Flormesh

Flormesh expanded metal is a tough and durable product with a high strength to weight ratio.

Flormesh is available in four profiles and two finishes, untreated or hot dipped galvanised to AS/NZS.4680.1999.

Flormesh expanded metal is a tough and durable product with a high strength to weight ratio that only steel can provide, making Flormesh the ideal product for many applications.

Flormesh can be used for walkways, stairtreads, work platforms, ramps, flooring and security screens.

Flormesh ensures complete safety under most conditions due to non slip surface, especially useful where cleated surface would normally be required.

NOTES
  1. The above tables are based on the XPM Expanded Metal Industry Standard 1001.
  2. Load capacities given in the table are for Flormesh spanning the LWM direction over clear span and having every fourth strand welded to the support with a minimum landing of 25mm.
  3. Uniform distributed load is the maximum load just prior to permanent defection (yield) of mesh. Permanent yield being span/500 or 0.80mm, whichever is greater.
  4. "Deflections" shown in the tables refer to uniform distributed loads causing a deflection of 10mm or span/360 whichever is less.
  5. Concentrated loads have been applied through a 100mm - diameter plate.  They correspond to a localised deflection of 10mm.
  6. Flormesh expanded metal walkway mesh behaves like a net, when heavily overloaded can carry loads far in excess of recommended data shown.  The inherit properties of expanded metal walkway mesh provide maximum safety pursuant to complete failure.
  7. For large simple spans the laod carrying capacity is generally governed by deflection; for double and triple spans by uniform or concentrated loads.
  8. A load of 102kgs approximates to 1kN. A load of 102kgs/m approximates to 1kPa.

Fastening Methods
The most positive fixing method and by far the most economical is on-site welding of the mesh to support steelwork.  Where panels are to be removable or where surface treatment of the mesh may be damaged, Flormesh fixing clips are recommended.  These can be installed and made secure by personnel working from the top of the mesh.  Flormesh fixing clips come in a standard galvanised finish.  It is recommended that a minimum of 8 clips should be used per 3m sheet.

Another alternative for fixing is with self-drilling or thread cutting screws and a top clamp.  This may be used in locations where there is no open flange on the supporting steelwork to clamp to.
