Application· FRP cooling tower profiles

FRP cooling tower profiles for wet and chlorinated service

Start with the tower task: replace existing members, supply profiles for a new-tower OEM, or provide maintenance-access components. F1 Composite supplies pultruded beams, tubes and angles to an agreed scope; member selection depends on loads, connections and the actual water-treatment exposure.

Where it fits and what we supply

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

Identify raw lengths, cut or drilled members and any agreed grating or handrail components on the BOM. Confirm custom louver sections separately. Tower thermal performance, fan and fill design, complete structural verification and installation responsibility must be allocated in the project scope.

This page describes how the products are used; design and installation are included only where the quotation says so.

Recommended profiles and resin

  1. 01I-beams and channels for primary support members
  2. 02Square tubes for frames, posts, and bracing
  3. 03Angles for edge supports and louver framing
  4. 04Custom louver or casing-support sections subject to drawing and tooling review

Resin

Compare the offered polyester or vinyl ester formulation against operating temperature, pH, chemical concentrations, biocide dosing and cleaning cycles. Confirm the relevant exposure evidence and surface / cut-edge treatment; a resin name alone does not establish service life.

Design and specification checks

  1. Check 1

    Water chemistry and temperature

    Provide chloride concentration, pH, biocide program, operating temperature, and cleaning chemicals. Resin selection must be checked against the combined exposure rather than against humidity alone.

  2. Check 2

    Buckling and sustained load

    Columns, diagonal braces, and fan-deck members require global and local buckling checks. Permanent equipment and casing loads also require the applicable long-duration design factors.

  3. Check 3

    Connections in saturated service

    Connection plates, bolt bearing, drainage details, and cut-edge sealing need to be coordinated so trapped water and repeated wet-dry cycling do not create avoidable local damage.

Three cooling-tower procurement tasks, three drawing packages

Existing-member replacement starts with a site survey, marked framing drawings, member IDs, hole patterns and the condition of retained connections. Include the governing loads and water-treatment history. The project engineer checks the replacement load path, stiffness, buckling and local bearing; matching a steel member's outside dimensions does not establish an equivalent FRP member. Agree access, lifting limits and the outage sequence before releasing fabrication.

New-tower OEM supply starts with the OEM's controlled profile drawings, material specification, quantities and interface tolerances. Identify fan, fill, casing and bracing reactions, then agree first-article checks, production inspection and revision control. If the specification cites CTI or other standards, identify the edition and required evidence for the offered product; a reference in a specification is not certification of the tower or its thermal performance.

Maintenance-access work starts with the walkway or stair layout, grating span direction, support spacing, openings and handrail reactions. Define whether the order includes only profiles, cut components or an agreed access package. Confirm who designs the retained structure, bases and anchors, and list the drawings, BOM, inspection records and any project-specific tests required for acceptance. Their availability and scope are confirmed before order release.
