DX51D Steel yog dab tsi?
DX51D yog ib qho uas feem ntau siv txias - dov structural steel qib teev nyob rau hauvTS EN 10346, feem ntau yog tsim los ua kom kub kub -dip galvanizing. Lub hauv paus steel DX51D muab kev ua haujlwm zoo heev, thaum lub zinc txheej txhim kho corrosion kuj thiab kev pabcuam lub neej.
Galvanized steel hais txog carbon steel coated nrog ib txheej ntawm zinc, uas ua raws li ib tug tiv thaiv barrier thiab sacrificial anode, tiv thaiv xeb tsim txawm thaum lub nto yog khawb.
Z275 txhais tau tias tag nrho cov zinc txheej loj yog275 g / m² (ob sab), muab kev tiv thaiv muaj zog nyob rau hauv ib puag ncig hnyav xws li kev tsim kho sab nraum zoov, thaj chaw ntub dej, thiab ntug hiav txwv.

Cov lus nug nquag nug (FAQ)
Q: Kub-dip galvanized steel ua li cas?
A: Kub-dip galvanized steel yog tsim los ntawm immersing hlau nyob rau hauv ib da dej ntawm molten zinc, tsim ib txheej galvanized uas muab zoo heev corrosion kuj. Cov txheej txheem no ua kom muaj kev sib raug zoo ntawm zinc txheej thiab steel substrate.
Q: Dab tsi yog qhov txiaj ntsig ntawm kev siv lub galvanized steel kauj hauv kev tsim kho?
A: Galvanized steel coils muaj kev tiv thaiv corrosion zoo heev, ua haujlwm ntev, thiab kev saib xyuas qis, ua rau lawv zoo tagnrho rau kev tsim kho. Lawv kuj muaj ntau yam thiab tuaj yeem tsim tau yooj yim rau hauv ntau yam duab.
Q: Ua li cas ua ntej- pleev xim rau galvanized steel txawv los ntawm cov hlau tsis tu ncua?
A: Pre-painted galvanized steel yog coated nrog ib txheej xim rau kev tiv thaiv ntxiv thiab zoo nkauj. Qhov no coated steel ntawv hom muab zoo heev corrosion kuj thiab ib tug txaus nyiam tiav, ua rau nws haum rau pom daim ntaub ntawv.
Q: Dab tsi yog qhov tseem ceeb ntawm "z275" kos rau ntawm cov khoom siv hlau galvanized?
A: Lub cim "z275" qhia qhov hnyav ntawm zinc txheej, ntsuas hauv grams ib square meter. Z275 galvanized steel khoom muaj zinc txheej hnyav ntawm 275 g / m², muab kev tiv thaiv corrosion tseem ceeb.
Q: Dab tsi yog lub luag haujlwm ntawm cov pa roj carbon steel ua si hauv cov khoom ntawm galvanized steel ntawv?
A: Cov pa roj carbon steel yog cov khoom siv rau cov nplooj ntawv galvanized. Nws muab lub zog thiab kev ncaj ncees, thaum lub galvanized txheej muaj corrosion kuj.
