Please find our Engineering Computation Request form on our website.
Not every single installation is the same.
Different timber, wind categories, and pergola sizes can drastically change
the requirements of our Pergola Brackets.
That’s why Roof Extenda can provide an engineering computation
calculation for your
MkII & S-Series bracket installation.
Y
You can find a request form on our website at
www.roofextenda.com.au
We require that the form is completed in full before we can provide any
calculations for your installation.
This calculation can also ensure you’re using enough brackets, spaced at
an appropriate distance for your project.
Due to the nature of the bracket design, the bracket computation takes into
Due to the nature of the bracket design, the bracket computation takes into
account lateral and dynamic loading.
Please note, we can ONLY provide calculations for the MkII & S-Series
Brackets being installed on existing Timber Frames.
For Shade Sail Anchors:
Be advised that the Shade Sail Anchor has been strength tested.
When bolted in the top holes, the Anchor can deform at 2.3 kN of force.
When bolted in the middle holes, the anchor can deform at 1.3 kN of force.
When bolted in the middle holes, the anchor can deform at 1.3 kN of force.
We advise you carefully evaluate; Shade Sail size, Location, Wind

Roof Extenda works with our manufacturers and
Excellent Plating Works Pty Ltd to ensure all of our products are
Electroplated with Zinc to protect the brackets from the elements and
meet the Australian Standards – AS/NZS/ISO 9001:2000
The Zinc plating is applied by immersing our brackets in a Zinc Salt The Zinc plating is applied by immersing our brackets in a Zinc Salt
Solution, and applying an electrical current through the bath.
This applies a layer of pure Zinctha at 8 - 12 Microns thick, without
hampering the installation of our brackets
While we have tested the durability of the brackets with the Zinc Coating, While we have tested the durability of the brackets with the Zinc Coating,
Roof Extenda cannot provide any guarantees on the lifetime of the
coating, and
recommend checking the brackets annually.
If installing any of the Roof Extenda brackets in highly corrosive areas, If installing any of the Roof Extenda brackets in highly corrosive areas,
we highly recommend that home owners keep the brackets protected
with a Galvanized Paint.
Cold Galvanized Paints can be found at most hardware stores
and can easily be applied to the exposed surfaces of the brackets
for added protection.
