International Specifications Compared
Tubecon cold forms our structural welded steel hollow sections according to the SANS (South African
National Standards) specification. We manufacture all our steel sections and open profiles according
to the SANS specifications. This includes our electrical steel conduit, conveyor tubes, galvanized
tubing, side impact bars, water pipe and general circular, rectangle and square steel tubes. The
standards for the variety of SANS specifications that we manufacture to can be viewed the at the top
of the Specification page under Technical Info on this website, or click on the following link:

The table below indicates the various international standards for welded cold-formed structural
tubing; round, square and rectangular. These specifications can be compared to the steel types that
Tubecon currently use in our roll forming of structural tubes and profiles. The material grades can be
