Shandong aluminum-magnesium-manganese plate manufacturers: aluminum-magnesium-manganese plate is what material?

Shandong aluminum-magnesium-manganese plate manufacturers said, aluminum-magnesium-manganese plate is a new type of roofing material, has been widely used in the construction industry, in the modern building towards the direction of comfort, lightweight, durable, economic and environmental protection to play an important role in the development.

Shandong aluminum-magnesium-manganese plate manufacturers said, aluminum-magnesium-manganese roofing panels, also known as aluminum-magnesium-manganese plate, is a kind of alloy panel made of aluminum, magnesium and manganese. Al-Mg-Mn plate has medium structural strength and strong plasticity. It can be made into Al-Mg-Mn fan panel, arc panel and other shaped panels, which can meet all kinds of roofing needs (such as hyperbolic, curved surface, spherical, arc, cone, etc.) and realize the shaped structure that cannot be solved by the traditional roofing tiles.

Aluminum-magnesium-manganese sheet is a cost-effective roofing and exterior wall material with the advantages of corrosion resistance, aesthetics, light weight, high strength, easy processing and molding, etc. It is very suitable for roof crimping and rolling equipment. Subsequently, different coating processes should be coordinated to bring extraordinary visual effects to the building, while the corrosion resistance of the aluminum alloy itself will become even better.

In what aspects is Al-Mg-Mn plate superior to color steel plate?

1、 Comparison of durability: Al-Mg-Mn alloy can form aluminum oxide film with the atmosphere to prevent further corrosion. Generally speaking, when used in civil buildings, the coating warranty is 15-20 years. The building is designed for a service life of more than 50 years. Color steel plate is easy to corrode and rust under the erosion of humid air, rain and snow, leading to fracture accidents, especially rivets and joint parts.

2, weight comparison: aluminum-magnesium manganese alloy is light (density of 2730 kg/m2); color steel plate is heavier (density of 7850 kg/m2)

3, strength and stiffness are different. Shandong aluminum-magnesium-manganese plate manufacturers said, although the strength and hardness of aluminum in aluminum-magnesium-manganese plate has no obvious yield point, but it also contains magnesium and manganese, so it has a certain strength and stiffness. As for the color steel plate, its strength and stiffness will be better than the former, not easy to deform.

4, lightning protection is different. Usually, these two building materials are mostly used for external walls, so their lightning protection also needs to be considered. But the thickness of aluminum-magnesium-manganese plate is generally in 0.7-0.9 mm, can play a good role in lightning protection; color steel plate is only 0.5 mm thick, its lightning performance is not as good as the former, so you need to set up another shelf for protection.

5, safety and fire prevention: aluminum-magnesium-manganese alloy melting point is low (660 ℃). High temperature resistance is poor, when the temperature exceeds 150 ℃, the strength is rapidly lost. Once a fire occurs, the roof is easy to burn through, making the fire spread outward rather than inward and horizontally, which helps firefighters extend fire hoses from the top to extinguish the fire; color steel plate melting point is high (1515 ℃).

6, Forming: Al-Mg-Mn alloy has good plasticity. In the low-temperature environment, the strength and ductility of aluminum alloy is improved, with good low-temperature working performance; color steel plate is easy to cold embrittlement at low temperatures.

7, cost-effective: aluminum-magnesium-manganese alloy sheet light, waterproof, easy to bend the arc, three-dimensional visual effect; color steel plate is heavier, waterproof is slightly worse, rigidity, arc bending is slightly worse, the artistic effect is worse.
