Hot Rolled Steel

Hot Rolled Steel(Hot Rolled Steel)

Hot rolled products consist of hot rolled coils produced by hot strip mills and hot rolled coils cut out of them. Some of the hot-rolled coils produced at the hot rolling mill are sold as finished products or used as intermediate materials for cold rolling and electric steel sheets. It is reworked with high value-added products. And It has high strength and excellent weldability, processability, corrosion resistance, so it is widely used in various industries.
