Kab thiab kab

 

 

A steel kemyog ib tug ntsug load- bearing cov tswv cuab uas hloov compressive loads ntawm kab, pem teb, thiab ru tsev mus rau lub hauv paus. Asteel nqajyog ib tug kab rov tav cov tswv cuab uas nqa loads hla ib ncua thiab hloov mus rau txhua kab los yog phab ntsa. Ua ke lawv tsim cov load- bearing thav duab ntawm ib lub tsev: lub load mus los ntawm lub slab, los ntawm lub beam, mus rau hauv kem, thiab nqes mus rau lub hauv paus. Xaiv cov seem thiab qib zoo rau txhua lub luag haujlwm yog qhov ua kom tus qauv muaj kev nyab xeeb thiab kev lag luam.

 

 

 

Txhua hom haum rau qhov sib txawv load, ncua, thiab zoo nkauj. Ntawm no yog txhua tus yog dab tsi, qhov twg nws haum, thiab vim li cas xaiv nws.

 

 

 

Cov pawg saum toj no yog cov qauv txheej txheem cov tswv cuab hom siv hauv kev tsim steel. Peb tsim nyob rau hauv txhua hom; tsis yog- cov qauv txheem tuaj yeem tsim kho raws li kev thov.

 

 

Txhawm rau hais kom raug, xa peb ib qho ntawm cov hauv qab no (ib daim duab txaus los pib):

 

 Kev kos duab- DWG, PDF, lossis kos duab yooj yim.

 Tshaj & thauj khoom- bay loj, pem teb / ru tsev loads, cua lossis seismic yuav tsum tau (peb tuaj yeem pab xam).

FAQ

 

Koj puas muab engineering lossis tsim kev txhawb nqa yog tias kuv tsis muaj daim duab tag nrho?

 

Yog lawm. Yog tias koj lub thav duab steel tseem nyob ntawm lub tswv yim theem, peb cov kws tsim qauv tsim tuaj yeem loj cov kab thiab kab teeb ntawm koj qhov kev ncua, thauj khoom, thiab kev teeb tsa bay, tom qab ntawd tsim cov duab kos koj xav tau.

 

Ntev npaum li cas cov kab hlau thiab kab teeb kav ntev?

 

Nrog cov txheej txheem tsim nyog thiab kev saib xyuas, lub thav duab steel ua haujlwm tau ntau xyoo. Kub-dip-galvanized lossis zoo- cov neeg pleev xim rau sab nrauv tiv thaiv corrosion tau ntau xyoo yam tsis muaj kev ua haujlwm loj.

 

Puas yog steel kab thiab kab hluav taws kub-resistant?

 

Raw steel poob lub zog ntawm qhov kub thiab txias, yog li thaum lub foob hluav taws xav tau nws peb ntxiv kev tiv thaiv - intumescent txheej lossis encasement - qhov loj me rau tus tswv cuab qhov kev ntsuas hluav taws kub thiab qhia koj qhov kev xaiv tiav.

 

Dab tsi yog qhov txawv ntawm kub - dov thiab welded ua - cov tswv cuab?

 

Kub-khoov seem yog cov txheej txheem xa tawm los ntawm lub zeb, zoo tagnrho rau cov spans. Welded ua-cov tswv cuab yog tsim los ntawm cov phaj rau koj qhov ntev, qhov zoo tshaj plaws yog tias tus qauv tsis tuaj yeem nqa lub nra lossis haum rau qhov ntev.

 

Dab tsi txiav txim siab tus nqi ntawm ib kab hlau los yog kab?

 

Feem ntau yog tsib yam: raw steel nqi, kom muaj nuj nqis, qib steel, fabrication complexity (txiav, vuam, nto kho), thiab hiav txwv freight rau koj qhov chaw nres nkoj. Xa koj cov duab kos thiab ntau thiab peb ua txhua yam.

 

Kuv tuaj yeem tuaj xyuas lub Hoobkas lossis pom cov khoom ua ntej?

 

Zoo siab txais tos. Koj tuaj yeem ncig xyuas peb lub rooj cob qhia, saib cov vuam thiab QC, thiab txawm teem caij thib peb -kev tshuaj xyuas ua ntej xa khoom. Yog tias koj tuaj yeem tuaj xyuas tsis tau, peb yuav xa cov yeeb yaj kiab thiab cov duab tshuaj xyuas.

 

Koj puas xa tuaj rau kuv lub tebchaws / cheeb tsam?

 

Peb muab 40+ lub teb chaws thoob plaws Asia, Europe, Africa, Americas, thiab Oceania, los ntawm cov thawv tsis tu ncua, LCL, tiaj tus khib, lossis tawg ntau. Qhia rau peb qhov chaw nres nkoj qhov chaw thiab peb paub meej tias qhov zoo tshaj plaws routing.

 

Dab tsi nto tiav thiab txheej txheej xaiv muaj?
