Muaj ntau ntau cov qauv thoob ntiaj teb thiab lub teb chaws uas tswj hwm kev tsim khoom thiab kev ua haujlwm zoo ntawm cov raj hlau square. Ib qho kev pom zoo tshaj plaws yog ASTM (American Society for Testing and Materials) tus qauv. ASTM A500, piv txwv li, qhia txog qhov yuav tsum tau ua rau txias - tsim welded thiab seamless carbon steel structural tubing nyob rau hauv round, square, thiab rectangular duab. Nws npog ntau yam xws li tshuaj muaj pes tsawg leeg, txhua yam khoom, qhov ntev, thiab kam rau ua
- ASTM A500 (Tebchaws Asmeskas): Txheem specification rau txias-tsim welded carbon steel structural tubing.
- EN 10219 (Tebchaws Europe): Cold-formed welded structural hollow seem ntawm non-alloy thiab fine-grain steels.
- JIS G 3463 (Nyiv): Cov pa roj carbon steel lub raj raj rau kev ua haujlwm dav dav.
- GB / T 6728 (Tuam Tshoj): Cold-formed welded steel hollow seem rau kev siv.


Rectangular steel raj yog siv nyob rau hauv ntau yam lag luam, xws li:
Kev tsim kho: Lub tsev thav duab, ru tsev trusses, kab, thiab kev txhawb nqa.
Automotive & Machinery: Chassis, yob tawb, thiab cov khoom siv.
Infrastructure: choj, guardrails, thiab signboard txhawb.
Furniture & Architecture: Niaj hnub nimno rooj tog, tes tuav, thiab cov qauv zoo nkauj.
Cov cuab yeej siv: Conveyor systems, cia racks, thiab scaffolding.
Xaus
Rectangular steel tubes muab kev ua haujlwm zoo tshaj plaws, muaj peev xwm ua tau zoo, thiab tus nqi ua haujlwm, ua rau lawv nyiam xaiv hauv engineering thiab kev tsim kho. Ua raws li cov qauv thoob ntiaj teb ua kom muaj kev ntseeg siab thoob plaws qhov sib txawv
