4, Colors: Can do as your requirement We are the first one to pass CTC of national testing certification center of building materials.

5. Good quality for Benting:

6. Polyester coating ingle coating, one layer, 18μm; double coating, two layers, 25~27μm. PVDF coating: two layers of PVDF coating, at least 25μm, and if required, it will be covered by another layer of varnish, 35μm in total.

Color Match:

1. For custom' color requests, we can deal as following:
