... the most important process in the manufacture of cold roll formed profiles and at the same time the most affordable way to manufacture a profile with;
in large quantities (from approx. 5,000 linear meters) and with high precision. It is highly cost-effective since traditional downstream processes can all be integrated into the one roll-forming process, so steps like punching, embossing, clinching and adding thread inserts no longer need an expensive secondary operation.
A wide range of steels, stainless steels and non-ferrous metals can be roll formed.
The input material is a flat strip of steel, stainless steel or a non-ferrous metal of high strength, which is mostly wound in coils of different widths. The process of roll forming (also referred to as cold rolling or roll profiling) involves passing this strip through a sequence of modular pairs of rollers and forming the desired cross-section at room temperature. Each pair of rollers performs a further step in the shaping until the desired profile shape is achieved.
In this way,
Is your extruded aluminum profile no longer strong enough?
A roll formed Welser profile made from high-tensile steel, stainless steel or non-ferrous metal is the answer.
We provide an economic alternative if your aluminum profile does not meet the tight tolerances or requires costly further processing such as tapping or the placing of punch nuts.
Are you still producing your profiles using a press-brake, but need several thousand meters of a certain profile?
We show you that large quantities and constantly tight tolerances are not mutually exclusive, even for extra-long profiles.
We manufacture
Are you wondering whether your idea for a cross-section is achievable?
Configure your own steel profiles and see for yourself how the complex shapes can be achieved through roll forming.
Does your application demand even more complex cross-sections? We make it possible because we have taken roll forming to another level and also produce strip thickness-optimized, variable-height profiles or linear flow split profiles:
