Buyer Concerns (FAQ)
Q1: What is the main difference between PPGI and PPGL steel coils?
A: PPGI uses Galvanized (GI) steel as substrate, while PPGL uses Galvalume (GL) steel. PPGL offers superior corrosion resistance and heat reflectivity, leading to a significantly longer service life in harsh environments.
Q2: How do I choose the right paint coating (PE, SMP, PVDF) for my market?
A: PE is cost-effective for general construction; SMP offers better weather resistance; PVDF provides maximum UV and corrosion protection for severe coastal or industrial environments.
Q3: Can a protective film be applied to the Prepainted Galvalume Steel Coil surface?
A: Yes. We can apply a transparent or printed protective film (PE film) on the painted surface to prevent scratches during transportation, handling, and profiling.
Q4: What are the main applications for Prepainted Galvalume Steel Coil?
A: They are widely used for corrugated roofing sheets, sandwich panels, wall cladding, garage doors, rain gutters, and home appliance enclosures.
