Product Description and Features
SANKEY GRIDMESH® is a light yet strong expanded metal mesh used extensively in walkways, ramps and flooring.

SANKEY GRIDMESH® comes in two series. The GR series is a comparatively open product suitable for general purpose applications, while the GM series has smaller openings and is recommended for heavy duty applications.

• Available in both uncoated and galvanised steel
• Non-skid surfaces
• Suitable for rural applications
• Complies with AS 1657-1992

Common Uses of this product
Walkways, ramps, flooring, stairways, fixed platforms.

Notes:

1. The above table is based on the XPM Industry Standard 1001 - Testing of Load Bearing Expanded Metal (Structural Meshes).
2. Load capacities given in the table are for LYSAGHT GRIDMESH® spanning in LWM Direction over clear spans,having every fourth strand welded to support with a minimum landing of 25mm.
3. The uniform and concentrated load capacities are essentially the same for double and triple spans. Linear interpolation and extrapolation are permitted.
4. Uniform load capacity is the maximum load just prior to permanent deflection (set) of mesh. Permanent set being span/500 or 0.80mm, whichever is greater.
5. "Deflections" shown in the table refer to uniform loads causing a deflection of 10mm or span/360, whichever is less.
6. Concentrated loads have been applied through a 100mm diameter plate. They correspond to a localised deflection of 10mm.
7. For large simple spans the load carrying capacity is generally governed by deflection; for double and triple spans by uniform or concentrated loads.
8. A load of 102kg approximates 1kN.
9. A load of 102kg/m2 approximates 1kPa pressure.

Installation Information
The following accessories are available to ensure easy fixing and proper finishing of your expanded metal project.

Clamping Methods
A galvanised steel fastening clamp set is available for "GM" and "GR" series SANKEY GRIDMESH® expanded metal. The clamp set consists of top and bottom plate and bolt.

Note: All steel surfaces in contact with aluminium gridmesh should be painted with zinc chromate.

Method for "GM" and "GR" series.
