GL - Galvalume Steel Coils /Aluzinc Steel Coils
Introduction of GL-Galvalume Steel Coils/ Aluzinc Steel Coils
-
The Galvalume Aluzinc steel coils is composed of an aluminum-zinc alloy structure composed of 55% aluminum, 43.4% zinc, and 1.6% silicon solidified at a high temperature of 600 ° C. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal of an alloy.
Features of GL-Galvalume Steel Coils/Aluzinc Steel Coils
- Good formability to meet the requirements of roll forming,bending and other forms of processing.
- Excellent heat resistance,ordinary hot-dip galvanized products are usually used at temperatures not exceeding 230 degrees Celsius,250 degrees Celsius will change color,aluminum-dip galvanized sheet is different.it can be used at 315 degrees Celsius for a long time.
- Super high reflectivity,55%aluminum zinc reflecting heat and light,which is two times capacity of hot-dip galvanized steel sheet.The reflectivity is greater than 0.70.which is better than 0.65 of EPA ENERGY STAR.It is an ideal building material for energy conservation.
- Excellent corrosion resistance,55%aluminum-galvanized steel sheet has better corrosion resistance than the same thickness of hot-dip galvanized steel sheet,with same thickness and same content percentage of al-zinc,life is 2-6 times more than ordinary galvanized steel sheet.
Application of GL-Galvalume /Aluzinc Steel Coils
Construction: Roofs, Walls, Garages, Acoustic Walls, Plumbing and Modular Houses, etc.
Automotive: mufflers, exhaust pipes, wiper attachments, fuel tanks, truck boxes, etc.
Home appliances: refrigerator back panel, gas stove, air conditioner, electronic microwave oven, LCD frame,
CRT explosion-proofbelt, LED backlight, electrical cabinet, etc.
Agricultural use: pig house, chicken house, granary, greenhouse pipes, etc.
Others: Thermal insulation cover, heat exchanger, dryer, water heater, etc.
AFP -Anti-finger and Non Anti-Finger Surface
Galvalume steel sheets can be divided into anti-finger(AFP) and Non-antifungal.
Anti-finger includes color anti-finger and colorless anti-finger.
Anti-fingerprint refers to coating a layer of anti-fingerprint liquid on the surface of a galvalume steel coil to prevent oxidation. Since human sweat and aluminized zinc are easily oxidized, a layer of anti-fingerprint liquid is applied to increase the service life of the Galvalume steel sheet.
