G550 Galvalume Aluzinc Coated Steel Coil for Exterior
G550 Galvalume Aluzinc Coated Steel Coil for Exterior
Feature
-
Galvalume Aluzinc Coated Steel Coil is a kind of derecho alloy material that is broadly applied in production and life fields including building, vehicle, appliance, and farm. This product realizes the surface of steel plates coated with aluminum-zinc alloy structure, compounding the sacrificial protection effect of zinc and barrier protection effect of aluminum. It can show excellent corrosion resistance under most atmospheric conditions. The coating quantity of G550 galvalume steel coil is 2~6 times of that of hot-dip galvanized steel sheet.

Galvalume Steel Coil has the following advantages:
1. It has good formability, weldability and paintability, which can be processed with all kinds of forming processing methods;
2. The alloy coating contains 55% aluminum, 43.5% zinc, and 1.5% silicon and provides a dual protection system - zinc's sacrificial anode protection, and aluminum's dense barrier protection;
3. In general corrosion environments, the corrosion resistance of Galfan is better than most traditional pure galvanized steel products, and the nominal service life could be up to 2-6 times of the latter;
4. The zinc flakes on the surface are beautiful and uniform, and not only meet the requirements of the strength of structure, but also can be taken as exposed decorative plate for building.
The G550 Galvalume Aluzinc Prepainted Steel Coil is applicable to these fields:
1. In the construction: roof, wall, garage, soundproof wall, pipe and house with modul, etc.;
2. Automotive industry: mufflers, exhaust pipes, windshield wiper components, fuel tanks, truck compartments, etc.;
3. Home Appliance: fridge back plate, gas stove, air conditioner, electronic microwave oven, lcd frame, crt explosion proof strip, led back light source, electric cabinet, etc.;
4. Agriculture use: pig house chicken house, grain store, greenhouse pipe etc.;
5. Others: heat shield, heat exchanger, dryer, water heater, etc.

A1: Alloy coating of this product is 55% aluminum, 43.4% zinc and 1.6% silicon in the aluminum-zinc sheet. It is matured and shaped at 600 ℃ and has the double effects of the barrier protection of aluminum and the sacrificial protection of zinc.
A2: It meets the product multi standard, such as AISI, ASTM, BS, DIN, GB, JIS etc.
A3: Yes. The thickness range is 0.16mm-2.5mm. The width can be fully customized to customer requirements. The length is also produced according to the customer's requirements. The roll weight can be tailored to suit the order as well.
A4: You can choose from a range of surface treatment options including chemical treatment, oil coated, dry treated, chemical treated + oil coated, anti-fingerprint treatment. Surface treatment The advantage of each treatment being different for moisture passivation, rust passivation, lubrication and appearance keeping. Please refer to the characteristics of surface treatment in the above.
A5: G550 Galvalume galvanized zinc steel coil corrosion resistance is more than that of normal pure galvanized steel sheet 3 times.
