What FRP Products Are Suitable for Smart City Infrastructure in India?
The smart cities initiative in India needs infrastructure that would be capable of withstanding the corrosive effects, wear and tear, exposure to moisture and harsh environments, etc. FRP products have become quite handy in these kinds of applications as they are light in weight, resistant to corrosion, and easy to maintain.
There are several FRP products available that can be used for smart city infrastructures in India.
1. FRP Gratings
FRP gratings are ideal for use on walkways, drainages, platforms, utility spaces, treatment plants, and maintenance areas.
As opposed to metallic gratings, which will rust, FRP will not rust and thus can be used in environments where there is exposure to rainwater, effluents, chemicals, and even humidity.
Typical uses include:
- Drain covers
- Walkways/Platforms
- Treatment plants
- Utility spaces
- Maintenance platforms
FRP grating can also be available in various loading capacities based on the use.
2. FRP Ladders
Electrical sub-stations, water plants, pumping plants, utility buildings, and various types of installations in smart cities are places where access for maintenance is necessary.
FRP ladders can be employed at these locations as they have the following advantages:
- Corrosion resistance
- Lightweight
- Non-conductive to electricity
- Low maintenance
- Outdoor suitable
Aluminium/steel ladders may not be appropriate in some cases due to the above reasons.
3. FRP Cable Trays
Modern cities rely extensively on electrical, communication, CCTV, networking and various other utility systems. Such cables need organized and secure routing.
FRP cable trays can be employed for the routing of cables in:
- Electrical systems
- Utility tunnels
- Data/communication systems
- Water treatment plants
- Industrial services
- Infrastructure buildings
The chemical resistance of these cable trays helps them perform effectively in wet and corrosive environments.
4. FRP Benches and Municipal Seating
Development of smart cities does not just involve utilities. Municipal spaces such as parks, pathways, gardens, bus shelters, and recreational spaces need sturdy street furniture.
Use of FRP bench patti as a part of FRP benches may be considered in municipal seating applications due to their resistance to outdoor conditions while being relatively easy to maintain.
They may be used for:
- Public parks
- Gardens
- Pathways
- Bus shelters
- Community centers
- Municipal projects
5. FRP Manhole Covers and Access Covers
Utility infrastructure requires regular access to underground systems. Depending on the design and required load rating, FRP access covers can be considered for selected applications.
Potential applications include:
- Electrical utility areas
- Drainage systems
- Water infrastructure
- Telecommunications infrastructure
- Service corridors
The appropriate FRP cover should always be selected according to load requirements, dimensions, installation conditions, and applicable project specifications.
6. FRP Structural Sections
Lightweight supporting and access systems can be created using FRP structural sections such as channels, angles, beams, and ladders.
Their use could be appropriate when engineers need:
- Reduced structural weight
- Corrosion protection
- Decreased maintenance requirements
- Extended structural life in severe conditions
Potential applications include equipment supports, platforms, handrails, walkways, and utility structures.
7. FRP Handrails and Safety Systems
Handrail installation is commonly needed on public and utility infrastructure at raised platforms, ramps, walkways, treatment facilities, and maintenance facilities.
FRP handrails can be a corrosion resistant solution in places where conventional handrail systems are subject to frequent maintenance needs.
They are applicable to:
- Water treatment plants
- Sewage treatment plants
- Utility facilities
- Pedestrian facilities
- Maintenance platforms
8. FRP Fencing and Barriers
There are some smart city amenities that need controlled access in proximity to electrical, utility, and water facilities among others.
FRP fencing and barriers could come in handy in instances where corrosion protection is paramount.
Not only does FRP have the benefit of being light, but its very properties make it ideal for use in harsh environments.
Corrosion resistance: Fiberglass reinforced plastic does not rust like traditional steel and is suitable for humid and chemical environments.
Light weight: It is easier to ship, handle, and install FRP products than metal counterparts.
Minimal maintenance: The lack of need for maintenance due to corrosion might be an advantage for extensive municipal infrastructures.
Non-conductivity: Some types of FRP products might be useful in electrical systems that require non-conducting material.
Weatherability: Fiberglass reinforced plastic can be produced to withstand the conditions of being used outdoors.
Durability: Longevity of the product depends on various factors including resin selection, reinforcement, design, loading, etc.
Where Can FRP Be Used in Smart Cities?
| Smart City Area | Suitable FRP Products |
|---|---|
| Parks & public spaces | FRP bench patti, benches |
| Drainage infrastructure | FRP gratings, access covers |
| Electrical infrastructure | FRP ladders, cable trays, gratings |
| Water treatment | FRP gratings, ladders, handrails |
| Sewage treatment | FRP gratings, walkways, ladders |
| Utility corridors | FRP cable trays, structural sections |
| Pedestrian infrastructure | FRP gratings, handrails |
| Maintenance facilities | FRP ladders, platforms, gratings |
| Industrial municipal facilities | FRP structural sections, gratings, ladders |
FRP products can support several areas of smart city infrastructure.
How to Select the Right FRP Product
Selection of an FRP material for the smart city project must not be solely based on its price. Rather, it is important to consider what the application demands in terms of the material required for such a project.
Some of the key factors include:
- Load rating
- Dimensions/span
- Exposure to chemicals
- Temperature
- UV exposure/outdoor installation
- Resin required
- Surface treatment
- Method of installation
- Service conditions
- Project specifications
For instance, an FRP grating that is used in a pedestrian walkway is expected to have different specifications from that which is used over industrial machinery.
Conclusion
There are many types of FRP products that can prove to be valuable to smart cities in India if corrosion, lightweight, non-conductivity, and low maintenance are required.
Examples include FRP gratings, ladders, cable tray, bench patti, handrail, structural shapes, and access covers, which may be used in various utility, electrical, water, wastewater, and public places.
It is important to choose FRP products depending on the load, environment, chemical attack, size, and requirements of the project rather than using all kinds of FRP products for every purpose.
This will help create infrastructure that is easier to maintain in Indian conditions.
