What Is Expanded Metal?

Expanded metal is plate or sheet that has been cut and stretched into a mesh. Stretching the metal results in a mesh with diamond-shaped spaces – although many other patterns can be created. Many types of metal can be expanded, including: stainless steel, hot rolled steel, cold rolled steel, aluminum and more.

The pattern of the mesh can either be staggered (providing the most open area) or in a straight pattern with all rows and columns aligned. The proportion of open area determines the amount of space for the passage of air, water and light, and will vary according to the intended application of the expanded metal.

How Is Expanded Metal Made?

Expanded metal is produced by an expanding machine, which turns solid metal sheets and coils into an expanded metal mesh. The expanding machine is fitted with a knife which determines pattern for the mesh. As the metal is fed through the expanding machine, it is cut and stretched simultaneously using a pressured slitting and stretching process. The slits created by the knife allow the metal to be stretched, which produces uniform holes. To ensure a consistent pattern, the expanding machine is programmed or operated manually as the metal is fed through. The finished expanded metal is then wound into coils or cut into sheets.

Depending on the intended application, different thicknesses of metal can be used and different mesh patterns can be chosen. L.W.D (Long Way Diamond) and S.W.D. (Short Way Diamond) are commonly used to indicate the desired length and width of the diamond shaped mesh holes.

Why choose expanded metal?

There are several benefits to using expanded metal:

1.Cost-effective: A small quantity of metal can be stretched into a large piece.

2.Efficient Process: There is very little waste when manufacturing and processing expanded metal mesh.

3.Good conductor: Because expanded metal is one piece, it can be excellent conductor of electricity, magnetic flux, and heat.

4.Protective reinforcement: Expanded metal meshes can be combined with glass, concrete, and other materials for added strength.

5.High strength: Expanded metals support weight and withstands stress better than woven metals or jointed welds.

6.Low weight: Expanded metals are lighter than traditional metal sheets.

7.Allows circulation: Expanded metal allows air and light to move freely.

8.Acoustic properties: Specially developed meshes can enhance acoustics and provide soundproofing.

Standard Expanded Metal

Standard expanded metal is extremely versatile and economical. It comes in a variety of gauge and opening sizes.

 It's often used to provide a rigid, raised, slip-resistant surface. In standard expanded metal the strands and bonds are set at a uniform angle. This provides extra strength and rigidity whilst allowing maximum air circulation.

Flattened expanded metal

Flattened expanded metal is produced by cold rolling expanded metal to flatten it. It is chosen when a smooth surface is required. The flattening process generally elongates the length of the sheet by 5%.

Hexagonal expanded metal

Hexagonal expanded metal has hexagonal openings instead of the usual diamond ones. The hexagonal shape gives the metal extra strength while allowing the passage of air, light, heat, sound and liquid. Hexagonal openings are preferred over diamond openings when the metal is heavily expanded.

Architectural expanded metal

Architectural expanded metal features the diamond pattern with added architectural features. The result is a design which combines good aesthetics, increased security and privacy, and improved ventilation. It's suitable for functional and decorative purposes, or a combination of the two.

Micro expanded metal

Micro expanded metal features small openings in light gauge metal. The openings can be standard, flattened, hexagonal and square. This type of expanded metal is often used in filters.

Expanded Metal Ceilings

Expanded metal ceilings have become an indispensable part of modern architecture. Unlike other ceiling systems, they do not appear to be one smooth surface but give you a more or less unobstructed view of the ceiling void, depending on your specifications.

 Elaborate illumination or backlighting creates a spectacular play of lights and shadows that distinguishes expanded metal ceilings from all others. 

Expanded Metal Fencing

The expanded heavy plate mesh is used for heavy mechanical pedal mesh, boiler, mines, locomotives and tonner steamship working platform, escalator, aisle
