The full name of PPGI Coil is prepainted galvanized steel coil. It uses hot-dip galvanized steel as the substrate. After pretreatment, it is coated with PE, SMP, and PVDF coatings and then baked. Due to its excellent appearance and good corrosion resistance, it is eventually applied to roofing and siding, the corrosion resistance is related to the galvanizing weight, paint type, and paint thickness.

Get a QuoteIt’s price is based on the width and thickness of the coil, galvanizing weight, paint type, and paint thickness.
Width: 1260mm
Thickness: 0.6mm
Galvanized weight: 275g
Paint type: SMP
Topcoat thickness: 25 microns
The reference price for this specification is around $1,250 per ton. Note that many manufacturers will conceal the true specifications and quote the price of low-quality steel coil.
The substrate of PPGL coil is galvalume steel, and the substrate of PPGI coil is galvanized steel. Since galvalume is more corrosion-resistant than galvanized, PPGL Coil is more used in coastal areas and roofs that require longer life. PPGL Coil has been used to replace PPGI coil in North America. PPGI coil is more used in cold storage panels and roofing applications in hot areas.
The HS Code for PPGI Coil with a thickness of <1.5mm and a width of 600mm and above is 721070. Note that Japan has canceled tax refund, European and American regions should pay attention to whether imports from Japan need to pay tariffs
