per block |
| Maintenance & Wear/Tear | ~PKR 5 per block |
| Profit Per Block | PKR 25 – 40 |
Daily Profit (conservative): 4,000 x 25 = PKR 100,000/day.
Monthly Profit (26 working days): PKR 26 Lakhs.
Note: This ignores the “wastage factor” (5-10% breakage during curing) and marketing costs. It is a good business, but it is not “get rich overnight.” It is a volume game.
H2: Maintenance Guidance (Extending Machine Life)
The humidity in Karachi and the dust in Punjab are your machine’s enemies.
- Hydraulic Oil: Change it every 1,000 hours. In Pakistan, use Shell Tellus or Mobil DTE. Cheap oil is the #1 reason for pump failure.
- Greasing: The bushes and pins need grease every 8 hours. Use a manual grease gun; automatic lubrication systems are great but rare in local setups.
- Mold Care: At the end of each day, brush the mold with a wire brush and spray diesel or oil on it. Concrete sets like rock. If you leave it overnight, you will need a chisel to clean it.
- Bolts: Vibration machines shake themselves apart. Check the foundation bolts weekly .
H2: Comparison Tables (Models & Suppliers)
Since you are reading this on Silver Steel Mills, we are neutral. We don’t sell machines; we sell the steel to build them. Here is how the current market stacks up:
| Supplier Origin | Price Range (PKR) | Pros | Cons |
|---|---|---|---|
| Local Fabrication (Pakistan) | 8 – 15 Lakhs | Cheap parts, easy repair, no import hassle. | Lower density blocks, rough finish, high wear rate. |
| Turkish / Iranian | 25 – 40 Lakhs | Good density, good hydraulics. | Parts availability in Lahore is slow (4-6 weeks). |
| Chinese (Standard) | 18 – 30 Lakhs | Best value for money, PLC technology. | Electrical components (sensors) are fragile; keep spares . |
| European | 1 Crore + | 20-year lifespan, perfect blocks. | Too expensive for 99% of Pakistani SMEs. |
H2: Market Demand in Pakistan (Where to Sell?)
Don’t make blocks and hope to sell. Get buyers first.
- High Demand Zones: DHA (Karachi/Lahore), Bahria Town, CPEC housing projects, and the “Naya Pakistan” housing scheme.
- Product to focus on: Interlocking Pavers. Margins on grey blocks are tight. Colored pavers for driveways have a 40-50% profit margin.
- Timing: Demand peaks from October to March (winter/dry season). Production drops in Monsoon (July-Aug) because you cannot cure blocks properly in the rain.
H2: Future Industry Trends (2026 and Beyond)
The era of the simple “vibropress” is ending. Here is what is coming:
- AAC Blocks (Autoclaved Aerated Concrete): Lightweight blocks are eating the high-rise market. You cannot make them with a standard machine; they require autoclaves.
- Fly Ash Utilization: With coal plants in Sahiwal and Port Qasim, Fly Ash is cheap. Machines that can handle fly ash mix will save money.
- Digital Batching: Buyers now test block strength with digital rebound hammers. You need a computerized weigh batcher to maintain consistency.
H2: Buyer Guidance (Final Checklist)
Before you hand over the cash, do this:
- Visit a running factory using the same model. Don’t just watch a video.
- Check the Pallet Thickness. 20mm pallets bend. 25mm+ steel pallets are mandatory for true blocks.
- Negotiate the Spares Kit. Ensure they include at least 1 full set of sensors, 2 belts, and a set of bushes.
- Ask about Installation. Does the price include leveling and commissioning? Many Chinese suppliers leave you hanging.
H2: Frequently Asked Questions (FAQs)
Q: Can I make solid and hollow blocks on the same machine?
A: Yes, if you change the mold. A standard QT4 or QT5 machine uses interchangeable molds. Molds cost roughly PKR 150k to 300k per shape.
Q: What is the best generator size for a 30kw machine?
A: You need a 75-100 kVA generator. The starting load (inrush current) is 3x the running load.
Q: Is the block making business profitable in Pakistan in 2026?
A: Yes, but only if you control your logistics. The profit is in selling, not making. A lot of factories shut down because they made blocks but couldn’t deliver them cheaply.
Q: Silver Steel Mills sells machinery?
A: We don’t sell the machines. We supply the high-grade steel and fabrication materials used to build the frames of these heavy machines. When you buy a local block maker, ask them if they use Silver Steel Mills raw material for the frame. It matters for vibration resistance.
