Fibreglass Stair Nosing

Our FRP (Fibre Reinforced Polymer) anti-slip stair nosing, also known as fibreglass stair nosing, is durable and low-maintenance. It is suitable for new stairs or to upgrade existing stair edges in commercial and industrial applications. It provides visibility in low-light conditions and distinguishes uneven rises between treads. It protects your stair edges from further wear and prevents slip accidents caused by worn step edges and slippery surface conditions.

Resin Types

Isophthalic polyester (ISO) – general purpose grade resin suitable for minimal contact with harsh chemicals

Grit Surfaces

We offer various anti-slip grit finishes designed to match your environment:
Fine Grit (125-210 µm | Approximately P120–P80 to FEPA Classification): Barefoot-friendly and comfortable underfoot, perfect for public walkways, aquatic areas, schools, and anywhere people may be in lighter footwear or barefoot.
Medium Grit (600 µm | Approximately P40 to FEPA Classification): The trusted choice for general, commercial, and industrial use, providing reliable slip resistance in workshops, plants, and high-traffic areas.
With both options, you get the right balance of safety, comfort, and performance.

Water Absorption Testing

Testing was carried out by SGS. in accordance with ASTM D570-22 on our moulded FRP products manufactured using ISO and VE resin systems.

Test Conditions:

Dried at 50 ± 2 °C for 24 h
Soaked in water at:

  • 23 °C for 24 h
  • 100 °C for 2 h
  • 50 °C for 48 h

Measured Water Absorption (%):

Condition

             Sample A

                              Sample B

                          Assessment

23 °C / 24 h

             0.17 %

                              0.09 %

                          Excellent resistance – negligible absorption

100 °C / 2 h

             0.49 %

                              0.47 %

                          High stability – minimal uptake under heat

50 °C / 48 h

             0.52 %

                              0.71 %

                          Strong retention – remains below 1 % threshold

Interpretation:
Results demonstrate consistently low water absorption across all temperature and duration tests, confirming a dense, well-cured laminate structure.
Moisture uptake remained below 1 %, supporting dimensional accuracy, mechanical reliability, and long-term surface integrity.
Performance levels are within the expected range for high-grade structural FRP composites and trend toward the lower end of typical absorption values, indicating slightly improved resistance compared with standard industry benchmarks.

 

Low-VOC Pigment

Our colour system utilises a polyester-based pigment dispersion that chemically bonds within the FRP matrix, rather than just coating it. This 100 % solids, low-VOC formulation delivers cleaner processing, longer-lasting colour, and superior UV stability compared to solvent-borne alternatives. It’s a smarter, more sustainable way to colour FRP.

Electrical Insulation Testing

Testing was carried out by SGS in accordance with ASTM D495-22 and ASTM D149-20 on our FRP moulded products manufactured using ISO and VE resin systems.

Test Conditions:

  • Dry Arc Resistance (ASTM D495-22)
     • Arcing voltage: 12.5 kV • Electrode gap: 6.35 mm • Environment: 23 °C / 50 % RH
  • Dielectric Breakdown (ASTM D149-20)
     • Transformer oil medium • Voltage rise: 3000 V/s • Frequency: 50 Hz

Measured Electrical Performance:

Property

      Sample A (ISO resin)

                       Sample B (VE resin)

              Assessment

Arc Resistance Time (s)

      182.5 s

                       146.2 s

              Excellent surface insulation – high resistance to tracking

Dielectric Strength (kV/mm)

      15.6 kV/mm

                       12.5 kV/mm

              Strong electrical barrier – stable under high voltage

Interpretation:

Results confirm both resin systems deliver high-grade electrical insulation consistent with the requirements of ASTM D495 and D149.
The ISO-resin laminate achieved the highest overall performance, showing extended arc-resistance duration and greater dielectric strength, indicating a dense, well-cross-linked matrix with minimal conductive pathways.
The VE-resin laminate also exhibited strong insulating capability, remaining well within the range expected for premium structural FRP composites.

Electrical performance across both systems supports their suitability for installations requiring high-voltage isolation, reduced surface tracking, and long-term reliability in wet or industrial environments.
