The Coated steel is a specially treated metal where a protective layer is added on top of the steel surface to improve durability and resistance. This coating may include zinc, paint, resin, aluminum, magnesium blends, or polymer-based layers depending on the intended use. The main purpose is to shield steel from corrosion, moisture, chemicals, wear, and harsh environmental conditions. Bare steel can easily react with oxygen and water, leading to rust, which weakens the metal over time. Coating acts as a strong barrier, preventing these reactions and keeping the steel’s structural integrity intact. The coated surface also improves heat resistance, surface hardness, and appearance, which makes it valuable for both industrial and consumer use.

Coated steel is widely used in building structures, roofing sheets, home appliances, automotive body panels, storage tanks, pipelines, marine applications, agricultural equipment, fencing, outdoor frames, and electrical enclosures. It also supports forming, bending, machining, and stamping without cracking the surface layer, which is important for manufacturing. Different coatings add extra properties like UV protection, scratch resistance, and chemical tolerance. With improved strength, longer lifespan, reduced maintenance needs, and customizable surface finishes, coated steel continues to replace traditional unprotected metal in many areas where performance, look, and reliability are high priorities.
