12 x 12 FT Octagonal Sunroom Trellis

This dark grey aluminium trellis forms a 12 by 12 foot octagonal sunroom for the garden. The galvanised steel sloping roof sheds water and snow efficiently. It creates a sheltered space suitable for a studio, lounge or extra room outdoors.

Moveable PE screens and lockable sliding door

The PE screen walls slide to adjust privacy, wind protection and rain resistance as needed. A lockable sliding door secures the entrance while allowing quick access. Together they let the owner reconfigure the enclosure for different uses.

Aluminium frame with galvanised steel roof

The structure uses thickened aluminium with a dark grey powder coating for corrosion resistance. The roof panels are galvanised steel sheets built for long-term outdoor exposure. This material combination determines durability in varying weather.

Questions about this item

How often will the powder-coated aluminium frame need re-coating or touch-up paint?

The dark grey powder coating is designed for long-term outdoor exposure and does not require scheduled re-coating; only minor scratches may need touch-up.

Which component reaches its load limit first when snow builds up on the roof?

The galvanised steel roof panels and aluminium frame are engineered to shed snow quickly, so snow load is the first limiting factor rather than a specific component failure.

How much heat builds up inside when the PE screens stay closed all day in full sun?

The movable PE screens can be slid open to vent heat; with them closed the enclosure traps solar gain, so opening panels is the main way to control temperature.
