H Daim Hlau Beam S275JR Cov Qauv Hlau

S275JR H-Beams yog ib qib txheej txheem hlau txhais los ntawm European Standlic en {2}}, uas qhia meej cov lus qhia kev mob rau cov hlau tsis-alloy. "S" sawv rau cov qauv hlau, "275" sawv rau qhov tsawg kawg ntawm MPA thiab "JR" sawv rau qhov kev ntsuas zoo rau kev cuam tshuam rau chav nyob (20 degree).

S275JR H-Beams muaj nyob rau ntau qhov ntau thiab tsawg rau:

Qhov siab (h): feem ntau yog li ntawm 100 hli txog 1000 mm.

Dav (B): ranges los ntawm 50 hli rau 400 hli.

Web tuab (tw): nruab nrab ntawm 5 hli thiab 20 hli.

Flange thickness (TF): Ranges los ntawm 6 hli mus rau 30 hli.

Gnee's S275JR H-puab hlau nqaj yog feem ntau ua haujlwm siv ib qho ntawm cov hauv qab no:
Kub Rolling: Cov hlau yog rhuab thiab dhau los ntawm cov menyuam kom ua tiav qhov xav tau.
Vuam: Cov seem yog welded ua ke los ua tus h-puab hlau profile.
Tom qab kev sib sau, cov nqaj yog cov tshuaj kho cua sov (ib txwm muaj los yog kev ntxhov siab relieving) los txhim kho cov khoom siv tshuab.

Qhov Zoo ntawm S275JR H-Zoo Shape

Nruab nrab lub zog-rau-hnyav piv: Haum rau nruab nrab cov ntawv thov txheej txheem dej num.

Ductility zoo thiab formability: yooj yim txiav, khoov thiab weld.

Tus nqi-ua tau zoo: Cov khoom qis dua tus nqi tau muab piv rau cov xim qib siab dua.

Txhim khu kev qha ua tau: Cov cuab yeej siv cov neeg kho tshuab yog qhov ruaj khov thiab ua tau zoo yog kwv yees tau.

Gnee's S275JR Cov Qauv H-Zoo Sharped Hlau Beam ua raws li cov qauv hauv qab no European:

En 10025-2}: cov khoom siv cov kev qhia rau cov hlau tsis-alloy qauv hlau.

En 10365: Cov txheej txheem kub ua tiav cov qauv hlau.
CE Malement: Ua kom ua raws li EU kev nyab xeeb, kev noj qab haus huv thiab ib puag ncig.
