HZS25 Concrete Batching Plant Delivered to Prime Construction Pvt Ltd, Islamabad
Powering Islamabad’s Development – A Compact Batching Plant for Prime Construction
In the construction industry, time is money. And when you’re building multi‑story apartments, commercial plazas, or infrastructure projects in a fast‑paced city like Islamabad, you cannot afford to wait for ready‑mix concrete trucks that get stuck in traffic or arrive with inconsistent slump.
Prime Construction Pvt Ltd – a respected name in the capital’s building sector – understood this well. They had several projects lined up in and around the federal capital, including housing schemes, office buildings, and road works. They needed a reliable, on‑site source of high‑quality concrete that they could control themselves.
In 2022, they approached Silver Steel Mills for a solution. After assessing their needs – daily volume, space constraints, and quality requirements – we recommended the HZS25 fully automatic concrete batching plant. This compact yet powerful station produces 25 cubic metres of concrete per hour, perfect for medium‑scale projects where consistency and speed are critical.
The plant was delivered, installed, and commissioned at Prime Construction’s Islamabad site. It has since become an indispensable asset, saving them millions in transport costs and ensuring every pour meets the highest standards.
The Challenge – Islamabad’s Traffic and Quality Demands
Prime Construction was facing two major problems:
-
Logistics nightmare – Ready‑mix trucks from distant batching plants often got stuck in Islamabad’s notorious traffic, arriving late or with concrete already starting to set.
-
Quality inconsistency – Even when the concrete arrived on time, slump and strength varied from truck to truck, leading to rejected pours and wasted material.
They needed a dedicated batching plant that could be set up right at their project site – small enough to fit in a congested urban area, yet powerful enough to supply all their concrete needs.
After evaluating several options, they chose Silver Steel Mills for our turnkey approach, local manufacturing, and proven track record with CPEC and defence projects.
The Solution – HZS25 Compact Batching Station
We designed, delivered, and installed a HZS25 concrete mixing station – a fully automatic, space‑saving plant that packs industrial capability into a small footprint.

The plant was designed for rapid installation and easy operation. Silver Steel Mills provided 15 days of on‑site guidance – from foundation preparation to full commissioning.
Production Reality – 25 m³ of Concrete Every Hour
After installation, the HZS25 plant consistently delivered:
| Parameter | Value |
|---|---|
| Hourly output | 25 m³ |
| Daily output (single shift, 8 hours) | 200 m³ |
| Monthly output (25 days) | 5,000 m³ |
This volume was more than enough to supply Prime Construction’s concurrent projects, including:
-
Apartment foundations – 500 m³ of high‑strength concrete.
-
Commercial plaza columns and beams – 300 m³.
-
Road paving – 200 m³ per week.
-
Boundary walls and drainage structures – various small pours.
“The HZS25 plant has been a game changer for us. We no longer rely on ready‑mix trucks that show up late. Now we make our own concrete, exactly when we need it. The JS500 mixer gives us a perfect mix every time, and the computerised control system ensures every batch meets our spec. Silver Steel Mills handled everything – delivery, installation, training. Highly recommended.”

Why the HZS25 Was Ideal for Prime Construction
1. Compact Footprint – Perfect for Urban Sites
The HZS25 takes up minimal space – the mixer, batching machine, and 100‑ton silo fit neatly into a corner of Prime Construction’s yard. In crowded Islamabad, where every square foot matters, this was a major advantage.
2. Fully Automatic – Consistent Quality, Minimal Labour
The computer‑based 4‑scale system automatically weighs cement, sand, crush, water, and admixture. The operator simply selects the recipe and presses start. The printer records every batch for quality assurance.
3. Fast Installation – 15 Days to Production
Our team completed the foundation, erected the plant, and commissioned it within 15 days. Prime Construction was pouring their own concrete less than three weeks after the plant arrived.
4. Easy to Maintain – Reliable Operation
The JS500 mixer’s high‑wear‑resistant alloy casing and blades lasted through the first year without replacement. The pneumatic system (air compressor) and hydraulic opening system have required only routine maintenance.
5. Cost‑Effective – Instant Savings
By producing concrete on site, Prime Construction eliminated:
-
Ready‑mix transport costs (approx. Rs 2,000 per truck).
-
Waiting time (no delays due to traffic).
-
Quality rejection (every batch is consistent).
Estimated annual saving : Over Rs 1.5 crore.
Financial Impact – A Smart Investment
| Parameter | Value |
|---|---|
| Plant cost (negotiated) | Rs 1 crore 55 lakh (approx) |
| Installation & training | Included (15 days guidance) |
| Daily output (average) | 200 m³ |
| In‑house cost per m³ | ~Rs 8,000 – 9,000 |
| Market ready‑mix cost per m³ | ~Rs 12,000 – 15,000 |
| Daily saving | Rs 8 – 12 lakh |
| ROI | 3‑4 months |
Prime Construction recovered the entire plant investment before completing their first major project.
The Human Side – Training Local Operators
Silver Steel Mills didn’t just deliver the plant; we trained Prime Construction’s team. Two operators received hands‑on training for 10 days – covering:
-
Recipe setting on the computer.
-
Daily startup and shutdown procedures.
-
Troubleshooting common issues (e.g., jammed aggregate gates, belt misalignment).
-
Preventive maintenance (greasing, blade inspection, calibrating load cells).
After our team left, Prime Construction’s operators ran the plant independently.
