Composite Fence Kit - with Wave Trellis

Composite Garden Fencing Details

Premium composite fencing designed to create a modern, low-maintenance garden. Our composite fencing combines durability, attractive contemporary styling and excellent resistance to everyday outdoor weather conditions.

Available in a range of colours, heights and installation options, the system can be configured to suit both new fencing projects and existing concrete post installations.

Before After

Installation Options

Step 1

Clean & Paint

Clean the concrete posts and give them a fresh coat of paint for a neat finish

Step 2

Fit the inserts

Place an insert into the groove of each concrete post, on both sides.

Step 3

Fit the bottom rail

Slot the bottom rail in between the two inserts so it sits on top of your concrete gravel board, spanning the gap between the posts.

Step 4

Stack the fence boards

Fit the first fence board into the bottom rail with the groove facing down, then stack the remaining boards on top of it.

Step 4a

(Trellis kits only)

Fit the H-channel on top of the fence to connect to the trellis topper.

Step 5

Fit the top rail

Push an L-shaped clip into each end of the top rail, then lower the top rail onto the stack of fence boards (or the trellis topper, for trellis kits) so the clips drop down into the inserts.
(Curved trellis only) – Skip this step, as the top rail is flat and won't sit on a curved trellis.

Step 6

Secure the top rail

Using self-drilling screws, screw through each L-shaped clip into the insert below it.

Step 6a

(Curved trellis only)

There's no top rail to secure. Instead, screw one side of the L-shaped clip directly onto the trellis with an extra screw, then screw the other side of the clip into the insert.

Step 7

Cap the posts

apply a bead of silicone glue and fix the caps onto the top of the inserts.

Step 1

Mark out post positions

1. Measure and mark the post centres according to your panel width, keeping spacing even.
2. Run a taut string line between stakes to keep the run straight.
3. Mark each post position clearly on the hard surface (paving, concrete or tarmac) before drilling.

Step 2

Position the mounting plate and drill

1. Hold the mounting plate at each marked position, checking it's square to the string line.
2. Mark the 4 bolt-hole positions through the plate onto the surface below.
3. Drill each hole to the diameter and depth specified for your expansion bolts, then clear away any dust or debris.

Step 3

Fit expansion bolts and secure the plate

1. Tap an expansion bolt into each drilled hole until it sits flush with the surface.
2. Place the mounting plate over the 4 bolts.
3. Fit the washers and nuts, then tighten evenly in a diagonal sequence to draw the plate down flat and secure.

Step 4

Fit and plumb the post

1. Slot the aluminium post onto the mounting plate.
2. Fix the post to the plate using the screws or bolts supplied for that joint.
3. Check the post is plumb (vertical) on all sides with a spirit level before moving on.

Step 5

Repeat for remaining posts

1. Set every post along the run first.
2. Check the spacing and alignment between posts before moving on.

Step 6

Fit bottom rail

1. Slot the bottom rail between the post grooves at ground level.
2. Make sure it is seated level between the two posts.

Step 7

Fit composite boards

1. Slide the first composite board groove-down into the bottom rail.
2. Continue stacking boards upward, sliding each edge into the post channel as you go.
3. Apply silicone to board/rail joints if desired.

Step 8

Fit H-channel

1. Fit the H-channel on top of the final fence board.
2. This connects the panel to the trellis topper.
3. Skip this step if your kit has no trellis topper.

Step 9

Fit top rail

1. Fit the L-clips into the top rail ends — long leg inserted horizontally into the rail, short leg pointing upward.
2. Lower the top rail onto the boards (or trellis topper).

Step 10

Secure top rail

1. Screw through the L-clips into the post channel to secure the top rail.
2. For curved trellis kits, screw one side of the L-clip onto the trellis with an extra screw, then screw the other side into the post.

Step 11

Fit post caps

1. Fit the caps directly onto the tops of the aluminium posts.
2. No glue or silicone is needed — the caps press on securely by themselves.

Step 1

Mark out post positions

Measure and mark the post centres
according to your panel width, keeping
spacing even.
Run a taut string line between stakes
to keep the run straight.
Mark each post position clearly along
the line before digging.

Step 2

Dig post holes

Dig a hole at each marked position, approximately 2 ft (600 mm) deep.
On waterlogged ground, add a layer of hardcore or rubble to the base for drainage.

Step 3

Set the aluminium post

Stand the post in the hole.
Check it is plumb (vertical) on all sides with a spirit level.
Brace it with temporary props or battens to hold it in place.

Step 4

Pour and set concrete

Mix and pour concrete around the post, working it in to remove air pockets.
Re-check the post is plumb before the concrete begins to set.
Leave to fully cure — typically 24–48 hours — before continuing.

Step 5

Repeat for remaining posts

Set every post along the run first.
Check the spacing and alignment between posts before moving on.

Step 6

Fit bottom rail

Slot the bottom rail between the post grooves at ground level.
Make sure it is seated level between the two posts.

Step 7

Fit composite boards

Slide the first composite board groove-down into the bottom rail.
Continue stacking boards upward, sliding each edge into the post channel as you go.
Apply silicone to board/rail joints if desired.

Step 8

Fit H-channel (trellis kits only)

Fit the H-channel on top of the final fence board.
This connects the panel to the trellis topper.
Skip this step if your kit has no trellis topper.

Step 9

Fit top rail

Fit the L-clips into the top rail ends — long leg inserted horizontally into the rail, short leg pointing upward.
Lower the top rail onto the boards or trellis topper.

Step 10

Secure top rail

Screw through the L-clips into the post channel to secure the top rail.
For curved trellis kits, screw one side of the L-clip onto the trellis with an extra screw, then screw the other side into the post.

Step 11

Fit post caps

Fit the caps directly onto the tops of the aluminium posts.
No glue or silicone is needed — the caps press on securely by themselves.
