DX52D+AZ Galvalume Coil

Economical DX52D+AZ galvalume coil:

Since the density of 55% Al-Zn is lower than that of Zn, the area of galvalume coil is more than 3% larger than that of galvanized steel sheet under the condition of the same weight and the same gold plating thickness.

1. Corrosion resistant

   Zinc has active chemical properties. In the air at room temperature, a thin and dense alkaline zinc carbonate film is formed on the surface, which can prevent further oxidation, while aluminum can form an insoluble oxide layer in the air, which acts as a protective barrier.

2. Heat resistance

   Galvalume coils can be used in high temperature environments up to 315 degrees.

3. Reflective

   The galvalume coil has high reflectivity, and its heat reflectivity is almost twice that of galvanized steel. It is very suitable for steel structure metal roofs and can achieve energy-saving effects.

4. Easy to color

   Galvalume coils have excellent adhesion to paint and can be painted without pretreatment and weathering.

Coating properties of DX52D+AZ Galvalume Coil:

Application:

The AZ in the DX52D+AZ galvalume coil is an aluminum-zinc alloy coating. The mass fraction of aluminum in the molten aluminum-zinc alloy solution is about 55%, the mass fraction of silicon is about 1.6%, and the rest is zinc. The surface structure of the AZ coating is ordinary spangle, which is characterized by the aluminum-zinc crystal structure obtained by the normal condensation of the coating. The surface structure of the AZ coating usually has a metallic luster.

DX52D+AZ galvalume coil has excellent coating insulation protection and electrochemical protection, and is suitable for environments requiring high corrosion resistance. In addition, the DX52D+AZ galvalume coil has good high temperature resistance and heat reflectivity, and is widely used in roofs and walls. It can be used directly or as a substrate for color-coated panels.

Other applications of DX52D+AZ galvalume coil include:

• Building and construction components (envelope systems, joists for residential buildings, roofs, walls, ceilings, doors);

• Rainwater pipe fittings;

• furniture and outdoor cabinets;

• Unexposed auto parts;

• Electrical appliances (oven, heater);

• Pipes and computer cases, etc.
