First: The Principle Of Selection
1. Strength requirements: steel plates for steel structures need to meet certain strength requirements, so it is necessary to choose the appropriate strength grade according to the specific engineering needs to meet the requirements of the project when purchasing.
2. Corrosion resistance: Steel plates for steel structures are usually used outdoors or in high humidity environments, and they need to have certain corrosion resistance to ensure their service life. When selecting a steel plate, it is necessary to consider the environmental conditions and choose a steel plate that can meet the requirements for corrosion resistance.
3. Processing performance: When processing steel plates, it is necessary to consider their processing properties, that is, whether they are easy to cut and can maintain dimensional accuracy. If the processing performance of the steel plate is poor, it will affect the quality and progress of the project.
4. Cost factor: The cost factor of steel plate also needs to be taken into account, especially in large-scale projects, the cost factor may become one of the important factors in determining the selection of materials.
Second: Commonly Used Types
1. Ordinary carbon structural steel plate: This kind of steel plate has high strength and good processing performance, and is often used in some general building structures.
2. Low-alloy high-strength structural steel plate: Compared with ordinary carbon structural steel plate, this type of steel plate has higher strength and is usually suitable for large-scale buildings.
3. Weather-resistant structural steel plate: This type of steel plate has weather resistance and good strength, can be used outdoors and in high humidity environment for a long time, and is often used in bridges, high-rise buildings and other structures.
4. Wear-resistant structural steel plate: This kind of steel plate has wear resistance and good processing performance, and is often used in mechanical structures with high wear resistance requirements, such as the bucket of the excavator and the hammer of the crusher.
