Expanded Metal

Expanded metal — known in French-speaking and many European technical contexts as déployé — is a versatile sheet material produced by simultaneously slitting and stretching a solid metal sheet (most commonly steel, stainless steel, or aluminum) in a single cold-forming operation, without any material being removed or wasted. The result is a rigid, integrally connected mesh of diamond-shaped apertures bounded by angled strands and bonds, available in a wide range of opening sizes, strand thicknesses, and sheet dimensions.

It is widely used in architecture, construction, industrial manufacturing, and infrastructure — appearing as façade cladding, sunscreens, security fencing, walkway gratings, machine guards, reinforcement for plaster and renders, and filtration or ventilation grilles.

It offers a unique blend of geometric precision and organic fluidity. The interplay of light and shadow on its surfaces enhances its visual appeal, making it a favorite among architects seeking innovative solutions.

Key Benefits

  • Aesthetic appeal
    Expanded metal mesh creates a striking visual effect, adding texture and depth to a building’s exterior
  • Natural ventilation
    The open pattern allows air to flow through the facade, which helps improve ventilation inside the building.
  • Sun shading and energy efficiency
    Expanded metal mesh acts as a sunshade, reducing direct sunlight and helping to lower interior temperatures.
  • Durability and low maintenance
    Expanded metal facades are highly durable and resistant to weather conditions.
  • Sustainability
    Expanded metal mesh is often made from recyclable materials and uses minimal metal due to its manufacturing process.
