Structural Tubes, also known as hollow sections, are used as a structural element in buildings, bridges and other structures, and in a wide variety of manufactured products. It’s produced in round, square and rectangular shapes in a broad range of sizes and gauges.
Square Tube, similar to round tube, has efficient shape for multiple-axis loading as it has uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes it good choice for columns. It also has excellent resistance to torsion.
Square steel tube can be used in many places such as urban construction pipe, machine structure pipe and agriculture equipment pipe. Welcome to choose us!
We also provide Galvanized Steel Pipe, Square Steel Pipe, Carbon Steel Pipe Cap, bend Pipe
