Gnee muaj S355m H-Beams hauv ntau qhov ntau thiab tsawg, txhua qhov qauv thiab customizable raws li kev thov. Cov Flange ntawm H-Beam yog dav dua li lub vev xaib, muab cov khoom noj tau zoo heev thiab ruaj khov. Feem ntau qhov sib npaug suav nrog qhov siab, Flange dav thiab Web Thickness.

S355m steel tuaj yeem yooj yim welded siv txhua txoj kev sib tw vuam. Kev ua ntej yuav tsum muaj rau cov ntu tuab lossis qhov uas muaj kev pheej hmoo ntawm hydrogen cracking. Tsis tas li ntawd, S355M H-Beams tuaj yeem pleev xim lossis galvanized los tiv thaiv corrosion. Lwm txoj kev kho nyob ib yam li kev txhaj tshuaj peenate lossis cov chaw ua haujlwm tseem tuaj yeem siv tau.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
