Case at a glance: Along a public coastal walkway, the original steel handrail had been in place for years, but constant exposure to salt-laden air and sea spray had caused visible rust, especially near joints and base plates. HotFRP supplied a fiberglass handrail system to take its place. The new railing provides a stable grab surface for pedestrians and does not depend on protective coatings to withstand the coastal environment.

Project Background

The walkway runs parallel to the shoreline and receives heavy pedestrian traffic throughout the year. The existing carbon steel railing had been galvanized and painted, but the coating system struggled to hold up against the combination of salt, moisture, and UV exposure. Regular touch-up painting was needed, and some sections had developed sharp rust flakes that made the railing unpleasant to touch.

The owner wanted a railing that would keep its appearance and structural function without a recurring painting schedule. Since the walkway was already in active use, the installation also needed to be straightforward and not require heavy equipment or long closures.

Material Selection

HotFRP recommended a fiberglass reinforced polymer (FRP) handrail system. FRP is commonly used in marine and coastal settings because the material does not rust, and the resin matrix resists the effects of salt spray and high humidity. The railing components are lightweight compared with steel, which made manual handling easier along the walkway path.

The system was supplied with a standard smooth finish in a neutral color, selected to blend with the surrounding waterfront environment. The handrail profile and mounting brackets were matched to the existing post spacing, so the original foundation points could be reused without major modification.

Installation Notes

Installation was completed in sections, allowing the walkway to remain partially open to pedestrians during the work. The lightweight nature of the FRP components allowed the crew to carry and position rails without cranes or lifts. Mechanical fasteners were used at all connection points, with no field drilling required for the main railing sections.

Because the original base plates were still in sound condition, the new posts were anchored directly to the existing concrete curb using the same bolt patterns. A small number of end caps and corner pieces were trimmed to fit, and any cut edges were sealed with a resin touch-up kit before final assembly. This step helps prevent moisture from reaching the glass fiber reinforcement at cut locations.

Outcome and Observations

Since installation, the railing has required only routine cleaning with water to remove salt residue. There has been no need for repainting, and the surface has remained smooth and comfortable to the touch. Pedestrians and maintenance staff have noted that the railing stays cooler to the touch under direct sunlight compared with the dark painted steel it replaced, which was an unexpected benefit for a public walkway in a warm coastal area.

This case demonstrates how switching to an FRP handrail system can address a persistent corrosion problem in a marine setting without changing the overall structure of the walkway. Material choice and simple mechanical connections made the upgrade practical, even with limited site access and an active public space.
