As a roof material, metal plate has been used in the construction industry for a hundred years. With the rapid development of the world metallurgical industry in the 1960s, various types of metal plates that can meet the needs of the construction industry were produced, which greatly reduced the material cost of construction. Metal panels are widely used in the construction industry, and aluminum magnesium manganese metal plates are also well known by more and more people.

In recent years, many cases of continuous innovative utilization of aluminum magnesium manganese metal plates can be found in the buildings of many real estate demonstration areas. Its elegant appearance and high cost performance give designers more room to play.

What is aluminum magnesium manganese?

Aluminum magnesium manganese is a kind of roof and exterior wall material with high cost performance. It has many advantages, such as corrosion resistance, beauty, light weight, high strength and easy processing and molding. It is very suitable for the processing of roof crimping and rolling equipment.

In the follow-up, different coating processes should be combined, which can not only bring extraordinary visual effects to the building, but also make the anti-corrosion performance of aluminum alloy itself more excellent.

The reason why aluminum magnesium manganese metal plate material has such excellent durability is that a layer of alumina film will be produced on the surface when the aluminum plate is in contact with the atmosphere, which protects the inner aluminum plate from further corrosion.

This oxide film has good chemical resistance, so it is suitable for industrial buildings, areas with serious air pollution or marine climate.

With the development of modern architecture, the application of metal roof system in architecture has occupied a more and more important position because of its excellent characteristics. It is not only suitable for large-scale public buildings, but also gradually develops towards small and medium-sized buildings and household villas, which has played an important role in the development of modern architecture in the direction of comfort, light, durability, economy and environmental protection.

Characteristics and properties of aluminum magnesium manganese metal plate

Aluminum metal is extracted from nature through electrolysis, and then combined with quantitative elements such as copper, manganese, magnesium, silicon and zinc to form a variety of alloys, which can meet various mechanical and physical properties.

At present, there are nine series of deformed aluminum alloys from 1000 to 9000, which are applied to consumer goods, aerospace, construction, packaging, transportation, electrical equipment and other aspects. It has the following characteristics:

「Excellent characteristics of aluminum magnesium manganese metal plate」

1.Light weight. The density of aluminum is 2.73g/cm3.

2.High strength. High strength can be achieved through composition configuration, processing and heat treatment.

3.Corrosion resistance. With the ability of self rust prevention, the formed oxide layer can prevent metal oxidation and corrosion, and has good acid and alkali resistance.

4.The surface treatment is diverse and beautiful. It can be anodized, electrophoretic, chemically treated, polished and painted.

5.Good plasticity and easy processing.

6.Good conductivity. Non magnetization and low spark sensitivity can prevent electromagnetic interference and reduce flammability in special environment.

7.Easy installation. Aluminum metal can be riveted, welded, glued and other ways to connect.

8.Environmental protection. 100% recyclable.

「Common types of aluminum magnesium manganese metal plates」

The external surface treatment of aluminum materials includes two categories: natural color non earth paint products and paint products:

a.Non painted long products: hammered aluminum alloy plate (irregular pattern), embossed plate (regular pattern is formed by mechanical embossing); Pre passivated alumina surface treatment board. The price of such products is not high, and the surface of such products is not painted.

b.Painting products: according to the painting process, they are divided into: spraying plate products and pre roll coating plate; According to the type of paint, it can be divided into: polyester, polyamide, modified silicone, epoxy resin, fluorocarbon and so on. As far as possible to extend the paint resistance against ultraviolet light aging, in which PVDF coating (fluorocarbon coating) has the most excellent anti-aging properties, it is the most powerful organic compound known to be UV resistant.

「Aluminum magnesium manganese metal panel type」

In order to meet the requirements of building roof, aluminum magnesium manganese alloy roof slab mainly has the following plate types in engineering application.

（1）Straight plate

The rib height of straight plate is generally 65mm, and the commonly used plate widths are 300mm, 400mm and 500mm (Fig. 9). The plate with a width of 300mm is used when the roof load is large; 400mm is commonly used and economical; 500mm is the most economical plate type of the roof panel itself, but the spacing between the lower purlins is small, and appropriate measures need to be taken to prevent plate deformation. See Figure 9 for the details of the plate type.

（2）Curved plate

Arc bending plate includes positive arc plate and reverse arc plate. The plate type is shown in the figure below.

See Table 1 for natural bending parameters of arc bending plate.

See Table 2 for positive bending parameters of arc bending machine.

（3）Sector plate

Sector plate includes straight sector plate, positive sector plate and reverse sector plate, as shown in the figure below:

「Applicable scope of various plate types」

（1）Straight plate: applicable to single slope, double slope and single curved roof with radius greater than natural arc radius;

（2）Positive and negative arc plate: applicable to single curved roof with radius less than natural arc radius;

（3） Fan plate and arc plate: applicable to double curved roof;

（4）Special case: the straight plate is used on the hyperboloid, the curvature of the roof is small, and multiple ridges are allowed on the roof.

See Figure 13 for the construction case of aluminum magnesium manganese alloy roof panel.

「Structural composition of aluminum magnesium manganese roof panel」

Structural drawing of aluminum magnesium manganese roof system

Waterproof breathable layer

A layer of functional membrane laid outside the thermal insulation layer of building envelope is suitable for composite exterior walls and sloping roofs such as curtain wall, profiled steel plate, steel (wood) structure and masonry. By covering the thermal insulation (heat insulation) layer of the enclosure structure, the penetration of water and air into the building is reduced, and at the same time, the enclosure structure and indoor moisture are discharged, so as to effectively avoid the generation of mold and condensation flood in the wall and roof, and ensure the efficiency of thermal insulation (heat insulation) materials, so as to achieve the role of energy conservation and improve the durability of the building.

Moisture barrier

The vapor barrier membrane is used for the inner surface of the wall or roof insulation layer. It is impermeable to steam and can prevent the indoor water vapor from penetrating into the enclosure structure, so as to effectively ensure the thermal insulation performance of the thermal insulation material and the durability of the structure.

Thermal insulation layer

Glass wool felt with thermal conductivity less than or equal to 0.058 and rock wool board with thermal conductivity less than or equal to 0.044 have non combustible combustion performance.

Punched sound-absorbing board

It has excellent effect of absorbing noise and noise.
