Aluminum magnesium manganese alloy roof panel is a new type of roof panel. Aluminum magnesium manganese alloy is widely used in the construction industry and plays an important role in the development of modern buildings in the direction of comfort, light
weight, durability, economy and environmental protection. 3004 / 3005 aluminum magnesium manganese alloy (almg1mn1) is widely recognized as roof and exterior wall materials with a service life of more than 50 years in architectural design due to its
moderate structural strength, weather resistance, stain resistance and easy bending and welding processing; According to the architectural design of marine climate, 5052 marine aluminum alloy materials with stronger corrosion resistance can be selected,
and 3003 / 3004 commonly used materials for general roof panels can be selected.
Single edge locking roof system: because the rib height of this system is 65mm, there is no nail on the panel. It fully surrounds the edge locking mode, which is quite in place in terms of drainage and waterproof, and the shape conforms to the characteristics
of aluminum. It has beautiful appearance and is generally used in large landmark buildings such as gymnasium, convention and Exhibition Center, airport, station and so on.
Processing and production technology of aluminum magnesium manganese plate
The external surface treatment of aluminum includes two categories: natural color non painted products and painted products: 1. Non painted products: Hammer aluminum alloy plate (irregular pattern) and embossed plate (regular pattern is formed by mechanical
embossing); Pre passivated alumina surface treatment board. Such products are not painted on the plate surface, have low requirements for surface appearance and low price. 2. Painting products: according to the coating 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, polyurethane, polyamide, modified silicone, epoxy resin, fluorocarbon and so on. As far as possible to extend the paint resistance
against ultraviolet light aging, in which the PVDF coating (fluorocarbon coating) has the best anti-aging properties, it is the most known anti ultraviolet organic compound known to human beings before. According to different quality requirements, fluorocarbon
coated aluminum plate adopts horizontal automatic two coating and two baking, three coating and three baking and four coating and four baking roller coating processes respectively. The resin content of the precoated PVDF coating varies from 70% to 80%.
It is roller coated by chemical pretreatment, initial coating, fine coating and other processes on the high-speed continuous unit. The front coating is generally 25% μ m. Back coated with anti-corrosion paint.
Metal roofing materials mainly include
galvanized steel plate, stainless steel plate, aluminum alloy plate, copper plate, zinc copper titanium composite plate and pure titanium plate. The advantages of metal plate roof are simple construction, fast speed, good waterproof performance and reusable.
In addition to being able to withstand the highest and lowest temperatures produced by the earth's climate, when used as roof materials, it is rarely affected by the stress caused by climate and roof deformation. People can also paint various colors according
to the situation.
