Galvanized sheet is ordinary steel sheet coated with a layer of zinc to prevent rust, with the core being "steel sheet + zinc layer"; stainless steel contains chromium (≥10.5%) and other alloy elements, forming a passive film to prevent rust by itself, essentially being "alloy steel."

Stainless steel color-coated panels, as the name suggests, are made with stainless steel as the base material, then undergo a series of chemical treatments and organic coating applications to become a particularly durable new type of building material. Its wide application in the construction field is mainly due to its durability, heat resistance, and aesthetic appeal.

Cold-rolled thin plates are low-carbon steel plates processed through cold rolling, featuring good mechanical properties and surface quality, widely used in many industrial fields.
