PPGI xaashida jiingadaha ah ee soo saaraha Shiinaha qiimo jaban

PPGI xaashida jiingadaha, sidoo kale loo yaqaan xaashida profiled, waa xaashi muuqaalaysan oo ka samaysan mowjado kala duwan iyadoo la rogayo iyo go'yaal qabow-duuban sida xaashi bir midabaysan iyo xaashi galvanized ah. Cutubka joogtada ah, birta birta ah ee qabow-duuban iyo birta galvanized (electro-galvanized and hot-dip galvanized) ayaa loo isticmaalaa sida walxaha aasaasiga ah, qaybta iskutallaabtu waa V-qaabeeya, U-qaabeeya, trapezoidal ama waveforms la mid ah. Dusha sare ee birta waxaa lagu dahaadhay dahaarka organic. Waxay leedahay faa'iidooyinka muuqaalka quruxda badan, midabka dhalaalaya, xoogga sare, caabbinta daxalka wanaagsan, iyo habaynta iyo samaynta habboon. Waxa kale oo ay yarayn kartaa kharashaadka iyo wasakhowga isticmaalayaasha. Waxaa jira noocyo badan oo taarikada midabka leh, oo ku saabsan in ka badan 600 oo nooc. Taarikada midabka leh ayaa leh faa'iidooyinka labadaba polymers organic iyo birta birta ah. Waxay leeyihiin midabayn wanaagsan, qaabaysan, iska caabin daxalka, qurxinta, iyo taarikada birta. Xoog sare iyo hab fudud oo fudud, waxaa si fudud loogu farsamayn karaa shaabadeynta, goynta, foorarsiga, iyo sawirka qoto dheer. Tani waxay ka dhigaysaa badeecooyinka ka samaysan birta dabiiciga ah ee dahaarka leh inay leeyihiin karti aad u wanaagsan, qurxinta, socodsiinta iyo adkeysiga.
