Buyer Concern & FAQ
Q1: How do I choose between PE, HDP, SMP, and PVDF coatings for PPGI Roofing Sheet?
PE (Polyester) is widely used for general roofing applications where cost and standard outdoor performance are important. HDP and SMP can be selected where improved weather and UV resistance are required, while PVDF is commonly used for projects requiring higher weatherability and chemical resistance. The appropriate coating system depends on the project environment, expected service conditions, color, gloss, and budget.
Q2: What is the difference between corrugated and trapezoidal PPGI roofing sheets?
Corrugated roofing sheets use a rounded wave profile and are widely used for residential, agricultural, and general roofing applications. Trapezoidal and IBR profiles use deeper or wider ribs and are commonly selected for industrial and commercial roofing. Actual structural performance depends on sheet thickness, steel grade, rib geometry, support spacing, and installation design.
Q3: How do I choose the feeding width and effective cover width for my roofing profile?
The effective cover width is determined by the feeding width, roll-forming profile, rib dimensions, and overlap design. Different molds can produce different cover widths from the same raw coil width. Profile dimensions can be confirmed before production according to the required roofing design.
Q4: What roofing sheet lengths can be supplied for container shipment?
PPGI roofing sheets can be cut to customized lengths according to project and transportation requirements. Suitable shipping length depends on the container type, loading method, bundle dimensions, destination requirements, and handling conditions. Length and loading arrangement should therefore be confirmed before production.
Q5: What standards and quality checks are available for PPGI Roofing Sheets?
PPGI Roofing Sheets can be supplied according to applicable standards such as ASTM A755, EN 10169, or JIS G3312, depending on the required substrate, coating system, grade, and order specification. During production, thickness, surface condition, paint coating, profile dimensions, and other agreed specifications can be checked according to the order requirements.
