FAQ

Common questions.

PPGI or PPGL — what is the difference?

PPGI uses a zinc (GI) substrate; PPGL uses an aluminium-zinc (galvalume) substrate with better heat and corrosion resistance — often preferred for long-life roofing.

Which paint system for the Gulf?

SMP or HDP offer better UV and chalking resistance than standard polyester; PVDF is the premium option for long colour retention.

What is the minimum order per colour?

It varies by mill — typically one coil run per colour and thickness. Share your colour list and we will confirm.
