Q: Dab tsi yog qhov txawv ntawm Astm A36 thiab Q235b hauv cov txheej txheem ntawm cov hlau hlau rau h} Beams, tab sis lawv ua raws cov qauv hauv cheeb tsam sib txawv thiab muaj lub zog sib txawv. ASTM A36 yog ib qib Asmeskas tus qauv nrog tsawg kawg ntawm 400-550 MPa thiab tensile cov phiaj xwm rau nws lub zog sib luag thiab weldability. Q235B yog tus qauv Suav theem (GB / T 700) nrog rau 235 MPA tsawg kawg lub zog, Nrov hauv Asian Callets rau tus nqi- ua hauj lwm zoo. Ob qho tib si yog tsim nyog rau tsim cov nyom welded, tab sis Astm A36 muaj me ntsis rau siab dua, ua rau nws zoo dua rau kev lag luam zoo li kev lag luam thav ntawv. Q235B ua haujlwm zoo rau cov ntawv thov sib zog xws li kev txhawb nqa nyob hauv tsev. Rau cov neeg yuav khoom, qhov kev xaiv feem ntau nyob ntawm qhov chaw ua haujlwm (los kho kom haum rau weld thiab daim ntawv, ua kom muaj kev sib haum xeeb nrog koj cov qauv.

3. Kev Ua Yeeb Yam & Kev Nug Cov Lus Nug
Q: Dab tsi thauj khoom tuaj yeem ua cov ovtm A36 h {} Beads muaj peev xwm ua kom muaj kev cia siab welded? A: For example, a 200mm-deep ASTM A36 H-beam (flange width 100mm, web thickness 6mm) can safely support a uniformly distributed load of ~15 kN/m over a 6-meter span-enough for residential floor joists or small commercial mezzanines. Tshaj ib 4 {{- 'meter', nws lub peev xwm nce mus rau ~ 33 kn / m, haum rau hnyav siv zoo li kev lag luam welving. Cov tsim muaj welded tsim cov welds ua kom cov nqaj tsis swb ntawm lub vev xaib web-flange, txawm tias muaj kev ntxhov siab. Load muaj peev xwm tseem nyob ntawm kev teeb tsa: Beams yuav tsum tau muab tso nrog Flanges kab rov tav kom ua qhov ua tau zoo heev. Cov kws ua haujlwm ua rau cov kws ua haujlwm feem ntau ntxiv ib qho 1.5-2.2 qhov kev nyab xeeb rau cov naj npawb no rau tus account rau kev npaj txhij txog thauj khoom (xws li cov khoom siv daus, hnyav). Rau cov neeg yuav khoom, Astm A36 H-Cis muaj kev paub tseeb, kev ua tau zoo ib yam rau feem ntau cov kev xav tau cov kev xav tau.
Q: Cov no puas yog h - Beams zoo rau cov tsev lag luam ware36 / Q235b tsim muaj peev xwm zoo rau cov av nkos, uas loj load muaj peev xwm yog qhov tseem ceeb. Cov chaw ua lag luam feem ntau xav tau qhib chaw kom ua kom tiav cia, thiab cov beasts} qhov loj me me) thaum txhawb nqa cov khoom siv hluav taws xob hauv pem teb, forklifts, lossis khoom loj. Ib tug 300mm- be} be} nqaj} pa taws ua haujlwm rau theem nrab-} lub ntsej muag yog qhov zoo tagnrho rau cov kab ntawv pab txhawb nqa. Cov txheej txheem welded welded tso cai rau kev cai loj, yog li koj tuaj yeem tau txais cov nqaj uas haum rau koj lub chaw ua haujlwm ntev tshaj plaws (piv txwv li}} dav ywj pheej rau txuas hauv pem teb lawj). Lawv kuj yooj yim rau weld rau cov thav duab steel lossis cov pob zeb ua ke, ua kom muaj cov qauv sib zog. Rau sab nraum zoov lossis siab - noo noo noo noo, cov nqaj tuaj yeem yog galvanized lossis pleev xim kom tsis txhob muaj xeb. Rau cov neeg yuav khoom lag luam tsev, cov no h {l {Beams muaj cov kev ua tau zoo thiab lub zog xav tau los tsim lub luag haujlwm, ntev}} kav chaw.
Q: Puas yog cov h - Beams yuav siv rau cov vaj tsev welded (tshwj xeeb} Cov tsev ua hauj lwm zoo welds, tshwj xeeb yog cov tsev nyob nrog cov tsev niaj hnub nrog qhib kev teeb tsa. Lawv lub zog tso cai rau lawv mus rau ncua 6-8 meters tsis muaj ib kab ntxiv, tsim cov chav nyob lossis chav ua noj. Ib tug 200mm {{{{}} Lub taub hau sib sib zog nqus (thaum cov neeg muaj rooj tog zaum ua ke)}} Cov tsim welded tsim cov npoo du ua rau nws yooj yim rau txuas nrog lub tshuab ziab khaub ncaws, flooring, lossis lub tshuab ziab khaub ncaws. Piv rau cov nqaj ntoo, lawv tau ruaj khov dua (tiv taus rot, termites, thiab hluav taws nrog kev kho mob) thiab xav tau kev kho mob tsawg dua. Lawv kuj ua tau nrog cov lej hauv tsev hauv ntau lub teb chaws, yog li koj yuav tsis ntsib teeb meem nrog kev soj ntsuam hauv zos. Rau cov neeg yuav khoom lub tsev tsev, cov no h- cov kab teeb tsa muaj cov khoom siv niaj hnub no rau cov khoom siv tsoos.
Q: Ua li cas cov no h - Beams ua hauv Welded Steel thav ntawv, raws li lawv tau tsim los ua ke nrog lwm cov welded Cheebtsam. Lawv lub vev xaib thiab Flange flange thooj txheej txheej zoo dua nrog cov hlau txhua lossis cov paib, ua kom cov khoom siv hluav taws xob muaj zog, cov khoom siv sib txuam ua ke ntawm cov ncej. ASTM A36 thiab Q235B Weldability txhais tau tias koj tuaj yeem siv cov hau kev (MIG, TIG, STAB VUAM) Tsis Muaj Kev Sib Tw, Txawm Rau Ntawm- Cov Duab Los Ua Ke. Nyob rau hauv ib lub welded steel thav duab rau ib rhiav, piv txwv li, cov teeb meem no, cov kab teeb tsa uas tiv taus cua lossis seismic rog. Cov nqaj 'tsim welded sib koom tes kuj tau kuaj rau shear lub zog, yog li lub nqaj nws tus kheej yuav tsis poob ntawm cov tsiaj hauv qab. Rau cov neeg yuav khoom tsim Welded Steel thav ntawv, cov no h} Beams txuag sijhawm thiab xyuas kom cov ncej ntev- lub sij hawm ruaj khov.
Q: Puas yog cov h - Beams yuav siv rau kev tiv thaiv sab nraum zoov? A: Yog, cov ntaub ntawv pov tseg rau sab nraum zoov {}} nrog kev tiv thaiv corrosion. Txij li thaum lawv muaj cov hlau steel, lawv tau mus rau cov dej nag thaum muaj cov nag, av noo, lossis dej qab ntsev, yog li ntxiv txheej tiv thaiv yog qhov tseem ceeb. Qhov kev xaiv zoo tshaj plaws yog kub {{- dip galvanizing: ntswj nqaj hauv Molten Zinc Tsim ib txheej uas tsis kam muaj xeb rau 20-30 xyoos. Rau cov peev nyiaj tau nyiaj ntau ntxiv {{11} Kev xaiv huab cua, siv huab cua {12} {resortant epoxy lossis polyurethane pleev xim, uas kav sijhawm ua ntej rov ua dua. Ib 250 hli - qhov tob h} Beach ua haujlwm zoo rau sab nraum zoov thav ntawv, ncua 5-6 los npog tsheb. Cov tsim welded tsim lub zog ua kom cov nqaj tuaj yeem lis cov roj av kov tau (hauv cov huab cua txias) lossis cua (hauv ntug hiav txwv). For buyers building outdoor structures, these H-beams offer a cost-effective solution-just remember to add corrosion protection.
4. Kev txiav txim & Kev nug customization
Q: Dab tsi yog qhov tsawg kawg nkaus lag luam wholesale kev txiav txim kom muaj nuj nqis (moq) rau cov qauv welded yog kom muaj nuj nqis welded - ua hauj lwm zoo. Qhov ntau ntxiv txhais tau tias yuav tsum tau kwv yees li 20-40 nqaj, nyob ntawm loj {}} Be} Beams (24 kg / m, 12m ntev) yog li 35 teeb. Peb nkag siab tias qee tus neeg yuav khoom yuav xav tau cov khw muag khoom lag luam me me, yog li peb tau txo cov moqs (5 metric tons (5 Metric tons) rau cov neeg siv khoom ntev lossis ntev} Kev Cog Lus. Rau kev cai - qhov chaw teeb meem loj lossis kev kho mob tshwj xeeb (zoo li cov galvanizing), MOQ yog 15 Metric tons los npog cov nqi teeb tsa rau cov txheej txheem welded. Peb pab pawg muag khoom tuaj yeem pab koj suav qhov muaj kom muaj kom muaj rau koj qhov kev txiav txim siab wholesale, ua kom koj tsis omersock thaum sib ntsib lub moq.
Q: Kuv puas tuaj yeem txiav txim rau cov neeg siv tau ntau thiab tsawg rau kev lag luam wholesale ua lag luam welded ua kom muaj kev hloov pauv ntawm cov qauv sib npaug ntawm cov qauv. Txawm hais tias koj xav tau ib qho tsis-} tus qauv ntsuas (160 hli), peb lub Hoobkas tuaj yeem tsim nws rau koj qhov kev txiav txim siab wholesale. Txhawm rau thov kev cai rau kev cai thiab yooj yim qhia koj qhov kev xav tau (qhov tob, istm A36 / Q235B), thiab peb pab neeg qib steel (thiab peb pab neeg qib chaws hlau Cov kev cai sib xyaw siv 2-3 lub lis piam ntev dua cov kab teeb ci txheem (vim kev cuab yeej hloov kho thiab kuaj xyuas), tab sis peb tuaj yeem ua kom haum nrog koj cov khoom xa khoom lag luam. Tag nrho cov teeb kab teeb cig nyob rau hauv cov tshev zoo tib yam li cov qauv, suav nrog Weld kev ntsuam xyuas thiab cov ntaub ntawv pov thawj. Rau cov lag luam wholesale cov lag luam, kev coj noj coj ua tau txhais tau tias koj tau teeb ci uas haum rau koj txoj haujlwm qhov kev xav tau, txo cov khib nyiab thiab ntawm {} lub vev xaib hloov kho.
Q: Koj puas muab cov kev kho nyob rau saum npoo hlau Cov kev xaiv nrov tshaj plaws yogKub - dip Galvaning: Beams yog dipped nyob rau hauv molten zinc, tsim kom tuab, durable txheej uas tiv nuj rau sab nraum zoov lossis siab {} noo noo cov dej num. Peb kuj muabEpoxy Painting: Lub siab - Zoo} zoo }း muaj cov xim av noo thiab tshuaj lom neeg, haum rau sab hauv cov dej num zoo li cov khoom ntim khoom hauv chaw khaws khoom.
