Saboda sun yi amfani da layers daban-daban na waje. Polyethylene uku Layer Tsarin Kariya Layer wanda aka sani da uku LayerPE,Yana da ci gaba da lalata tsare fasahar da aka gabatar daga kasashen waje a 'yan shekarun nan. Yana da cikakken sunan narkewa bonding epoxy/Extrusion polyethylene tsarin karewa Layer,Tsarin ya kunshi masu zuwa uku layers: kasa layer ne narkewa bonded epoxy(60—80μm); tsakiyar Layer ne mai namawa(170—250μm); surface layer ne extruded polyethylene(game da2mm). Total kauri na kariya layer ne mafi girma fiye da2.2—2.9mm. A cikin 3 layers tsari,Babban rawar epoxy substrate shine: samar da ci gaba da rufi film,Kai tsaye haɗuwa da karfe bututun surface,Yana da kyakkyawan chemical juriya lalata da kuma anti cathode stripping halaye; Ayyukan ƙungiyar da ke aiki tare da matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin matsakaicin,Tabbatar da cewa dukan lalacewa rigakafi layer yana da kyau adhesion a mafi girma zazzabi.
