1. ASTM A36 Dav Dav Flange Beams
Ua tus qauv carbon steel, ASTM A36 muaj weldability zoo thiab tsim nyog tus nqi. Hom hlau no zoo meej rau kev siv dav dav hauv kev tsim kho, thiab nws tsis tas yuav tsum muaj zog tshwj xeeb. A36 yog cov khoom siv dav dav rauH beams 150 x 150thiabH beams 300 x 300thiab lwm yam vim nws yooj yim rau kub dov thiab ntau yam.
2. ASTM A572-50 Dav Dav Flange Beams
Cov hlau no muaj zog heev thiab tsis tshua muaj hlau sib xyaw yog cov hlau uas sib npaug rau A36 carbon steel thiab muaj zog dua uas ua rau nws tsim nyog siv rau ntau daim ntawv thov, xws li kev tsim kho choj lossis tsev ntau txheej. Astm A572-50 cov kab hlau dav dav yog qhov zoo tshaj plaws rau kev tsim kho choj thiab hauv cov tsev siab. Lub zog zoo ua ke nrog kev tawv zoo los muab tus cwj pwm zoo dua hauv qab kev thauj khoom.
3. ASTM A992 Dav Dav Flange Beams
ASTM A992 cov kab hlau dav dav tam sim no yog kev tsim kho vaj tse organic hauv North America, uas yog qhov tsim nyog rau cov qauv hlau. Muab qhov sib piv ntawm lub zog-rau-qhov hnyav dua, weldability zoo thiab kev tiv taus siab dua rau kev khoov, A992 beams tau pom lawv qhov chaw hauv ntau cov qauv niaj hnub. Txawm hais tias koj yuav cov hlau kub dov H beam lossisQhov Loj ntawm H Beamlos yog xav tau tshwj xeebQhov ntev ntawm H Beam, Qhov zoo ntawm A992 yog qhov txhim khu kev qha.
