SPHC is manufactured through a process known as hot rolling, where steel is passed through rollers at high temperatures to form sheets or strips. This helps improve its physical properties such as strength, durability, and ductility.

A572 is a low-carbon, low-alloy high-strength steel coil produced employing the electric furnace steelmaking technology. So the main component is scrap iron. Owing to its reasonable composition design and strict process control, A572 steel coil is widely favored for high purity and excellent performance.
