Frequently Asked Questions (FAQ)
What is ZAM steel and how is it different from regular galvanized steel?
ZAM steel is a zinc-aluminum-magnesium alloy-coated steel that offers 5–10 times greater corrosion resistance than standard galvanized steel. The addition of aluminum and magnesium to the zinc coating significantly enhances durability and self-healing properties, making it ideal for harsh environments.
What coating weight options are available for ZAM steel?
ZAM steel is available with a double-sided coating weight ranging from 60 to 275 g/m². The appropriate coating weight depends on the application environment and required corrosion protection level.
What does the self-healing property of ZAM steel mean?
The magnesium content in the ZAM coating reacts with moisture and oxygen to form a stable, dense protective oxide layer over scratches or cut edges. This self-healing effect helps prevent rust from spreading, significantly extending the service life of the material.
Which industries commonly use ZAM steel?
ZAM steel is widely used across construction (roofing, wall panels, garage doors), home appliances (refrigerator and AC casings), automotive (chassis components), and agriculture (greenhouse frames, silos), thanks to its excellent corrosion resistance and formability.
What international standards does your ZAM steel comply with?
Our ZAM steel products comply with major international standards including ASTM, GB/T, and JIS. We ensure strict quality control in carbon content, elongation, and surface defect management to meet diverse customer requirements worldwide.
Can ZAM steel be customized for specific thickness and width requirements?
Yes. We offer ZAM steel in thicknesses from 0.3mm to 3.0mm and widths from 600mm to 1500mm. Custom specifications are available upon request. Please contact our team for a tailored quote and technical support.
