Aluminum roofing sheet with Mn and Mg
There are a new type of aluminum roofing sheet in the market, that is Aluminum-magnesium-manganese alloy roofing sheet. Al-Mn-Mg alloy has been widely used in the construction industry and has played an important role for the development of modern architecture in the aspects of comfort, lightness, durability, economy and environmental protection. 3004 and 3005 Aluminum-magnesium-manganese alloy (Al-Mg-Mn) is universally accepted as the roofing and curtain wall materials with the service life of 30 years or more in architectural design because of its moderate structural strength, weather resistance, stain resistance and easy bending features. Due to the marine climate, in architectural design, the 5052 ship-class aluminum alloy material can be choosed because of its better corrosion-resistant properties. The physical properties of aluminum roofing sheet with Mn and Mg alloys are: 1, Light texture: with the same thickness, aluminum roofing sheet is lighter than the weight of many ot...
