DX53D Formable Galvanized Steel Coil For Automotive
Product Description
Our DX53D Formable Galvanized Steel Coil is engineered for high-performance automotive applications, combining superior deep-drawing capabilities with exceptional corrosion resistance. The hot-dip galvanized coating (Zinc Coating: 60-275g/m²) provides robust sacrificial protection, ensuring longevity in harsh environments. With a tensile strength of 270-380 MPa and elongation exceeding 30%, this coil is ideal for complex forming processes like deep drawing and stamping without cracking or coating peeling. Certified to ASTM A653, EN 10346, and JIS G3302 standards, it meets stringent automotive industry requirements for durability, weldability, and paint adhesion. The surface finish (zero spangle or minimized spangle) ensures a smooth base for painting and coating.
