Frequently Asked Questions

What is the difference between galvanized and galvalume steel?

Galvanized steel is coated with pure zinc, while galvalume (or aluzinc) contains 55% aluminum, 43.5% zinc, and 1.5% silicon. Galvalume offers superior corrosion resistance, especially in harsh environments.

Do you offer custom colors and patterns?

Yes. We have an in-house design team and can produce custom wood grain, marble, brick, and textured finishes using Printech and PVDF technologies.

What certifications do your products have?

Our factory is ISO9001 certified. Products comply with EN 10169, ASTM A755M, DIN, GB, and JIS standards. Testing reports are provided for every shipment.

What is the typical warranty period?

We offer a minimum 10-year warranty on standard PPGI products. Premium PVDF and FEVE coatings come with up to 50-year warranties depending on environmental conditions.

Can you slit coils to custom widths?

Yes. We offer precision slitting services for steel and aluminum coils to meet specific project requirements for frames, purlins, and roofing profiles.
