PPGI iyishidi steel elinombala elinokwakhiwa kwe-GI (Iron e-Galvanized) njengemathiriyeli eyisisekelo, kanti i-PPGL iyishidi steel elinombala elinokwakhiwa kwe-GL (Galvalume) njengemathiriyeli eyisisekelo. I-coatings organic efakwe ebusweni (njengokuthi polyester, silicon-modified polyester, kanye ne-fluorocarbon) inikeza ukumelana okuhle nezimo zezulu, ivumela imathiriyeli ukuba ibekezelele imisebe ye-UV, imvula ye-asidi, nezinye izinto ezisemvelweni, iqinisekisa ukugcina umbala nokukhanya isikhathi eside.
PPGI isebenzisa insimbi egaywe ngensimbi njengemathiriyeli eyisisekelo, nezingxube ze-zinc ezinikeza ukuvikelwa okuhle kokumelana nokugqwala, okwenza kube kufanelekile ezindaweni ezijwayelekile zokugqwala. PPGL, ngakolunye uhlangothi, isebenzisa insimbi egaywe ngensimbi ye-aluminium-zinc njengemathiriyeli eyisisekelo, futhi ingxube ye-aluminium-zinc (55% aluminium, 43.4% zinc, 1.6% silicon) inikeza ukumelana nokugqwala okuhle, ikakhulukazi ikhuluma kahle ezindaweni ezinzima.
Zonke i-PPGI ne-PPGL zikhombisa ukusebenza kahle kokucubungula, okwenza zifaneleke ekwenzeni izimo eziyinkimbinkimbi ngokuhlinzwa, ukujolisa, nokuhlanza. Ukubopha okuqinile kwemigqa kuvimba ukuhamba ngesikhathi sokucubungula. Ngaphezu kwalokho, inqubo yokupenda ngaphambi kwepende yehlisa isidingo sokupenda endaweni, yehlisa ukukhishwa kwezinto eziphilayo eziguquguqukayo (VOCs) futhi ihlangabezana nezidingo zemvelo.
