ASTM A500 Qib A RHS vs B RHS
A500 specification npog txias - tsim welded thiab seamless carbon steel structural raj ntawm puag ncig, square, rectangular, los yog tshwj xeeb cov duab siv rau vuam, kho, los yog load- bearing nyob rau hauv cov choj, vaj tse, thiab cov qauv.
Welded los yog seamless raj tsim raws li qhov kev qhia tshwj xeeb no yuav tsum tsis txhob muaj qhov dav dav tshaj 64 ntiv tes (1626 hli) thiab phab ntsa tuab tsis tshaj 15.88 hli.
