Advantages of weathering steel plate
1. Green and environmental protection
There is no need for initial painting, which can reduce the use of fireproof coatings and fireproof coatings, thereby reducing pollution, shortening the construction period, reducing costs and reducing maintenance. It is an economical steel with "green environmental protection" and sustainable development.
2. High visual expression The weather-resistant steel plate will change over time, and its color brightness and saturation are higher than those of general structure materials, so it is easier to stand out against the background of garden plants.
3. Strong shape shaping ability Weather-resistant steel plates are relatively easy to shape into rich and varied shapes, and can maintain excellent integrity.
4. Good space definition
The space is clearly and accurately separated by thin weather-resistant steel plates, making the site concise and clear.
Disadvantages of weathering steel plate
1. Corrosion of welding points
The oxidation rate of the solder joint must be the same as that of other materials, which requires special welding materials and techniques.
2. Waterlogged corrosion
The weather-resistant steel plate is not a stainless steel plate. If there is water in the recess of the weather-resistant steel, the corrosion rate will be faster, so drainage must be done well.
3. Salt air environment
Weathering steel plates are sensitive to salt-rich air environments, and in such environments, the surface protective film may not be able to prevent further internal oxidation.
4. Fading
The rust layer on the surface of the weathering steel plate can make the surface of objects near it rusty.
5. Maintenance processing
Anti-rust and various patterns and colors need to be treated, and the price of many treatments is relatively expensive.
