Formulated for severe press braking and deep drawing operations, our drawing quality aluzinc steel strip features exceptional elongation and low yield ratios. Precision slitted down to narrow widths, it is the ideal raw material for HVAC ducting, stamped hardware, and cable trays without micro-cracking the coating.
Representing the advanced metallurgical processing capabilities of Winroad Group, Authentic Steel manufactures high-ductility drawing quality aluzinc steel strips optimized for deep drawing, continuous stamping, and HVAC ventilation duct roll-forming. Rooted near Tianjin Port with manufacturing experience dating back to 1994 and a global commercial footprint serving 78 countries, our precision slitting and annealing units utilize controlled anaerobic heat treatment to achieve high elongation ratings and low yield ratios. This metallurgical optimization enables press shops to stamp intricate geometry parts without micro-cracking the protective 55% aluminum-zinc alloy coating or creating edge burrs.
HVAC spiral ducting, stamped automotive brackets, and pressed hardware items require raw materials that survive severe bending and tight lock-forming without coating detachment. Our drawing quality (DQ / DDQ) aluzinc strips guarantee smooth seam tightness and clean edge retention, drastically extending tooling lifespan and reducing press shop downtime during continuous high-speed production runs. Precision slitting ensures exact width tolerances for seamless feeding into automated coil lines.
