The application of power steel rods in the power system at home and abroad is very extensive, however, there are some differences in the production, use, standards and design of power steel rods at home and abroad. This article will be from the following aspects of the difference between domestic and foreign power steel rods.

First, the production process.
The domestic production of power steel rods mainly adopts the welding process, while the advanced continuous casting and rolling process is used abroad. In contrast, the continuous casting and rolling process can guarantee the purity, high strength and uniformity of the steel, thereby improving the service life and safety of the steel rod. At the same time, this process can also reduce defects such as cracks and inclusions in the steel rod, and improve the quality and reliability of the product.
Second, the selection of materials.
There are also differences in the material selection of power steel rods at home and abroad. Domestic power steel rods are mainly made of ordinary steel such as Q235 and Q345, while foreign high-strength steels are used, such as SPA-H, HSLA and so on. High-strength steels have higher yield and tensile strength, which can withstand greater loads and stresses, which improves the bearing capacity and service life of steel rods.
3. Structural design.
There are also certain differences in the structural design of power steel rods at home and abroad. The structural design of domestic power steel rods is mainly carried out according to national standards such as GB50233-2005, while foreign international standards such as ISO and EN are adopted. In addition, foreign power steel rods pay more attention to details and optimization in structural design, such as optimizing the cross-section, reducing the diameter of the shaft, etc., in order to reduce the weight of the steel rod and improve the transportation efficiency.
Fourth, anti-corrosion treatment.
There are also differences in the anti-corrosion treatment of power steel rods at home and abroad. Domestic power steel rods are usually treated with hot-dip galvanizing anti-corrosion, while foreign ones are treated with hot-spray zinc + paint anti-corrosion. Thermal spray zinc anti-corrosion treatment has long durability and good adhesion, which can improve the corrosion resistance and service life of steel rods. The paint anti-corrosion treatment can further improve the anti-corrosion performance and service life of the steel rod, and at the same time, different types of paint can be selected for coating according to different use environments and requirements.
Fifth, the use of the environment.
There are also differences in the use environment of power steel poles at home and abroad. The use environment of domestic power steel rods is usually complex, including the influence of climate, geology, environment and other factors, while foreign countries are usually used in a relatively single environment. Therefore, it is necessary to consider the impact of the use environment when selecting the power steel rod, and choose the appropriate power steel rod according to the specific use environment.
To sum up, there are certain differences between domestic power steel rods and foreign power steel rods in terms of production process, material selection, structural design, anti-corrosion treatment and use environment. In practical applications, it is necessary to select the appropriate power steel rod according to the specific use environment and requirements to ensure its safety and reliability.
