FAQ
What is the difference between GI and PPGI metal roofing sheets?
GI (Galvanized Iron) sheets have a protective zinc coating that provides excellent corrosion resistance for a steel roofing sheet. PPGI (Pre-Painted Galvanized Iron) sheets feature a galvanized base with an additional layer of colored paint on top, offering enhanced aesthetics, additional protection against the elements, and a wider choice of colors for your corrugated metal roof project.
What is the typical lifespan of your metal roofing sheets in coastal areas?
Our high-zinc coating grades (e.g., Z275) are specifically designed for harsh environments. A properly installed GI PPGI roof from our range can have a service life of 20-30 years in coastal regions, depending on the specific atmosphere and maintenance.
Can you produce custom profiles for the corrugated metal roof?
Yes, as a professional manufacturer, we have the capability to customize roll-forming profiles. Whether you need a specific tile shape, wave height, or trapezoidal design for your metal roofing sheet China order, we can produce it based on your provided drawings or specifications.
What are the payment and shipping terms for export orders?
We accept secure payment methods including T/T (Telegraphic Transfer) and L/C (Letter of Credit). Shipping is typically arranged as FOB Tianjin, where we handle all costs and procedures to get your goods loaded onto the vessel.
