Premium high strength zinc coated steel coil with modified alloy formulation. Delivers excellent tensile properties, severe bendability, and superior atmospheric corrosion resistance.
Authentic Steel engineers high strength zinc coated steel coil using advanced alloy formulation designed for demanding structural and metal forming applications. Combining structural steel substrates with high-performance zinc-based alloy coatings containing aluminum and magnesium, this product meets the highest demands for mechanical strength, press formability, and long-term anti-rust endurance in aggressive commercial environments.
Structural fabricators require steel that delivers high yield strength without compromising bending ductility or coating adhesion. Our high strength zinc coated steel coil prevents coating flaking, peeling, or micro-cracking even during deep drawing, roll forming, and 180-degree severe bending. The specialized alloy coating provides dual-layer protection: a physical barrier against moisture and aggressive chemical agents, and dynamic galvanic cathodic protection along all cut edges and punched holes.
