Understand the main characteristics of aluminum magnesium manganese aluminum plate.

As a widely used metal roofing material, aluminum magnesium manganese aluminum plate has the following main characteristics:

1. The density is 2.7, the melting point is 658, the linear expansion coefficient is 0.0000023 at the temperature of 20 ~ 100 degrees, the cracking load coefficient is 8 ~ 12kg/mm2 (depending on the hardness of the material), the elongation is 10 ~ 40%, and the thickness is 0.7～1.2mm. When aluminum corrugated plate is used, the thickness can be reduced to 0.6mm, and the fixing method can be selected by welding besides crimping and riveting.

2. The service life is relatively long.

In recent years, the surface of aluminum siding used in building exterior walls is generally coated with fluorocarbon resin, which generally has strong adhesion, strong aging resistance and weather resistance, and can be used for 20 years in general.

At present, many manufacturers in our country use fluorocarbon resin KYNAR-500 to produce, and the performance of coating paint is usually higher than that of cold coating. For indoor level, aluminum siding coated with polyurethane and polyester can be cited. The appearance of Al-Mg-Mn aluminum curtain wall can generally withstand long-term wind and sun exposure, and it will not change color, and the impact of natural wear is relatively small. In this regard, in the specific construction, the construction units should pay enough attention.

3. Economy: In terms of price, Al-Mg-Mn plate with high vertical edge is more expensive than Al-Mg-Mn plate with low vertical edge, which is mainly caused by its different feed width.

4. Aesthetics: From the appearance, the finished aluminum magnesium manganese plate with low vertical edge is more beautiful than that with high vertical edge.

5. Water resistance: In terms of water resistance, the Al-Mg-Mn plate with high vertical edge has more advantages, which depends on the height of ribs, and the plate with high vertical edge is more difficult to penetrate rainwater.

6. Availability: Under normal circumstances, they are all used for roofs. However, in the absence of specific requirements, Al-Mg-Mn roof panels with low vertical edges are more used in private villas, while Al-Mg-Mn aluminum panels with high vertical edges are more used in stadiums and other venues.

What are the advantages of Al-Mg-Mn-Al reinforcement system?

This chapter introduces a ribbed reinforcement system of Al-Mg-Mn-Al plate with locking joints. The reinforcement measure of this system is to apply wind-resistant clamps to the supports of Al-Mg-Mn roof panels. Compared with the traditional technology, it has the following obvious advantages:

Firstly, compared with the traditional wind-resistant reinforcement measures, the plate-rib reinforcement system has stronger wind-resistant bearing capacity.

The traditional air clips can only strengthen the locking joints of aluminum-magnesium-manganese roof panels, and cannot provide greater out-of-plane stiffness for the flat web area of aluminum-magnesium-manganese roof panels. While strengthening the locking joint, the plate rib reinforcement system can provide the out-of-plane stiffness of the flat web area of the aluminum-magnesium-manganese roof panel under the condition of wind absorption load by setting the stiffening rib or stiffening rib above its flat web position, so as to reduce the deformation of the locked joint roof panel and strengthen the wind-resistant bearing capacity of the aluminum-magnesium-manganese roof panel.

Secondly, the layout of plate-rib reinforcement system is more flexible than the traditional wind clamp reinforcement measures.

Most of the traditional wind-resistant fixtures can only be applied to fixed supporting positions. If they are applied to non-supporting positions, the reinforcement results will be greatly weakened, while the plate rib reinforcement system can be applied to fixed supporting positions or non-supporting positions, which can achieve better results in strengthening the wind-resistant bearing capacity of aluminum magnesium manganese aluminum plates.

Thirdly, compared with the traditional wind clamp reinforcement measures, the plate-rib reinforcement system has better ability to release deformation.

The application of traditional air clips will weaken the longitudinal expansion and deformation capacity of the aluminum-magnesium-manganese roof panel at the support more or less, and the plate rib reinforcement system has ring locks with similar shapes to the two ends of the aluminum-magnesium-manganese roof panel, which will not affect the longitudinal expansion and deformation capacity of the aluminum-magnesium-manganese roof panel.

Fourthly, compared with the traditional wind-clip reinforcement measures, the slab-rib reinforcement system has the advantage of maintaining the inherent architectural function of the aluminum-magnesium-manganese roof, which will not destroy the architectural function of the aluminum-magnesium-manganese roof and avoid the influence of wind-clip on the architectural function.

Fifth, the simpler the plate-rib reinforcement system is, the simpler the construction method is.

Aluminum-magnesium-manganese aluminum plate stiffener system is convenient to process. In the construction process, as long as the manual fixture can complete the whole site construction process, the installation is simple and the construction period is short.
