1219mm Width Anti Rust Galvalume Steel Coil Impact Resistance For Metal Roof
The Aluzinc cladding steel coil apply hot dip Al-Zn coating on both faces of cold rolled steel of different strength and thickness. In its coating, Al accounts for about 55%, Si 1.6%, others are Zn. Compared to hot dip galvanize steel , galvalume steel has better anti-corrosion ability. Fingerprint resistant oil also make its service life longer.

Surface Treatment Of Galvalume Steel Coil
| Surface Treatment | Feature |
| Chemical Treatment | minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
| retain the bright metallic luster for a long period | |
| Oil | minimize the tendency for humid-storage stain |
| Chemical Treatment and Oil | The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations. |
| Dry | must be transported and stored with special precautions to preserve low-humidity conditions. |
| Anti-finger print | minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |

Application Of Galvalume Steel Coil
1. Architecture Roofs and outside walls of civilian and industrial buildings, garage doors, fencings and window blinds
2. Appliances Industry Outer clad sheets for washing machine, refrigerator, television, air conditioner and ventilation system, explosion-proof strip, solar water heater and appliance parts
3. Auto Industry Muffler, heat shields of exhaust pipe and catalytic converter, auto parts & accessories under the frame, signboard in highway
4. Industrial Instruments Electric control cabinet, industrial refrigeration equipment, automatic vending machine
Features Of Galvalume Steel Coil
1. Resistance to Corrosion Has better performance in corrosion resistance than hot dip galvanized coil/sheet of the same thickness and its service life is 1-5 times longer than general hot dip galvanized coil/sheet.
2. Machinability Can satisfy the processing requirements of rolling, coiling and others processes alike.
3. Thermal Resistance Can sustain the environment at 315°C for long time.
4. High Reflectivity Reflection ability of heat and light is twice as much as those of hot dip galvanized steel coil/sheet, and its reflectivity is more than 0.75, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction material of saving energy
