Dab tsi yog carbon steel square tube
Carbon Steel Square Tube (Carbon Steel Square Hollow Section / SHS / Steel Box Tshooj / Mild Steel Square Pipe)yog lub siab -lub zog steel profile dav siv nyob rau hauv kev tsim kho, engineering, thiab industrial fabrication. Ua los ntawm premium-qib carbon steel xws liQ235, Q345, ASTM A500 Qib B / C, nws muaj cov weldability zoo heev, machinability, thiab load- bearing kev ua tau zoo rau ob qho tib si lub teeb thiab hnyav - lub luag haujlwm daim ntawv thov.
Muaj nyob rau hauv ntau yam ntawmtxheem thiab customized ntau thiab tsawg los ntawm 20 × 20mm mus rau 200 × 200mm, nrog phab ntsa thickness xaiv los ntawm1.2mm txog 12mm, carbon steel square tubes yog tsim nyob rau hauv raws li thoob ntiaj teb cov qauv xws liASTM A500, EN 10219, thiab GB / T 6728. Surface finishes suav nrogdub steel, kub-dip galvanized, ua ntej-galvanized, thiab tiv thaiv-corrosion coated, ua kom lub neej ntev kev pab cuam txawm nyob rau hauv ib puag ncig hnyav.
Raws li cov khoom siv ntau yam, Carbon Steel Square Tube tseem hu uaSHS steel tube, square hollow seem steel, structural steel square tubing, carbon steel kem seem, thiab me me steel hollow square yeeb nkab. Nws yog dav siv nyob rau hauvsteel tsev thav duab, warehouse structures, txuas hniav, machinery fabrication, conveyor systems, automotive Cheebtsam, hnub ci mounting systems, thiab architectural moj khaum.
Nrog nws kev sib xyawsiab zog, nqi efficiency, qhov tseeb, thiab thoob ntiaj teb tus qauv ua raws, carbon steel square tubing yog ib qho ntawm cov kev xav tau tshaj plaws steel profiles hauv ntiaj teb engineering thiab kev tsim kho kev lag luam.
