With the modern building are gradually advocating energy saving, environmental protection building materials, step by step to eliminate the traditional building materials, then as a new type of roofing metal material on the market - aluminum magnesium manganese metal plate and color steel plate, which one is better between the two?

Aluminum magnesium manganese alloy roof panel is a new type of roof panel, aluminum magnesium manganese alloy in the construction industry is widely used, for the modern building to comfortable, light, durable, economic, environmental protection and other directions played an important role in the development. Due to its moderate structural strength, weather resistance, stain resistance, easy to bend and weld processing and other advantages, it is generally recognized as a roofing and exterior wall material with a service life of more than 50 years for architectural design.

The use of metal sheets as roofing materials has a history of hundreds of years, and the large number of metal materials used as roofing materials is mainly due to the rapid development of the world metallurgical industry since the 1960s, which can produce a variety of specifications and meet the quality requirements of metal sheets, and reduce the cost.

Metal roofing materials mainly include galvanized steel, stainless steel, aluminum, copper, zinc-copper-titanium and pure titanium. The advantages of metal sheet roofing are simple construction, fast, good waterproof performance, and reusable. In addition to being resistant to the highest and lowest temperatures that can be generated by the earth's climate, it is rarely affected by the climate and the stresses caused by roof deformation when used as a roofing material, and one can apply various colors of paint according to the situation.

In terms of strength and steel: Aluminum-magnesium-manganese alloy has magnesium and manganese content in the aluminum alloy, so it has certain strength and stiffness. However, the internal stress and hardening and strength of aluminum alloy plate have no obvious yield point, which is not as good as color steel plate; color steel plate has better strength and stiffness and is not easy to deform.

Safety firefighting: aluminum-magnesium-manganese alloy has low melting point (660 degrees Celsius). High temperature resistance is poor; color steel plate steel melting point is high (1515 degrees Celsius), high temperature resistance is better.

Comprehensive strength and safety performance, color steel plate is better than a life.
