Security fencing
A clear, secure boundary that keeps your site protected. Our team makes and installs welded mesh, 358, palisade, vertical bar and temporary fencing for industrial sites, utilities, schools and construction, and where the perimeter has gates in it, we wire them up and automate them too.
Constructionline Gold and SSIP assessed, which matters when the fencing is going on somebody else's live site.
The fencing systems we install
Welded mesh
Rigid mesh panels on posts. The all-round commercial perimeter: clear sight lines through it, hard to cut quietly, and it doesn't look like a prison.
358 mesh
Mesh with apertures too small to get a finger or a standard tool into, which is why it's specified where climbing and cutting are the risks.
Palisade
Steel pales with pointed or rounded tops. Long established on utilities, substations and industrial boundaries.
Vertical bar
Bar fencing for perimeters that are on show as well as secure, where a mesh panel would look wrong.
Temporary and site hoarding
Perimeters for construction and phased works, where the line needs to move as the site does.
Mesh, palisade and screens
The sites that specify it
- Industrial and distribution. Long perimeters with vehicle gates in them, and a yard that needs keeping separate from the public road.
- Utilities and infrastructure. Substations, pumping stations, compounds and plant, where the fence is the only thing there most of the time.
- Schools and education. Perimeter and internal line fencing, with controlled pedestrian gates. Public sector and local authority.
- Construction sites. Hoarding and temporary line fencing, changed as the works phase through.
- Yards and depots. Where the fence, the vehicle gate and the access control all need to work as one entrance.
What a fencing specification actually has to settle
Choosing the right fence depends on more than the panel type. These are the things that change the job, and we'll talk you through each of them:
Height and topping
What the fence is keeping out, and whether anything sits on top of it.
Aperture
Whether the mesh needs to resist fingers and hand tools, which is the whole case for 358 over standard mesh.
Post fixing and ground conditions
Concreted, bolted down or driven, and what the ground will actually take.
Gates in the line
Pedestrian gates, vehicle gates, which way they swing or slide, and whether they'll be powered.
Wind load and exposure
On hoarding and solid infill in particular.
Working on a live site
Access, phasing, and how the perimeter stays secure while it's being replaced.
Where a specification calls up a published standard or a rated product, we work to it and provide the documentation. We don't make claims about a rating a product hasn't been tested to.
The perimeter is only as good as the entrance
There's little point specifying 358 mesh and then leaving a gate that anybody can push open. We make and fit the vehicle and pedestrian gates in the fence line, automate them where your site needs it, and wire the access control into the same system.
Made in our own workshop
Made-to-measure gates, frames and infill panels in a fence line come from our own facility in Berkhamsted rather than being bought in and adapted. Our factory production control for load bearing and welded structural steel is certified to BS EN 1090-1 and BS EN 1090-2 at execution class EXC2, certificate 2273-CPR-4271, valid to 21 August 2027.
Procurement. We hold Constructionline Gold, registration 00322439, assessed against the Common Assessment Standard, and SSIP via Once For All. We carry 8m pounds public liability and 8m pounds products liability. On framework and main contractor work, that's usually the paperwork asked for first, and we're happy to send it over.
Fencing keeps people out. Railings mark a boundary.
If what you'd really like is a boundary in front of a house, a front garden or an estate frontage, that's railings rather than security fencing, and we make those too.
Fence line, gates and access control
Priced, made and fitted as one job, with one company accountable for the entrance.
Common questions
What is 358 mesh, and when is it specified?
358 mesh is a welded mesh with a very small aperture, named after that aperture rather than the panel: 3 inches by 0.5 inches, in 8 gauge wire. The apertures are too small to get a finger or a standard hand tool into, so the panel is hard to climb and hard to cut quickly. It's specified where the assessed risk is people climbing or cutting the fence rather than simply walking round it, which is why you'll see it on utilities, secure compounds and some school perimeters.
Do you install fencing on live sites without closing them?
Yes, and it's most of what we do. Very few of the sites we fence can stop trading, teaching or operating while the line is replaced, so access, phasing and how the perimeter stays secure during the work are settled in the specification rather than on the day. In practice, we replace the line in sections rather than all at once, and where a stretch has to stand open, temporary fencing or hoarding holds the boundary until the permanent panels go in. We provide risk assessments and method statements before work starts, our engineers and core workforce are directly employed rather than subcontracted so you know who's on your site, and we're Constructionline Gold and SSIP assessed, which is usually the paperwork a live site asks for first. We'll work out the phasing with you before anybody attends.
