Can it be fitted onto an existing wall or kerb?

Yes, on base plates bolted down where the substrate is sound. We check what is actually under the surface first, because bolting a two metre fence to a thin slab moves the failure from the fence to the concrete.

Does it need maintenance?

A wash and an occasional check on the hinges and fixings. There is no annual repainting on a galvanised and powder coated line, which is where the cost comes back compared with timber.

What height should a perimeter vertical bar fence be?

It depends on what you are protecting, but 2000mm to 2400mm is the usual range for a site perimeter, and below about 1800mm it stops being a deterrent. We will tell you honestly if the height you have asked for will not do the job you have described.

Should the tops be pointed or blunt?

Pointed heads deter climbing and are common on perimeters. Blunt heads are used where the public, and particularly children, are close to the line. The right answer depends on who is on each side of the fence.

How is vertical bar different from palisade?

Palisade uses wide profiled pales bolted to rails and reads as an industrial barrier. Vertical bar uses round or square bars through rails and reads as architectural. Palisade is usually cheaper at height; vertical bar is usually specified where the boundary is visible to the public.

Is access a problem for vertical bar fencing around EN6?

It is planned rather than discovered. Deliveries come in off A1000 Great North Road, and where a street near Potters Bar (Great Northern) is tight we arrange the offload and the carry before the start date so nobody spends the morning blocking a road.

Vertical bar fencing in Potters Bar

Vertical Bar Perimeters and Frontages in Potters Bar

The workhorse steel boundary: vertical bars through horizontal rails, sized from a light frontage run up to a genuine perimeter.

Vertical bar is the specification that scales. The same basic idea, bars passing through top and bottom rails, covers a 900mm run across a communal frontage and a 2400mm perimeter around a substation, and the difference between them is section size, bar centres and head detail rather than a different product.

That is why it is the most specified metal fence in the country and the one most often bought wrongly. A light domestic section put on a perimeter looks the part and bends the first time a wheelie bin is dragged into it.

We price the section rather than the picture. Tell us what the boundary has to resist and how often it gets hit, and the bar diameter, the rail size and the post centres follow from that.

Local notes for Potters Bar

Vehicle movement decides gate sizing on most Potters Bar sites. We check the swept path against the access off A1000 Great North Road and the turning available inside the gate line before quoting a leaf width, because a gate that cannot be opened fully in practice is a gate that gets left open.

The vertical bar work around Potters Bar splits cleanly: light runs on communal frontages, and heavier sections around Cranborne Industrial Estate. They are quoted as two different products because they are two different products, and pricing them off one rate per metre is how a boundary ends up under specified.

Many gardens border the green belt — the brief usually needs sturdy stock-proof boundary work, which is why post holes on taller runs here get sized to the exposure rather than to a standard depth. On a 2400mm line the foundation is the fence.

Specification at a glance

Typical height: 900mm frontage runs up to 2400mm perimeter lines
Head detail: Blunt top, pointed top or extended bar above the top rail
Bar centres: Set to the brief, closed up where climbing or through reach is the concern
Rails: Two rails as standard, three where height or impact loading calls for it
Finish: Hot dip galvanised then powder coated for the full section, welds included

On tall runs the galvanising is not optional. A powder coat alone over bare steel will fail at every drilled hole and weld within a couple of winters, and once it starts you are repainting the whole line.

Who buys this and why

Site perimeters, yards, substations, pumping stations and utility compounds
Communal frontages where a mesh line would look institutional
Boundaries beside parking where vehicles will occasionally make contact
Anywhere the boundary has to be seen through for surveillance

If the brief is privacy, vertical bar fails it completely. It is a see through boundary and it always will be. It is also more expensive per metre than weld mesh at the same height, so where appearance genuinely does not matter, mesh is the better value answer.

From visit to handover

1. Survey the line
Levels, existing kerbs, drainage runs and vehicle swept paths are checked before section sizing, because a gate that fouls a kerb is a redesign not a snag.
2. Foundations
Post holes sized to the height and the exposure, concreted, with deeper settings where the run is tall or the ground is soft.
3. Install and hand over
Bays fitted, welds and cut ends made good, and a written record of the specification handed over with the invoice.
