Product feature
 
 
 
 
Zn-Al-Mg coating steel has better corrosion resistance. The increase of Al and Mg content
in a certain range makes the corrosion resistance of Zn-Al-Mg coating steel sheet increase
several times higher than that of GI.
With low friction coefficient and stable friction characteristics, it is very favorable for
punching. It can reduce the amount of wear on the coating, thereby reducing the part's
pulling defects.


The Zn-Al-Mg coating steel has good welding performance. The addition of magnesium
can reduce the spatter of the weld attachment in the laser welding process and improve
the welding performance.
 
Application
 
 
 
1. Construction & Building Materials
- Roofing & Wall Cladding: 
Used for industrial plants, warehouses, airports, and other structures requiring weather-resistant panels. Performs exceptionally in harsh climates (e.g., acid rain, salt spray). 
- Prepainted Substrate: 
Serves as a base material for prepainted steel (e.g., PVDF or PE coatings) in high-end architectural façades. 
- Steel Structure Components: 
Lightweight steel frames, purlins, connectors, and brackets, combining durability with reduced weight. 
2. Industrial Manufacturing -Automotive Industry: Door inner panels, chassis parts, fuel tanks. Enhanced corrosion resistance extends component lifespan and lowers maintenance costs. - Appliances & Electronics: Refrigerator housings, washing machine panels, outdoor AC unit casings. Offers smooth surfaces for painting or laminating. - Machinery & Equipment: Cable trays, ventilation ducts, industrial shelving. Resists abrasion and supports easy stamping/forming. 
3. Infrastructure & Energy - Solar Mounting Systems: Used in solar farm structures, withstanding prolonged UV exposure, rain, and saline-alkali soil environments. - Agricultural Greenhouses: Greenhouse frames and cladding. Resists humidity and fertilizer corrosion, lasting 2-3x longer than standard galvanized steel. - Transportation Infrastructure: Highway guardrails, tunnel linings, noise barriers. Meets high-strength and weather-resistance standards.
