0.18 - 2.5 mm Thickness Aluzinc Coated Steel , Hot - Dip GL Sheet For Appliances
Profile :
Galvalume Steel Is Tthe Plating Coat Of Aluminum-zinc Alloy Armor
Plate,And Its Composition Is 55 % Al , 43.4 % Zn And 1.6 % Si . The
Plate With Smooth Surface And Excellent Corrosion Resistance Of The
Atmosphere , Which Is 2 To 6 Times Higher Than Hot-Dip Galvanized
Sheet Of The Same Thickness Of Coating .

Characteristics :
GL are 3 ~ 6 times more corrosion - resistant compared to GI , but
has a similar level of processability and weldability and can
replace GI, and in particular is most suitable when replacing GI
that require thick galvanized layers and high corrosion resistance
.
Only galvanized steel sheet that is used for roofing and walls
without painting because of its unique silver spangles and
beautiful appearance and high - corrosion resistance, and is used
as a cool roofing material because of its excellent heat reflection
qualities .
Can replace aluminum gilded steel sheets because for certain
purposes of its electrical conductivity and its heat-resistance
qualities even at high temperatures that do not exceed 315 ℃ .
Has greater surface hardness than GIs , and is much more wear -
resistant .
Corrosion resistance increased more with resin-coating treatment ,
which enables roll forming or press forming without the spraying of
processed oils .
Application of Aluzinc Coated Steel :
Infrastructure : Roofing / External Siding / Garage / Shutter
Household Appliances : Oven / Air - Conditioning Ventilation System
/ Solar Water Heater / Electronics
Automobile : Mobile Muffler / Vent Pipe / Catalysis Converter
Heater Shield / Bottom Accessories
Industrial Instrument : Electric Control Cabinet / Industrial
Freezer Chest
