Q235 Q355 Lub kaum ntse ntse hlau

Q235 yog ib qho yooj yim carbon structural steel uas yog siv thoob plaws hauv Suav teb. Nws tseem hu ua Q235A, Q235B, Q235C, thiab Q235D. Txij li nws yog cov hlau me me, nws yog siv hauv kev tsim khoom yam tsis muaj kev kho cua sov. Q qhia qhov taw tes tawm los, thiab 235 qhia tias lub zog tawm los. Nws muaj cov yas zoo thiab weldability.Q355 steel yog cov hlau tsis tshua muaj hlau, muaj zog hlau uas siv rau hauv cov qauv welded txhawb kev ntxhov siab thiab hnyav hnyav. Q hais txog qhov taw tes tawm los, thaum tus lej 355 qhia nws lub zog tawm los. Nws kuj hloov Q345.

Qhov zoo ntawm kev siv Angle Bar

Angle Bars feem ntau yog siv rau ntau yam kev tsim kho vim yog cov txiaj ntsig hauv qab no:

Ntau yam

Lub kaum sab xis tuaj yeem ua tau yooj yim drilled, bolted, welded, lossis trimmed kom haum rau txhua qhov kev tsim kho. Lawv muaj txiaj ntsig zoo hauv ntau daim ntawv thov, xws li thav duab, kev txhawb nqa, bracing, thiab trusses.

Kev txhawb nqa tus qauv

Lub kaum sab xis 'L-shaped tsim ua rau nws zoo tagnrho rau kev txhawb nqa thiab kev ruaj ntseg. Lawv muab rigidity thiab khoov tsis kam rau cov qauv.

Aesthetic thov

Lub kaum sab xis muab qhov zoo nkauj txaus siab rau kev tsim vaj tsev ntxiv rau lawv cov txiaj ntsig kev tsim kho. Lawv tuaj yeem siv los ua cov khoom zoo nkauj, trimmings, lossis thav duab uas txhim kho qhov zoo nkauj tag nrho ntawm cov qauv.

Load bearing muaj peev xwm

Lub kaum sab xis muaj peev xwm thauj khoom zoo heev vim lawv daim ntawv. L-shaped cross-section faib qhov hnyav sib npaug ntawm ob txhais ceg, tso cai rau lawv dais loj thiab muab kev ruaj ntseg.
