In what ways is aluminum magnesium manganese plate better than color steel plate?

aluminum magnesium manganese plate

1.Durability comparison

Aluminum magnesium manganese alloy can form an alumina film with the atmosphere to prevent further corrosion, and is generally used in civil buildings with a coating warranty of 15-20 years. The design life of the building is more than 50 years. The color steel plate is easy to corrodes and rusts under the erosion of humid air and rain and snow water, resulting in fracture accidents, especially in the parts of rivets and joints.

2.Weight comparison

Aluminum magnesium manganese alloy light weight (density of 2730 kg/m2); Color steel plate weight is relatively heavy (density 7850 kg/m2)

3.the strength and stiffness are different

Although there is no obvious yield point in the strength and hardness of aluminum in the aluminum plate, it has a certain strength and stiffness because it also contains magnesium and manganese. As for the color steel plate, its strength and stiffness will be better than the former, and it is not easy to deformation.

Colored steel plate

4.lightning protection is different

Usually these two kinds of building materials are used in the external wall, so its lightning protection also needs to be considered, but the thickness of aluminum magnesium manganese plate is generally 0.7-0.9㎜, which can play a good lightning protection role; The thickness of the color steel plate is only 0.5㎜ steel plate, lightning protection is not as good as the former, and another shelf is needed to prevent it.

5.Fire safety

Aluminum magnesium manganese alloys have a low melting point (660 degrees Celsius). The high temperature resistance is poor, and the strength is rapidly lost above 150 degrees. In the event of a fire, the roof is easy to burn through, so that the fire spreads outwards, rather than outwards, which helps firefighters to extend the fire hose from the top to extinguish the fire; Color plate steel has a high melting point (1515 degrees Celsius).

6.forming

Aluminum magnesium manganese alloy has good plasticity, low temperature environment, aluminum alloy strength and ductility can be improved, has a good low temperature performance; Color steel plates are prone to cold brittleness at low temperatures.

7.Cost performance

Aluminum magnesium manganese alloy plate is light, waterproof, easy to bend arc, good stereoscopic visual effect; Color steel plate is heavy, slightly poor waterproof, strong steel bending slightly poor, artistic effect is not good.
