Expanded metal is a product that is manufactured by systematically forming a metal sheet or coil. The raw material is cut horizontally with a knife and stretched in length. This process creates uniform holes that form a three-dimensional structure. Expanded metal is characterised by its high stability combined with flexibility and low weight and is often used in architecture, mechanical engineering and the automotive sector. Expanded metal can also be used for filters, shopfitting, batteries, renewable energies, fences, railings, facades, ceiling and wall cladding.
Depending on the material and mesh, our products can be flat rolled up to a thickness of 3.0 mm. The surface is then smooth – similar to a perforated sheet.
Due to its production method, expanded metal guarantees a homogeneous structure without additional welds.
Yes – any shaping and processing is possible. However, the choice of material and the mesh dimensions have a decisive influence on the behaviour of the material. We will be happy to advise you on your specific application.
Welding, riveting, screwing or framing with frame profiles are common methods of attaching expanded metal.
Yes. Expanded metal can be coated like any other metal product in the usual processes. We recommend that you seek advice on the optimum coating process for your project.
As the expanded metal is three-dimensional due to the way it is manufactured, the different views must be taken into account when installing elements, especially in the visible and design areas. Depending on the orientation of the grilles, for example, the air or light permeability changes. We will be happy to advise you further.
All tolerances such as mesh parameters, flatness, overall thickness, free cross-section or even mesh widths and lengths are agreed individually with our customers. In addition, all our expanded metals are subject to the expanded metal standard 791.
