Buyer Concerns (FAQ）
Q1: How do I choose between PE, HDP, and PVDF paint coatings for PPGI roofing sheets?
A: PE (Polyester) is the cost-effective standard for regular environments. HDP (High-Durable Polyester) offers superior UV resistance and color retention for hot or sunny regions. PVDF (Fluorocarbon) provides exceptional chemical and chalk resistance, making it ideal for aggressive coastal or heavy industrial environments.
Q2: What is the difference between corrugated wave sheets and trapezoidal (box profile/IBR) roofing sheets?
A: Corrugated sheets feature traditional round wave profiles suitable for standard residential or agricultural roofs, while trapezoidal (box profile / IBR) sheets offer higher water discharge capability and structural strength, making them ideal for industrial facilities and commercial roofs.
Q3: How do I choose the correct feeding width and effective cover width for my roofing project?
A: Feeding width is the initial flat PPGI coil width (e.g., 1000mm or 1200mm). After roll forming, the effective cover width (e.g., 800mm or 900mm) represents the actual installation coverage per sheet after overlapping. We assist you in calculating sheet quantities to minimize material waste.
Q4: What sheet lengths are recommended for sea container transportation?
A: For standard 20ft containers, maximum length is usually kept within 5.8 meters (5800mm); for 40ft containers, lengths up to 11.8 meters (11800mm) are recommended to maximize space utilization and cut ocean freight costs.
