Ikhoyili yentsimbi yeppgi ikwabizwa ngokuba yicoil yentsimbi epeyintwe yangaphambili (imfutshane ethetha "ikhoyili yeppgi"), isebenzisa igalvanized njenge substrate.Emva kokunyangwa komphezulu (ukususwa kwekhemikhali kunye nokuguqulwa kweekhemikhali), intsimbi engwevu ye-ppgi igqunywe ngomaleko okanye iileya ezininzi zokugquma, ngokubhaka kunye nokunyanga, emva koko ube yiPPGI. i-zinc layer idlala indima ekugubungeleni nasekukhuseleni i-coil yensimbi ehlanganiswe nombala, ukukhusela i-coil yensimbi ekugqweseni, kunye nobomi bayo benkonzo malunga namaxesha angama-1.5 ubude kunalowo we-galvanized coil.
Ifilimu yepeyinti esinokuyenza i-10-30microns.Ukuphakama kwefilimu yepeyinti, ixesha elide ubomi benkonzo yombala.
Izinto zokupeyinta ziyi-PE, SMP, HDP, PVDF, ects.
Umbala we-Pupolar we-ppgi yentsimbi yekhoyili: iwayini ebomvu (i-ral3005), idangatye elibomvu (i-ral3000), i-Ruby ebomvu (i-RAL3003), i-Signal ebomvu (i-RAL 3001), i-Coral ebomvu (i-RAL 3016), i-Red Traffic (RAL 3020)
