The patented UltraSTEEL® process is a method of imparting a unique dimpled texture onto the surface of cold formed products. This is achieved prior to the main forming operation by passing the unformed flat strip through a set of mating UltraSTEEL® rolls. See photograph below.

The material is then passed through standard roll-forming equipment until the finished product is formed.

* The process does not reduce the formability of the material and any thin gauge profile can be manufactured using UltraSTEEL® that could be roll-formed in plain material.
* No extra equipment or expenditure is required, and the process is employed within a standard rollforming line.

UltraSTEEL® differs from other more traditional processes associated with cold forming in the way that the material is made to flow by the shape of the UltraSTEEL® rolls. The pattern of the UltraSTEEL® strip is formed by working the material from both sides at once, producing the revolutionary “Double Helix” pattern. In so doing the material undergoes a great deal of localized stretching, unique to the UltraSTEEL® process. The double helix shape also ensures that the pattern is uniform throughout the whole strip, with no overall thinning or weak points. Through every plane across through the cross section of the strip there is a consistent ‘wave’ pattern formed. Locally, this wave pattern has the effect of locally stiffening the strip in every direction, and improving the mechanical properties of the material.
