Cov khoom siv feem ntau siv hauv cov ntawv hlau ua yog txias- cov ntawv dov (SPCC), kub- cov ntawv dov (SHCC), galvanized ntawv (SECC, SGCC), tooj liab (CU) tooj dag, tooj liab liab, beryllium tooj liab, txhuas ntawv (6061, 5052, 1010, 1060, 6063, duralumin, thiab lwm yam), stainless hlau (daim iav nto, txhuam nto, matte nto), raws li qhov sib txawv ntawm cov khoom, cov khoom sib txawv raug xaiv, feem ntau yuav tsum xav txog kev siv thiab tus nqi ntawm cov khoom.
1. Txias- dov daim ntawv SPCC, feem ntau yog siv rau electroplating thiab ci xim, tus nqi qis, yooj yim rau daim ntawv, cov khoom thickness tsawg dua los yog sib npaug li 3.2 hli.
2. Kub- dov daim ntawv SHCC, cov khoom siv T loj dua los yog sib npaug rau 3.0mm, kuj siv electroplating, xim qhov chaw, tus nqi qis, tab sis nyuaj rau kev tsim, feem ntau yog cov tiaj tiaj.
3. Galvanized ntawv SECC, SGCC. SECC electrolytic phaj muab faib ua N khoom thiab P khoom. N cov khoom siv feem ntau yog siv rau kev kho deg, uas yog kim, thiab cov khoom siv P yog siv rau cov khoom txau.
4. tooj liab; Feem ntau yog siv rau cov khoom siv hluav taws xob, thiab nws qhov kev kho saum npoo yog npib tsib xee-plated, chrome-plated, lossis tsis kho, thiab tus nqi siab.
5. Aluminium phaj; feem ntau siv deg chromate (J11-A), oxidation (conductive oxidation, tshuaj oxidation), tus nqi siab, nyiaj plating, npib tsib xee plating.
6. Aluminium profiles; cov ntaub ntawv nrog cov ntoo khaub lig-sectional structures, uas yog dav siv nyob rau hauv ntau yam sub-boxes. Kev kho saum npoo yog tib yam li cov phaj txhuas.
7. Stainless steel; mainly used without any surface treatment, high cost.
