Prepainted 3003 aluminum coil roll

October 10, 2020

Prepainted 3003 aluminum coil roll with aluminum-magnesium-manganese alloy products are a cost-effective roofing and exterior wall material. Aluminum-magnesium-manganese alloy has been widely used in the construction industry, and has played an important role in the development of modern buildings in the direction of comfort, lightness, durability, economy, and environmental protection. AA3003 magnesium aluminum alloy (AlMg1Mn1) is generally recognized as a roofing and exterior wall material with a design service life of more than 50 years due to its moderate structural strength, weather resistance, stain resistance, and easy bending and welding.

The performance features of prepainted 3003 aluminum coil roll are:

1, Durability: Under the erosion of humid air and rain and snow, it forms an aluminum oxide film with the atmosphere to prevent further corrosion.

2, Weight: light weight, density of 2710kg/m3.

3, Strength and stiffness: aluminum alloy has manganese and magnesium content, so it has certain strength and stiffness.

4, Appearance: the prepainted 3003 aluminum coil can be divided into non-painting (hammer embossing, pre-passivation alumina surface treatment) and painting (PVDF SMP PE).

5, Lightning protection performance: The thickness is generally 0.7mm and 0.9mm, which can be directly used as lightning protection air-termination device (Code for Design of Building Lightning Protection” GB50057) to avoid perforation in the roof.

6, Fire protection: Low melting point (660°C). In the event of a fire, the roof is easily burned through, causing the fire to spread outwards instead of inward and laterally, which helps firefighters to reach the fire hose from the top to fight the fire.
