Grade: Extra Deep Drawing Quality (DX52D / DX53D / DX54D)
Formability: High elongation for complex hydraulic pressing without necking or cracking.
Surface: Skin-passed Grade B (FB) extra smooth surface, free of stretch strain marks.
Factory Direct: Direct mill supply with customized coil weights (3.0 - 8.0 MT) to match your presses.
Designed for complex stamping, deep hydraulic drawing, and multi-stage metal forming, our Deep-Drawing Galvanized Steel Coil offers unmatched ductility and plastic strain capability. Utilizing vacuum-degassed ultra-low carbon steel chemistry, this coil exhibits a fine, uniform grain structure that prevents localized necking, orange-peel effects, or brittle tearing during deep press operations.
Drawing upon 30 years of specialized steelmaking mastery and 20 years supplying international auto-component and appliance makers, our mill applies a tight zinc-iron alloy control mechanism. The zinc coating adheres tenaciously to the base steel, guaranteeing zero zinc flaking or peeling even under extreme mechanical deformation and tight-radius stamping.
