Lub kaum hlau yog ib txoj hlua ntev ntawm cov hlau nrog ob sab perpendicular rau ib leeg. Muaj lub kaum sab xis steel thiab lub kaum sab xis tsis sib xws. Qhov dav ntawm ob sab ntawm lub kaum sab xis steel yog sib npaug. Nws specifications qhia nyob rau hauv millimeters ntawm sab dav × sab dav × sab thickness. Piv txwv li, "∟30 × 30 × 3" txhais tau hais tias lub kaum sab xis steel nrog ib sab dav ntawm 30 hli thiab sab tuab ntawm 3 hli. Nws kuj tseem tuaj yeem qhia los ntawm tus qauv naj npawb, uas yog tus lej ntawm centimeters ntawm sab dav, xws li ∟3 #. Tus qauv naj npawb tsis qhia qhov ntev ntawm qhov sib txawv ntawm cov thicknesses hauv tib tus qauv. Yog li ntawd, sab dav thiab sab thickness qhov ntev ntawm lub kaum sab xis steel yuav tsum tau sau tag nrho ntawm daim ntawv cog lus thiab lwm cov ntaub ntawv kom tsis txhob siv tus qauv tooj ib leeg. Cov specifications ntawm kub dov equilateral lub kaum sab xis steel yog 2 # -20#.
Lub kaum sab xis steel tuaj yeem tsim los ntawm ntau yam kev ntxhov siab-kev coj tus kheej raws li qhov xav tau sib txawv ntawm cov qauv, thiab tuaj yeem siv los ua qhov sib txuas ntawm cov khoom. Nws yog dav siv nyob rau hauv ntau lub tsev tsim thiab engineering, xws li ru tsev kab teeb, txuas hniav, kis tau tus mob yees, nqa thiab tsheb thauj mus los machinery, ships, industrial furnaces, tshuaj tiv thaiv yees, thawv racks thiab warehouses.
Nws feem ntau muab faib ua ob hom: lub kaum sab xis steel thiab lub kaum sab tsis sib npaug. Ntawm lawv, lub kaum sab xis hlau tsis sib npaug tuaj yeem muab faib ua ob hom: tsis sib xws sab thiab sib npaug thickness thiab tsis sib npaug sab thiab tsis sib xws.
Cov specifications ntawm lub kaum sab xis steel yog qhia los ntawm qhov ntev ntawm sab ntev thiab sab thickness. Lub kaum sab xis steel specifications nyob ntawm No. 2 mus rau No. 20, nrog rau tus naj npawb hauv centimeters ntawm sab ntev yog tus lej. Tib lub kaum sab xis steel feem ntau muaj 2 txog 7 qhov sib txawv sab tuab. Imported lub kaum sab xis qhia txog qhov loj thiab tuab ntawm ob sab thiab cov qauv tsim. Feem ntau, cov uas muaj ib sab ntev ntawm ntau tshaj 12.5cm yog lub kaum sab xis loj, cov uas muaj ib sab ntev ntawm 12.5cm thiab 5cm yog nruab nrab lub kaum sab xis steels, thiab cov uas muaj ib sab ntev ntawm tsawg dua 5cm yog lub kaum sab xis me me.
