Selecting the right direct PPGI manufacturer is critical for your supply chain. Here’s why global buyers trust ChinaCNU Steel.
As a premier PPGI supplier Qingdao based, our pricing is structured to provide maximum value. We offer FOB Qingdao port pricing, which includes standard packing and local charges. The final price per ton depends on specifications such as steel grade, thickness, zinc coating weight, paint type (PE, PVDF, HDP), and color. Market fluctuations in raw materials also influence daily rates. For the most accurate and competitive factory price, we provide free, no-obligation quotes tailored to your exact requirements. Simply contact us with your specs for a detailed offer within 24 hours.
PPGI (Pre-Painted Galvanized Iron) coil is a GI (Galvanized Iron) coil that has undergone an additional process where a colored paint coating is applied on top of the zinc layer. This paint provides extra corrosion protection, UV resistance, and aesthetic color options, making PPGI ideal for visible architectural applications, whereas standard GI coil is often used as a base material or where paint is applied later.
Selecting the correct paint coating depends on your environment and performance needs. Polyester (PE) offers good durability and color retention at a cost-effective price for general building cladding. Silicon Modified Polyester (SMP) provides better UV resistance for longer-lasting color. For harsh industrial or coastal environments, Polyvinylidene Fluoride (PVDF) or High Durability Polyester (HDP) coatings offer superior resistance to chalking, chemicals, and weathering. Our technical team can advise based on your specific PPGI coil application.
To ensure safe transit to destinations like Africa or South America, our standard export packing for PPGI steel coils includes a moisture-resistant paper inner wrap, followed by a robust plastic or woven fabric outer cover. The coil is then securely strapped with steel bands onto a sturdy wooden pallet or a steel saddle. This method prevents rust, moisture damage, and deformation during shipping. Special packing requests can be accommodated for sensitive logistics routes.
Yes, as a direct PPGI manufacturer with in-house processing lines, we regularly produce custom-sized PPGI sheets and coils. We can slit coils to specific widths and cut sheets to exact lengths required for your construction project, roofing panels, or appliance parts. Providing your detailed dimensional requirements and volume during inquiry helps us optimize production and provide the most accurate pricing and lead time for your custom pre-painted steel order.
