Profiling is a continuous cold-forming process based on sheet or coil metal. It produces parts called profiles, generally much longer than they are wide, with essentially constant cross-sections.
The metal strip is drawn between successive pairs of rollers, which gradually shape it into its final form. Essentially, roll forming is a continuous bending operation. In particular, thickness variations are minimal, at least outside the bends.
Profiling products can be found in applications linked to public works (sheet piling, freeway guardrails), construction (structural elements, roofing, flooring, cladding, ceilings, doors, scaffolding), interior fittings (furniture, household appliances), storage (shelving), transport (longitudinal members, door frames) and agriculture (vineyard stakes, fencing systems, silos).
