Steel profile

metalstainless steelspecial

Overview
Cold roll forming is the primary process for manufacturing high‑precision metal profiles in large volumes. A flat strip of steel, stainless steel or high‑strength non‑ferrous metal is formed at room temperature by passing it through a sequence of modular roller pairs. The process can integrate downstream operations (punching, embossing, clinching, inserting threaded elements) into a single continuous flow, improving cost efficiency for series production.

Capabilities

• Strip thickness: 0.3–8.2 mm
• Strip width: up to 1,000 mm
• Profile length: up to 27,000 mm
• Profile height: up to 320 mm
• Economical for high volumes (from approx. 5,000 linear meters)

What is roll forming?
The input material is a flat coil of steel, stainless steel or a high‑strength non‑ferrous metal. The strip is guided through successive pairs of rollers; each pair performs one shaping step until the target cross‑section is reached. This cold forming process is also known as cold rolling or roll profiling.

The advantages of roll formed profiles

• Material properties remain practically unchanged and can be improved in some cases.
• Better functionality — enables more complex cross‑sections than conventional sheet metal processes.
• Variety of cross‑sections — in‑house toolmaking and a broad machine park provide flexibility for changeovers and short response times.
• Positive life‑cycle assessment — forming at room temperature, high material utilization and excellent recyclability increase energy efficiency.

What we manufacture

• Custom profiles, profile tubes or complete assemblies
• Perforated or unperforated profiles
• Straight or curved profiles
• Profiles with tight tolerances and enhanced functionalities

Advanced possibilities
We produce strip‑thickness‑optimized profiles, variable‑height profiles and linear‑flow split profiles to meet demanding applications and complex cross‑section requirements.

Materials
A wide range of steels, stainless steels and non‑ferrous metals can be roll formed. Roll forming is an economical alternative to extruded aluminum where higher strength, tighter tolerances or integrated processing (e.g. tapping, punch nuts) are required.
