What sets a fiberglass handrail apart is the general absence of metal in the safety path. In a substation switchyard or an electrolytic cell house, a steel handrail can introduce a conductive loop that may energise during a fault or induction event. An all‑FRP system typically removes that risk. The round top rail commonly sits at the standard 1.1 m (42 inch) height with an intermediate mid‑rail and a 100 mm toe board channel, meeting OSHA walking‑working surface requirements without any conductive path to ground.
Because the posts and rails are pultruded from the same resin system used across the WayTong FRP access components range, corrosion resistance is generally uniform from the base plate to the top cap. Corrosion resistance is commonly verified per ASTM D543. In coastal processing terminals where salt mist attacks galvanised posts within two years, the FRP handrail often passes close‑out inspection five years later without repainting or replacement. And because the system is delivered as a pre‑cut kit, a two‑person crew can typically complete a 30‑metre straight run in a single shift with basic hand tools.
The modular connection system absorbs tolerance stack‑up across a long run. Posts can be shimmed at the base, and rails slide into connectors with a few millimetres of axial play before locking. That removes the exact on‑site cutting and welding that steel systems commonly force. It also means a retrofit into an existing platform or walkway structure commonly uses the same anchor bolt footprint, so there is no concrete drilling work. Top rail is typically round tube Ø 42 mm, with mid‑rail Ø 33 mm. Posts are square tube 50 × 50 mm, height 1.2 m, with pre‑drilled base plates. Maximum post spacing is 1.5 m, adjustable to fit existing anchor patterns. Fittings use 316 stainless steel or FRP angle brackets with 316 stainless steel fasteners. Resin systems include isophthalic polyester as standard, with vinyl ester available for aggressive chemical exposure. Fire performance generally achieves a flame spread index ≤ 25 when tested per ASTM E‑84. The consistent pultruded construction of FRP composite materials provides uniform corrosion resistance throughout every component in the handrail assembly.

Proven in Field
"We specified FRP handrails for the entire cell house rooftop after a steel rail became live during a ground‑fault test. The kit arrived labelled by section, and the crew assembled 80 metres in two days without a single hot work permit. The rails have been in place for four years with no measurable degradation."
