Expanded metal mesh as an architectural design element
Shapes, colours, transparency: expanded metal mesh is a design element for contemporary architecture. Architects and designers use expanded metal design as a building cladding solution to create unique, original facades, and as a decorative application in interior spaces.
The distinctive texture of the mesh — its raised, diamond-shaped openings — turns a technical material into a pure design component.
What makes expanded metal design adapt to different architectural styles?
Expanded metal mesh adapts to different architectural styles because it is available in a wide range of expanded metal mesh types, each offering a different opening shape, mesh density and level of transparency. This range allows architects and designers to select a mesh pattern that fits the specific character of a facade or interior space, rather than adapting the project to a single fixed material.
The mesh also blends the building envelope with its surroundings, adding lightness to the overall structure. This integration between the external environment and the facade is achieved through the various shaping processes the raw material undergoes, which transform a standard sheet into a customised final product suited to the specific project.
What is the difference between expanded metal and perforated metal panels?
Expanded metal mesh is manufactured by simultaneously slitting and stretching a solid metal sheet, rather than punching or cutting material out of it. This process forms diamond-shaped openings directly from the original sheet, so no metal is removed and no scrap is generated during production.
This is the key technical difference between expanded metal and perforated metal panels: expanded metal is stretched from a single continuous sheet, while perforated metal is produced by punching holes into a sheet, a process that generates offcut waste. Because expanded metal remains one continuous piece of material, the mesh also has a raised, three-dimensional expanded metal texture rather than a flat, cut surface.
Folding is carried out using specialized tools, such as presses, that operate with precision according to the thickness and stiffness of each mesh. A folded mesh gives a wavy effect to an expanded metal facade: geometries and rhythm are created across the building’s surface, and the folded mesh also works as a shading solution for sunlight control — reducing energy consumption while keeping interior spaces bright and cool.
The bending process follows the same principle: the most suitable technique is applied based on the stiffness of the specific mesh being processed.
Sensitivity, professional eye and experience transform a simple panel into a designing element.

What colours and finishes are available for expanded metal facades?
Expanded metal facades can be finished in a wide range of colours through painting and anodizing techniques applied by immersion.
Standard colours follow the RAL system, the European colour-matching standard most widely used for architectural powder-coating and cladding specifications; custom Pantone shades can also be matched on request for architects and designers who need a specific tone.
Painting and anodizing are both immersion-based finishing techniques that help the colour and finish endure over time. Beyond aesthetics, these processes strengthen the mesh’s resistance to corrosion and wear from aggressive environmental elements, while retaining every distinctive feature of the expanded metal texture.
