Scientific material selection standards for color-coated steel in areas with severe sandstorms

In areas with severe sandstorms, the material selection standards for color-coated steel need to be more stringent to ensure their durability and stability.
Here are some key scientific material selection criteria:

Coating material:
Corrosion resistance: Paints with strong corrosion resistance should be used, such as SMP silicon-modified polyester, etc. This type of paint can effectively resist the erosion of the surface by wind and sand.
Adhesion: There should be good adhesion between the coating and the substrate to avoid the friction of wind and sand causing the coating to peel off.
Substrate selection:
Galvanized steel plate: Choose high-anti-corrosion galvanized or galvanized steel plate as the base material to increase its resistance to sandstorms and corrosion.
Base material thickness: According to the requirements of the use environment, select a steel plate of appropriate thickness to improve the ability to resist wind and sand impact.

Surface treatment:
Surface smoothness: Ensure the surface of the substrate is smooth and flat, and reduce the adhesion of wind and sand to reduce wear.
Anti-fouling performance: Choosing materials with good anti-fouling properties can reduce the adhesion of wind and sand and reduce the frequency of cleaning.
Color and gloss:
Choose colors with strong weather resistance to avoid fading due to sun exposure, and at the same time, the gloss should be moderate to reduce the adhesion of sand and dust.
Design considerations:
Structural design: The design of the panels is reasonably optimized according to climate conditions to ensure that they will not be damaged in strong winds and sandstorms.
Maintenance and inspection:
Regularly check the coating and substrate status of color-coated steel, and perform timely maintenance and repairs to extend their service life.

Application industries: Northwest and other areas with severe sandstorms,
Industry characteristics: In the Xinjiang region of my country, due to the large desert area and severe sandstorms all year round, the coating surface of color-coated steel is more destructive.
Material selection criteria: SMP silicon-modified polyester color steel plate is more suitable for areas with severe sandstorms, including mining and other industries, due to its coating hardness, wear resistance, non-pulverization, durability and other characteristics. The substrate should be a galvanized sheet with a double-sided zinc layer of not less than 120 grams/square meter, and the front coating thickness should not be less than 20um.
In summary, in environments with severe wind and sand, it is crucial to choose color-coated steel that meet the above standards to ensure their performance and durability.
