Comparison of application advantages of fluorocarbon-coated aluminum-magnesium-manganese plate compared with color steel plate

Fluorocarbon-coated aluminum-magnesium-manganese panel is a high-quality roofing material that has attracted more and more attention from the market. It is gradually replacing color steel tiles with lightning speed and becoming one of the main bodies of the market. Why do customers choose fluorocarbon-coated aluminum-magnesium-manganese panels one after another?

　　1. Durability comparison: Fluorocarbon-coated aluminum-magnesium-manganese plate can form an alumina film with the atmosphere to prevent further corrosion. Used in civil buildings, there is generally a 15-20 year coating quality assurance, and the architectural design service life is more than 50 years. Usually, the product warranty period is 25 years; the color steel plate is easily corroded and rusted under the erosion of humid air and rain and snow, especially the parts of rivets and seams, and leads to fracture accidents.

　　2. Weight comparison: Fluorocarbon-coated aluminum-magnesium-manganese plate is lighter (density is 2730kg/m3); color steel plate is heavier (density is 7850kg/m3).

　　3. Comparison of strength and stiffness: Fluorocarbon-coated aluminum-magnesium-manganese plates have magnesium and manganese content, so they have certain strength and stiffness. However, the internal stress, hardening and strength of aluminum alloy plates have no obvious yield point, which is not as good as that of color steel plates; color steel plates have better strength and stiffness and are not easy to deform.

　　4. Appearance control: Fluorocarbon-coated aluminum-magnesium-manganese sheets can be divided into non-painted such as hammering, embossing, pre-passivated alumina surface treatment, and PVDF, SMP, PE and other paints; color steel sheets can be divided into hot-dip galvanized steel sheets and PVDF, SMP, PE, HDP and other paints.

　　5. Forming: Fluorocarbon-coated aluminum-magnesium-manganese plate has good weldability, high plasticity, high strength and ductility of aluminum alloy in low temperature environment, and good low temperature processing performance; color steel plate is prone to cold brittleness at low temperature.

　　6. Cost-effectiveness: Fluorocarbon-coated aluminum-magnesium-manganese plate is more cost-effective, light in weight, waterproof, easy to bend, and has good three-dimensional effect; color steel plate has lower cost performance, heavier weight, slightly worse water resistance, and strong steel. Arc is slightly worse, and the artistic effect is poor.
