expamet Expanded Metal mesh

Expamet ‘Expanded Metal’ Mesh as the name implies is a single sheet of mesh produced when a flat base metal plate is simultaneously sheared and stretched into diamond shaped strands and left intact at the knuckles. These are set at uniform angels to add strength and rigidity to the finished product.

Exceptional Strength and Security

The Expamet expanded metal process takes regular steel and expands it into a diamond pattern, making it stronger, lighter, more rigid and more economic than it was before. 

Tough, unyielding and cost-effective, Expamet sets the standard in expanded metal security fencing solutions. Hampden Fence works with two of the leading providers of Expamet expanded metal mesh in Australasia:  Webforge and Locker Group.

The Proven Performance

Expanded metal 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.

Highly Rigid, super Strong

The strands and knuckles are set at a uniform angle to the plane of the sheet. This adds strength and rigidity and distributes the load to the supporting frames. Because there are no welds or joins it operates as a structural member that distributes loads evenly over a wide area.

Anti-Climb Performance with Good Visibility

The high strength to weight ratio makes it suitable for many industrial and high-security applications. No loose strands or welds means minimal deterioration from constant exposure or movement. A further feature is the provision of an excellent anti-climb surface, making it perfect for prison environments.  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.

Excellent anti-slip properties also makes Expamet suitable for ramps (e.g. inclined walkways adjacent to conveyors), platforms and stair treads in commercial sites with an industrial / architectural influence.
