Feem ntau specifications rau square tubes

Square thiab Rectangular Tubes, ib lub sij hawm rau square square raj, uas yog steel hlab nrog sib npaug thiab tsis sib npaug sab ntev. Nws yog ib lub strip ntawm steel dov tom qab ib tug txheej txheem. Feem ntau, cov sawb hlau yog unwrapped, flattened, curled, welded los tsim ib puag ncig lub raj, thiab ces dov los ntawm lub round raj mus rau hauv ib lub raj square thiab ces txiav mus rau qhov yuav tsum tau ntev.Lub steel yeeb nkab nrog sib npaug sab ntev yog hu ua square yeeb nkab, code F. Cov yeeb nkab steel uas tsis sib npaug sab ntev yog hu ua square yeeb nkab, code J.
