FRP molded grating is manufactured by combining fiberglass reinforcement with a resin matrix to create a rigid structural panel.
The fiberglass provides mechanical reinforcement, while the resin provides resistance to moisture and many corrosive environments.
Unlike ordinary steel grating, FRP does not experience conventional rust corrosion. This makes it particularly useful inside cooling towers, where components can be continuously exposed to water, humidity, chemical treatment, and wet operating conditions.
The molded grid structure also provides a large open area for water and air movement.
A typical cooling tower filler support arrangement works as follows:
Structural beams or support members are installed inside the cooling tower.
FRP molded grating panels are positioned on the support structure.
The grating is mechanically secured to prevent movement.
Cooling tower fill packs are installed above the support grid.
Hot circulating water flows downward through the fill.
Air moves through the open fill and support structure.
The FRP support grid carries the applicable static and operational loads.
The exact support arrangement depends on the cooling tower design, fill type, fill height, water loading, panel span, and structural requirements.
Cooling towers are continuously exposed to water and humid air. Water treatment chemicals can also create corrosive conditions.
FRP molded grating provides excellent resistance to moisture and many common industrial corrosive environments, making it a suitable material for cooling tower fill support applications.
FRP provides a favorable combination of structural strength and relatively low weight.
This makes panels easier to transport and handle during cooling tower construction or replacement work.
The open-grid configuration provides large passages for water and air.
This is important because the filler support should provide structural strength without creating unnecessary obstruction beneath the cooling tower fill.
Water can pass through the openings in the grating instead of accumulating on the support surface.
Good drainage helps reduce standing water and supports proper operation of the cooling tower internal system.
When the correct resin and structural specification are selected for the operating environment, FRP grating can provide long-term service with relatively low maintenance.
Unlike painted steel support structures, FRP does not require routine anti-rust painting. Regular inspection and cleaning are still recommended.
FRP fill support grating can be installed beneath film fill or splash fill in counterflow cooling towers.
The support structure must be selected according to the fill height, water loading, span, and required structural capacity.
Industrial cooling towers may operate under demanding water and environmental conditions. FRP provides corrosion resistance and low-maintenance performance for internal support structures.
FRP filler support can be used in suitable commercial HVAC cooling tower applications where the structural and dimensional requirements are satisfied.
Existing steel or deteriorated support grids can be replaced with FRP molded grating where the new system is appropriately engineered for the existing tower.
During tower refurbishment, damaged fill support structures can be replaced at the same time as cooling tower fill, drift eliminators, spray nozzles, or other internal components.
FRP molded grating can be used as a support structure for different types of cooling tower packing, provided the structural configuration is correctly designed.
Typical applications include:
PVC film fill
PP film fill
PVC cooling tower packing
PP cooling tower packing
Splash fill
Grid fill
Hybrid fill systems
The support structure should be matched to the dimensions, weight, water loading, and installation method of the selected fill.
Actual specifications should be determined according to the tower design and required structural loading.

Steel can provide high structural strength, but cooling tower environments can accelerate corrosion, particularly when protective coatings become damaged.
FRP offers several advantages for wet internal tower structures:
No conventional steel rust
Lower weight
Excellent moisture resistance
Good chemical resistance
Open drainage structure
Low maintenance requirements
Non-conductive characteristics
Easy handling and fabrication
However, material selection should always be based on the specific structural, thermal, chemical, fire, and regulatory requirements of the project.

When selecting cooling tower fill support grating, consider:
Fill type
Fill height
Fill module dimensions
Fill weight
Water loading
Maximum operating water volume
Support beam spacing
Unsupported grating span
Panel thickness
Mesh opening
Operating temperature
Chemical exposure
Tower dimensions
Installation method
The grating should be supported at appropriate intervals so that the panel does not experience excessive deflection under operating loads.
For larger cooling towers, the support system may consist of FRP grating installed over engineered FRP, steel, concrete, or other structural members.
Cooling towers vary significantly in size and internal configuration. Custom FRP filler support panels can therefore be manufactured according to project requirements.
Customization can include:
Panel length
Panel width
Panel thickness
Grid opening
Resin type
Color
Load capacity
Cutouts
Panel shape
Support arrangement
Installation configuration
For replacement projects, customers can provide the existing grating dimensions and photographs. For new projects, engineering drawings and tower dimensions can be used to develop the appropriate support configuration.
The resin system is an important factor in determining the chemical and environmental resistance of FRP grating.
Depending on the application, available resin systems may include:
Suitable for many general industrial environments and standard cooling tower applications.
Can provide enhanced resistance compared with general-purpose polyester in selected applications.
Often considered for more aggressive chemical environments where higher chemical resistance is required.
The appropriate resin should be selected according to the cooling-water chemistry, treatment chemicals, temperature, and surrounding environment.
For replacement projects, inspect the existing beams and support members before installing new grating.
Measure the required panel length, width, support spacing, and openings.
Place the FRP panels onto the designed support members with adequate bearing.
Use appropriate mechanical clips, clamps, bolts, or other approved fastening systems to prevent panel movement.
After confirming that the support grid is stable and properly aligned, install the cooling tower fill modules according to the fill manufacturer's installation instructions.
Check panel stability, support conditions, fill alignment, water distribution, and airflow passages before commissioning.
FRP fill support is relatively low maintenance, but periodic inspection is recommended.
Maintenance should include:
Checking for cracks or impact damage
Inspecting support members
Checking fastening hardware
Removing accumulated debris
Inspecting for chemical deterioration
Checking excessive deflection
Inspecting areas around fill supports
Cleaning deposits where necessary
The cooling tower's water-treatment program should also be maintained to reduce scale, biological growth, and chemical damage to internal components.
Inspect the support grid if you observe:
Cracked panels
Broken grid sections
Excessive deflection
Loose panels
Damaged fasteners
Chemical degradation
Structural deterioration
Fill modules moving from their original position
Uneven or unstable fill support
Corrosion or deterioration of existing steel support members
Damaged support structures should be evaluated before continued operation because failure of the support system can affect the cooling tower fill and other internal components.
