Wire Balustrade Systems

Wire Balustrade Systems: Contemporary Cable Balustrades in 316 Stainless Steel

Our stainless steel wire balustrade systems create clean, contemporary barriers with almost no visual obstruction — slim 3mm cables tensioned between 48.3mm stainless steel posts, topped with a matching stainless handrail. Every component is 316 marine-grade stainless steel, so the system keeps its looks through UK weather, including coastal locations, with next to no maintenance. Want everything in one order? The Build Your Own wire balustrade kit is priced per linear metre and we confirm your exact layout with you.

Wire balustrades are designed for low-level applications with fall heights of 600mm and below — defining the edge of decking, garden terraces, patios and steps where a full guarding barrier isn't required by building regulations. For balconies, roof terraces and any raised area with a drop above 600mm, our glass balustrade systems and aluminium balustrade range are the right choice — see "Where is a wire balustrade suitable?" below.

What Is a Wire Balustrade System?

A wire balustrade uses horizontal stainless steel cables tensioned between posts to form a barrier you can barely see. Each 48.3mm post comes with a welded base plate and pre-installed saddle for the handrail; the 3mm wire rope threads through eyebolt connectors and is tensioned with swageless turnbuckle fittings — no specialist swaging tools needed. With the 48.3mm stainless handrail tube fitted, the finished height is 1100mm.  Wire balustrade is also known as cable railing — particularly for decks — and the system works the same way whichever name you know it by.

The wires sit at 132mm centres — 14-hole posts (7 holes each side) serve mid-run and corner positions, and 7-hole posts start and end each run.

Where Is a Wire Balustrade Suitable?

Honest answer: wire balustrade is a low-level system. UK building regulations require guarding wherever there's a drop of more than 600mm, and guarding infill must prevent a 100mm sphere passing through any gap. With wires at 132mm centres, this system is not designed to meet that infill requirement — so we recommend it for fall heights of 600mm and below, where guarding isn't mandated: deck edges close to ground level, garden terraces, path and border definition, and low steps.

If your project involves a balcony, raised decking or any drop above 600mm, choose a system designed for full guarding instead — our Build Your Own aluminium balustrade kit or our glass balustrade systems.

The Advantages of a Wire Balustrade

For the right setting, nothing else looks like it. The slim cables all but disappear at a distance, preserving views and light in a way solid infill can't. The 316 marine-grade stainless steel resists corrosion even in coastal spots, there's nothing to paint or treat, and the swageless fittings mean the whole system can be installed and re-tensioned with basic hand tools. It suits modern homes, garden studios, landscaping schemes and commercial grounds where a crisp, architectural edge is wanted without a visual barrier.

What's in the Range

Wire Rope Posts — 48.3mm, 316 Stainless Steel

Every post is 48.3mm diameter 316 stainless steel with a welded base plate and a pre-installed saddle ready for the handrail tube. 7-hole posts start and end each run. 14-hole mid posts (7 holes each side) sit along straight runs, and 14-hole corner posts carry the wires around a change of direction. We recommend spacing posts at 1.5m to keep the wires taut and sag-free.

Stainless Steel Wire Rope — 3mm

316 marine-grade 3mm wire rope, supplied in 10m, 50m and 100m lengths so you can buy what your runs actually need.

Handrail — 48.3mm Stainless Tube

The system is finished with a 48.3mm stainless steel handrail tube that sits in the saddles on the post tops, giving a comfortable rail and a finished height of 1100mm. A matching set of rail fittings completes it: raised end caps, an in-line connector for joining lengths, a wall flange for runs ending at a wall, and an adjustable elbow for steps and slopes.

Connectors & Fittings

Swageless turnbuckle connectors tension each wire with fine adjustment — no swaging tools required. Swageless plain buckle connectors terminate runs where adjustment isn't needed. Eyebolt connectors anchor the wire at the posts, locking collars secure the wire inside the fittings, and the 48.3mm post fitting adaptor ring gives a clean transition at the post. All fittings are 316 stainless steel.

Installing and Tensioning a Wire Balustrade

Plan your runs first: mark post positions at 1.5m spacings using a string line, fix each post plumb into solid structural material, then thread the wires from the start post through the mid posts to the far end. Tension each wire with its turnbuckle connector, working from the bottom wire up, until every wire is taut with no visible sag — then re-check the first wires, as tensioning later runs can slacken earlier ones. Give the system a final check a few weeks after installation and re-tension if needed; the turnbuckles make this a two-minute job. For help planning a layout, call the team on 01282 526428.

What is a wire balustrade system?

A wire balustrade uses horizontal 3mm stainless steel cables tensioned between 48.3mm posts, finished with a stainless handrail tube at 1100mm. The slim cables create a barrier with almost no visual obstruction, making it a popular contemporary choice for garden and landscaping projects.

Where is a wire balustrade suitable?

Wire balustrade is a low-level system, best suited to fall heights of 600mm and below — deck edges near ground level, garden terraces, borders and low steps. For balconies, raised decking or any drop above 600mm, UK building regulations require full guarding, and our glass and aluminium balustrade ranges are designed for that job instead.

Wire balustrade regulations UK — do wire balustrades meet guarding requirements?

Where a drop exceeds 600mm, regulations require guarding whose gaps prevent a 100mm sphere passing through. This system's wires sit at 132mm centres, so it isn't designed to meet that infill requirement — which is why we recommend it for low-level settings where guarding isn't mandated. If you're unsure what your project requires, check with your local building control, or call us on 01282 526428 and we'll recommend the right range.

How far apart should the posts be?

We recommend posts at 1.5m spacings. This keeps the wires taut between supports and prevents sagging. Keep individual runs to a sensible length and start a new run for very long stretches so tension stays easy to maintain.

How do I tension the wires?

Each wire is tensioned with a swageless turnbuckle connector — thread the wire, secure it with the locking collar, and turn the buckle body until the wire is taut with no visible sag. Work from the bottom wire up and re-check the first wires when you finish. No swaging tools are needed, and the same fittings let you re-tension in minutes at any time.

Do wire balustrades need maintenance?

Very little. Check the wire tension periodically — especially after the first few weeks and after extreme weather — and re-tension via the turnbuckles if any wire shows sag. An occasional rinse with fresh water keeps the 316 stainless steel bright, particularly in coastal locations.
