Special profiles from Welser

(Almost) everything is possible thanks to roll forming and our Creator, an online tool that helps you to draw the profile you want.

To the Welser Creator

Roll forming

... the most important process in the manufacture of steel profiles and at the same time the most affordable way to manufacture a profile with

  • strip thicknesses from 0.3 to 8.2 mm
  • strip widths up to 1,000 mm
  • profile lengths up to 27,000 mm
  • profile heights up to 320 mm

in large quantities (from approx. 5,000 linear meters) and with high precision. That is mainly because machining steps like perforating, slitting, embossing or the incorporation of threads can be integrated into the roll forming process. The result is an excellent depth of production at an affordable price.

Roll forming

What happens during roll forming?

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.

The advantages

  • Material properties remain practically unchanged, and in some instances are even improved.
  • Better functionality: roll forming enables more complex cross-sections to be created than conventional sheet metal machining.
  • Variety of cross-sections: our in-house tool shop and the extensive range of machines bring flexibility in terms of change, response times, etc.
  • Positive life-cycle-assessment: Forming at room temperature, a high material utilization and excellent recyclability makes roll forming a particularly energy-efficient process.

In this way,

  • we increase your quantities and margins 
  • we simplify the automated further processing and your production process.
New Call-to-Action

High-tensile steel instead of extruded aluminum

Is your extruded aluminum profile no longer strong enough?

A roll-formed Welser profile made from high-tensile 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.


Roll forming instead of Press-braking

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.


What are roll-formed profiles?

We manufacture

  • special profiles, profile tubes or entire assemblies
  • perforated or unperforated
  • straight or curved
  • with the tightest tolerances and enhanced functionalities


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:
