Product Q&A

Q:What is the essential difference between GI and Galvalume roof sheets?

GI is single pure zinc coating with lower cost, suitable for inland common projects; Galvalume is 55% aluminum-zinc alloy coating with 2-4 times longer anti-corrosion life, specially for coastal and heavily polluted industrial areas.

Q:Can GI and Galvalume be mixed used on one building?

Yes. Use Galvalume for windward coastal facades and GI for rear hidden warehouse roofs to balance cost and durability.

Q:Do Galvalume sheets need edge sealing after cutting?

Recommended. Seal cut edges with anti-rust paint or sealant to maximize its full service life; GI has stronger natural edge protection without mandatory sealing.

Q:Which coating weight is recommended for coastal Galvalume projects?

Choose AZ200 or AZ275 high coating weight Galvalume for strong salt fog resistance.

Q:What thickness is most popular for general building roofing?

0.4mm, 0.45mm and 0.5mm are the most cost-effective universal thicknesses.
