(1) Cov tsos ntawm lub hnub ci racking: Muaj ntau txoj kev kho deg rau aluminium alloy profiles, xws li anodizing, tshuaj polishing, fluorocarbon spraying, electrophoretic txheej, thiab lwm yam.
Rau steel, kub-dip galvanizing, nto txau, xim txheej, thiab lwm yam. feem ntau yog siv. Cov tsos yog qhov phem tshaj qhov ntawm aluminium alloy profiles. Nws kuj tseem qis dua rau txhuas profiles hnub ci racking nyob rau hauv cov nqe lus ntawm corrosion kuj.
(2) Kev sib txawv ntawm ntu hnub ci racking: Cov txheej txheem ua haujlwm dav dav ntawm aluminium alloy profiles suav nrog extrusion, casting, dabtsi yog khoov, stamping, thiab lwm yam. Extrusion ntau lawm yog tam sim no mainstream ntau lawm txoj kev. Los ntawm kev qhib lub extrusion tuag, txhua ntu ntu profile tuaj yeem tsim tau, thiab cov khoom lag luam nrawm nrawm.
Cov ntaub ntawv hlau feem ntau siv txoj hauv kev xws li dov, casting, dabtsi yog khoov, thiab stamping. Tam sim no, dov yog txoj kev tsim khoom tseem ceeb rau kev tsim cov hlau txias. Cov ntu ntu yuav tsum tau hloov kho los ntawm cov txheej txheem rau cov menyuam, tab sis lub tshuab dav dav tsuas tuaj yeem tsim cov khoom zoo sib xws tom qab kev ua tiav, thiab qhov loj tuaj yeem hloov kho, thiab cov duab ntu tsis tuaj yeem hloov pauv, xws li C-shaped steel, Z- zoo li tus hlau thiab lwm yam ntoo khaub lig. Cov txheej txheem dov ntau lawm yog qhov ruaj khov thiab cov khoom lag luam nrawm nrawm.
