Our Process

Scrap

As a leading steel supplier in Karachi, we source high-quality scrap materials, including HMS 1, HMS 1&2, and ISRI grades, from trusted regions worldwide, primarily Europe. Our facility is equipped with heavy-duty cranes for efficient handling and industrial magnets that transfer the scrap into the induction furnace for melting.

Electric Induction Furnace

Industrial buckets are used to carefully load scrap into our electric induction furnace, where it is melted and refined into prime billets. In order to make sure that every billet satisfies stringent international standards, our team constantly checks the chemical composition during this stage, which includes carbon, manganese, phosphorus, sulfur, and silicon.

CCM

The Continuous Casting Machine (CCM), which receives the molten metal from the furnace, carefully transforms it into uniform billets that are prepared for the following phase of production.

Billets

The primary raw material used to make high-strength steel rebars is these hot-rolled billets. They are perfect for direct rolling in our mill because of their consistency and structural soundness.

Rolling Mill

The billets are transported via automatic conveyors to our state-of-the-art rolling mill, where they are shaped into steel rebars under controlled temperature and speed for consistent quality.

Cooling Bed

Freshly rolled steel rebars are transferred to our 120-foot cooling bed. Here, they are evenly cooled and accurately cut to the desired length, either per foot or as per customer specifications, before bundling.

Dispatch

Before dispatch, every steel rebar bundle is weighed and inspected. Random quality tests are conducted in our in-house laboratory to ensure full compliance with international standards. Any rejected pieces are promptly separated. Finally, each approved bundle is labeled with our official tag, marking it ready for safe and timely delivery.
