What kind of paint is used to spray paint galvanized sheet?

Galvanized sheet above the need to paint, in order to play the anti-corrosion effect, there are many kinds of paint on the market, many friends do not understand. So what kind of paint is used to spray paint galvanized sheet? What are the advantages of galvanized sheet?

What kind of paint is used to spray paint galvanized sheet

Galvanized sheet surface paint is usually used to use special metal paint, in order to achieve better adhesion and protection. It is recommended to choose epoxy primer, which has good adhesion and protection. It is recommended to choose epoxy primer, which has good adhesion and protection. If the use of ordinary paint, such as polyurethane paint, acrylic paint, etc., will not be able to attach to the metal surface, difficult to attach to the surface of the plate, easy to fall off the paint, and can not achieve the effect of anti-corrosion decoration

What are the advantages of galvanized sheet

1. processing performance

Galvanized steel plate has good processing properties, and can be bent, stamped and other forms according to processing needs. To meet different processing needs.

2. Corrosion resistance

In the case of the same thickness and coating, the galvanized steel plate can be combined with other plates, because the galvanized plate has strong anti-corrosion performance, the use is also 2-6 times that of ordinary profiles.

3. light, heat resistance

Galvanized sheet has good heat and light, and ordinary profiles have temperature requirements of not more than 230°C, easy to change color, and galvanized sheet even in a high temperature environment, will not produce any color change

4. Mechanical properties

Galvanized sheet has good mechanical properties, and can resist tensile yield. The normal strength of profiles is generally 140-300 bars, and the tensile strength is only 200-330 bars, but the zinc yield strength of galvanized sheets can reach 230-400 bars, the strength can be 230-550 bars, and the elongation is about 15-45 bars
