Comparison of aluminum magnesium manganese alloy roofing plate and color steel plate
Color steel plate refers to color coated steel plate, color coated steel plate is a kind of steel plate with organic coating.
Aluminum magnesium manganese plate is a very cost-effective roofing, exterior wall material. Aluminum alloy has been widely used in the construction industry, and has played an important role in the development of modern buildings to the direction of comfort, light weight, durability, economy and environmental protection. AA3004 aluminum magnesium manganese alloy due to moderate structural strength, weather resistance, stain resistance, easy bending welding processing and other advantages, is generally recognized as a building design life of more than 50 years of roof, exterior wall materials; According to the architectural design of Marine climate, 5052 Marine grade aluminum alloy material with stronger corrosion resistance can be selected.
Color steel plate refers to color coated steel plate, color coated steel plate is a kind of steel plate with organic coating. Color steel plate is divided into single board, color steel composite board, floor bearing board, etc. It is widely used in the wall and roof of large public buildings, public workshops, movable board houses, and integrated houses.

Characteristics of aluminum, magnesium and manganese | ||
durability | Form an alumina film with the atmosphere to prevent corrosion. | It is easy to corrod and rust under the erosion of humid air and rain, snow and water, especially the joint part. |
Light weight (density 2700kg/m3) | Relative weight (density 7850kg/m3) | Relative weight (density 7850kg/m3) |
Aluminum alloy has magnesium and manganese content, so it has a certain strength and steel | Good strength and steel | Good strength and steel |
Can be divided into non-painted (hammer, embossed, pre-passivated alumina surface treatment, etc.) and painted (PVDF, SMP, PE, PVC skin film, etc.) | Paint (PVDF, SMP, PE, PVC film, etc.) | Paint (PVDF, SMP, PE, PVC film, etc.) |
Lightning protection performance | The thickness is generally 0.7mm and 0.9mm, which can be directly used as a lightning protection flash device (national specification "Building lightning Protection Design Code" GB050057) to avoid perforating the roof. | Generally 0.5mm aluminum plated zinc and galvanized plate, can not be directly used as lightning protection flash (such as lightning rod) |
The melting point is low (660 degrees Celsius), and in the event of a fire, the roof is easy to burn through, so that the fire spreads outwards, rather than outwards, helping firefighters to extend into the fire hose from the top. | High melting point of steel (1515 degrees Celsius) | High melting point of steel (1515 degrees Celsius) |
