Hlau xaim qhuav yog yooj yim, dav siv thiab tsim dhau. Cov hlau los yog xaim (qhov sib piv hauv cov lag luam "hlau mesh lag luam") yog cov hlau hlau dua cov khoom siv dua cov khoom siv, cov ntaub ntawv siv los ntawm kev xaiv cov roj carbon zoo lossis cov xim tsis muaj zog. Feem ntau, Hlau Hlau yog tsim los tsim cov txheej txheem xws li phaj tev, pickling, ntxuav, saponification, drying, kos, ntuav, txias, pickling, ntxhua, galvanizing, ntim thiab cov zoo li tsim hlau Hlau ingot (ingot) .
Daim Ntawv Thov Tam sim no, cov xov hlau thiab Hlau Hlau feem ntau siv rau hauv cov txheej txheem kev sib tw thiab cov khoom siv. Nyob rau hauv 1976, Guangzhou galvanized hlau hlau hoobkas hauv lub teb chaws ua ntej thov electrolytic pickling, siab kub ntxhov, daim npav hluav taws xob tshiab ntawm kev siv tshuab tshiab ntse xov hlau nruam cov khoom, kev kos duab los ntawm kev sib tshuam ntawm cov khoom sib txuas mus rau kev ua haujlwm tsis tu ncua, Reduced hlau noj. Lub sij hawm ntawd, cov xov tooj hlau xaim hluav taws xob muaj peev xwm tsim hlau hlua, qib qis hlau hlau, kaus steel hlau, caij nplooj ntoos hlav steel hlau, tsheb kauj vab ej caij nplooj ntoos hlav xaim thiab lwm yam khoom. Lub xyoo pua 20th, 80 xyoo, lub stapler nrog kub-poob qis carbon steel, kiv cua mesh npog xaim, carbon qauv hlau xaim, txaj xaim, thiab lwm yam kuj tau tuaj tawm. Cov hlau xaim tom qab tiv thaiv kom ncua kev txuas ntxiv ntawm cov hlau kom cov khoom muag muag ntau dua kom muaj lub zog ntawm daim ntawv thov ntawm cov hlau. Tom qab electro-galvanized kub-dip galvanized. Plating tooj liab thiab lwm plhom siv thiab xaim mesh ntau lawm. Qhov cuab yeej ntawm kev siv txoj hlua ruaj khov hlau Tom qab plating, tom qab plating thiab lwm txoj kev, tom qab kev kho mob ntawm txoj hlua hlau los yog xaim mesh muaj zoo tiv thaiv corrosion, tus yam ntxwv oxidation, yuav siv rau kev tsim, roj av, tshuaj, aquaculture , vaj tiv thaiv, zaub mov ua thiab lwm yam kev lag luam kev lag luam, thiab rwb thaiv tsev thiab lwm yam.
