AL-MG-MN Prepainted Aluminum Sheet Advantages

Aluminum magnesium manganese roofing (Al-Mg-Mn IBR roofing) is an extremely cost-effective roofing material. Due to its advantages of corrosion resistance, beautiful appearance, light weight, high strength and easy molding, it has a service life of up to 50 years and is widely used in airport terminals, aircraft maintenance hangars, stations and major transportation hubs, etc. It is light, weatherable, stain-resistant, and easy to be welded, and its structure strength is moderate.

Aluminum-magnesium-manganese alloy sheet metal aluminum sheet is divided into 10 series, among which the aluminum material for construction is mainly 3000 series, such as AA3003, AA3004, AA3005, the outer surface treatment of aluminum material includes: unpainted products and painted products. :
a. Non-painted products: hammered aluminum alloy plate (irregular pattern), embossed plate (regular pattern formed by mechanical embossing); pre-passivated alumina surface treatment plate. This kind of product is not painted on the surface of the board, the appearance of the surface is not high, and the price is low.
b. Painted products: according to the coating process, it is divided into: sprayed board products and pre-rolled coated boards;
According to the type of paint, it can be divided into: polyester, polyamide, modified silicone, epoxy resin, fluorocarbon, etc.

Features of aluminum magnesium manganese roofing:
1) Corrosion resistant. Aluminum metal is a reliable and durable outdoor building material. It has self-anti-rust ability. In the natural environment, a thin and dense oxide layer can be formed on its surface to prevent the metal from oxidizing and rusting in K air. It also has resistance to various acids. The ability to erode.
2) Light weight. The density of aluminum is 2.73g/m3, only 1/3 of that of steel.
3) High strength. Through aluminum alloy configuration, processing and heat treatment methods can achieve high strength, and even the structure of large passenger aircraft can be built.
4) Durable. Non-magnetization and low spark sensitivity, can prevent electromagnetic interference and reduce flammability in special environments.
5) Beautiful appearance. Extrudable profiles, drawn, rolled, punched, spun, rolled, cast and forged. Aluminum sheets can be rolled to various thicknesses, even extremely thin aluminum foils.
6) Easy to form. Aluminum metal can be connected by riveting, welding, gluing, etc.
7) Recyclable. Aluminum recycling has a high value, and the long-term use cost is relatively economical, which plays a positive role in saving natural resources.
