Aluminum Roof Coil
Aluminum roofing coils generally refer to raw or coated aluminum alloy coils used for various roofs. For example, typical ones include EN AW 5005, 3105, 3005, 3003, 3004, 5754 aluminum coils, etc. Aluminum is known to have outstanding durability and is lighter and easier to work with than other materials. In addition, due to the addition of Mn, Mg and other alloying elements, it has even better performance. For example, 3105 alloy has better surface treatment capabilities than other series. And 5754 has the highest corrosion resistance, etc.
Aluminum roofing coil alloys and advantages
3105 Aluminum Roof Coil: In fact, it is essentially a 98% aluminum alloy. In fact, the strength of alloys 1100 and 3003 is increased by small additions. 3105 aluminum also belongs to the Al-Mn series of non-heat-treatable alloys. Therefore, it is improved by cold working. In addition, 3105 aluminum coils also have good processability, formability, weldability, and corrosion resistance. Especially surface treatments such as coloring.
