ABOUT SIENA EXTREME
Built on the proven Siena platform, the Extreme model upgrades the folding arm to a heavy-duty 4m arm assembly, giving you the deepest shade footprint we offer in a folding arm awning. Maximum size reaches 15m × 4m, making it ideal for wide-span entertaining areas, hospitality venues and architectural commercial facades.
Sleek European design, environmentally friendly operation and superior arm strength sit at the core of every Siena Extreme. Premium acrylic fabrics provide outstanding UV protection while keeping outdoor rooms cool, comfortable and usable all year round.
THE SIENA EXTREME SPECIFICATION
Engineered for Australia’s Climate
The Siena Extreme is the deep-projection member of the hardback Siena folding arm awning family. With 4m arms and a maximum size of 15m × 4m, it’s purpose-built for the largest residential alfresco areas and commercial outdoor spaces.
Premium European engineering, full 90° pitch and the option of either Colorbond or extruded aluminium pelmet make the Siena Extreme one of the most capable retractable awning systems available in Australia.

4M ARMS
The deepest projection in the range
The Siena Extreme upgrades the standard Siena to heavy-duty 4m folding arms, unlocking projections that no other awning in the hardback range can match.
Spanning up to 15m wide as a single coordinated installation (with multiple units), the Extreme is engineered for serious shade across alfresco entertaining areas, restaurants, pool surrounds and outdoor function spaces.
Widths over 6m are recommended to be motorised for smooth, reliable operation and to protect the arm assemblies from over-torquing.
BUILT STRONG
8-link chain and full 90° pitch
Every Siena Extreme uses the same 8-link stainless steel arm chain that makes the standard Siena one of the strongest folding arm awnings available — scaled up to suit the 4m arm assembly.
The aluminium front rail acts as a rain gutter, channelling water to the edges of the covered area, while the installer-adjustable pitch lets you dial in shade angle anywhere from 0° to 90°.
Choose Face Fit, Fascia, Eave or Roof Mount and finish in White, Ivory, Silver or Onyx — or specify a custom powder coat to suit your project.
