Expanded mesh is one continuous single sheet of mesh produced when a flat metal plate is sheared and stretched but is left intact at the ‘knuckles’. It is available in a variety of thicknesses with differing sizes and designs of the apertures. A further feature is the provision of an excellent anti-slip surface. This makes the product suitable for ramps (e.g. inclined walkways adjacent to conveyors) platforms and stair treads. The open nature of the product provides good visibility through the mesh as well as the easy passage of air and sound whilst ensuring security and protection.
