How to choose materials reasonably?
Reasonable material selection can not only meet the usage requirements, but also greatly reduce costs. If the material selection is improper, the result may be that the material performance exceeds the usage requirements, causing unnecessary waste, or it may not meet the usage requirements, resulting in degradation or inability to use. Therefore, users should attach great importance to the importance of reasonable material selection, and if necessary, please contact us.
The selection of color coated boards mainly refers to the selection of mechanical properties, substrate type (coating type) and coating weight, front coating performance, and back coating performance. Usage, environmental corrosiveness, service life, durability, processing method, and degree of deformation are important factors to consider when selecting materials.
·Selection of mechanical properties, substrate type, and coating weight
The mechanical properties are mainly selected based on factors such as purpose, processing method, and degree of deformation. For example, the roof panel of a building is usually not load-bearing and the deformation during processing is not complex, so TDC51D is usually used. For parts with significant deformation, materials with good formability such as TDC52D and TDC53D should be selected. For components with load-bearing requirements, appropriate structural steel should be selected according to design requirements, such as TS280GD, TS350GD, etc. The commonly used processing methods for color coated boards include cutting, bending, rolling, etc. When ordering, the selection should be based on the characteristics of each processing method. In addition, due to the fact that the mechanical properties of the substrate are usually replaced by those of the color coated board in actual production, and the color coated process may cause changes in the mechanical properties of the substrate, which should be taken into account.
The type of substrate (coating type) and coating weight are mainly selected based on factors such as usage, environmental corrosion, service life, and durability. Corrosion prevention is one of the main functions of color coated panels, and the type and weight of the coating are the main factors affecting the corrosion resistance of color coated panels. Due to the fact that building color coated panels are usually directly exposed to the atmospheric environment, substrates such as hot-dip galvanized sheets and hot-dip aluminum zinc sheets with good corrosion resistance and thick coating are usually chosen. In addition, the corrosion resistance of different types of coatings also varies. For example, under the same coating thickness, the corrosion resistance of hot-dip aluminum zinc coatings is higher than that of hot-dip galvanized coatings. In addition, corrosion resistance usually increases with the weight of the coating, so the corrosion resistance of the color coated plate can be improved by using a substrate with high corrosion resistance and/or increasing the weight of the coating. There are differences in the corrosion resistance of cutting edges of steel plates with different coating types, which should also be noted. In addition, service life and durability are also important factors that cannot be ignored when selecting materials. For example, when long service life and high durability are required, substrates with good corrosion resistance or heavy coating weight should be selected.
