Hot Dipped G550 Dx51d G30 G60 G90 Zinc Coating Z20-Z275 Galvalume Steel Coil commercial exterior building material
Hot Dipped G550 Dx51d G30 G60 G90 Zinc Coating Z20-Z275 Galvalume Steel Sheet/Coil
Galvalume Steel Coil(55% Aluminium-Zinc Alloy Coated Steel Coil)
Aluminium-zinc steel is composed of an aluminium-zinc alloy structure, consisting of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 degrees Celsius. Its entire structure consists of aluminium - iron - silicon - zinc, the formation of dense tetrameric crystals of an alloy coated steel.
Main advantages
1, smooth surface, excellent resistance to atmospheric corrosion, its corrosion resistance life is 2-6 times higher than hot-dip galvanised steel;
2, with good heat and oxidation resistance, it does not change colour for a long time under 300℃, and it can be used for a long time around 500℃. In addition, the heat reflectivity of the product is higher than 75%, which is 2 times higher than that of galvanised sheet;
3, has excellent paintability and good processing performance. The combination of machine material is strong, which is the best choice for colour coated steel sheet substrate. Its processability and weldability are similar to that of hot galvanised sheet, and it can be processed by cold bending and stamping, and has a good appearance.
Applications
Galvalume steel's superior protective characteristics and economical price make it ideal for :
- Residential and commercial exterior building materials
- Decking
- Cladding
- Cabinetmaking
For galvalume steel, we have more than 10 production lines, thickness from 0.11-2mm.
Galvalume steel coil is aluminum zinc alloy structurem it is made by 55% aluminum, 43.4% zinc and 1.6% silicon,at 600ºChigh temperature solidification and composition,its whole structure by aluminum-iron-silicon-zin, which our galvalume steel has excellent corrosion resistance. We can also offer the service of cutting and punching. We are very capable to custom make for you.
Product Description
It is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through
applying Al-Zn coat on both faces by hot dip process. In its coating,Al accounts for about 55%, Si 1.6%, while the remaining is zinc.
2. Hot Dip Galvalume Steel Coil main usage scope
1) Architecture roofs and outside walls of civilian,industrial buildings,garage doors,fencings
2) Appliances industry outer clad sheets for washing machine, refrigerator, television, air conditioner and ventilation system,explosion-
proof strip,solar water heater and appliance
3) Auto industry muffler,heat shields of exhaust pipe and catalytic converter, auto parts& accessories under frame, signboard
4) Industrial instruments electric control cabinet, industrial refrigeration equipment
3. Hot Dip Galvaume Steel Coil packing
Each aluzinc steel coil tube wrapped by plastic film and waterproof paper, one steel strip strapping on the coil circumference. 3 - 5 coils
tube packed eye vertical on wood pallet, and strongly strapped by edge protection, and at least 4 steel straps through coil eye. Coil
tube packed eye to sky on wood pallet
4. Hot Dip Galvalume Steel Coil parameter
1) Formable, weldable and paintable
2) Superior long term corrosion resistance in the most atmospheric conditions.This is achieved through the combination of the sacrificial
protection of the zinc and the barrier protection
3) Hot dip galvalume coating out-perform galvanized coating from 2-6 times than galvanized steel
