The Coated steel is a treated form of steel covered with a specialized coating to improve durability and resistance to rust or chemical reactions. Steel is naturally strong but can oxidize when exposed to water and air, which leads to corrosion and weakens the structure. The protective layer applied in coated steel keeps oxygen and moisture from reaching the surface, preventing rust and increasing lifespan. Coatings may include metallic layers or polymer-based coatings depending on industrial needs. The finish also helps improve the overall appearance, mechanical strength, and wear resistance, making it highly suitable for manufacturing purposes.

Its applications extend to industries such as automotive manufacturing, building construction, and industrial equipment production. Coated steel is used in pipelines that transport gas or liquids, steel roofing sheets, storage tanks, metal-reinforced frames, HVAC ductwork modules, door enclosures, machinery casings, warehouse frames, shipping and storage containers, heavy equipment parts, guard rails along highways, industrial surface sheet frames, agricultural steel bases, marine-tolerant inserts, electrical insulation frames, power distribution enclosures, and conveyor mechanical hardware modules. It also supports bending, stamping, drilling, and welding processes without coating cracks. With strong resistance and easy processing, coated steel is important for industrial engineering.
