| What you need to know about Wall Sheeting in cyclonic areas... |
| Material Thickness |
|
For wall sheeting in cyclonic area (i.e. Region C), manufacturers recommend
a minimum material thickness of 0.42mm BMT
(i.e. 0.47mm TCT) for wall sheeting.
You may choose the profile for your wall sheeting. The thinner
material thickness costs less per square metre of sheeting, 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 Trimdek and Custom Orb (corrugated) profiles. Both
profiles cost the same per square metre of actual sheeting. Custom Orb performs
slightly better than Trimdek on wall sheeting applications, but it is unlikely to
affect the price. See Custom Orb below.
|
| Trimdek® |
|
Trimdek is a higher ribbed profile with the flat pans. In some rare cases it may mean
an extra girt is required (which would increase the cost).

| Custom Orb® |
|
Custom Orb (corrugated) is often chosen if people want to
have the more traditional Aussie appearance. It's slightly better performance on
wall sheeting applications is a good reason to choose it if you have no particular preference.

|
| 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.
