Steel tubing comes in various forms that incorporate round, square, and rectangular shapes. BlueScope Distribution offers a wide range of types with vastly varied dimensions to suit every possible application.

Steel tubing available from BlueScope Distribution is categorised by shape and type:

  • CHC which are circular hollow sections
  • RHS which are rectangular hollow sections
  • SHS which are square hollow sections
  • ERW which are various sections that have been electric resistance welded

CHC – Circular Hollow Sections

CHC sections are commonly used for general engineering, in agricultural settings, and for reticulation.

CHC can be welded, bent, drilled, and screwed. Thickness ranges from 2 mm to 5.4 mm and the nominal diameter or bore ranges from 15 mm to 100 mm. The outside diameter ranges from 21.3 mm to 114.3 mm

The end finishes of CHC sections can be mill cut (or plain), screwed at one or both ends, screwed and socketed, or swaged.

RHS – Rectangular Hollow Sections

RHS has inherently 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 dimensions and thicknesses, as well as combinations of both. Available thicknesses across the board are 1.6 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, 6 mm, 8 mm, 9 mm, 10 mm, 12.5 mm, and 16 mm. Dimensions range from 50 mm x 20 mm to 400 mm to 300 mm.

RHS steel is available in two grades: C350LO and C450LO – both of which are intended for both mechanical and general structural applications.

SHS – Square Hollow Sections

SHS steel tubing has similar uses to RHS and is used for both industrial and construction applications. Square section RHS is available in the same thicknesses as RHS and dimensions range from 20 mm x 20 mm to 400 mm x 400 mm.

SHS is available in two grades: C350LO and C450LO – also intended for both mechanical and general structural applications.

ERW – Electric Resistance Welded Sections

ERW may be square, rectangular, round, or oval. Standard lengths are 6.10 m and 7.32 m which are perfect for many applications including fencing, handrails and balustrades, outdoor furniture, safety ladders, luggage, shopping trolleys, tent poles, and more.
