Bright tiav
Bright fasteners tsis muaj txheej txheej los tiv thaiv cov hlau thiab muaj kev tiv thaiv corrosion yog tias raug cov av noo siab lossis dej. Lawv tsis pom zoo rau kev siv sab nrauv lossis hauv cov ntoo kho, thiab tsuas yog siv rau sab hauv uas tsis muaj kev tiv thaiv corrosion. Bright fasteners feem ntau siv rau sab hauv thav duab, luas thiab ua tiav daim ntawv thov.
Kub Dip Galvanized (HDG)
Kub dip galvanized fasteners yog coated nrog ib txheej ntawm Zinc los pab tiv thaiv cov hlau los ntawm corroding. Txawm hais tias kub dip galvanized fasteners yuav corrode lub sij hawm raws li cov txheej hnav, lawv feem ntau zoo rau lub neej ntawm daim ntawv thov. Kub dip galvanized fasteners feem ntau yog siv rau sab nraum zoov daim ntaub ntawv uas lub fastener raug rau txhua hnub huab cua xws li los nag thiab daus. Cov cheeb tsam nyob ze ntawm ntug dej hiav txwv uas cov ntsev cov ntsiab lus hauv cov dej nag ntau dua, yuav tsum xav txog Stainless Steel fasteners raws li ntsev accelerates qhov deterioration ntawm galvanization thiab yuav ua rau kom corrosion.
Electro Galvanized (EG)
Electro Galvanized fasteners muaj txheej nyias ntawm Zinc uas muaj qee qhov kev tiv thaiv corrosion. Lawv feem ntau yog siv rau hauv thaj chaw uas xav tau kev tiv thaiv corrosion tsawg heev xws li chav dej, chav ua noj thiab lwm qhov chaw uas muaj kev cuam tshuam rau qee qhov dej lossis av noo. Cov ntsia hlau vov tsev yog electro galvanized vim lawv feem ntau hloov ua ntej lub fastener pib hnav thiab tsis raug rau huab cua hnyav yog tias ntsia tau zoo. Cov cheeb tsam ze ntawm ntug dej hiav txwv uas muaj ntsev hauv cov dej nag ntau dua yuav tsum xav txog Kub Dip Galvanized lossis Stainless Steel fastener.
Stainless hlau (SS)
Stainless hlau fasteners muab kev tiv thaiv corrosion zoo tshaj plaws muaj. Cov hlau yuav oxidize los yog xeb thaum lub sij hawm, tab sis nws yuav tsis poob nws lub zog los ntawm corrosion. Stainless hlau fasteners tuaj yeem siv rau sab nrauv lossis sab hauv thiab feem ntau tuaj hauv 304 lossis 316 stainless hlau.
