Slotted Concrete Fence Posts, Intermediate, End and Corner, 5ft to 10ft, Steel Reinforced

These slotted concrete fence posts are for contractors, landscapers and homeowners putting up or replacing a closeboard fence. Each post is dry-cast concrete with steel reinforcing rod centres, and the slots take closeboard panels and concrete gravel boards without nails, brackets or fixings: the panels simply slide into place. Use intermediate posts on straight runs, corner posts where the fence turns and end posts where a run finishes. If you are tired of timber posts rotting at ground level, concrete resists rot, rust and moisture, in a plain light grey that sits quietly behind planting.

Why it works

Dry-cast concrete with a steel centre

The concrete gives each post its mass and weather resistance, while steel reinforcing rods run through the centre. Strength and load figures are not published for this line, so size your posts with the pairing guide below rather than a rating.

Resists rot, rust and moisture

Timber posts usually fail where they meet wet ground. Concrete resists rot, rust and moisture, so there is no preservative to reapply to the posts. It is a low maintenance alternative to timber, not a no-maintenance one: your timber panels still need their usual care.

Slots instead of fixings

Panels and gravel boards slide into the slots, so nothing needs nailing or bracketing to hold them. A damaged panel can later be lifted out and replaced without disturbing the post.

A clean, even finish

The light grey posts have a smooth finish with minimal surface bubbles, so a long run looks consistent from post to post.

Where it's used

Garden boundaries between neighbouring properties, where a 6ft closeboard fence is the usual choice. Replacement jobs, where rotted timber posts are swapped out along an existing line. New-build and renovation plots, where the contractor wants a fence that needs little attention after handover. Side passages and driveway boundaries, wherever panels sit on concrete gravel boards to keep the timber off the soil.

Specifications

Choosing the right option

Start with the layout. Intermediate posts, with two opposite slotted sides, go between panels on a straight run. Corner posts, with two adjacent slotted sides, take panels at a right angle where the fence turns. End posts, with one slotted side, finish a run. Then match post length to panel height: 6ft post with a 3ft panel, 7ft with 4ft, 8ft with 5ft, and 9ft with a 5ft 6in or 6ft panel. A pairing for 5ft and 10ft posts is not published for this line. Note that end posts are only available here in 7ft, 8ft and 9ft, and corner posts in 8ft, 9ft and 10ft; other end and corner heights are currently unavailable.

Installation, use & care

Set roughly one-third of the post length below ground, so an 8ft post needs a 2ft hole. For standard 6ft-wide panels, space posts at 1.83m centres. Set each post in post mix concrete and prop it until the mix starts to set. As a guide, allow 1 bag per post for 5ft and 6ft posts, 1.5 bags for 7ft and 8ft, and 2 bags for 9ft and 10ft; the amount varies with hole size. Concrete posts are heavy and brittle if dropped on a corner, so handle each one with two people.

FAQ

What length of post do I need for a 6ft fence?

Use 8ft posts with 5ft panels sitting on 1ft (305mm) concrete gravel boards. Around a third of the post goes below ground, so each 8ft post sits in a 2ft hole and leaves 6ft of fence above ground.

Do I need brackets or screws to hold the panels?

No. Panels and concrete gravel boards slide into the slots, so no nails, brackets or fixings are needed to hold them. Order the right post type for each position so every panel has a slot on both sides.

Can I get end or corner posts in 5ft or 6ft?

Not on this listing. End posts come in 7ft, 8ft and 9ft, and corner posts in 8ft, 9ft and 10ft; other end and corner heights are currently unavailable. Intermediate posts are available in every height from 5ft to 10ft.

Ordering & delivery

Posts are priced per post as listed; choose the type and height from the options. Delivery is to UK mainland addresses. The posts are heavy, so they travel on a pallet to kerbside: plan for two people to unload them. Your lead time is confirmed at checkout or on your order confirmation.
