Production Capabilities


ISL's 500,000 tons per annum steel complex produces Cold Rolled, Galvanized and Color Coated Steel from hot rolled coils. ISL's current production mix comprises of 100,000 tons of Cold-Rolled Product, 350,000 tons of Hot-Dip Galvanized and 50,000 MT of Color Coated Steel, which are offered in coil or sheet form. All products cater to the engineering and manufacturing industry as a premium raw material for transformation into any number of value-added products for the domestic and export markets.

Cold Rolled Steel is available in thicknesses ranging from 0.25 mm to 3.0mm, galvanized steel is available in thicknesses of 0.25 mm to 2.0mm while color coated steel is available in thickness range of 0.20 -1.50 mm. All products are offered in a maximum width of 1,250mm and each product category is provided in a range of strength levels from drawing to structural and surface finishes from bright to matt to meet our customer specific requirements.

ISL produces are offered in a maximum width of 1,225mm and each product category is provided in a range of thickness, strength levels and finishes depending on customers end application.

Cold Rolled Steel is available in thickness ranging from 0.25mm – 3.00mm in various strength grades for general fabrication, drawing applications, structural applications and surface finishes from bright to matt to meet specific customer requirements. Matt finish is preferred for subsequent lacquer or paint finishing where parts undergo a drawing operation. Bright surface is preferred for subsequent electroplating operations.

Galvanized Steel is offered in thickness ranging from 0.25mm – 2.00mm in the traditional regular spangle and bright finish. Galvanized product can also be offered with minimized spangle and skin passed which is generally preferred where paint applications are required. Color Coated Steel is available in thickness range of 0.20mm to 1.50mm Polyester (PE), PVDF and Polyamide Paint and on various substrates such as Galvanised, Galvalume, Aluminium and Stainless Steel.

The diversity of products in terms of strength levels, steel chemistry, and metal coating provide high quality inputs for the various applications and products.

Effluent Treatment Plant

ISL has set up a state of the art Effluent Treatment Plant. This plant will ensure collection, neutralization and filtration of the entire solvent based wastages generated during the process and will make them re-usable. The used hydrochloric acid from the strip pickling line is re-generated so that 98% is re-used and only 2% neutralized is discharged. ISL reverse osmosis generates over 100m3/hr of water to meet industrial requirements and does not rely on Karachi’s over loaded water system.

The investment has helped ISL:

  • Reduce water usage for industrial purposes.
  • Reduce industrial waste.
  • Improve water availability for local residents by re using industrial water.

Power Plant

An 19.2 MW gas fired Co-generation power plant which is meeting the needs of ISL steel complex and supplying electricity to the Grid.
