Lub kaum sab xis steel Q345 Q235 SS400 kub dov galvanized

Nyob rau hauv lub tshav pob ntawm engineering cov ntaub ntawv, lub kaum sab xis steel yog muab faib ua ob hom: sib npaug lub kaum sab xis steel thiab tsis sib npaug lub kaum sab xis. Qhov tshwj xeeb ntawm lub kaum sab xis tsis sib xws yog qhia los ntawm qhov ntev ntawm sab ntev thiab sab tuab. Hais txog steel nrog angular cross-section thiab tsis sib npaug ntawm ob sab. Nws yog hom kaum steel. Rolled los ntawm ib tug kub dov zeb. Piv nrog rau ob lub kaum sab xis steels nrog qhov sib npaug ntawm sab ntev, nws hais txog lub kaum sab xis ntawm pej xeem nrog rau txoj cai-lub kaum sab xis L-shaped hla ntu thiab qhov ntev tsis sib npaug ntawm ob sab. Vim tias nws cov khoom noj tsawg dua ib sab ntawm lub kaum sab xis steel, tus nqi txheeb ze dua me ntsis.
