Lub raj plaub yog lub cev square-puab ntawm cov yeeb nkab, tseem hu ua steel tub yees khoov profile, txias-drawn los yog nias-dov txhuas nyias-walled steel yeeb nkab.Rectangular raj specifications qhia nyob rau hauv cov nqe lus ntawm sab ntev thiab phab ntsa thickness rauwelded steel tubes, tseem hu ua welded raj;seamless steel raj yog tsim los ntawm ingots los yog khoom billets uas yog perforated los ua ib tug burr raj thiab ces kub dov, txias dov los yog txias dialed.

Galvanized square tubeyog ib lub npe rau cov yeeb nkab square thiab ib lub npe rau cov yeeb nkab galvanized, uas yog raws li q195, q215, lossis ss400.Nws yog tsuas yog siv nyob rau hauv kev tsim kho kev lag luam rau curtain phab ntsa, steel qauv, thiab mesh thav duab tej yaam num.

Yog li dab tsi yog lub luag haujlwm ntawm galvanized square raj?Dab tsi yog lub luag haujlwm ntawm galvanized square raj.

1 、 Nws yog siv rau ntau yam khoom siv hlau, cov ntawv hlau hauv kev tsim tsheb.

2, Nws tuaj yeem siv rau stamping qhov chaw hauv kev ua tshuab.

3 、 Nws tuaj yeem siv los ua cov paj ntoo zoo nkauj thiab rooj tog.

4 、 Nws tuaj yeem siv rau tsheb kauj vab handlebars, pib qhov chaw, thiab lwm yam.

5 、 Nws tuaj yeem siv rau ntau cov kav hlau steel rau cov pob txha ntawm lub tsev cog khoom thiab cov tsiaj txhu sov so hauv kev ua liaj ua teb.

6 、 Nws tuaj yeem siv los ua ntau yam kev tiv thaiv cov kav dej hauv offshore roj drilling platform thiab nkoj kev lag luam nrog rau cov khoom siv welded hauv kev tsim cov qauv steel.

7 、 Nws kuj tseem siv tau los ua cov kav dej steel rau cov dej ntws ntawm cov tshuab ua liaj ua teb.

8 、 Siv dav hauv kev tsim khoom lag luam xws li tsheb qhov chaw, khoom siv hauv tsev, thiab lwm yam.

9, Feem ntau yog siv rau hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog nyob rau hauv high-rise civil vaj tse, steel qauv ncej erection (tseem hu ua "piling") yog ua los ntawm kub dipped galvanized steel yeeb nkab ncej txaj.

10, vim tias qhov kub dip txheej txheej yog nqa tawm sab nraum zoov, yooj yim rau corroded los yog xeb!Yog li ntau tus neeg muas zaub xaiv txias-draw los yog txias-dov hlau!

11 、 Kev siv dav davseamless steel yeeb nkabmanufacturing txheej txheem los tsim.
