Q1: What is the difference between galvanized steel coil and galvalume steel coil?
A: Galvanized coil adopts pure zinc coating, while galvalume uses 55% Al-Zn-Si alloy coating. Galvalume owns around 3 times better corrosion resistance, and galvanized coil has more cost advantages for inland projects. Galvalume Steel Strip and Strip Gl are our popular galvalume products.
Q2: Can we customize zinc coating weight for our roofing projects?
A: Yes, Z40-Z275 g/m² options are available. We can recommend proper zinc weight according to your local service environment. We also support custom specifications for Galvalume Steel Strip and Strip Gl.
Q3: What is your regular production lead-time?
A: Normally 10-20 working days after receiving deposit or original L/C. Stock goods of galvanized coil, Galvalume Steel Strip and Strip Gl can be delivered in shorter cycles.
Q4: Can you provide small samples for quality evaluation?
A: Small cut-off samples can be offered. The buyer shall bear the sample freight cost, including samples of Galvalume Steel Strip and Strip Gl.
