Metal Roofing Coil Stock

August 7, 2023

Aluminum-magnesium-manganese metal roofing coil stock is a cost effective roofing and exterior wall material. Aluminum coil stock is widely used in the construction industry and has played an important role in the development of modern architecture towards comfort, lightweight, durability, economy, and environmental friendliness. AA3004 aluminum-magnesium-manganese alloy is widely recognized as a roofing and exterior wall material with a design life of over 50 years, due to its moderate structural strength, weather resistance, stain resistance, and ease of bending, welding, and processing. For architectural designs in marine climates, the more corrosion-resistant 5052 marine grade aluminum alloy can be chosen.
