FAQ
Q:What is aluminum-zinc/galvanized steel?
A:This is a type of steel coated with a layer consisting of 55% aluminum, 43.4% zinc, and 1.6% silicon. The aluminum layer provides a corrosion-resistant barrier, while the zinc layer acts as a sacrificial protective layer. This combination offers a service life that is 2 to 6 times longer than that of standard galvanized steel.
Q:What does 1250mm width mean for my project?
A:1250mm is a standard construction width that matches common roofing and cladding modules. Less cutting, less waste, faster installation.
Q:What thicknesses do you stock?
A:0.12mm to 3.0mm. Most popular: 0.30mm, 0.40mm, 0.50mm for roofing. Thicker gauges for structural use.
Q:Can I get different inner diameters?
A:Yes. 508mm or 610mm standard. Others on request.
Q: How can I get your quotation as soon as possible?
