GRP Handrails, Guardrails & Edge Protection Systems
GRP handrail systems provide a corrosion-resistant alternative to traditional steel barriers and safety railings. Manufactured from pultruded GRP tube and moulded connection fittings, they can be configured to create handrails, guardrails, edge protection systems and pedestrian barriers for industrial, commercial and infrastructure environments.
The modular design allows sections to be cut, assembled and modified on site without welding, hot works or specialist fabrication equipment.
Common applications include industrial platforms, rooftop walkways, water treatment facilities, transport infrastructure, marine environments and public access routes.
Types of GRP Handrail
Platform & Walkway Guardrails
Top rail and knee rail guarding for platforms, walkways and mezzanines.
Stair & Ramp Handrails
Adjustable angle fittings follow the slope of stairs and ramps without cutting or mitring.
Rooftop Edge Protection
Guardrails around roof edges, plant areas and openings where people work at height.
Pedestrian Barriers
Separate walkways from vehicles, machinery and hazardous areas. High-visibility yellow is easy to see.
Steel Handrail Replacements
GRP fitted to the existing layout where steel has corroded, with no welding or hot works on site.
Yellow GRP Fittings
The bends, tees and base plates that make up a modular system, available on their own for repairs and extensions.

Corrosion Resistance & Maintenance Requirements
Unlike steel handrails, GRP does not rust and does not require galvanising, painting or ongoing corrosion treatment. This makes it particularly suitable for coastal environments, water treatment facilities, chemical processing sites and external infrastructure projects where long-term durability is important.
The material is pigmented throughout the profile, helping to maintain appearance even where surface abrasion occurs during normal use.
GRP Handrail System Specifications
| Specification | Details |
|---|---|
| Tube Diameter | 50mm outside diameter |
| Wall Thickness | 5mm |
| Material | Pultruded GRP tube |
| Fittings | Moulded GRP connection fittings |
| Standard Colour | Safety yellow |
| Assembly Method | Mechanical fixings and structural adhesives |
Installation & Modification
The modular nature of the system allows handrails to be assembled using moulded fittings, mechanical fixings and structural adhesives. Sections can be cut and modified on site without welding or hot works, simplifying installation and future alterations.
This flexibility makes the system suitable for both new-build projects and the replacement of existing steel handrails.
GRP Handrail Connection Types
The modular system uses a range of moulded fittings to create straight runs, corners, junctions and changes in direction.
Connection Specifications
| Connection Type | Description |
|---|---|
| Stanchion Post Base Plate | Base plate for fixing stanchion posts to floors, platforms or walls; also used for wall connection points. |
| 4-Way Connection – Stanchion to Knee Rail | Connects vertical stanchion to both top rail and knee rail in one fitting. |
| 90 Degree Bend | Forms internal or external corners in the handrail run without cutting and mitring the tube. |
| Tee Connection | Creates T-junctions where rails intersect or where mid-rails meet a post. |
| Universal Angle Bend | Adjustable fitting that fits over the tube for ramps, stairs or changes in gradient. |

GRP Handrail — FAQs
It’s a barrier system made from pultruded GRP tube and moulded fittings that simply clamp together, providing a strong, corrosion-resistant alternative to steel key-clamp handrails.
GRP handrails offer excellent strength and impact resistance while avoiding rust and conductivity. For many industrial and access applications it provides comparable performance with lower maintenance.
On platforms, walkways, stairs, ramps, loading areas, chemical plants, water treatment works, marinas, rooftops and any environment exposed to weather or corrosive agents.
Yes. The modular fittings and universal angle bends allow rails to follow stair pitches, ramps and changes in level.
High-visibility yellow uprights and rails, combined with “warm to the touch” surfaces, support DDA-compliant handrail design when used with appropriate layouts and heights.
Stanchion posts are typically bolted to steel, concrete or GRP structures using base plates. Rails are clamped into moulded fittings which are then mechanically fixed and, if required, adhesive-bonded for extra security.
Yes. GRP systems are ideal as a direct replacement where steel has corroded or where non-conductive, low-maintenance systems are required.
