Cov ntsia hlau thiab hlau ntsia hlau loj tshaj qhov sib txawv tshaj plaws hauv kev siv qhov sib txawv. Cov Khaub Ncaws Nus Feem ntau yog siv rau cov ntoo ntawm qhov txuas, nws yog ua los ntawm General cov pa roj carbon steel qis, kev ua kom yooj yim, txo tus nqi. Cov khoom siv steel ntsia hlau tuaj yeem tawm mus txhim kho nws lub zog thiab tawv, kev ua cov khoom hnyav, cov nqi tsim khoom lag luam ntau. Vim tias nws lub zog siab thiab tawv tawv, nws tuaj yeem siv los txuas cov hlau, pob zeb, av ci. XWM TXHEEJ: Hlau Nails yog cov tuab, cov rau tes nquag yog nyias. Cov ntsia hlau steel feem ntau yog galvanized, xim yog tsaus dawb, cov ntsia hlau zoo li qub galvanized thiab tsis galvanized, galvanized xim feem ntau kuj kaj lug, kuj tseem kub kub galvanized, cov xim tsis yog li dawb, kuj yog tsaus dawb lossis grey, tab sis xws li yog cov tuab, muaj galvanized lossis passivated. Cov ntsia hlau sab nrauv yog cov khoom siv hlau xaim siv los ua kom ceev cov khoom. Siv dav hauv kev lag luam, kev ua liaj ua teb, kev tsim kho, pej xeem thiab lwm yam, feem ntau yog siv rau cov khoom siv axial sib cais me me radial shear quab yuam tsis loj cov khoom ruaj khov, nrog kev ua kom yooj yim, siv tau yooj yim, ntsia nrawm thiab lwm yam. Qhov ntau ntawm cov ntsia hlau steel yog ntau yam, cov duab tsis sib txawv, tuaj yeem xaiv raws li kev siv lub hom phiaj sib txawv thiab kev thov. Cov ntau yam tseem ceeb yog cov ntsia hlau, ntsia hlau ntsia, tiaj tus ntsia hlau ntsia, ntsia hlau ntsia hlau, ntswj ntsia hlau, ntsia hlau, ntsia hlau ntsia hlau, ntsia hlau, ntsia hlau rau cov qhov txhab, kho cov rau tes Cov khoom lag luam muaj qhov dav dav raws li cov duab, kuj raws li saum npoo muaj txheej txheej kom paub qhov txawv (xws li cov ntsia hlau galvanized, cov rau tes polished, thiab lwm yam). Qhov feem ntau siv thiab siv dav dav yog cov hom phiaj dav dav dog dig round ntsia hlau.
