Xov xwm
Nyob rau hauv cov txheej txheem steel tej yaam num, cov khoom ua tau zoo ib leeg tsis txaus los lav kev ua tiav. Kev sib txuas lus meej thiab kev tshaj lij ntawm cov neeg muag khoom thiab cov neeg siv khoom tau dhau los ua qhov tseem ceeb, tshwj xeeb tshaj yog thaum sib tham nrogS280GD txheej txheem galvanized steel, qib siv dav hauv kev thauj khoom -cov kabmob thiab ib nrab- thauj khoom- cov ntawv thov kabmob.
S280GD yog txhais raws li EN 10346 raws li cov qauv steel qib nrog qhov tsawg kawg nkaus yield zog ntawm 280 MPa, ua ke nrog kub -dip galvanizing rau kev tiv thaiv corrosion. Vim tias qib no nyob nruab nrab ntawm lub teeb tsim steels thiab siab dua - qib ntawm cov qauv, nws feem ntau xav tau kev sib tham ntxaws ntxiv ua ntej xaiv cov khoom siv zaum kawg.
Cov txheej txheem galvanized steel feem ntau yog siv rau hauv cov tshuab uas qhov tseeb qhov tseeb, kev ntseeg tau ntawm cov khoom siv, thiab kev ua haujlwm saum npoo tag nrho ua lub luag haujlwm tseem ceeb. Kev nkag siab yuam kev ib yam ntawm cov xwm txheej no yuav ua rau muaj teeb meem kev tsim khoom lossis kev ua haujlwm sib txawv tom qab kev teeb tsa.
Rau S280GD galvanized steel, kev sib txuas lus feem ntau yog tsom rau cov hauv qab no:
| Technical Aspect | Kev cuam tshuam |
|---|---|
| Yield zog xav tau | Txiav txim siab load-bearing peev |
| Tensile zog ntau yam | Muaj feem xyuam rau kev nyab xeeb |
| Zinc txheej thickness | Influences corrosion kuj |
| Kev coj cwj pwm | Impacts dabtsi yog khoov thiab vuam |
Kev qhia meej meej ntawm cov kev txwv no pab xyuas kom meej tias cov khoom siv S280GD tau xaiv ua raws li qhov xav tau tiag tiag ntawm qhov project es tsis yog qhov kev xav.
Hauv ntau txoj haujlwm, S280GD cov qauv hlau tau ua tiav rau hauv cov profiles, thav ntawv, lossis cov khoom txhawb nqa los ntawm yob txoj kev los yog dabtsi yog khoov. Txawm hais tias qib muaj lub zog txaus rau kev siv cov qauv, cov txheej txheem tsim kom zoo yuav tsum tau saib xyuas kom tsis txhob muaj qhov tawg los yog qhov txawv txav.
Thaum lub sij hawm kev sib tham, cov ncauj lus xws li qhov tsawg kawg nkaus khoov vojvoog, tsim cov kev taw qhia txheeb ze rau dov, thiab txheej txheej txheej thaum lub sij hawm fabrication yog feem ntau hais. Cov ntsiab lus no pab cov fabricators optimize cov txheej txheem ntau lawm thiab txo cov kev sim tsis tsim nyog.
Cov txheej txheej galvanized ntawm S280GD steel yog qhov tseem ceeb cuam tshuam rau lub neej kev pabcuam. Ib puag ncig sib txawv xav tau cov txheej txheem sib txawv kom ntseeg tau ntev - lub sij hawm corrosion kuj.
| Zinc Txheej Chav Kawm | Pom zoo ib puag ncig |
|---|---|
| Z100–Z140 | Sab hauv lossis qis - thaj chaw corrosion |
| Z180–Z275 | Sab nraum zoov lossis cov qauv raug |
Los ntawm kev sib tham txog cov txheej txheem txheej thaum ntxov, cov phiaj xwm pab pawg tuaj yeem sib npaug cov kev cia siab ntev nrog cov nqi txiav txim siab.
Kev sib txuas lus tsis txwv rau cov ntawv qhia tshwj xeeb. Nws kuj suav nrog kev taw qhia ntawm daim ntawv thov, kev tshuaj xyuas kom meej meej, thiab tom qab- txhawb nqa kev xa khoom. Thaum cov neeg muag khoom nquag koom nrog hauv kev sib pauv, cov neeg siv khoom tau txais kev ntseeg siab ntawm ob qho tib si cov khoom siv thiab cov txheej txheem kev koom tes.
GNEE STEEL muab kev txhawb nqa kev tshaj lij rauS280GD txheej txheem galvanized steel, pab cov neeg siv khoom hauv kev xaiv cov khoom siv, kev taw qhia ua haujlwm, thiab kev qhia meej ntawm daim ntawv thov. Nrog kev paub dhau los hauv kev muab cov khoom siv galvanized steel rau kev tsim kho thiab kev lag luam siv, GNEE STEEL pab cov neeg siv khoom txo qhov kev pheej hmoo thiab ua tiav cov txiaj ntsig zoo.
