Contact Clotan Steel for price options on lipped channel products.

Clotan Steel invested in state-of-the-art slitting and rollforming facilities in order to manufacture a full range of cold formed lipped channel and lipped angle. By investing in modern equipment Clotan Steel is able to provide the following benefits to the construction industry:

• Quick setup facilities on our equipment facilitate short lead times and a flexible service;

• Orders can be precision cut to length at high speed in order to eliminate length variances;

• Cutting the material to length before the profile is formed eliminates unwanted burs on the ends of the sections;

• An unique “camber corrector” guarantees tight dimensional tolerances, thus eliminating twist, camber and straightness problems.

• Can be supplied in various finished like Z275 Pre-Galvanized, Hot Dip Galvanized, Magnesium Zinc or plain black steel.

• In-line punching can be done to customers specifications, subject to certain dimensional limitations

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

SANS 10162: (Part One) regulates:

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:

SANS 10162: (Part Two) governs that:

Cold formed sections conform to the following thickness tolerances:
