| What you need to know about Wall Sheeting... |
| Material Thickness |
|
For wall sheeting in non-cyclonic area (i.e. Regions A and B), manufacturers allow
a material thickness of 0.42mm BMT (i.e. 0.47mm TCT) or 0.35mm BMT (i.e. 0.40mmTCT).
You are able to choose both the profile and the material thickness for your wall sheeting. The thinner
material thickness costs less per square metre of cladding, but the allowable girt spacing decreases which
may require additional girts. The cost of the extra girts may increase the overall price. Our wall sheeting
follows manufacturers' recommendations for girt spacing.
|
|
When comparing quotes be sure you check
that the wall sheeting is of the same thickness.
Also, make sure you read our information below on girt spacing.
|
| Your Choices |
 |
We offer Trimclad and Corodek (corrugated) profiles. Both
profiles cost the same per square metre of actual sheeting. Corodek may end
up being more expensive if extra girts are required. See Corodek below.
|
| Trimclad® |
|
Trimclad is a stronger profile. Hence it allows for a
slightly wider girt spacing in the roof frame. In some cases it may mean
fewer girts are required.
|
|
Trimclad is a deeper profile. Hence it
can handle runoff from a higher rainfall intensity.

|
| Corodek® |
|
Corodek (corrugated) is often chosen if people want to
have the more traditional Aussie appearance. It has slightly narrower maximum
girt spacings than Trimclad. In some cases more girts may be required.

|
| Metroclad850® |
|
Metroclad is a lower ribbed profile with a wider coverage than
Corodek and Trimclad. It covers 850mm compared with 762mm. It is slightly less
expensive per square metre, but additional girts are often required which may make
it more expensive in some cases. Metroclad is not suitable for use in cyclonic
areas.

|
|
Metroclad is available in 2 material thicknesses
0.42mm BMT (i.e. 0.47mm TCT) or 0.35mm BMT (i.e. 0.40mmTCT)
In some cases the price saving in choosing the thinner sheeting is lost by
requiring an extra girt.
|
| Girt Spacing |
|
Manufacturers specify minimum wall support spacings (i.e. girt spacings)
for their sheeting materials. The table below shows
the maximum recommended girt spacings in non-cyclonic areas (i.e. Region A and Region B).
|
|
In the next step of your quote, Framing Options, you can view the girt positions
in each of the frame options available to you. These are calculated to always meet the requirements
for the wall sheeting you select.
|
|
Also, the detailed quote you receive by email from us, will show the number
of girts and their respective spacings. This will enable you to do a thorough comparison with
other quotes. When comparing quotes be sure you check
that other quotes meet manufacturers' recommendations for girt (support) spacing
with walling material.
