Hollow Structural Steel

Square thiab rectangular tubing tseem hu ua HSS (hollow structural steel).

Square thiab rectangular tubing yeej ib txwm hu tawm tib txoj kev. Thawj ob tus lej xaiv qhov loj ntawm cov khoom (hauv ntiv tes). Tus lej kawg (feem ntau yog suav tias yog tus lej lej) txhais lub thickness ntawm lub raj. Ib qho piv txwv hu rau cov qauv duab plaub yuav yog TS 8 "x 6" x .375". Koj paub qhov no yog lub raj raj vim tias ob sab tsis sib npaug.

khoov square thiab duab plaub (HSS) rau ntau qhov laj thawj. Thaum peb yob khoov HSS peb feem ntau sau cov khoom nrog mandrels, qhov twg peb tig cov khoom hollow rau hauv cov khoom. Qhov no yuav pab txo qis distortion yam tsis tau nce lub thickness ntawm cov khoom. Tsis tas li ntawd thaum yob dabtsi yog khoov peb siv cov kev cai ua lub vojvoog kaum qhov cuab yeej kom phim lub vojvoog kaum ntawm qhov sib txawv ntawm cov khoom siv HSS. Qhov kev sib tw ntawm cov cuab yeej thiab cov khoom no ua rau muaj kev khoov zoo dua. Thaum peb khoov stringers rau kauv staircases peb tsis sau cov ntaub ntawv HSS nrog cov tswv cuab ruaj khov los tswj kev cuam tshuam. Hloov chaw, peb tau tsim txoj hauv kev los khoov kub los yog induction khoov HSS cov ntaub ntawv mus rau ib qho kev teeb tsa uas tsis muaj qhov khoob ntawm cov khoom siv. Cov txheej txheem tshwj xeeb no tso cai rau peb cov neeg siv khoom siv HSS stringers rau lawv cov staircases yam tsis muaj qhov hnyav ntxiv lossis tsis yooj yim ntawm cov ntaub ntawv muab tub lim.

Carbon square thiab rectangular cov ntaub ntawv (zeb tsim) yog cais raws li ASTM A500 uas ua rau ib tug yield point (psi) ntawm 39, 000 yam tsawg kawg nkaus rau Qib A thiab 46, 000 yam tsawg kawg nkaus rau Qib B.

Peb khoov tag nrho cov khoom ntev nrog rau cov khoom tsis ntev. Cov khoom ntev tuaj luv li 20 ko taw thiab tom qab ntawd tuaj hauv ntau txoj kev xaiv txog 60 ko taw ntev.

Cov ntaub ntawv square thiab Rectangular tuaj yeem siv rau hauv txhua daim ntawv thov. Cov qauv (ru tsev trusses), ornamental (staircases), kev ua si (tsheb kauj vab racks), kev tsim khoom (ntau yam widget) thiab kos duab. Zoo, txhua yam uas yuav tsum tau khoov, tuaj yeem ua tau, thiab tsim tawm ntawm cov ntaub ntawv square thiab rectangular (HSS cov ntaub ntawv).
