Compared with the weight of color steel tiles, it is only 3/1 of the color steel tiles, which effectively reduces the weight of the building. Although aluminum-magnesium-manganese roof panels are light in weight, their strength is no worse than that of color steel tiles. The manganese element contained in the material effectively improves its own strength.
Conductivity
The electrical conductivity of the roof is very good. With the mature lightning protection system design, the roof panel can be used as an air terminal alone, without the need for lightning protection strips. Aluminum-magnesium-manganese alloy roof panels can also carry lightning rod effects to form a safe multiple lightning protection system.
Corrosion resistance
The surface coating increases the resistance to acid rain and industrial corrosion. The aluminum-magnesium-manganese alloy roof panels are also unresponsive to ultraviolet rays, resistant to microorganisms, and not easy to age.
Finally, we must not talk about the economics of aluminum-magnesium-manganese roof panels: although they are more expensive than color steel tiles, color steel tiles will rot after many years of use, and the purchase price is lower, while aluminum-magnesium-manganese roof panels are corrosion-resistant. The purchase price is higher and 80% can be recycled.
