Aluminium garden posts with slot: sleek and strong for composite fences

A durable fence starts with a sturdy base. With aluminium garden posts with a slot you can mount composite planks neatly and stably, without the hassle of crossbeams or visible fixings. Ideal for a modern garden, new-build projects, and commercial properties.

Why choose aluminium slotted posts?

Sleek appearance: planks slide into the slot, with no visible screws.
Dimensionally stable: aluminium expands and contracts less than wood and remains straight.
Durable: suitable for all weather conditions.
Modular: easily adaptable for custom work and corners.

What types of aluminium garden posts are there?

For a neat and sturdy installation, use the correct type of post for each situation. Usually, you'll need a combination of:

Intermediate post

For straight sections between two fence sections. This is the most commonly used post.

Corner post

For corners and L-shapes. Ensures a neat connection from two directions.

End post

For the beginning or end of a fence line.

Installation: placing aluminium posts in concrete

Step 1: Lay out and drill holes

Mark out the line accurately with string. Drill or dig holes deep enough for stability (often 80–90 cm, depending on post length and ground conditions).

Step 2: Leveling

Place the post level and temporarily fix it. A correctly positioned first post determines the entire result.

Step 3: Quick-setting concrete and curing

Fill around the post with quick-setting concrete and allow it to cure sufficiently before mounting the planks.

What post length do you need?

The correct length depends on your desired fence height and the depth in the ground. A practical rule of thumb: the higher the fence, the deeper and sturdier the foundation needs to be.

Standard garden heights usually require solid placement in concrete.
In windy locations, extra depth or reinforcement is advisable.

Common mistakes with slotted posts

Too little attention to leveling (crooked line = crooked fence)
Not placing the post deep enough
Not taking into account corner and end posts
Working too quickly without concrete curing

Frequently asked questions

Are aluminium slotted posts suitable for every garden?

Yes, in almost all situations. In very soft ground, extra foundation or reinforcement is recommended.

Do I need crossbeams with a slotted system?

No, with a slotted system, you slide the planks directly into the posts. This gives a sleek finished result.

Can I combine slotted posts with fence panels?

That depends on the chosen system. Modular systems work most logically with slotted posts. For complete panels, other fixings are often used.
