Material properties: It has certain ductility and is suitable for simple forming, bending or welding processing.

Typical applications: Home appliance panels, such as air conditioner indoor and outdoor units, computer cases, refrigerator back panels and color-coated substrates, etc.;

Disadvantages of galvanized light sheet

1Welding performance

Due to the increased mechanical properties of galvalume, the surface coating density of the inner base material is better and the manganese content is relatively high. Therefore, galvalume cannot be welded under ordinary welding conditions and can only be connected through rivets and other methods. In terms of welding, hot-dip galvanized steel sheets perform better and there are no welding problems.

2 Applicability of tidal temperature concrete

The composition of galvalume coating contains aluminum, which is prone to chemical reactions in direct contact with acidic, moist concrete. Therefore, it is not very suitable for floor boards.

3 Coating thickness and steel plate thickness restrictions

Most domestic galvanizing production units are modified from hot-dip galvanizing units, and there are certain restrictions on the thickness of galvanized steel sheets. Steel plate thickness is only limited to 0.27 to 2.5. In terms of coating, it can only achieve a minimum of 30 grams per square and a maximum of 220 grams per square.
