Bespoke GRP Access Stairs
Every GRP staircase system is designed around the operational requirements of the installation. Stair geometry, loading, landing arrangements, support locations and the operating environment all influence the finished structure, ensuring safe and reliable access throughout its service life.
Systems can be designed for rooftop plant, manufacturing facilities, water treatment works, utilities infrastructure, marine environments and other industrial applications. Depending on the project, staircases can be integrated with landings, access platforms, walkways, handrail systems and supporting steelwork to provide a complete access solution.
Typical Applications
GRP staircase systems are installed wherever permanent access is required between different working levels. Applications range from access to rooftop plant and production equipment through to elevated process areas, water treatment facilities and industrial infrastructure where corrosion resistance and low maintenance are important considerations.
Typical installations include water treatment works, manufacturing plants, chemical processing facilities, utilities infrastructure, commercial buildings, rooftop plant areas, rail infrastructure and marine environments.
Components of a GRP Staircase System
As a specialist fabricator of GRP access systems, we manufacture complete staircase assemblies rather than simply supplying individual products.
A typical staircase system may include:
Component | Purpose |
|---|
| GRP Stair Treads | Slip-resistant walking surface |
| Intermediate & Top Landings | Safe transition and resting areas |
| GRP Handrails | Personnel protection and guidance |
| Toe Plates & Kick Plates | Object retention and edge protection |
| Structural Steel Framework | Primary load-bearing support |
| GRP Flooring Panels | Landing and platform surfaces |
| Access Platforms | Safe working and maintenance areas |
| Fixings & Connections | Secure assembly and installation |
All elements are designed to work together as a complete access solution, providing both structural integrity and long-term reliability.
Why GRP Is Specified
GRP staircase systems are specified across industrial, commercial and infrastructure projects because they combine long-term durability with low maintenance requirements.
Unlike traditional steel structures, GRP does not rust and performs well in environments exposed to moisture, chemicals and external weather conditions. The material also provides excellent slip resistance through integrated anti-slip stair tread surfaces, helping improve safety for personnel using the access system.
The lightweight nature of GRP can simplify transportation, handling and installation while reducing loads imposed on supporting structures. In addition, GRP is non-conductive and offers low thermal conductivity, making it suitable for utility, electrical and specialist industrial environments.
These characteristics make GRP stair systems particularly suitable for water treatment facilities, manufacturing plants, marine environments, rooftop access systems and other applications where reliability and whole-life performance are important considerations.

GRP vs Steel Staircases
| Feature | GRP Staircases | Traditional Steel Staircases |
| Corrosion Resistance | Excellent | Requires coatings and maintenance |
| Weight | Lightweight | Significantly heavier |
| Maintenance | Minimal | Ongoing maintenance required |
| Slip Resistance | Integrated anti-slip surfaces | Additional treatments often required |
| Electrical Conductivity | Non-Conductive | Conductive |
| Lifecycle Cost | Low | Higher long-term maintenance costs |
For many industrial applications, these advantages can deliver significant operational and maintenance benefits over the lifetime of the installation.
