Steel Specification

25.4mm x 1.2mm Wall Diameter - Z35 High Tensile Galvanised
35.0mm x 1.5mm Wall Diameter - Z35 High Tensile Galvanised

The Tube End finishes available are as follows:

F: Flattened - The end of the tube will be a rounded shape and the tube squashed flat together. There is also a drilled hole.

S: Swaged - The diameter of the tubing is reduced at the end to enable it to slot together with another piece of plain tube.

P: Plain - Normal tube end.

The length of swage for each tube are as follows:

  • 25.4mm-51mm
  • 35.0mm-70mm

A 'Flattened' joint creates a nominal loss in length of 5mm - Example a tube 100cm long (1000mm) with 'Flattened Ends' at each end will result in a final length of 99cm (990mm).

A 'Swaged' joint creates an OD that will fit our supplied tube 'Plain' and adds a nominal increase in length of 2.5mm - Example a tube 100cm long (1000mm) with 'Swage Ends' at each end will result in a final length of 100½cm (1005mm).
