Security Fencing — Letchworth Garden City, SG6
Security fencing is a design problem before it's a materials problem — height, topping, sightlines and what sits either side of the line matter more than the panel you pick.
Letchworth Garden City's mix of the world's first garden city — arts and crafts cottages, planned terraces and consistent street trees means security fencing briefs vary street by street — d-section pales have a rounded face that offers less finger and foot grip than a flat pale, while W-section pales fold the steel into a shallow trough shape that resists bending under a lever without adding weight. Wilbury Road, Hillshott Letchworth Garden City station Hillshott's Arts and Crafts terraces date from the town's earliest development phase. Letchworth Garden City was the first garden city, and its layout and architecture are protected through covenants overseen by the Letchworth Garden City Heritage Foundation.
Why this comes up in Letchworth Garden City
North Hertfordshire District Council covers planning here, and vehicle and impact loading on perimeter fencing gets checked on every enquiry from this postcode. Where impact is a realistic risk, a kerb, bollard or heavier-gauge post is used to take the hit rather than relying on the fence panel itself to absorb it. Sollershott West and Nevells Road form part of the original 1903 masterplan and are subject to the Foundation's design guidance.
Access and material handling on site
Concrete, posts and panels are heavy, and a site with only a narrow side return or no vehicle access changes how a job is priced and sequenced — materials sometimes have to be carried through rather than dropped at the boundary.
On a commercial yard the opposite problem applies: keeping a working site operational around a delivery of steel palisade or mesh panels needs a delivery and storage plan agreed before the first post goes in.
Palisade pale profiles: D-section versus W-section
D-section pales have a rounded face that offers less finger and foot grip than a flat pale, while W-section pales fold the steel into a shallow trough shape that resists bending under a lever without adding weight.
W-section is the more common choice on a taller or higher-security run because the fold adds stiffness across the pale's width, whereas D-section is often reserved for lower, more decorative palisade work.
Vehicle and impact loading on perimeter fencing
A boundary next to a car park, loading bay or farm track needs posts and panels sized for accidental impact loading, not just wind and climbing loads, because a reversing vehicle applies a very different force to the same run.
Where impact is a realistic risk, a kerb, bollard or heavier-gauge post is used to take the hit rather than relying on the fence panel itself to absorb it.
Earthing and bonding requirements for a substation compound fence
A metal fence around an electrical substation compound needs to be correctly bonded to the site's earthing system, since an ungrounded metal fence near live electrical equipment can become dangerously energised under fault conditions.
Bonding work at a substation compound is carried out to the network operator's own specification rather than a general fencing standard, and a fencing contractor working on this type of site coordinates closely with the operator's engineers on sequencing and isolation.
Combining a low concrete plinth wall with fencing above
A low block or concrete plinth wall under a fence panel raises the effective height, resists dig-under and impact better than a timber gravel board, and gives a clean, level starting line on sloped or uneven ground.
The plinth needs its own foundation independent of the fence posts above it, since settling of one shouldn't be allowed to drag the other out of line.
Fixing new fencing to existing walls and piers
Bolting a new fence panel or post bracket to an existing wall or brick pier depends on the wall's own condition — a soft or unstable pier can't safely take the lateral load a fence puts on a fixing point.
Where a wall is sound, resin-fixed bolts into brick or masonry give a secure end point without a new post footing; where it isn't, a freestanding post just inside the wall line is the safer option.

Frequently asked
Will a solid fence make sightlines worse for security?
It can — a fence that blocks the view for an intruder can equally block it for you, which is why we assess sightlines from both directions, not just from inside the garden. Icknield Way, Broadway Howard Park Letchworth Garden City was the first garden city, and its layout and architecture are protected through covenants overseen by the Letchworth Garden City Heritage Foundation.
Is a CCTV warning sign a legal requirement?
Signage needs to be truthful and visible from the approach it warns about; a sign for a feature that doesn't exist offers no legal protection and can be misleading.
How do you fit a fence neatly against stepped brickwork?
Infill panels or a scribed timber closer are cut to follow the step on site, since older brickwork steps are rarely uniform enough to use a standard offset. Icknield Way follows the route of the ancient Icknield Way trackway, and chalk geology sits close to the surface along much of its length.
Can mesh and timber be combined on one boundary?
Yes, and it's a common approach — solid timber where privacy matters, mesh or railing where an open sightline is more useful.
Why do security gates use shear-nut bolts?
A shear-nut bolt snaps its head off once tightened, leaving nothing for a spanner to grip from outside, which stops fixings being undone at pale or panel junctions.
Does chain-link or weld mesh need re-tensioning over time?
Yes, ground movement and post settlement slacken mesh over a season or more, so re-tensioning via the straining wire is a routine maintenance task on older runs.
Can you make an existing fence more secure without a full rebuild?
Sometimes — adding anti-climb capping, closing gaps at gate junctions, or heightening a low section can be done without rebuilding the whole run if the posts are sound.
Should I record where a new boundary line sits after installation?
Yes, noting post positions relative to a fixed point helps avoid a future dispute if the new line differs slightly from where the old fence originally stood.
