Why choose Z275 galvanized steel coil?
1. Super strong anti-corrosion protection system
Zinc layer thickness: 275g/m² on both sides (180g/m² for conventional products in the industry)
Salt spray test: Passed 3000 hours of neutral salt spray test (ASTM B117 standard)
Service life: More than 40% longer than ordinary galvanized steel coils
2. Diversified surface treatment processes
| 0.5-1.2μm | Home appliance panels, precision parts. | |
| 1.5-2.5μm | Building exterior walls, industrial equipment. | |
| Zinc spangle-free surface | <=1.0μm | Automobile chassis, high-end decoration. |
3. Excellent processing performance
Elongation >=18% supports various processing methods such as stamping, bending, welding, etc., and the scrap rate is reduced by more than 30%.
| 0.3-3.0mm | ±0.03mm | |
| 5-15 tons/roll | ||
| 80-180 |
Z275 galvanized steel coil is a cold-rolled steel sheet treated by hot-dip galvanizing process, with a zinc layer weight of 275g/㎡ (double-sided), and has excellent anti-rust and corrosion resistance.As a core material in the fields of construction, home appliances, automobile manufacturing, etc., its high cost performance and long life are widely recognized by the market.
As industrial materials continue to upgrade, Z275 galvanized steel coil has become the preferred material in the fields of construction, automobile manufacturing, and home appliance production due to its excellent anti-corrosion performance and outstanding mechanical strength.
As a high-end galvanized product that meets international standards, this product adopts advanced continuous hot-dip galvanizing process, and the zinc layer weight is strictly controlled at 275g/m² (double-sided), which can maintain an effective anti-corrosion period of more than 10 years in harsh environments.
