FAQ
What is the difference between GI sheet and PPGI sheet for roofing?
GI (Galvanized Iron) sheet has a zinc coating for corrosion resistance, while PPGI (Pre-Painted Galvanized Iron) sheet has an additional color-painted layer on top of the zinc for enhanced aesthetics and extra protection. For long-lasting galvanized roofing in harsh climates, GI is a robust and economical choice.
What zinc coating is best for roofing sheets in coastal areas?
For coastal areas with high salt exposure, we recommend a heavier zinc coating, typically 180 g/m² or higher (such as Z275), to provide maximum protection against corrosion for your zinc roof sheet Africa and other coastal projects.
Can you supply custom lengths for corrugated GI roofing?
Yes, we specialize in supplying corrugated GI roofing in custom lengths to minimize on-site waste and installation time. Please provide your required length profiles when requesting a quote.
What is the standard packing for export to prevent damage?
To prevent damage during ocean freight, we pack our galvanized roofing sheets securely in wooden crates or with protective steel straps and corner guards. Waterproof paper wrapping is also used to guard against moisture.
