Anti-climb mesh (358)

Very close welded mesh that's hard to climb or cut. For high-security sites.

Anti-climb temporary panel

A temporary fence panel with close mesh that's harder to climb.

Base plate

A steel plate on the foot of a post, so it can be bolted to a concrete base instead of dug in.

Bay

One section of fence between two posts. A Palisade Standard bay at HERMEQ is 2.75 m.

Corner post

A post used where the fence changes direction.

Coupler (fence clip)

The clamp that joins two temporary panels together.

D section pale

A rounded pale. Still specified on some public projects and for matching older fences.

Exempted development

Work that doesn't need planning permission, within set limits. Around a house, metal palisade and security fences aren't covered.

Fence foot

The heavy rubber or concrete block a temporary panel's legs stand in.

Fishplate

A flat steel plate that joins rails end to end.

Galvanised

Steel coated in zinc to protect it from corrosion. The working finish for industrial sites.

Inter post

A post between bays in a straight run.

Pale

One vertical upright in a palisade fence.

Palisade fencing

A steel security fence of vertical pales bolted to horizontal rails between posts.

Postcrete

A dry concrete mix for setting posts that needs no mixing.

Powder coated

A baked-on colour finish, applied over galvanising on security fencing, giving two layers of protection.

Rail

A horizontal bar the pales bolt to. A Standard palisade bay has a top and a bottom rail.

Section 5 declaration

A formal decision from your council on whether a project is exempted development. In Clare: form P07, a site map and an €80 fee.

Strut (stay)

A brace from a temporary fence to a ballast block, to stop it blowing over.

Triple-point splayed head

A pale top with three points bent outwards. The hardest palisade head to climb over.

Twin wire mesh (656, 868)

Panels with two horizontal wires either side of each vertical. 868 uses heavier wire than 656.

V mesh

Welded wire mesh panels with V-shaped folds for stiffness. For general boundaries.

W section pale

A pale folded into a corrugated W shape, which adds strength. The usual pale on new fences.
