Seamless square and rectangular tube are made of cold-drawn or redrawn production. Seamless square and rectangular tube material and seamless tube material is the same, but also has the same performance and seamless.
Seamless Rectangular Pipe Material:
20 # Rectangular Pipe,
45 #, 10 #, 16Mn seamless square and rectangular tube,
Q345A thick-walled seamless square and rectangular tube,
Q345B, Q345C, ST-37, ST 52, A106, etc. ordinary carbon steel, alloy steel.
In terms of performance, it has many respects superior to solder directly rolled straight seam rectangular Pipe, and it mainly in the plastic yield powerful large, tensile strength, elongation. Due to the characteristics of seamless square and rectangular tube, is widely used in a number of industries, such as construction, machinery manufacturing, steel, shipbuilding, automobile, road and bridge construction, chemical industry, curtain wall etc.
