Hollow structural hlau (HSS)tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov duab kom tau raws li qhov yuav tsum tau muaj ntawm cov txheej txheem sib txawv thiab kev siv engineering. Qhov loj ntawm HSS feem ntau yog teev los ntawm nws qhov ntev, suav nrog qhov dav dav, sab nrauv qhov siab, thiab phab ntsa thickness. Cov duab zoo sib xws rau HSS muaj xws li square, rectangular, thiab ncig. Nov yog qee qhov piv txwv ntawm HSS qhov ntau thiab tsawg:
Square HSS:Qhov ntau thiab tsawg HSS muaj xws li 2x2 ntiv tes, 3x3 ntiv tes, 4x4 ntiv tes, 6x6 ntiv tes, thiab 8x8 ntiv tes. Qhov ntev yog feem ntau muab hauv ntiv tes, tab sis lawv tuaj yeem teev nyob rau hauv millimeters.
Rectangular HSS:Qhov ntau thiab tsawg HSS muaj xws li 2x3 ntiv tes, 2x4 ntiv tes, 3x4 ntiv tes, 4x6 ntiv tes, thiab 8x10 ntiv tes. Cov qhov ntev no tau muab rau hauv nti, tab sis lawv tuaj yeem teev nyob rau hauv millimeters.
Circular HSS:Circular HSS qhov ntau thiab tsawg yog feem ntau teev los ntawm lawv txoj kab uas hla. Qhov ntau thiab tsawg tuaj yeem suav nrog 1 nti, 2 nti, 4 nti, 6 nti, thiab 8 nti. Qhov ntev yog feem ntau muab hauv ntiv tes, tab sis lawv tuaj yeem teev nyob rau hauv millimeters.
Phab ntsa tuab ntawm HSS kuj tuaj yeem sib txawv, thiab nws feem ntau teev nrog rau qhov ntev. Piv txwv li, tej zaum koj yuav pom HSS piav raws li "2x2 ntiv tes nrog 1/8-inch phab ntsa tuab."
