RHS has inherenty flat surfaces that make it more economical when it comes to joining and fabrication. Also, RHS is functional with clean lines and is used for construction and architectural applications.
RHS is manufactured in a wide range of diensions and thicknesses, as well as combinations of both. Available thicknesses across the board are 1.6mm-20mm.Dimensions range from 50mmx20mm to 400x30mm.
Xunhong steel co.,Ltd is manufacturers & suppliers of rectancular tube, passed 1S09001,SGS and other certificates, accept third-Party testing.Feel free to contact us anytime.
A500 Gr-B:Standard specification published by the ASTM for Cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.
A513:0ffers high weldability and is used frequently in structural applications in bridges and buildings as well as in both the automotive and appliance industry
