C-channel steel, tseem hu ua channel steel, feem ntau yog ua los ntawm cov hlau me me lossis me me. Cov hlau me me yog cov hlau uas muaj cov pa roj carbon tsawg, feem ntau tsawg dua 0.25% los ntawm qhov hnyav. Qhov no ua rau nws yooj yim dua rau kev siv, vuam thiab daim ntawv, ua rau nws haum rau ntau yam kev siv hauv tsev thiab cov qauv siv.
Kev siv cov pa roj carbon tsawg hauv C-channel kev tsim kho muab qhov sib npaug ntawm lub zog, weldability thiab tus nqi zoo. Cov pa roj carbon tsawg yog nkag tau yooj yim, pheej yig, thiab tuaj yeem tsim nrog cov khoom sib xws, ua rau nws muaj kev xaiv rau cov khoom siv xws li C-channels.
Thaum cov hlau me me yog cov khoom siv feem ntau siv rau C-channel steel, lwm hom hlau lossis hlau alloys tuaj yeem siv rau cov ntawv tshwj xeeb uas xav tau lub zog siab dua lossis cov khoom tshwj xeeb.
