ASTM A36 / S235JR / Q235B Welded Rectangular Steel Yeeb Nkab

Welded Rectangular Hollow Section (RHS) yog qhov tseem ceeb profile dav siv hauv kev lag luam steel. Peb muab RHS hauv ASTM A36, S235JR thiab Q235B qib, suav nrog Asmeskas, European thiab Suav cov qauv kom tau raws li qhov yuav tsum tau ua ntawm cov haujlwm thoob ntiaj teb. Tsim los ntawm ERW siab- zaus kuj welding thiab nruam txias txoj kev ntawm steel sawb, peb cov kav dej muaj ib tug zoo li qub thiab ruaj khov weld seam. Nws yog tus nqi uas nyiam tshaj -cov qauv siv tau zoo rau kev tsim kho, kev tsim kho vaj tse, tshuab thiab xa tawm cov haujlwm.

Qib Taw Qhia

 

Q235B

Common Suav carbon structural steel nrog zoo cuam tshuam toughness rau ambient -kub yam ntxwv ua hauj lwm, ruaj khov thiab kev sib tw nqi.

S235 JR

Nrov tsis yog - alloy structural steel rau European lag luam. JR qib lav qhov ntsuas kub qhov cuam tshuam cov cuab yeej, dav lees paub hauv EU, Central Asia thiab Southeast Asia cov haujlwm.

ASTM A36 (ASTM txuj)

Mainstream carbon steel rau North America. Lub zog muaj zog ua kom tau raws li Asmeskas cov qauv kev tsim vaj tsev thiab cov khoom siv yooj yim hloov pauv rau Asmeskas & Canada kos duab.

Peb qib no muaj cov cuab yeej zoo sib xws thiab tuaj yeem hloov pauv tau rau feem ntau cov haujlwm, yooj yim rau kev sib tw thoob ntiaj teb thiab cov ntaub ntawv thaub qab.

◇ Pov thawj ERW vuam tshuab, txhim khu kev qha vuam zoo

Ua los ntawm kev nruam siab -frequency resistance welding. Sab nraud weld hlaws tshem tawm; sab hauv burr tuaj yeem txiav tau raws li qhov kev thov. Welds raug coj mus kuaj tsis yog -kev kuaj kev puas tsuaj (NDT). Tsawg distortion thiab nruj me ntsis kam rau ua raws li GB, EN thiab ASTM hollow seem qauv. Ntxuav txiav xaus tsis hnyav burrs, yooj yim rau txiav, drilling, khoov thiab sib dhos.

◇ Ntau qhov loj me & hloov tau kev pabcuam

Tag nrho ntau yam ntawm cov duab plaub, phab ntsa thickness ntawm 1.0mm txog 16mm. Standard ntev: 6m / 12m. Txiav-rau-ntev, beveling thiab ua ntej-drilling kev pabcuam muaj. Kev kho ntau yam saum npoo: dub tiav, kub-dip galvanized (GI), pleev xim rau, tiv thaiv- xeb roj, 3PE tiv thaiv- xeb txheej rau cov chaw ua haujlwm ntub lossis corrosive.

◇ Kev ua haujlwm zoo tshaj plaws & kev txuag nyiaj txiag

Rectangular hollow profile muab kev khoov zoo heev thiab torsional tsis kam. Raws li tib lub peev xwm thauj khoom, nws tus kheej - qhov hnyav yog qis dua li cov hlau tsis muaj zog, uas txo qis tag nrho cov qauv thauj khoom thiab cov nqi hauv paus. Ncaj thiab zoo zoo, zoo tagnrho rau cov thav duab raug thiab architectural steel decorations.

◇ Cov khoom ruaj khov & ua tiav cov ntaub ntawv xa tawm

Npaj khoom muaj; kev txiav txim loj tuaj yeem npaj rau kev tsim khoom sai. Mill Test Certificate (MTC) muab rau txhua batch nrog tag nrho cov tshuaj muaj pes tsawg leeg, tensile thiab cuam tshuam cov txiaj ntsig. Thib peb-kev soj ntsuam tog xws li SGS yog qhov lees txais. Peb tuaj yeem muab cov npe ntim khoom, daim ntawv them nqi lag luam, daim ntawv pov thawj ntawm lub hauv paus chiv keeb thiab lwm yam ntaub ntawv rau kev lis kev cai thoob ntiaj teb.

✅ Steel Rhiav & warehouse main thav duab, ru tsev thiab kem txhawb nqa

✅ Lub tsev ntaub thaiv phab ntsa keel, sab nrauv brackets, hniav steel ncej

✅ Choj theem ob cov qauv, kev txhawb nqa kev taug kev, guardrails thiab tsheb hlau ua haujlwm

✅ Thawv hauv paus, trailer ncej, machinery bases thiab khoom thav duab

✅ Tsev cog khoom thav duab, hnub ci brackets, cia racks thiab automated warehouse structures

✅ Cov khoom siv hauv paus, conveyor thav duab, laj kab ncej, kev txhawb nqa ib ntus

✅ Kev tsim kho vaj tse nyob txawv teb chaws thiab cov khoom siv hlau rau cov tshuab xa tawm

Cov ntaub ntawv raw khoom tau los ntawm kev tsim nyog steel mills nrog kev tshuaj xyuas tuaj. Ntau-theem hauv- kab tshuaj xyuas thaum tsim, vuam, ncaj, txiav thiab kos duab. Cov khoom tiav tsis muaj kab nrib pleb, delamination, indentations thiab hnyav xeb. Sampling mechanical and chemical tests tuaj yeem npaj tau raws li qhov yuav tsum tau ua kom ua tiav qhov kev lees paub hauv tsev thiab thoob ntiaj teb.
