Aluminium-zinc-plated magnesium coil can be used directly as a finished product or as a substrate for colour coated sheet. It is widely used in steel structure building enclosure systems, including roofing and walling materials such as roofs, walls, ceilings, and rolling doors for industrial plants, power plants, stadiums, airports, exhibition halls, and civil residential buildings. Additionally, its excellent formability and ductility make it suitable for manufacturing applications including pipelines, furniture, electrical appliance back plates, auto parts, and other industrial fields.

Application Scenarios
  • Construction: Used for roofing, walling, doors, and windows of buildings to provide excellent anti-corrosion protection while enhancing aesthetic appeal. Modern industrial factories and commercial buildings frequently utilize colourful coated steel coils as exterior wall materials, combining modern aesthetics with building durability.
  • Home Appliance Field: Used for manufacturing refrigerator, washing machine, air-conditioner, and other appliance shells, meeting diverse consumer requirements.
  • Transportation Field: Applied in manufacturing shells and interior components for cars, trains, ships, and other vehicles, offering excellent decorative and corrosion-resistant properties.
  • Advertising and Signage Field: Used for billboards, signage, and displays with vibrant colours and superior durability.

Frequently Asked Questions
What is the difference between ZAM steel and galvanized steel?
ZAM steel provides much higher corrosion resistance, especially at cut edges, compared to traditional galvanized (GI) steel.
What does ZAM stand for?
ZAM stands for Zinc (Zn), Aluminum (Al), and Magnesium (Mg), the three key elements in the coating.
Why is magnesium added in the coating?
Magnesium improves self-healing performance at cut edges and enhances long-term corrosion resistance.
What is the typical coating composition of Zn-Al-Mg steel?
Usually: Zinc 85-96%, Aluminum 1-11%, Magnesium 0.2-4%, depending on grade and manufacturer.
What standards apply to Zn-Al-Mg steel coil?
Common standards include EN 10346, ASTM A1046/A1046M, and JIS G 3323.
