1. Cov ntsiab lus sib txawv: C-shaped steel yog tsim los ntawm txias-bending kub coil phaj. Nws muaj cov phab ntsa nyias nyias thiab lub teeb yuag, kev ua haujlwm zoo heev ntawm cov ntu ntu thiab lub zog siab. Piv nrog cov tsoos channel steel, tib lub zog tuaj yeem txuag tau li 30% ntawm cov ntaub ntawv. Channel steel yog tsim los ntawm kub dov thiab muab ncaj qha los ntawm steel mills. Nws yog cov khoom siv hlau ntev nrog lub thickness loj thiab qhov zawj-zoo li tus ntoo khaub lig-section.
2. Kev faib tawm txawv: C-shaped steel tuaj yeem muab faib ua galvanized C-shaped steel, kub-dip galvanized cable tais C-shaped steel, tsis sib xws C-shaped steel, tsheb profile C-shaped steel, thiab lwm yam, thaum channel steel tuaj yeem Tsuas yog muab faib ua: zoo tib yam channel steel thiab Lub teeb channel steel.
3. Kev siv sib txawv: Tshooj steel muaj ntau yam tshwj xeeb ntawm kev siv. Nws yog tsuas yog siv rau purlins thiab phab ntsa beams nyob rau hauv steel qauv vaj tse. Nws tseem tuaj yeem sib sau ua ke rau hauv lub ru tsev trusses, brackets thiab lwm yam khoom siv hauv tsev. Channel steel yog tsuas yog siv nyob rau hauv lub tsev tsim, tsheb tsim thiab lwm yam kev lag luam qauv. Channel steel feem ntau yog siv ua ke nrog I-beams. Txawm hais tias ob qho tib si tuaj yeem siv hauv kev tsim kho kev lag luam, lawv cov kev siv tseem txawv.
