Cold-rolled steel sheets are thin steel sheets made from hot-rolled steel coils through pickling and rolling processes at room temperature. They are widely used in automobiles, home appliances, construction and other fields.

SGCC, SECC, and SGLD are all types of galvanized sheets, which have anti-rust and corrosion-resistant properties and are widely used in many fields.

Pickled plate is a hot-rolled plate that has been subjected to processes such as dephosphorization (removing rust, residues, etc. generated during hot rolling) and pickled on the surface to obtain a steel plate with better surface performance than hot-rolled plate.

Tinplate coil is a process of thinly coating tin (Sn) on steel coils or steel strips. Tinplate is a lightweight, cold-rolled low-carbon steel plate or strip coated on both sides with industrial pure tin.

TFS is a cold-rolled steel characterized by its thin gauges between 0,13 – 0,50 mm.

GI corrugated sheet is a cold-rolled continuous hot-dip galvanized steel sheet and strip with a thickness of 0.25~2.5mm.

Hot-dip galvanized square pipe is a square pipe made of steel plate or steel strip after crimping and welding, which is formed by a series of chemical reactions in hot-dip galvanized pool.

The cold rolling process is a manufacturing process used to work sheet metal, usually carried out at room temperature.

Cold rolling refers to processing steel plates or steel strips into various types of steel through cold drawing, cold bending, cold drawing and other cold processing at normal temperature.
