Classification of weather-resistant steel plates: Weather-resistant steel plates are divided into high weather-resistant steel plates [higher P content: 0.07 to 0.15wt percentage] and welded weather-resistant steel plates (lower P content: ≤0.04wt percentage). These two materials are added with (GNH) and (NH) after the steel number of the carbon structural steel plate.
Weather-resistant steel plate is a steel plate that is resistant to weather corrosion. The source is Corten steel plate in North America. It belongs to the low-alloy steel plate series and is a material between ordinary steel and stainless steel plates. Weather-resistant steel plate is made of ordinary Q235 series carbon steel with some copper and nickel anti-corrosion alloy elements added. Weather-resistant steel plate has unique characteristics such as strength, plasticity, shape, laser, corrosion resistance and high temperature resistance. Its resistance to weather corrosion is two to eight times that of ordinary Q235 carbon steel, its coating corrosion resistance is two to ten times that of ordinary Q235 carbon steel, and it has strong rust resistance, making the products made with super Strong corrosion resistance extends life, can reduce thickness, save costs and labor, and requires no maintenance.
Rust art surface treatment: The surface rust treatment of weather-resistant steel plates is to use chemical rust potion (Huajian Weather-resistant Brand) to dissolve the oxide scale on the surface of the steel plate, allowing it to produce a uniform rust layer on the surface. The rust layer has a protective effect and can also be certain It can inhibit the initial rust phenomenon. It takes 1-2 years for the latest weather-resistant steel plates to form a stable and dense rust layer in South China, and 5-6 years or even longer in some relatively dry areas. Therefore, most of the people on the market use Huajian weather-resistant rust accelerator to quickly promote the rust of steel plates. You can also choose other brands of rust potions and construction methods.
