Properties of coated steel sheets for construction

To the ultimate owner of a building, sex and longevity are important. For design units, service life, carrying capacity, and appearance are more important. For the forming processors of building walls and roofs, the processability (surface hardness, wear resistance, plate shape and steel plate strength) of coated steel plates is the primary requirement.
Building (roof panels and exterior wall panels) itself can be divided into performance (impact, wind pressure and fire resistance), residential performance (waterproof, heat insulation and sound insulation), durability (pollution, weather resistance) and appearance retention), production processability (economy, easy processing, easy maintenance and repair).
The coated steel plate is composed of a substrate and a colored film. We first have to consider the substrate and film thickness. Because from the perspective of affecting the service time of the coated steel plate, the thickness of the substrate is very important.
The color film layer is considered for the durability and corrosion resistance of the building. Different uses can increase its service life by choosing different coatings, color films and thicknesses.
There are two common coatings for steel sheets for construction: hot-dip galvanized and hot-dip galvanized. For the coating, the application fields of the two substrates are not very different. In a relatively acidic environment, the galvanized substrate is a better choice. For use in humid and alkaline environments, the advantages of notch corrosion of galvanized substrates are reflected.
With the massive construction of commercial high-rise buildings, high-rise buildings, stadiums, and exhibition centers, this will provide market demand and development space for the future coated steel plate market.
