Lub kaum sab xis steeltransmission towers yog cov khoom siv hluav taws xob sib txuas lus txhawb nqa cov qauv nrog lub kaum ntse ntse hlau ua lub ntsiab lus tseem ceeb. Feem ntau siv sib npaug- ceg kaum steel (xws li L50 × 5, L160 × 16) thiab tsis sib npaug - ceg kaum steel (xws li L100 × 80 × 8) yog siv, thiab cov ntaub ntawv feem ntau yog qis- alloy siab{11}} lub zog steels xws li Q235B Lub kaum sab xis steel / Q235B. Nws L-zoo li tus ntoo khaub lig- ntu muaj qhov zoo xws li siab flexural thiab torsional txhav, yooj yim ntsia liaj qhov rooj txuas, thiab cov nqi ua haujlwm tsawg.
Kev tsim thiab tsim khoom ntawm lub kaum sab xis steel xa cov yees feem ntau ua raws li lub teb chaws lossis cheeb tsam fais fab engineering cov qauv thiab cov lus qhia tshwj xeeb kom ntseeg tau tias lawv muaj kev nyab xeeb thiab kev ntseeg tau. Nws cov yam ntxwv tseem ceeb muaj xws li:
Cov qauv yooj yim: Cov kav hlau xa mus yog ua los ntawm cov khoom siv lub kaum ntse ntse, nrog cov qauv yooj yim thiab ruaj khov, haum rau cov kab sib txuas ntawm nruab nrab voltage theem.
Yooj yim installation:Kev sib dhos thiab kev teeb tsa ntawm lub kaum sab xis steel kis tau tus yees yog qhov yooj yim, thiab kev tsim kho thiab kev sib txuas ntawm ntauwd lub cev tuaj yeem ua tiav sai.
Muaj zog huab cua tsis kam:Lub kaum sab xis steel xa cov yees feem ntau dhau los tiv thaiv- kev kho corrosion, xws li kub-dip galvanizing, txhawm rau txhim kho lawv cov tshuaj tiv thaiv -oxidation, tiv thaiv- corrosion, thiab huab cua tiv thaiv kev ua haujlwm thiab txuas ntxiv lawv lub neej kev pab cuam.
Lightweight tsim:Lub kaum sab xis steel xa mus yees siv lub teeb yuag tsim thiab txhim kho cov qauv kom txo tau qhov hnyav tag nrho thiab txhim kho lawv cov cua tsis kam thiab muaj peev xwm ua rau seismic.

Peb tau tsim nyob rau hauv 2008 thiab tam sim no tau tsim los rau hauv ib qho kev sib koom ua ke steel khoom lag luam. Tom qab xyoo ntawm txoj kev loj hlob, lub tuam txhab muaj kev tsim khoom, kev yuav khoom, kev lag luam, kev muag khoom, thiab pab pawg tswj hwm ntawm ntau tshaj 200 tus neeg, lub Hoobkas cheeb tsam ntawm ntau tshaj 35,000 square meters. Lub tuam txhab cov khoom siv hlau raug xa tawm mus rau ntau tshaj 200 lub teb chaws thiab cheeb tsam thoob plaws ntiaj teb thiab tau siv dav hauv ntau qhov chaw xws li kev tsheb ciav hlau, tsheb ciav hlau, nkoj thauj tog rau nkoj chains, petrochemicals, offshore engineering, nuclear zog, thiab cua zog.
Peb pab neeg muaj kev paub nplua nuj thiab lub Hoobkas muaj zog hauv kev tsim ntau yam kev qhia ntawm lub kaum sab xis steel. Ntxiv rau qhov saum toj no - cov khoom tau hais, peb kuj muab ntau yam khoom siv hlau kom tau raws li qhov kev xav tau sib txawv. Yog tias koj muaj kev xav tau, thov hu rau peb.beam@gneesteel.com
