Features & Benefits of Expanded Metal
Expanded metal mesh has a diverse range of properties, which makes it so versatile and appealing for many uses and applications throughout a variety of industries. From our aluminium foils measuring just 50 microns thick, through to our heavy duty 6mm thick walkway range, we offer a class leading range of choice.
Formed from One Piece of Material
Nothing to work loose, no fretting strands or strained joins or welds. This makes expanded mesh ideal for forming and beneficial to further processing such as pressing and shearing. The strength of mesh makes it valuable for use in multiple components.
Minimum Waste
Our process involves slitting and stretching material to create holes rather than punching it out. This provides immediate cost savings, especially when compared to other metal processing methods. For example, when perforating metals, all of the holes you see are wasted and must be paid for by you.
Strength to Weight Ratio
By expanding metal from its solid sheet form additional strength is added. The uncut knuckles of expanded mesh withstand stress better than welds or joints. This makes expanded metal an ideal light weighting solution whilst also maintaining strength.
Aesthetics
Taking a sample of our mesh and looking through at various angles best illustrates the visual properties of expanded metal meshes. Favoured by designers and architects for an array of cladding, screening and interior features, our product is available in a wide array of colours, materials and designs.
Highly Efficient
Electricity, magnetic flux and heat can all flow through expanded metal mesh, as there is a continuous connection throughout each sheet. There are no breaks or welds because the mesh has been formed from a single piece of metal.
Anti-slip
The knuckles formed by expanding mesh give sound grip underfoot, particularly beneficial when used in stair treads, ramps and walkways. We have also developed a range of specific anti-slip walkway meshes.
