Fencing should not be located within 1000m of a marine environment or in severe
industrial or corrosive environments. For more information refer to the ‘Selection, Use
and Maintenance of Stratco Steel Products’ Brochure.

engineering advice.
EXAMPLE
Design wind speeds have been determined in accordance with AS1170.2-2002 and
AS4055-1992 allowing for a design return period of 25 years.
This method has been developed by Stratco with the assistance of suitably qualified en-
gineers to comply with the requirements of the above standards.
It is assumed that the soil is natural and in a relatively undisturbed state.
You intend to construct a fence around the boundary of your property. You want to build
a 2100mm high screen top fence with Wavelok cladding. The first step is to work out the
wind speed for your area. By referring to the ‘Determining Wind Speed’ brochure, you
calculate your wind speed is W33.
You determine that the free ends need to be either a three sheet tapered panel or a two
sheet panel that is not tapered by refering to Table 1.3. The internal panels on the rest
of the fence can be standard three sheet panels. The corners need no special treatment.
Using the post spacings in Table 2.0 you can calculate the required number of panels.
Assuming that you intend to use tapered panels on both free ends, all of the post spac-
ings are 2350mm.
From these figures you calculate that the 35 metre sides will require 15 panels, and the
20 metre rear side will need nine panels, making a total of 39 panels.
