A: We offer four mainstream coatings: PE (polyester), SMP (silicone-modified polyester), HDP (high weather-resistant polyester), and PVDF (fluorocarbon).
PE: 10-15 years of weather resistance, highest cost-performance ratio.
SMP/HDP: 15-20 years, stronger corrosion resistance.
PVDF (fluorocarbon): 20-30 years and above, longest color retention period, suitable for high-end buildings and coastal areas. Specific lifespan depends on the environm
A: Full customization is supported!
Colors: RAL full color range + customer-supplied sample color matching (ΔE≤1.0)
Specifications: Thickness 0.2-1.5mm, Width 600-1500mm, Length any
Surface: Glossy/Matte/Embossed/Wood Grain/Brick Grain/Brushed, etc.
Minimum Order Quantity: 5 tons (regular orders), special specifications/small batches are negotiable.
A: 55% aluminum-zinc alloy (GL) has 3-5 times the corrosion resistance of ordinary zinc (GI), making it especially suitable for coastal, high-humidity, and acid rain-prone areas.
GI is more suitable for dry inland environments and is less expensive.
Our recommendation: GL is the first choice for coastal/export projects, while GI is an option for inland projects.
A: Quotes are based on the latest steel futures prices, exchange rates, shipping costs, and customer requirements (thickness, coating, quantity).
A normal quote is valid for 7-10 days (due to significant fluctuations in steel prices).
Larger prices can be locked in for larger orders or long-term partnerships.
