  Galvalume Steel Coil   Brief Introduction The Galvalume Steel Coil 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 Zn. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.   Production Flow Chart Specification 1. Thickness: 0.3-0.8mm 2. Width: 914-1250mm 3. Inner Diameter: 508mm 4. Weight of Steel Coil: 3-15MT 5. Coating Type: Al-Zn Alloy 6. Available Dipped Layer: 50-150g/m2 7. Surface Finish Structure: Normal Spangle & Small Spangle & Zero Spangle 8.

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   Certificates   Quality Control & Test Instruments   Production Line   Factory Overlook   Superiority 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.
