FRP Application Guide

FRP cooling tower profiles for wet and chlorinated service

Pultruded FRP cooling tower profiles for wet, chlorinated and high-humidity structures: beams, tubes, louvers, handrails and access members.

Short answer

Cooling towers attack galvanized steel through constant humidity, chlorides, biocides, and wet-dry cycling. F1 Composite supplies pultruded FRP beams, tubes, angles, louvers, and grating supports that keep structural stiffness while removing corrosion-driven maintenance.

Best fit: industrial cooling towers, power plant cooling systems, HVAC towers, chemical plants, and replacement programs where steel members require repeated recoating.

Recommended profiles

FRP I-beams and channels for primary support members

FRP square tubes for frames, posts, and bracing

FRP angles for edge supports and louver framing

Custom thin-wall pultrusions for drift eliminators and louvers

Resin and standards

Resin recommendation

Vinyl ester is recommended for chlorinated water, high humidity, and aggressive cooling tower chemistry. Isophthalic polyester can be used for mild HVAC towers with controlled water treatment.

Common standards
