How Are Steel Sheets, Plates, and Coils Manufactured?

Our coils, plates, and steel sheets play a vital role in the automotive, engineering, and construction sectors where strength, precision, and durability are important. Knowing about the manufacturing process of steel sheets helps industries choose the right material for their intended use.

Raw Material Preparation

The procedure starts with steelmaking, where raw iron is purified and alloyed to improve mechanical characteristics. This molten steel is cast into slabs using slab casting for further treatment.

Hot Rolling Steel Process

In hot rolling, slabs are heated to high temperatures and rolled through rollers to attain the required thickness. The metal is subsequently cooled in a controlled process to improve its structural strength.

Cold Rolling Steel

For thinner applications, the steel coil rolling method goes through cold rolling, enhancing mechanical strength, and surface finish. This steel hardening process improves the grain structures through recrystallization.

Finishing and Quality Control

Steel is inspected for dimensional tolerances, surface imperfections, and coating applications.
