    Expanded Metal Mesh

  • An Introduction to Expanded Metal

    Catalogue GuideWhether you are familiar with our products or whether it is all new to you, this catalogue is designed so that you can find the mesh that you need quickly and easily. You will see by the contents page that our meshes are organised firstly by material type. Then on each page the meshes are arranged from small to large. Meshes are then separated into raised then flattened.

    The scans on the opposite page correspond to the tables so that you can choose a pattern specification and size to suit your needs and see the stock availability and standard sizes.

    You can view the fold out Technical Guide at all times when using the catalogue, if necessary. This will clarify the technical references used in the expanded metal industry as well as showing you what you need to consider when ordering mesh. The diagrams in the Technical Guide show how our meshes are measured, by individual diamonds and in sheets.

    The column entitled Stock Size indicates the products that we hold in stock and gives the size available. These are usually available for next day delivery. The column entitled Standard Manufactured Sizes indicates the sizes in which that particular mesh is usually made. Lead times for standard manufactured products can be obtained from the sales desk. We also have the ability to produce mesh to specific sizes to meet your requirements.

    Expanded metal is a unique material with a fascinating production process, that can turn any ductile solid metal into thou-sands of varieties of mesh. The process of stretching and slitting gives the well known, traditional diamond shaped pattern, as well as a large range of decorative shaped meshes. This can vary in diamond size, from minute gauze to massive walkway. Meshes can be as thin as foil or as weighty as heavy duty walkway.

    What is Expanded Metal?The process for expanding metal was first patented in Hartlepool, UK in the 1880s and despite the amount of time which has elapsed since then, the process remains true to the original idea. Most types of metal, including precious and specially produced metals, can be expanded. Other materials, such as some plastics or any other ductile material can also be expanded. The proc-ess is simple but incredibly effective...

    Sheets or coils of metal are fed into the expanding machine. A little metal can create a lot of mesh.

    Each machine is fitted with a

    unique knife, dedicated to a

    particular pattern.

    The machines are then programmed or manually controlled to ensure the metal is expanded to exact specification.

    Using the unique shearing and stretching process means very little waste is created. The metal is sheared and then stretched in a single process creating the

    apertures and therefore expanding the metal. The mesh is then either cut into sheets or wound onto coils ready for shipping or further processing.

  • Who we are...


    The Expanded Metal Company Limited is the original pioneer of expanded metal mesh, so you can be assured of expert advice, high quality products and what we believe to be the most comprehensive range of meshes available. As market leaders, we have set the highest standards for lead times, customer service levels and quality.

    Each mesh pattern you see can be produced in other ductile materials to your specifications, not only in the material stated. It is not possible to state each mesh pattern in each material because of the infinite number of possibilities this presents. If you need further assistance or information, please contact our sales desk or visit our website.

    World Class Manufacturing Company

    Over the following pages we hope that you will gain a greater understanding of The Expanded Metal Company, our products and capabilities. You will discover that expanded metal mesh has a diverse range of benefits and is available in numerous material types and patterns. We serve markets worldwide as well as local companies with a range of mesh products and components.

    If you require further information, technical guidance or product samples, please contact us, we will be happy to assist you. Our business is driven by our dedication to fulfil and surpass customer requirements and mar-ket demands. We enjoy working alongside our cus-tomers as partners to develop mutually beneficial relationships and new products, to secure continual growth for the future.

  • Expanded Metal Features and Benefits

    Expanded metal mesh has a diverse range of properties, which makes it so versatile and appealing for many uses and applications throughout industry. Here are some of the key strengths of expanded metal mesh:

    Feature Benefit

    The mesh is formed from a single piece of metal

    The process is not wasteful of material

    Higher strength-to-weight ratio than sheet metal

    Anti-slip surface

    Excludes and retains simultaneously

    Premium reinforcement properties

    Practical and effective screening

    Highly efficient conductor

    Super corrosionresistance

    Which means that there is 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.

    The expanding process involves slitting and stretching the metal to create holes rather than punching them out. This provides cost savings, especially 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. Expanding metals is a traditional method, which complies with modern green engineering standards. (see page 23)

    Test results are available from extensive research carried out with The University of Teesside to validate the strength to weight ratios of Expanded metal meshes. Hard to believe but tested and true. By expanding metal from its solid sheet form additional strength is added. This makes mesh ideal for catwalks, ramps, walkways and platforms. The uncut knuckles of expanded mesh withstand stress better than welds or joints.

    The knuckles formed by expanding mesh give sound grip underfoot, particularly beneficial when used in stairtreads, ramps and walkways. We have also developed a range of specific anti-slip walkway meshes.

    Mesh acts as a barrier for security and storage. For example, our meshes are excellent for grain storage as they allow the circulation of air but keep vermin out. Our Securilath range prevents illegal access through walls and partitions whilst strengthening the area it covers. For more information on our Securilath range request a brochure.

    Expanded metal mesh can be combined with other materials to give products added strength. For example, glass, plastics and other composites can be either incorporated into, or attached to, meshes for increased strength and security purposes or aesthetics.

    Taking a sample of mesh and looking through it at various angles best illustrates the visual properties of expanded metal meshes. Wide strand meshes are used in architectural solar screens on the exterior of buildings and throughout interiors for decorative grilles.

    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.

    When suitably coated, expanded metal mesh performs better than woven and welded mesh due to jointless continuity of mesh. Our mesh is ideal for use with industrial acids as in electroplating baskets and in seawater for fish cages and lobster pots.


  • Mild Steel


    Steel MeshesAll of our Steel Meshes are made from a variety of grades. The most common grades are Hot Rolled, Cold Reduced, Electro Zinc and Galvanised Steel. All materials can be coated using various applications, i.e. galvanising, painting, powder coating, etc. All Steel grades supplied conform to the relative quality standards. Other materials and non-standard meshes can also be produced to order.
