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
