All cold formed sections are manufactured to customers' specifications from prime quality hot rolled steel that complies with the requirements of SANS 10162:


Cold-formed sections made of commercial quality steel, which does not have a guaranteed minimum yield stress. On part one of the above standard the minimum yield stress is 200 mPa and tensile strength of 365 mPa can be used for commercial quality steel. Cold-formed sections with a specified yield strength can be supplied on request according to SANS 1062:


Cold formed open sections conform to the following thickness tolerances:

2.0 mm ± 0.18 mm

2.5 mm ± 0.18 mm

3.0 mm ± 0.20 mm

Below is a list of industries and the types of cold formed steel tubes and profiles that are used:

Properties of cold formed steel sections include:

Open sections are cold formed steel profiles that has a perceptible gap between two of the profiles edges. The fact that the opening is wide from one edge to another distinguishes open profiles from closed profiles and welded sections.

Open sections include cold formed products such as:

Heavier profiles include profiles such as fencing posts, top rails and side rails.

Open profiles are a very effective for a customer to save on cost and weight while keeping the strength of the profile intact. Cross-member sections used in trailer manufacturing are one such example on saving on weight. A custom-cold formed profile has the added advantage that very tight tolerances can be achieved while forming large quantities.
