General Information
Expanded Metal Terms
LWM – Long Way Measurement. Dimension taken from the centre of one
knuckle to the centre of the adjoining knuckle, measured along the “long way”
of the diamond/profile (see diagrams).
SWM – Short Way Measurement. Dimension taken from the centre of one
knuckle to the centre of the adjoining knuckle, measured along the “short way”
of the diamond/profile (see diagrams).
Strands & Knuckles – Expanded metal is made up of strands & knuckles.
Strands form the sides of the expanded metal opening and the knuckle is the
intersection of two strands.
Thickness – The thickness of the parent sheet metal, which remains unchanged
during the expanding process.
Sheet Direction – LWM x SWM (see diagrams below).
Tolerances
All measurements specified are
nominal and approximates only.
Although every effort is made to
ensure these dimensions are accurate,
they are subject to standard industrial
manufacturing tolerances.
Finishes
Hot-Dip Galvanised: NEPEAN
Building & Infrastructure has its
own in-house galvanising plant,
providing a 24-hour service. The hot-
dip galvanising process produces a
durable, abrasion-resistant coating of
metallic zinc and zinc-iron alloy layers
metallurgically bonded to the steel
base. This finish is not recommended
for fine meshes, as they are prone to
distortion and windowing effects.
Hot-dip galvanising conforms to AS/
NZS4680:1999.

Fabricating Expanded Metal
Conventional sheet metal working
techniques are used for fabricating
expanded metal, including cutting,
bending and welding.
Non-standard Products
We have provided many special-
purpose expanded metals to suit
unique applications. If you have a
requirement that is not covered in
this catalogue, please contact your
nearest sales office (details on back
cover) for further information.

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 a
clear span with every fourth strand welded to
the support and a minimum landing of 25mm
(preferred industry standard).
3. Uniform distributed load is the maximum
load just prior to permanent deflection (yield) of
mesh. Permanent yield is span/500 or 0.80mm,
whichever is greater.
4. Deflections in the tables refer to uniform
distributed loads causing a deflection of 10mm or
span/360, whichever is less.
5. Concentrated loads were applied through a
100mm diameter plate. They correspond to a
localised deflection of 10mm.
6. For large simple spans the load carrying capacity
is generally governed by deflection; for double and
triple spans by uniform or concentrated loads.
7. A load of 102kg approximates to 1kN. A load of
102 kg/m2 approximates to 1 kPa.
