Used by self-builders, architects and main contractors who want to firm up the spec before talking to our team.
Each of the four systems below is a complete product on its own, designed for a specific application, with its own spec, install method and price band. Pick the one that fits your project.
4MM · 100MM CENTRES · POST-MOUNTED
Eight to ten parallel stainless wires running between square or round stainless posts. The classic specification, used on the majority of staircase and terrace projects.
4MM · 100MM CENTRES · TOP & BOTTOM RAIL
Vertical stainless wire infill between top and bottom rails. A clean, contemporary alternative to horizontal wire, suited to projects where a vertical line is preferred.
4mm · side-fixed · stair stringers
Stainless wire fixed directly to the wall or stair stringer, with no posts in front of the run. Slimmest visual profile of the four systems and a great retrofit option.
4mm · diy-friendly · made to measure
Easy to cut to length, pre-tensioned stainless wire kits for self-builders fitting their own balustrade. Includes wire, tensioners, posts and full installation guide. Quick despatch.
Every wire balustrade we supply is engineered to comply with BS 6180:2011 (barriers in and about buildings) and Approved Document K. Tension calculations are project-specific and signed off before fabrication.

Wire Balustrade Installation Guide
Pricing Guide For Wire Balustrade
One of SWR’s most ambitious installations to date.
UK building regulations (Approved Document K) require that balustrades on staircases are not easily climbable — particularly where children may be present. Horizontal wire creates a ladder-like pattern that can be climbed; vertical wires run top-to-bottom and do not. For staircase applications, vertical wire is the specification that satisfies Building Control without requiring additional justification. Horizontal wire can still be used on stairs, but vertical is the straightforward compliant choice.
SWR vertical wire systems use [X] wires across a standard bay, spaced at equal centres. Spacing is set to comply with the 100mm sphere rule — no gap in the infill should allow a 100mm sphere to pass through. Post spacing and wire count are confirmed at specification stage based on your run length.
Yes. Coated wires are available in a variety of colours for vertical wire systems — useful where the wire infill needs to complement a specific colour scheme or interior palette. Speak to the team at quote stage to confirm available colour options.
Yes. All SWR wire systems are available in AISI 304 or marine-grade 316 stainless to suit indoor, sheltered outdoor and exposed coastal applications. For outdoor use, 316 is recommended. For coastal or poolside installations, 316 is required.
No. Our balustrade systems are designed for easy fitting — a few design specifications are all it takes to create and install a unique wire rope infill system. Full installation documentation is provided with every order. For those who’d prefer not to install themselves, SWR offers supply-and-install for projects in the South East.
