Improves the anti-slip conditions on flooring surfaces
Ladder Rung Covers
Our Ladder Rung Covers are pultruded Fibreglass Reinforced Polymer (FRP) profiles engineered to improve ladder safety by providing enhanced grip and footing confidence in demanding environments. Manufactured as a 50 mm wide, 14 mm deep profile with a 3 mm wall thickness and supplied in standard 3000 mm lengths, they provide a durable anti-slip solution for both new ladder installations and the upgrade of existing ladder systems.
Combining excellent corrosion resistance, wear performance and durability, Ladder Rung Covers provide a low-maintenance solution for improving climbing safety in industrial, commercial and infrastructure environments. Commonly specified for fixed ladders, access ladders and maintenance platforms, they are designed for applications where reliable slip resistance, secure footing and long-term performance are key considerations.
Pultruded Grating is designed for applications where structural efficiency, long spans and long-term durability are key considerations.

Resin Systems
Our anti-slip ladder rung profiles use a pultrusion process, ensuring consistent profile geometry, uniform resin distribution, and durable bonded grit surfaces.
Developed through more than a decade of refinement across resin chemistry, pigment stability, UV protection and manufacturing consistency, our resin platforms are engineered for long-term industrial performance in demanding environments.
- ISO-PLEX (Isophthalic Polyester Resin)
Developed for dependable all-round industrial performance, ISO-PLEX combines balanced resin chemistry, UV resistance, and moisture protection into a versatile FRP system designed for reliable structural performance and long-term visual consistency across outdoor and industrial applications.
Our Surface System
Ladder Rung Covers are manufactured using a pultrusion process, ensuring consistent profile geometry, uniform resin distribution and long-term dimensional stability. Designed to improve footing on ladder rungs and provide a durable anti-slip solution in wet, dirty and demanding environments, each profile is supplied with our bonded CARBIXTM anti-slip surface.
Developed through years of real-world industrial application and refinement, our surface systems are designed to balance slip resistance, wear life and long-term durability.
- CARBIXTM Medium Grit
Applied directly to the pultruded substrate, CARBIXTM Medium Grit is our standard anti-slip surface system for Ladder Rung Covers. Developed to maximise grit retention, wear life and long-term traction performance in demanding industrial environments. Typical grit sizes are approximately 600 μm (similar to P40 abrasive media), providing dependable slip resistance and enhanced footing confidence when ascending or descending ladders in both indoor and outdoor applications.
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.
