The Flat Products Complex
The flat products complex of Rahim Steel Mills Co. (Pvt.) Ltd. comprises of Slab Casting Unit & Hot Rolling Plate Mill with all modern facilities & sophisticated computerized process control system.
Quality at Every Stage
Quality control at every stage, from raw materials selection, steel making, slab casting to final hot rolling and grading of rolled products are ensured by a team of experts. In addition to a large group of skilled workers & technicians, we have a number of Metallurgist, Chemists & Engineers of different discipline in our organization.
Quality Control Department is Equipped: Laboratory with all modern equipment & chemicals
Analysis of Organic & Inorganic elements & their compounds such as Steel, Ray Hard Coke, Ferro Alloys etc. We have country's first spectrometer of ARL Switzerland mark for instant analysis of 22 elements in steel. This analysis facilities help to ensure the quality of raw & subsidiary raw material along with finished products.
Spectrometer for instant analysis of 22 elements in steel.
Microscope with photographic attachment's & ultra-sonogram
AMicroscope is used for the microscopic analysis of steel such as grain size, inclusions etc. While the ultra-sonogram is used for non-destructive testing of steel plates.
100 M.T. & 60 M.T. universal testing machine & impact testing machine.
Elaborate physical testing of finished products for yield stress, ultimate tensile strength, plastic properties & resistance to impact to complement the chemistry efforts.
