Why is color coated steel increasingly being replaced by color coated aluminum?
Nov 12,2021
Due to the anti-corrosion function of pre-painted aluminum plate, it has replaced pre-painted steel plate in more and more fields. So, what are the advantages of pre-painted aluminum plates, which are favored by building maintenance systems?
First, the durability is good, and the aluminum plate has anti-corrosion function
Aluminum molecules combine with oxygen in the air to form an alumina film, which covers the surface of the aluminum plate, which can prevent the further oxidation of the aluminum plate, form a natural protective film, and have its own anti-corrosion function.
Second, light weight, reduce the load of the support structure
The density of alloy aluminum is 2.73, which is one-third of the steel plate, and its light weight greatly reduces the load of the supporting structure, and is widely used in airports, stations, stadiums and other large-span construction fields.
Third, high strength, strong rigidity
Due to the addition of metal components such as magnesium and manganese to the alloy aluminum plate, the strength and rigidity of the aluminum plate are greatly enhanced through the composition configuration, and its load-bearing performance is improved.
Fourth, good plasticity, easy to process
It can be bent into straight plate, inner arc, outer arc, fan, and can adapt to various shapes of the roof - spherical, arc, fan, etc., to meet the designer's design concept to the greatest extent.
5. The type and color of coating can be selected according to needs
The surface of the aluminum plate can be painted with different colors and coating types according to the architectural style and design requirements, which solves the problem of cost and design age, and can fully display the artistic effect of the building.
6. Recyclable and high value
After the ordinary color steel plate is corroded, it can only be sold for a few cents a kilogram, and when the color coated aluminum plate is recycled, the price can reach 8.5-9.5 folds of the aluminum plate, and the recycling value is significantly higher than that of the ordinary color steel plate.
