FRP Stairs

Fibre Reinforced Polymer (FRP) stairs from Wagners Composite Fibre Technologies (CFT) provide a durable, high-performance pedestrian access solution designed for demanding public infrastructure, commercial and industrial environments. Engineered using advanced composite materials, FRP stairs deliver long-term strength. Our products provide reliable performance with lasting durability; they are corrosion-resistant, UV-resistant and require minimal upkeep.

Whether supporting coastal walkways, mining infrastructure, high-traffic outdoor applications, or environmental reserves, FRP stairs are designed to provide safe, reliable pedestrian movement while reducing lifecycle maintenance costs for asset owners.

Wagners’ FRP pedestrian stairs are custom-engineered to meet project-specific requirements, delivering structurally sound, compliant and aesthetically integrated infrastructure solutions built for decades of service life.

Proven Composite Solutions For Harsh Environments

Wagners has supplied composite infrastructure solutions across Australia and New Zealand, supporting projects in some of the region’s most challenging environments.

FRP stairs are particularly well-suited to coastal, marine, and chemically aggressive environments due to the non-corrosive and non-leaching nature of our composite materials. Unlike steel or timber stair structures, FRP stairs are inert and will not rot, rust or corrode.

From tidal zones and flood-prone landscapes to mining sites and high-traffic urban infrastructure, Wagners’ FRP stairs are engineered to maintain structural integrity and performance under continuous environmental stress.

Supported by in-house design, engineering and certification teams, Wagners works collaboratively with clients to develop stair systems that balance structural performance, safety compliance and visual design requirements.

Compliance and Design Standards

Wagners’ FRP stair systems are designed in accordance with recognised Australian standards and international structural and access standards, supporting specification confidence for engineers and infrastructure owners.

Design methodologies align with:

  • AS1657 — Design for access and mobility
  • AS2156 — Walking track and pedestrian infrastructure design
  • AS1170 — Structural design actions and load considerations

Compliance with these standards ensures FRP stairs provide safe access for pedestrians while meeting regulatory and procurement requirements for public infrastructure projects.

FRP Structural Design

FRP stair systems are designed using composite engineering principles guided by the EUROCOMP design methodology and structural design handbook.

Unlike traditional steel or concrete structures, where ultimate strength is often the governing design factor, FRP structures are typically governed by serviceability performance. This includes deflection control, vibration performance, and long-term creep deformation.

Due to the relatively lower modulus of elasticity of composite materials compared to metals, FRP stair components are carefully sized to ensure structural stiffness while maintaining substantial inherent strength reserves.

Engineers specifying FRP stair systems are encouraged to consider:

  • Long-term structural performance considerations
  • Connection detailing and joint behaviour
  • Long-term load and environmental exposure conditions
  • Dynamic pedestrian loading performance

Explore Wagners’ CFT design guides for detailed technical guidance.

Stair System Integration with Our FRP Products

FRP stairs are rarely designed as standalone components. Instead, they are part of a wider pedestrian access system that includes platforms, walkways and access structures.

Wagners’ FRP stairs can be integrated seamlessly with:

Using compatible composite materials across access systems ensures consistent slip resistance, load performance and environmental durability across the entire structure.

From a user experience perspective, integrated FRP systems provide:

  • Smooth and safe transitions between surfaces
  • Consistent underfoot performance
  • Reduced trip hazards and maintenance variation across different materials

For asset owners, system integration simplifies long-term asset management and improves lifecycle performance outcomes.

FRP Stair Customisation Options

Wagners offers a wide range of design and finish options to support project-specific performance, safety and aesthetic requirements. View all the specifications and details in our product guide.

Custom FRP Handrail Systems

Custom FRP handrail systems provide enhanced safety and accessibility performance for stair access infrastructure.

Handrail systems are engineered to:

  • Meet or exceed Australian accessibility and safety standards
  • Provide corrosion resistance in coastal and industrial environments
  • Deliver lightweight installation and long-term structural performance

FRP handrails provide an alternative to traditional metal systems, reducing maintenance requirements while maintaining structural reliability.

FRP Grating & Decking Options

Wagners’ FRP stair systems can incorporate multiple decking and grating configurations:

  • Micro-mesh decking: High pedestrian comfort and superior slip resistance
  • Mini-mesh decking: Balanced drainage and stability performance
  • Open-mesh decking: Maximum drainage and ventilation
  • Covertop decking: Solid surface aesthetic with high slip protection

These options allow designers to optimise performance based on site conditions and pedestrian traffic volumes.

Colour Choices and Coatings

Our colour palettes offer a broad range of premium and standard colour choices to suit natural, urban or industrial environments.

Two primary coating systems are used:

  • Fluoropolymer coatings for direct sunlight and marine exposure
  • High-quality polyurethane coatings for indirect sunlight and non-corrosive environments

These coatings provide UV protection, colour retention and enhanced surface durability.

Learn more about our available colours and coatings.

FRP Stair Treads and Nosing Options

FRP stair treads are manufactured using similar composite construction techniques to FRP decking systems, ensuring consistent structural strength and performance.

Tread options include:

  • Painted stair nosing for visual step definition
  • Solid stair nosing for high-traffic pedestrian environments

Choose FRP stair nosing for improved visibility and slip resistance in public access infrastructure.

Why Choose Wagners FRP Stairs

Wagners’ FRP stairs provide long-term value for infrastructure owners through their performance advantages:

  • Durable with an expected 100-year design life
  • Inert will not rot, rust, or corrode
  • Resistant to termites and acid sulphate soils
  • Lightweight, making it safer to handle, transport and install
  • Modular by design, so it can be assembled off-site
  • Non-leaching, so it will not release harmful substances into the environment

By prioritising whole-of-life asset performance, FRP stair systems deliver sustainable infrastructure outcomes for councils, engineers and asset managers.
