S355K2H structural hollow profiles yog cov khoom lag luam raws li EN 10210-1 tus qauv thiab yog ib feem ntawm cov txheej txheem kub dov steel leeg ntawm non-alloy thiab nplua-grained steel. Nrog zoo toughness thiab weldability, nws yog tshwj xeeb tshaj yog haum rau cov qauv siv uas yuav tsum tau muaj zog thiab zoo toughness. Cov khoom siv no tsuas yog siv hauv engineering xws li kev tsim kho thiab offshore platforms.
EN 10210-1 S355K2H structural hollow raj muaj ntau yam specifications, xws li puag ncig, square, rectangular thiab oval, thiab tuaj yeem hloov kho ntau qhov sib txawv thiab cov duab raws li kev thov tshwj xeeb. Tsis tas li ntawd, nws tseem tuaj yeem tsim cov raj steel nrog cov phab ntsa sib txawv raws li qhov xav tau kom ua tau raws li qhov xav tau ntawm cov kabmob sib txawv.
