Purlins & Girts
Dab tsi yog Steel Purlins & Girts?
Purlins thiab girts yog cov tswv cuab thib ob ntawm cov hlau-cov vaj tse. Purlins khiav ntawm lub ru tsev los txhawb lub ru tsev panels thiab hloov lub ru tsev loads mus rau lub ntsiab ncej, thaum girts khiav horizontally nyob rau hauv cov phab ntsa los txhawb cov phab ntsa panels thiab tiv thaiv cua loads. Ua ke lawv khi lub tsev lub hnab ntawv mus rau thawj steel ncej.
Ob qho tib si feem ntau yog yob- ua rau C- ntu lossis Z- ntu los ntawm galvanized txias- ua hlau - lub teeb yuag, qhov dav dav, corrosion- tiv taus, thiab ceev rau nruab. Dav siv nyob rau hauv ua ntej -engineered vaj tse, industrial rhiav, warehouses, factories thiab coj mus muag qauv. Nplooj ntawv no tseem yuav pab koj xaiv ntawm C thiab Z, teem caij sib nrug, thiab xaiv txoj cai galvanizing.

Lub luag haujlwm ntawm Steel Purlins & Girts
Load Hloov
Ncaj nraim nqa cov loads tuag thiab nyob loads los ntawm lub ru tsev lossis phab ntsa panels, xws li cua loads thiab daus loads, thiab xyuam xim xa mus rau lub ntsiab rigidity.
Txhim khu kev ruaj ntseg
Tsim kom muaj kev ruaj ntseg nrog cov kab teeb ci tseem ceeb ntawm cov khoom sib txuas nrog rau cov pas nrig thiab cov hlua khi, kom tsis txhob muaj kev ruaj ntseg ntawm lub ntsiab steel ncej.
Seismic Bracing
Muab spatial restraint nyob rau hauv av qeeg los yog muaj zog cua kom nqus thiab faib cov kab rov tav sab nraud quab yuam.
Cov txiaj ntsig ntawm Steel Purlins & Girts
Siab zog & Lub teeb yuag
Tsim los ntawm cov txheej txheem txias-tsim nyias-phab ntsa nrog cov tuab tuab xws li 1.5 hli txog 3.0 hli, feem ntau hauv C-section lossis Z-section profiles. Piv nrog cov pa kub-kuav los tiag steel ntu, nws txo qhov hnyav ntawm lub ru tsev ntawm 30% -50%.
01
Precision & High Efficiency
Standardized Hoobkas prefabrication ua tiav qhov-txoj hauj lwm kam rau ua hauv qab 1 hli. Bolt-assembly tau txais los ntawm qhov chaw, txiav lub voj voog kev tsim kho los ntawm ntau dua 40% piv nrog cov qauv ua vaj tse.
02
Nqi-Effective Span Performance
Qhov kev lag luam zoo sib xws yog li ntawm 4 m txog 6 m. Thaum Z-sections raug siv nrog kev sib koom ua ke tas mus li, lub peev xwm flexural tau txhim kho los ntawm kwv yees li 30% piv rau qhov yooj yim-txhawb ib qho qauv tsim.
03
Fast Site Installation
Siab prefabricated nyob rau hauv lub Hoobkas thiab ntsia liaj qhov rooj-txuas ntawm-site tsis muaj ntub-ua hauj lwm yuav tsum tau. Kev tsim kho kev ua tau zoo yog ntau dua ob npaug piv nrog cov khoom ua vaj tse ib txwm muaj, ua kom luv luv ntawm tag nrho cov phiaj xwm phiaj xwm.
04
C vs. Z Ntus - Qhov twg Xaiv?
C-Section
Center of gravity nyob rau hauv nruab nrab -yooj yim kawg nthuav dav, haum rau me me spans, yooj yim ru tsev, phab ntsa girts thiab framed opens.
Z-Section
Nest & lap ua ke rautsis tu ncua spans- zoo tagnrho rau cov ru tsev loj loj thiab ntev lub ru tsev khiav. Lub zog txhim kho nrog lap-kev sib txuas ntxiv.
Txoj cai ceev: lub ru tsev loj → Z; yooj yim luv luv spans & phab ntsa girts → C. Tseem tsis paub →xa koj loading, peb mam li lees paub.
Yuav Ua Li Cas Xaiv: Ua Ntej Ua Ntej -Pass
Kev xaiv yog tsav los ntawmspan, loads thiab raug. Qhov kev siv ceev no tau txais koj qhov chaw pib - peb lees paub qhov kawg ntu, sib nrug thiab txheej tiv thaiv koj daim duab.

FAQ:
Qhov txawv ntawm qhov txias- tsim thiab kub- dov purlins yog dab tsi?
Txias-formed purlins yog yob- ua los ntawm cov ntawv nyias galvanized - sib dua, corrosion ntau dua- tiv taus thiab nrawm dua rau nruab, ua rau lawv xaiv kev lag luam rau cov tswv cuab theem nrab. Kub-khoov seem yog hnyav dua thiab siv feem ntau hauv thawj framing.
purlins thiab girts ntsia thiab txuas nrog cov qauv li cas?
Lawv yog bolted los yog clipped rau lub ntsiab ncej - purlins rau lub ru tsev kab teeb, girts rau txhua. Nyob rau hauv ntev spans, sag rods khi lub purlins thiab cua -bracing ties lub girts rau tus ncej. Peb muab ib daim ntawv qhia kev teeb tsa nrog txhua tus xa khoom.
galvanized purlins thiab girts ntev npaum li cas?
Kev pabcuam lub neej nyob ntawm cov zinc txheej thiab ib puag ncig: Z275+ txheej ua haujlwm tau ntau xyoo hauv cov huab cua feem ntau. Peb muab cov ntawv pov thawj txheej kom koj tuaj yeem txheeb xyuas qhov tshwj xeeb tiv thaiv koj cov kev xav tau.
Dab tsi ncua thiab thauj khoom tuaj yeem nqa koj cov purlins?
Lub peev xwm nyob ntawm qhov seem, qhov sib txawv thiab cov khoom siv. Peb muab cov ntaub ntawv pov thawj ncua / thauj khoom sib npaug rau koj daim duab kos thiab koj lub zos cua thiab daus qhov tseem ceeb - lees paub nrog cov lus tsocai.
