Pharmaceutical facilities place different demands on structural and support materials depending on the area and process. Production spaces, cleanrooms, service corridors, utility areas, and equipment platforms may be exposed to cleaning chemicals, moisture, temperature changes, mechanical loads, or other operating constraints. Material selection therefore needs to consider the conditions of each application rather than treating the facility as a single environment.

Fiberglass reinforced plastic (FRP) can be considered for selected pharmaceutical facility applications because it provides a non-metallic construction option and can offer corrosion resistance in wet or chemically exposed environments. Its suitability is not automatic, however. The resin system, surface finish, structural configuration, fire-performance requirements, and operating conditions all affect the selection.

Environmental Conditions in Pharmaceutical Facilities

Different areas within a pharmaceutical facility can present very different material requirements:

  • Cleanrooms and controlled environments: material surfaces may need to support effective cleaning and be compatible with the facility's contamination-control practices and cleaning agents.
  • Washdown and process areas: repeated exposure to water, moisture, and chemical cleaning agents can increase corrosion concerns for conventional metal components.
  • Solvent-exposed areas: some processes use organic solvents that can affect particular resin systems, making chemical compatibility an important part of material selection.
  • Areas with non-metallic material requirements: some applications may place additional limits on the use of conventional metallic components because of process, equipment, magnetic, or contamination considerations.
  • Fire-performance requirements: enclosed spaces and areas associated with flammable materials may have specific fire-performance requirements that influence the choice of FRP formulation and product configuration.

These conditions should be considered together. A resin system that performs well against a particular chemical exposure may not be the preferred option for a location with different fire, surface, loading, or operational requirements.

Typical FRP Applications in Pharmaceutical Facilities

Mezzanine Walkways and Platforms

Mezzanine levels may be used for equipment access, piping, cable runs, and utility services. In areas exposed to washdown, humidity, or cleaning chemicals, FRP grating can be considered as an alternative to conventional metal walkways. Molded open mesh grating provides a lightweight structural surface with open areas for drainage, ventilation, and light transmission. Whether an open mesh surface is appropriate for a particular controlled environment depends on the area's cleaning, hygiene, and operational requirements. See molded open mesh grating for product details.

Cable Tray and Utility Supports

Pharmaceutical facilities require organized support for electrical, instrumentation, and utility services. FRP cable tray provides a non-metallic support option for applications where corrosion resistance or non-metallic construction is preferred. It may be considered in service corridors, laboratory support areas, and other locations exposed to moisture or cleaning chemicals. Selection should account for the cable arrangement, support spacing, loading, environment, and the complete installation system. Visit fiberglass cable tray for more information.

Platforms Around Tanks and Processing Equipment

Access platforms around mixing tanks, reactors, and other processing equipment can be exposed to moisture, washdown, and chemical cleaning. FRP platforms may be suitable for these applications when the selected resin system and structural configuration are compatible with the service environment. Anti-slip surfaces can also be considered where wet operating conditions create a slip risk.

Resin Selection and Chemical Compatibility

For pharmaceutical facility applications, resin selection is one of the most important parts of chemical compatibility. Cleaning agents and solvents can vary in chemical concentration, temperature, contact time, and frequency of exposure, so a resin that is suitable for one cleaning regime may not be suitable for another.

In broad terms, isophthalic polyester systems are generally considered for moisture exposure and less aggressive chemical environments, while vinyl ester systems may offer greater resistance for some more demanding exposures. These are material-selection guidelines rather than universal rules.

Before specifying an FRP product, identify the chemicals used in cleaning and processing, together with their concentrations, temperatures, contact times, and exposure frequency. Chemical-resistance information should then be matched to the specific resin system and product configuration being considered.

Fire Performance Considerations

Some pharmaceutical facility applications have defined fire-performance requirements, particularly in enclosed spaces or areas associated with flammable materials. FRP product families may be manufactured using flame-retardant resin systems, but fire performance is not determined by the resin description alone.

The applicable performance depends on factors such as the resin formulation, product geometry, construction, and the test requirements specified for the project. A fire-performance classification should therefore be treated as configuration-specific and supported by relevant test evidence before it is used in a project specification.

For this reason, terms such as “fire-rated” or “Class A” should not be applied broadly to FRP products without confirming that the specific configuration has been tested to the required method and that the supporting result applies to the product being specified.

Other Engineering Boundaries

Pharmaceutical applications can combine chemical cleaning, moisture, temperature variation, and mechanical loading. Laboratory results from exposure to a single chemical may not represent performance under a cleaning program that uses several agents in rotation. Steam or high-temperature cleaning can also change the severity of the service environment.

Surface condition is another consideration, especially where cleaning and contamination control are important. The selected finish should be evaluated together with the intended use, cleaning method, potential wear, and the condition of the installed surface over time.

Selection and Cost Factors

FRP selection should be made at the system level rather than from resin type alone. Important variables include the chemical exposure, product geometry, mechanical load, support spacing, surface finish, hardware, fabrication requirements, installation access, and maintenance conditions.

These variables can also affect total project cost. A lower material cost does not necessarily produce a lower installed cost if the project requires additional fabrication, specialized hardware, different support arrangements, or more demanding installation conditions. For this reason, cost comparisons are most useful when they consider the complete application rather than material price alone.

Summary

FRP can be considered for a range of pharmaceutical facility applications, including walkways, platforms, cable supports, and other non-metallic structural or service-support components. The main selection questions are not simply whether FRP is “suitable” for pharmaceutical facilities, but whether the chosen resin system, surface finish, structural configuration, and fire-performance characteristics match the requirements of the specific area.

A practical specification therefore starts with the facility's cleaning regime, chemical exposure, loading, surface requirements, fire-performance criteria, and installation conditions. Matching those factors to the available FRP configuration provides a more reliable basis for material selection than applying a general suitability statement to the entire facility.
