Color steel plate is a good building material with a wide range of uses and is deeply loved by people. So what quality issues may arise during the production, transportation, installation, and use of Jinan color steel plates? The following editor will analyze and analyze for you:
1. Poor surface quality: Defects such as dents, scratches, and spots appear on the surface of the color steel plate, which affects its aesthetics and service life.
2. Uneven thickness: Uneven thickness of color steel plates during production can lead to misalignment or imbalance during installation.
3. Bending deformation: During transportation or installation, colored steel plates may bend and deform due to excessive force, affecting their use.
4. Rust: The surface of the color steel plate is not treated with anti-corrosion or improper anti-corrosion treatment, which is prone to moisture and rust, affecting its service life.
5. Poor interface sealing: The connection of the color steel plate is not properly sealed, which can easily cause water and air leakage.
6. Poor corrosion resistance: The coating used for color steel plates is not corrosion-resistant, which may cause problems such as rust and paint peeling on the steel plates.
7. Insufficient hardness: The color steel plate has insufficient strength and is prone to deformation, cracks, and other problems.
In addition, color steel plate is a type of plate produced after multiple treatments, such as cold rolled steel strip on continuous production lines. When designing the plate, the manufacturer has multiple colors according to the needs of different users. The choice of color is mainly based on the appropriate degree between the owner's preferences and the environment.
However, from the perspective of technology, light color paint has more room to choose, and some inorganic pigments with better durability can be selected. Moreover, this kind of paint has strong heat reflection, and the temperature of the coating itself is relatively low in summer, which is conducive to the durability of the coating. Even if the color changes or becomes powdery, the contrast between the light color and the original color is very small, and the impact on the appearance is not significant.
However, organic colors are widely used in dark colors, which are prone to fading when exposed to ultraviolet radiation. For color steel plates, the thermal expansion rates of coatings and plates are generally different, especially the linear expansion coefficients of metal substrates and organic coatings. When the environmental temperature changes, the interface between the substrate and the coating will expand or contract. If not released correctly, the coating will rupture.
That's all for the explanation of quality issues that may occur during the use of color steel plates. We hope to provide you with good help. If you need any help, you can contact our company http://www.cworksmarketing.com 。
