Durable Zinc Aluminum Magnesium Coated Steel Coil for Cars
Durable Zinc Aluminum Magnesium Coated Steel Coil for Cars
Feature
-
The Zinc Aluminum Magnesium Coated Steel supplied by Zhanzhi Group is a premium hot-dip Zn-Al-Mg alloy coated sheet engineered for automotive manufacturing. Zinc-Aluminum-Magnesium Alloy Coated Steel delivers corrosion resistance 10 to 20 times greater than conventional hot-dip galvanized sheet and supports high-speed press forming, while each ZM Steel Coil ships with full mill traceability for body panels, structural reinforcements, and underbody components.
To meet varied engineering specifications, ZM Steel Coil is offered in two well-defined coating compositions: a 3% Mg / 11% Al formulation for the toughest corrosion environments, and a 1% Mg / 1% Al formulation for balanced formability and protection. Material is supplied in thicknesses from 0.3 mm to 2.5 mm, widths from 600 mm to 1250 mm, and custom lengths, wound to coil IDs of 508 mm or 610 mm at 3 to 5 tons per coil and packed in standard sea-worthy export packaging for long-distance shipment.

● High corrosion resistance: Zinc-Aluminum-Magnesium Alloy Coated Steel offers 10 to 20 times better corrosion resistance than hot-dip zinc-coated sheets, and 5 to 8 times better than hot-dip zinc-5% aluminum alloy coated sheets, as estimated by salt-spray testing.
● Cut-edge protection: A fine zinc-based protective film containing Al and Mg leached from the coating forms on the cut edges of ZM Steel Coil, sealing exposed steel against rust creep.
● Superior press formability: The harder, smoother coating of Zn Al Mg Steel supports consistent press performance, contributing to higher stamping productivity and fewer part rejections.
● Process and cost savings: Specifying zinc-aluminum-magnesium alloy coated sheet allows fabricators to eliminate the post hot-dip galvanizing step, reducing both initial tooling cost and total lifecycle cost.
● Flexible coil supply: Coils are produced to mill-spec tolerances and wound to standard 508 / 610 mm IDs, ready for slitting, cut-to-length, and downstream automotive lines.
● Wide engineering range: Available grades such as DC51D-DC57D+ZM and S250GD-S350GD+ZM cover structural, deep-drawing, and high-strength application needs.
● Automotive body panels, floor pans, reinforcements, and structural components
● Architectural building panels, perforated panels, and metal facades for construction projects
● Roofing systems, steel decking, and framing elements
● Agricultural facilities including swine containment, hoop buildings, grain bins, and silos
● Greenhouse structures and horticultural framing
● Industrial HVAC ducting, cooling towers, and ventilation components
● Solar racking, cable trays, and switch boxes
● School bus decking, swimming pool structures, and sign posts
● Guardrail facades, sound / wind / snow barriers, and coastal-environment installations
A1: Two standard formulations are offered: 3% Mg / 11% Al for maximum corrosion protection, and 1% Mg / 1% Al for balanced formability and durability. Custom coating weights can be discussed for volume orders.
A2: Zinc-Aluminum-Magnesium Alloy Coated Steel provides 10 to 20 times the corrosion resistance of standard hot-dip zinc-coated sheet and 5 to 8 times the corrosion resistance of hot-dip zinc-5% aluminum sheet, based on salt-spray testing, with added cut-edge protection.
A3: It is widely used for body panels, floor pans, reinforcements, chassis brackets, and structural components where long-term corrosion resistance and high-speed press formability are required.
A4: Thickness spans 0.3 mm to 2.5 mm, width spans 600 mm to 1250 mm, lengths are cut to order, and coils are wound to 508 mm or 610 mm IDs at 3 to 5 tons per coil.
A5: Yes, the export team supplies finished products directly, handles import customs clearance on the buyer's behalf, and has extensive experience serving the Philippine market and other overseas regions.
