1. Different durability. Aluminum magnesium manganese plate has good corrosion protection effect, because it can form a layer of aluminum oxide film with the atmosphere, and its service life in the construction industry will also become longer. However, the color steel plate is particularly prone to corrosion and rusting and then fracture in the wet environment.
2. Different strength and stiffness. Density of color steel plate 7.85kg/m ³， The density of aluminum magnesium manganese board is 2.73kg/m ³， Aluminum magnesium manganese plate contains magnesium and manganese elements, and has certain strength and rigidity. However, the hardness and strength of aluminum alloy have no obvious yield point. On the contrary, the strength and rigidity of color steel plate are good, and it is not easy to deform.
3. The lightning protection performance is also different. The former is generally 0.7 mm and 0.9 mm thick, which can be directly used as lightning arrester, while the color steel plate is generally 0.5 mm steel plate, which can not be directly used as lightning arrester, and requires additional lightning arrester.
4. There are also differences in safety and fire protection. Aluminum magnesium manganese plate has a low melting point and poor high temperature resistance. It is easy to burn through in case of fire, and the fire will spread outward, which is also convenient for firefighters to put out fire, but the melting point of color steel plate is very high.
5. Price difference: the price of aluminum, magnesium and manganese is relatively high. The current market price of aluminum, magnesium and manganese is 30000 yuan per ton, and the color steel plate is about 8000 yuan per ton. The price difference is still a little far.
6. Both are the properties of steel coils. Both color steel plate and aluminum magnesium manganese are in the form of color steel coil.
7. Purpose. Aluminum magnesium manganese plate is mainly used as roof, such as 430/840/900/750/780. Color steel plate has a wide range of uses. It is the preferred material for both single tile and composite plate.
8. The commonly used specifications of aluminum magnesium manganese plate thickness: 0.5-1.2mm, width: within 1250m. Common specifications: 1000/1200/12500
Common specifications of color steel plate thickness: from 0.3-2.0mm to 1250mm wide. Common width: 1000/1200/1070mm
Comparatively speaking, the cost performance ratio is also very different. The former has high cost performance, light quality, good waterproof function, and good stereo vision, while the color steel plate has poor waterproof performance, slightly poor arc bending, and the artistic effect is not as good as the aluminum magnesium manganese alloy roof.
