What is the material of galvanized sheet

Galvanized plate refers to the surface is coated with a layer of zinc steel plate, and galvanized belongs to a kind of economic and effective rust prevention method is often used, galvanized plate because of the plating process in the treatment of  different, the surface state is different, such as ordinary zinc flowers, fine zinc flowers, flat zinc flowers, zinc flowers and phosphating treatment of the surface, but also in the German standard has the surface level.

Two, the advantages of galvanized steel plate

1. Processing performance

Aluminized zinc steel plate is comparable to hot-dip galvanized steel in processing properties, and can fully meet the requirements of roller pressing, stamping, bending and other forms of processing.

2. Corrosion resistance

The test in the same thickness, coating, surface treatment of hot galvanized steel plate and aluminum plated zinc plate before the question, it is enough to prove that aluminum zinc plating than hot galvanized steel has excellent corrosion resistance, and the service life is 2-6 times that of ordinary galvanized steel plate.

3. light reflection performance

Aluminized zinc reflects heat and light twice as well as galvanized steel, with a reflectivity greater than 0.70, better than the 0.65 defined by EPA Energy Star.

4. heat resistance

Ordinary hot-dip galvanized products generally in the use of temperature does not exceed 230 degrees, 250 degrees will produce discoloration, and aluminum zinc plating plate can be used in the environment of 315 degrees for a long time without discoloration, that is to say in the environment of 300 degrees for 120 hours, Baosteel heat-resistant passivation treatment of aluminum zinc plating steel plate color change is lower than aluminum plate and aluminum plating plate.
