Quality Control & Shipping Case
Rubber-coated forming rollers are used to help reduce paint scratching and coating abrasion during processing.
Paint thickness, solvent resistance, gloss, and color are checked against the confirmed order specification and approved sample.
Heavy-duty waterproof kraft paper and metal edge protectors shield sheets from humidity and transit impact.
Container bracing and securing are arranged to help reduce movement and friction damage during transportation.
Buyer Concern & FAQ
Q1: What is the primary difference between PPGI and PPGL roofing sheets?
PPGI.LTD supplies high-grade PPGL Roofing Sheets. The primary difference lies in the metallic coating substrate: PPGI uses a Galvanized (zinc) substrate for standard cathodic protection, whereas PPGL uses a Galvalume (55% aluminum-zinc alloy) substrate, offering superior long-term corrosion resistance and thermal heat reflectivity.
Q2: How do I choose between PE, HDP, and PVDF paint coatings for PPGL roofing sheets?
Choose PE (Polyester) for cost-effective standard applications; HDP (High-Durability Polyester) for enhanced scratch and weather resistance in moderate industrial environments; or PVDF for maximum UV protection and color retention in harsh coastal or extreme climates.
Q3: How do I choose the correct feeding width and effective cover width for my roofing project?
PPGL sheets are typically rolled from standard 1000mm or 1200mm feeding width coils into various wave or trapezoidal profiles. Due to side overlapping during installation, the final effective cover width will decrease. We provide detailed conversion guidance for accurate material calculations.
Q4: What sheet lengths are recommended for sea container transportation?
For safe and cost-effective sea shipping, we recommend keeping sheet lengths within 5.8 meters for 20-foot containers (20GP) and under 11.8 meters for 40-foot containers (40GP/40HQ) to fit inside standard container dimensions without bending or damage.
Q5: What international manufacturing standards and quality controls apply to PPGL Roofing Sheets?
Our production strictly complies with recognized international manufacturing standards, including ASTM A755, EN 10169, and JIS G3322. Strict in-line quality control is maintained throughout processing to verify 55% Al-Zn substrate adhesion, uniform paint film thickness, and dimensional profile precision.
