Quality Control & Shipping Case
Rubber-coated forming rollers prevent paint scratching and coating abrasion during processing.
Strict batch testing on paint thickness, MEK wipe resistance, gloss level, and color match.
Heavy-duty waterproof kraft paper and metal edge protectors shield sheets from humidity and transit impact.
High-tensile steel wire cabling and bracing ensure zero movement or friction damage inside containers.
Buyer Concerns (FAQ）
Q1: What is the primary difference between PPGL and PPGI 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.
Q2: How do I choose between PE, HDP, and PVDF paint coatings for PPGL roofing sheets?
A: Feeding width is the initial flat GI 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.
Q3: How do I choose the correct feeding width and effective cover width for my roofing project?
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.
Q4: What sheet lengths are recommended for sea container transportation?
A: Yes. We specialize in ultra-thin and full-hard roofing sheets starting from 0.115 mm, with zinc coating weights ranging from Z30 up to Z275 g/m² to meet different budget and durability requirements.
