The channel steel body includes a steel waist and steel legs. On both sides of the upper end surface of the steel waist, there are steel legs. Inside the pair of steel legs, near the steel waist, there are installation grooves, and arc-shaped connectors are welded inside the installation grooves. Inside the pair of arc-shaped connectors, there are several first reinforcing ribs and second reinforcing ribs, and the first reinforcing ribs and the second reinforcing ribs are cross-distributed inside the arc-shaped connectors. On the outside of the connection between the steel waist and the steel legs, reinforcing steel is welded. This kind of high-strength channel steel has a simple and reasonable structure, novel design, simple and convenient operation, can effectively improve the strength of the channel steel, and has corrosion resistance and wear resistance effects, and has high practical value.
