ASTM A252 Qib 2 ERW Steel Yeeb Nkab yog ib qho welded steel yeeb nkab tsim raws li ASTM A252 tus qauv specification, tsim tshwj xeeb rau piling thiab sib sib zog nqus hauv paus daim ntaub ntawv. Ua los ntawm Electric Resistance Vuam (ERW) txheej txheem, nws ua hauj lwm raws li ib tug mus tas li load- nqa structural tswv cuab los yog ib lub plhaub rau cam khwb cia- nyob rau hauv - qhov chaw pob zeb.
Nrog rau cov khoom sib npaug, weldability zoo heev, thiab tus nqi -kev ua tau zoo, ASTM A252 Qib 2 yog qib feem ntau tau teev tseg rau feem ntau mus rau nruab nrab -load-cov ntaub ntawv siv cov kabmob xws li choj hauv paus, kev txhawb nqa lub tsev, thiab cov kav dej hiav txwv.
