Structural steel yog ib qeb ntawm cov hlau siv los ua cov khoom siv los ua cov qauv steel duab.Cov qauv steel qauv yog ib qho profile, tsim nrog ib qho kev hla ntu thiab ua raws qee cov qauv rau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.Cov qauv steel duab, qhov ntau thiab tsawg, muaj pes tsawg leeg, muaj zog, kev coj ua, thiab lwm yam, yog tswj hwm los ntawm cov qauv hauv ntau lub teb chaws industrialized.

Cov tswv cuab ntawm cov qauv hlau, xws li I-beams, muaj lub sijhawm siab thib ob ntawm thaj chaw, uas tso cai rau lawv kom nruj heev rau lawv qhov chaw hla ntu.

Cov qauv zoo sib xws

Cov duab uas muaj tau piav qhia nyob rau hauv ntau cov qauv luam tawm thoob ntiaj teb, thiab muaj ntau tus kws tshaj lij thiab cov khoom hla ntu tseem muaj.

·I-beam (I-shaped cross-section - hauv teb chaws Aas Kiv cov no suav nrog Universal Beams (UB) thiab Universal Columns (UC); hauv Europe nws suav nrog IPE, HE, HL, HD thiab lwm ntu; hauv Asmeskas nws suav nrog Wide Flange (WF lossis W-Shape) thiab H seem)

·Z-Shape (ib nrab ntawm flange nyob rau hauv opposite lus qhia)

·HSS-Shape (Hollow structural seem tseem hu ua SHS (cov qauv hollow seem) thiab suav nrog square, rectangular, ncig (pipe) thiab elliptical hla ntu)

·Lub kaum sab xis (L-shaped cross-section)

·Tus qauv channel, los yog C-beam, los yog C cross-section

·Tee (T-shaped cross-section)

·Rail profile (asymmetrical I-beam)

·Txoj kev tsheb ciav hlau

·Vignoles rail

·Flanged T rail

·Grooved rail

·Bar, ib daim hlau, cov duab plaub hla ntu (pas) thiab ntev, tab sis tsis dav thiaj li hu ua daim ntawv.

·Qws, ib puag ncig los yog square thiab ntev daim hlau, saib kuj rebar thiab dowel.

·Phaj, hlau ntawv tuab dua 6 hli los yog 1⁄4in ib.

·Qhib web steel joist

Txawm hais tias ntau ntu yog ua los ntawm kub lossis txias dov, lwm tus yog ua los ntawm kev sib txuas ua ke nrog cov pav ca los yog khoov daim hlau (piv txwv li, cov seem loj tshaj plaws yog tsim los ntawm cov phaj tiaj tiaj khoov rau hauv lub voj voog thiab seam-welded).
