Cov qauv steel siv rau kev txhawb nqa brackets siv ntau hom hlau, feem ntau suav nrog carbon steel thiab alloy steel. Cov ntaub ntawv no muaj lub zog siab thiab zoo heev plasticity, ua rau lawv tiv taus qhov hnyav thiab kev ntxhov siab. Tsis tas li ntawd, steel exhibits zoo weldability thiab toughness, ua rau nws yooj yim rau txheej txheem thiab nruab.
Carbon steel qauv
Carbon structural steel yog ib qho ntawm cov khoom siv feem ntau siv rau kev txhawb nqa steel. Nws muaj lub zog zoo heev, toughness, thiab weldability, ua kom nws tiv taus qhov hnyav thiab kev ntxhov siab. Cov qhab nia muaj xws li Q235 thiab Q345; Q345 muaj lub zog ntau dua thiab tsim nyog rau kev txhawb nqa kom muaj peev xwm ntau dua -cov kabmob.
Tsawg-High Alloy-Strength Steel
Txhawm rau txhim kho ob qho tib si thauj khoom -cov kabmob muaj peev xwm thiab kev tiv thaiv corrosion, qee qhov kev txhawb nqa steel siv qis- alloy siab- lub zog steels, xws li Q390 thiab Q420. Thaum tuav cov khoom siv kho tshuab zoo heev, cov hlau no sib dua hauv qhov hnyav dua -pab kev tsim kho thiab kev teeb tsa- thiab muab cov huab cua tiv thaiv zoo tshaj plaws hauv qhov chaw sab nraum zoov.
Anti-Cov khoom siv kho corrosion
Steel structural kev txhawb nqa feem ntau tau txais kev tiv thaiv saum npoo kom ntev lawv lub neej kev pab. Cov txheej txheem muaj xws li kub-dip galvanizing, nrog rau kev siv cov xim epoxy lossis polyester txheej. Cov kev kho mob no tiv thaiv xeb thiab xeb, ua rau lawv tshwj xeeb tshaj yog haum rau kev txhawb nqa nyob rau sab nraum zoov lossis qhov chaw ntub dej.
