DX51D+Z Kub-Dip Galvanized Steel Sheet nta
DX51D + Z galvanized steel ntawvyog tsim los ntawm immersing txias- dov steel rau hauv ib tug molten zinc da dej, tsim ib tug tiv thaiv zinc txheej ntawm qhov chaw.
Txoj kev siv ntau tshaj yog nruam kub -dip galvanizing, qhov twg cov hlau kauj dhau los ntawm cov zinc da dej tsis tu ncua, ua rau cov txheej txheem galvanized.
Rau alloy-coated galvanized steel, tom qab dipped nyob rau hauv zinc, cov hlau yog rhuab mus rau kwv yees li 500 degree, ua ib zinc- hlau alloy txheej. Cov txheej txheem no txhim kho txheej adhesion, corrosion kuj, thiab weldability, ua DX51D + Z haum rau kev tsim kho, tsheb, thiab khoom siv.

DX51D + Z steel ntawv tuav cov ntsiab lus qis rau kev tsim tau zoo thaum muab cov manganese thiab txhuas txaus los txhim kho lub zog thiab txheej adhesion.
Kev ua tau zoo ntawm DX51D + Z thiab Al-Zn Coated Steel
Siab Thermal Reflectivity
Aluminium-zinc coated steel ua rau pom qhov thermal reflectivity kwv yees li ob npaug ntawm cov qauv galvanized steel, ua rau nws zoo tagnrho rau rwb thaiv tsev vaj huam sib luag thiab cua sov- daim ntawv thov kev cuam tshuam.
Thaum tshav kub kub Resistance
Al-Zn alloyed steel withstands kub tshaj 300 degree, nrog oxidation kuj zoo ib yam li txhuas plating. Cov ntawv thov ib txwm muaj xws li cov kav dej chimney, qhov cub, hnub ci teeb ntxoov ntxoo, thiab siab -cov khoom siv kub.
Superior Corrosion Resistance
Cov ntsiab lus txhuas ua cov txheej txheej tuab aluminium oxide raws li zinc hnav tawm, tiv thaiv cov hlau substrate thiab ua kom lub neej ntev ntawm DX51D + Z galvanized steel.
Nqi Efficiency
Nrog rau qhov ntom ntom qis (55% Al-Zn), aluminized zinc steel muaj 3% ntau qhov chaw tshaj li cov txheej txheem zinc txheej nyob rau hauv tib qhov hnyav thiab tuab, txo cov nqi khoom siv rau cov dej num loj.
Paintability zoo heev
Al-Zn coated DX51D+Z tuaj yeem pleev xim ncaj qha yam tsis muaj kev kho ua ntej -. Nws muaj zog adhesion rau coatings, haum rau advertising boards, lub tsev panels, thiab cov khoom enclosures.
Aesthetic Silver-White Surface
Al-Zn steel muaj qhov zoo nkauj ci ntsa iab, ua kom tiav, ua kom pom kev pom zoo rau kev siv vaj tsev thiab cov neeg siv khoom.
Kev ua tau zoo
DX51D+Z thiab Al-Zn coated steel khaws zoo sib xws stamping, sib sau, thiab txau cov khoom raws li ib txwm galvanized steel, ua kom muaj kev sib raug zoo nrog cov txheej txheem kev tsim khoom.

Piv txwv li - DX51D+Z140:Tag nrho cov txheej txheej tsawg kawg yog 140 g / m² (kwv yees . 20 µm ib sab, 40 µm tag nrho). Cov lej feem ntau yog Z100 (lub teeb), Z140 (tus qauv), Z200 / Z225 (hnyav), thiab Z275 (hnyav ntxiv rau qhov chaw hnyav).
Q4: Cov ntawv thov tseem ceeb rau DX51D + Z yog dab tsi?
A:Nws yog cov hlau ua haujlwm rau kev tsim khoom dav dav qhov twg corrosion kuj thiab formability xav tau, tab sistsis siab structural zog. Common siv muaj xws li:
HVAC ductwork thiab cov khoom.
Cov khoom siv hauv tsev (lub tshuab ntxhua khaub ncaws, tshuab ziab khaub ncaws, enclosures).
Lub teeb ntsuas lub tsev panels thiab profiles.
General hlau txee, enclosures, thiab lub teeb rooj tog.
Agricultural thiab industrial ntim.
