    Frequently Asked Questions
    Q What is ZAM steel and how does it differ from standard galvanized steel?
    ZAM steel is a zinc-aluminum-magnesium alloy-coated steel that offers significantly superior corrosion resistance compared to standard galvanized steel. In salt spray tests, ZAM steel can last 5–10 times longer than conventional hot-dip galvanized steel, making it ideal for harsh marine and industrial environments.
    Q What are the available thickness and width ranges for ZAM steel coils?
    ZAM steel coils are available in thicknesses ranging from 0.3mm to 3.0mm and widths from 600mm to 1500mm. The double-sided coating weight ranges from 60 to 275 g/m², allowing flexibility for various application requirements.
    Q What is the self-healing property of ZAM steel?
    The magnesium content in the ZAM coating enables a self-healing effect. When the surface is scratched or cut, magnesium reacts to form a dense, stable protective layer over the exposed area, preventing further corrosion and extending the service life of the material.
    Q Which industries and applications are best suited for ZAM steel?
    ZAM steel is widely used in construction (roofing, wall panels, garage doors), home appliances (refrigerator and AC casings), automotive manufacturing (chassis parts), and agriculture (greenhouse frames, silos). Its combination of strength, formability, and corrosion resistance makes it highly versatile.
    Q What international standards does ZAM steel comply with?
    ZAM steel products can be produced in compliance with major international standards including ASTM (American), GB/T (Chinese), and JIS (Japanese) standards. Material selection prioritizes carbon content, elongation performance, and surface defect control to meet downstream processing requirements.
    Q Which export markets does your company serve for ZAM steel products?
    We supply ZAM steel to customers across Southeast Asia (Thailand, Singapore, Malaysia), the Middle East (Saudi Arabia, UAE, Oman, Egypt, Kuwait, Jordan), Africa (South Africa, Tanzania, Algeria, Ghana, Nigeria), and South America (Peru, Colombia, Ecuador, Chile). We provide customized solutions and technical support for global clients.
