PPGI steel kaujyog galvanized steel substrate coated nrog ib txheej ntawm cov organic txheej khoom, vim nws cov khoom zoo heev los tiv thaiv corrosion, huab cua tsis kam thiab zoo nkauj tsos, dav siv hauv kev tsim kho, khoom siv hauv tsev, tsheb thiab lwm yam lag luam. Cov keeb kwm ntawm cov xim coated rolls hnub rov qab mus rau thaum ntxov xyoo pua 20th thiab yog thawj tsim los daws cov teeb meem corrosion ntawm galvanized steel daim hlau nyob rau hauv ib puag ncig ntub. Nrog rau kev loj hlob ntawm galvanizing tshuab, galvanized steel tau dav siv nyob rau hauv kev ua lag luam.
Nyob rau xyoo 1960, lub tswvyim ntawmxim coated yobpib tshwm sim, thiab cov tuam ntxhab siv cov txheej txheem txheej txheem los ntxiv cov xim thiab cov txheej txheem tiv thaiv rau galvanized steel daim hlau, ua tau raws li qhov xav tau ntawm kev ua lag luam rau kev zoo nkauj thiab kav ntev. Thaum lub sijhawm no, cov txheej txheem tseem ceeb siv feem ntau yog cov roj-raws li txheej txheej, txawm hais tias lawv muaj qee qhov zoo hauv kev ua haujlwm, tab sis kev tiv thaiv ib puag ncig thiab kev nyab xeeb tseem yuav tsum tau txhim kho.
Nyob rau xyoo 1970 thiab 1980s, nrog rau kev nce qib ntawm cov khoom siv hluavtaws thiab txheej txheej txheej txheem, PPGI cov txheej txheem tsim tau raug txhim kho tas li, adhesion, corrosion kuj thiab huab cua tsis kam ntawm txheej txheej tau txhim kho, thiab ntau yam xim thiab textures ntawm txheej tau tshwm sim nyob rau hauv kev ua lag luam kom tau raws li tus neeg xav tau kev pab ntawm cov neeg siv khoom sib txawv. Lub sijhawm no, PPGI tau pib siv dav hauvtsim lub ru tsev thiab phab ntsa, ua ib feem tseem ceeb ntawm niaj hnub architecture.
Tom qab nkag mus rau hauv lub xyoo pua 21st, kev txhawb nqa thoob ntiaj teb kev paub txog ib puag ncig tau ua rau kev lag luam pleev xim los txhim kho cov kev coj ntawm ntsuab thiab kev tiv thaiv ib puag ncig. Ntau lub tuam txhab tau pib siv cov txheej txheem dej thiab cov txheej txheem inorganic los txo lawv cov kev cuam tshuam ib puag ncig. Qhov kev hloov no tsis tsuas yog txhim kho kev ruaj ntseg ntawm PPGI, tab sis kuj ua rau nws muaj kev sib tw ntau dua hauv kev ua lag luam. Lub sijhawm no, daim ntawv thov teb ntawm PPGI tau nthuav dav ntxiv kom suav nrog ntau qhov kev lag luam xws li cov khoom siv hauv tsev thiab cov tsheb sab hauv, uas qhia txog nws qhov zoo tshaj plaws hauv ntau haiv neeg thiab kev yoog raws.

Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev cia siab rau yav tom ntej ntawm PPGI yog qhov dav. Kev nthuav qhia cov ntaub ntawv tshiab thiab thev naus laus zis yuav thawb PPGI mus rau kev ua tau zoo dua thiab kev txhim kho ib puag ncig zoo dua. Nrog rau kev nce ntxiv ntawm kev tsim kho kom ruaj khov thiab tsim ntsuab, PPGI xav tias yuav ua lub luag haujlwm loj dua hauv cov cheeb tsam no.
Los xaus,PPGI xim coated yobtau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam niaj hnub nrog lawv lub cev zoo nkauj thiab zoo nkauj tsos. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev hloov pauv hauv kev xav tau ntawm kev ua lag luam, daim ntawv thov ntawm PPGI yuav txuas ntxiv nthuav dav, coj ntau txoj hauv kev rau txhua qhov chaw ntawm lub neej.
