Step 1 – Placing the First Post

Place your first post in the desired location. Ensure you are using the pedestal-mounted posts on suitable flooring types, such as concrete, wood, etc.

Use a pencil to make a mark on the floor where the holes are in the base of the post. This is where you will drill into the floor.

Use a drill with a drill bit that is suitable for your flooring type to drill holes into these marked areas.

Place your post over the holes, lining them up with the holes in the base of the post. Secure your expansion screws that are provided with your order into the holes and floor underneath.

Use the plastic cover provided in your order to cover over the bottom of the pedestal, covering the screws for a more aesthetically pleasing finish.

Step 2 – Placing the Second Post

Place the 180cm U channel on the floor where you want your fence to line up, and measure where the second post needs to be installed. Ensure everything is straight using a spirit level and remove the U channel. Follow step 1 to install the second post.

Step 3 – Installing the Slats

Place the 180cm U channel at the base by sliding it down the channels in the posts.

Ensuring the pointed edge of the slat is at the top, slide the slat down the two posts, ensuring it is in place at either side, slotting comfortably into the channels of the posts.

Guide the slat all the way to the bottom, ensuring it sits in the U channel you placed previously.

Continue to do this with all of your slats until you reach the desired height, slotting their grooves into one another for a secure finish.

Step 4.1 – Finishing Without Screens

If you are NOT installing any fence or decor screens, place another U channel at the top of the fence slat to ensure a finished look.

Place the L bracket on top of the U channel in the posts on both sides, tightening the screws to hold the slats in place.

Step 4.2 – Finishing with Screens

Instead of finishing off the tops of your slats with the U channel and L bracket, you may decide you want a decorative screen to sit on top. If this is the case, slide your H channel on top of your last slat, and then your screen slots into this. Secure the screen in place with an L bracket on either side.

The panels are constructed from deep black wood effect slats, providing a modern, minimalist aesthetic while mimicking the texture and grain of natural wood. Sturdy black posts frame each fence panel, and a horizontal slatted topper sits above, offering a stylish, semi-private finish that adds visual interest and allows airflow and light to pass through. The fence is installed on a clean concrete base and surrounded by neatly maintained glass, with a backdrop of lush greenery and trees, highlighting how this fencing design can enhance a sophisticated garden or outdoor living space.

How to Install Composite Fencing with Buried Posts:

You will need:

  • Spirit level
  • Tape measure
  • Shovel
  • Concrete

Step 1 – Placing the First Post

Determine where your first post needs to be installed to get going with the installation.

Dig out a hole in the ground that is 50cm deep and wide enough for the post to fit with a little wiggle room on either side.

Mix up your concrete and pour this into the hole, ensuring your post is held straight with a spirit level, keeping it in position until the concrete dries.

Step 2 – Placing the Second Post

a) Place the U channel at the bottom of your post

b) Measure where your second post needs to sit at the end of this 180cm U channel.

c) Remove the U channel and install the second post following step 1, where you measured.

Ensure all your concrete is completely dry before beginning the installation of the slats.

Step 3 – Installing the Slats

Place the 180cm U channel at the base of the two posts.

Ensuring the pointed edge of the slat is at the top, slide the slat down the two posts, ensuring it is in place at either side, slotting comfortably into the posts themselves.

Guide the slat all the way to the bottom, ensuring it sits in the U channel you placed previously.

Continue to do this with all of your slats until you reach the desired height, slotting their grooves into one another for a secure finish.

Step 4.1 – Finishing Without Screens

If you are NOT installing any fence or decor screens, place another U channel at the top of the fence slat to ensure a finished look.

Place the L bracket on top of the U channel in the posts on both sides, tightening the screws to hold the slats in place.

Step 4.2 – Finishing with Screens

Instead of finishing off the tops of your slats with the U channel and L bracket, you may decide you want a decorative screen to sit on top. If this is the case, slide your H channel on top of your last slat, and then your screen slots into this. Secure the screen in place with an L bracket on either side.

The fence is set on a concrete base surrounded by neatly trimmed grass, framed by lush green trees in the background, illustrating how this design combines functionality with elegant garden styling.

How to Install Composite Fencing with Existing Concrete Posts:

You will need:

  • Tape Measure

Step 1 – Measure Up

Before beginning installation, we recommend you measure the distance between your existing concrete posts to ensure this matches the length of our slats. This should be 180cm.

If the distance between your posts doesn’t match that of our slats, you will need to cut them. Follow our guidance on how to do this.

Step 2 – Slat Installation

Place the side channel adaptors on either side of your concrete posts, sliding the bottom U channel into these and guiding them to the base of your posts.

Ensuring the pointed edge of the slat is at the top, slide the slat down the two posts, ensuring it is in place at either side, slotting comfortably into the side channels themselves.

Guide the slat all the way to the bottom, ensuring it sits in the U channel you placed previously.

Continue to do this with all of your slats until you reach the desired height, slotting their grooves into one another for a secure finish.

Step 3.1 – Finishing Without Screens

If you are NOT installing any fence or decor screens, place another U channel at the top of the fence slat, to ensure a finished look.

Place the L bracket on top of the U channel in the posts on both sides, tightening the screws to hold the slats in place.

Step 3.2 – Finishing with Screens

Instead of finishing off the tops of your slats with the U channel and L bracket, you may decide you want a decorative screen to sit on top. If this is the case, slide your screen on top of your last slat and secure it in place.
