Cov yeeb nkab steel hlau tau muab faib ua cov pa roj carbon zoo tib yam, cov yeeb nkab zoo carbon steel yeeb nkab, cov yeeb nkab steel hlau, cov yeeb nkab steel hlau, cov yeeb nkab steel, cov yeeb nkab steel hlau, thiab cov kav dej bimetallic composite kav, plated thiab coated kav kom txuag tau cov hlau tseem ceeb thiab ua tau raws cov cai tshwj xeeb..
Raws li txoj kev tsim khoom, nws tau muab faib ua ob pawg: seamless kav thiab welded kav.Seamless steel kav tuaj yeem muab faib ua cov kav dej kub, cov kav dej txias, cov kav dej txias thiab cov kav dej extruded.Cold-draw thiab txias-dov yeeb nkab yog cov txheej txheem thib ob ntawm cov kav dej steel;Cov kav dej welded tau muab faib ua ncaj seam welded kav thiab kauv welded kav.
Raws li tus ntoo khaub lig-sectional duab, nws tuaj yeem muab faib ua cov raj puag ncig thiab lub raj tshwj xeeb.Cov hlab ntsha tshwj xeeb muaj xws li cov hlab ntsha, cov hlab ntsha pob zeb diamond, elliptical leeg, hexagonal hlab, octagonal leeg, thiab ntau yam asymmetrical leeg.
