High-Performance Safety Components for Industrial Ladders
Our FRP (Fiberglass Reinforced Plastic) ladder rungs are engineered for industrial environments where corrosion, electrical exposure, and slip resistance are design priorities. These pultruded fiberglass components provide a non-conductive, corrosion-resistant alternative to steel and aluminum rungs for chemical plants, offshore platforms, and electrical facilities.

Applications & Use Cases
- Chemical Processing Plants: FRP rungs resist exposure to acids, alkalis, and solvents that corrode metal over time
- Offshore Oil & Gas: Suitable for saltwater environments with reduced maintenance compared to painted steel
- Electrical Facilities: Non-conductive material suitable for electrical work environments; dielectric properties should be verified against site-specific requirements
- Food Processing: Meet strict sanitation requirements with non-porous, easy-clean surfaces that resist bacterial growth
- Water Treatment: Withstand constant moisture and treatment chemicals without degradation
- Mining Operations: Provide reliable footing in dusty, abrasive conditions where metal rungs become slippery

Frequently Asked Questions
Q: How long do FRP ladder rungs typically last?
A: Service life depends on load, environment, UV exposure, and resin grade. FRP rungs generally last longer than steel in corrosive environments when correctly specified and installed. Request project-specific guidance for life estimates.
Q: Can FRP ladder rungs be installed on existing ladder frames?
A: Yes. FRP rungs can be installed on new ladders or retrofitted to existing metal ladder frames. Adapter kits are available for common steel ladder configurations.
Q: Are FRP ladder rungs compliant with safety regulations?
A: FRP ladder rungs are manufactured to meet OSHA 1910.23, ANSI A14.3, EN 131, and AS 1657 requirements. Verify final compliance with your local authority and application.
Q: How do I clean and maintain FRP ladder rungs?
A: FRP rungs require minimal maintenance in most environments. Clean with water and mild detergent as needed. Inspect periodically per your facility maintenance program.
Q: Can FRP ladder rungs be cut to custom sizes on-site?
A: Yes, our FRP rungs can be field-modified using standard power tools with abrasive blades or discs. We recommend wearing appropriate PPE during cutting.
Q: How much weight can FRP ladder rungs support?
A: Our standard FRP ladder rungs are rated for a static load of 350kg (770lbs) and dynamic load of 200kg (440lbs). Confirm suitability with your design loads and safety factors.
