Buyer Concern & FAQ
Q1: What products are included in PPGI.LTD's metal coil and roofing catalog?
PPGI.LTD supplies GI, GL, PPGI, PPGL, Prepainted Aluminum (PPAU) coils, specialty coated metal, and profiled roofing sheets. Product specifications can be selected according to substrate, thickness, width, coating weight, paint system, color, surface finish, profile, and end-use requirements.
Q2: How are steel coils packed and loaded for ocean shipment?
Steel coils are packed with protective materials such as waterproof wrapping, steel covers, edge protection, and steel strapping according to product and shipping requirements. For container shipments, loading quantity depends on coil weight, coil dimensions, container payload, destination regulations, and port weight limits.
Q3: How do I select the right substrate and coating for my market?
Galvanized Steel (GI) is widely used for general construction, roofing, and fabrication applications. Galvalume (GL) is commonly selected where additional heat and corrosion resistance are required. PPGI and PPGL add painted surface protection and color options, while Prepainted Aluminum (PPAU) provides a lightweight option for selected architectural and industrial applications. Paint systems such as PE, SMP, and PVDF can be selected according to project environment and performance requirements.
Q4: How are product quality and specification tolerances controlled?
Thickness, coating condition, surface quality, dimensions, and other agreed specifications are checked during production. Products can be supplied according to applicable standards such as EN 10346, ASTM A653, ASTM A792, and JIS G3302, depending on the material type, grade, and customer requirements.
Q5: What are the production lead time and ordering process?
Production lead time depends on product specifications, order quantity, raw material availability, and the current production schedule. For quotation, buyers can provide key requirements such as product type, thickness, width, coating weight, color, coil weight, quantity, and destination through WhatsApp or email.
