FRP (Fiber Reinforced Plastic) manholes are advanced, lightweight, and durable alternatives to traditional concrete, cast iron, or PVC manholes. They are designed to provide superior strength, corrosion resistance, and ease of installation. These manholes are widely used in sewage systems, drainage networks, telecom infrastructure, and industrial applications.
With a robust collection of manhole options ranging from medium duty application to heavy duty application, SRK manholes are 30–50% lighter than concrete or cast iron, making them easy to handle and install. Despite their lightweight nature, they offer high strength due to fiberglass reinforcement. They’re corrosion-resistant, leak-proof, and withstand harsh chemicals, gases, and UV exposure. With a non-conductive, maintenance-free design and a lifespan of 30–50 years, FRP manholes are ideal for sewage, industrial, electrical, and telecom applications.

Myths vs Facts of FRP Manhole Cover
Myths
- More weight means stronger FRP
- More thickness means stronger FRP
- Use of FRP Rods increases the strength
- DMC means less strength
- LDPE/HPDE/PVC & FRP are same
- Rib pattern Provides better strength
Facts
- Strength of FRP is irrelevant to its weight. FRP’s strength depend on its material combination. FRP can provide strength of steel at fraction of steel’s weight
- Similar to weight thickness is also irrelevant to strength of FRP. Thickness can be increased by use auxiliary materials such as calcium, Sand etc. which lowers the strength of FRP
- Individually implanted rods don’t make any significant impact to strength. 40Ton load capacity FRP covers can be made without using rods
- Strength depends on Material combinations. And due to DMC there is Proper Pressure & temperate maintained to provide better Strength & Finish
-
All are different. FRP is strongest and most durable among them
- Rib means lower flow of the material during processing to ribbed parts. And also Ribbed patterns produces microcrack at corners to initiate early breakage.
FRP GRATING
FRP Grating is a strong, durable, and corrosion-resistant alternative to traditional metal grating. It is made by combining glass fiber reinforcement with a polymer matrix (resin). It offers excellent mechanical properties, chemical resistance, and a long lifespan.
Catering to diverse application areas spanning from trench covers to walkways, elevation, wall facing, interiors, and beyond– FRP gratings are corrosion and chemical resistance, lightweight yet strong, non-conductive and fire-resistant, low maintenance and long life, slip-resistant surface

WHY CHOOSE SRK FRP?
GLOBAL REACH
Got Questions? We've Got Answers.
Here’s everything you need to know about FRP, its benefits, and why it's the future of industrial solutions.
Fibre Reinforced Plastic/ Glass Fibre Reinforced Plastic is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually Fibreglass, Carbon, or Aramid, while the polymer is usually an Epoxy, Vinylester or Polyester Thermosetting Plastic.
Composite materials are made up of two or more materials on a macroscopic scale. Polymer matrix composites are plastics (resins) within which there are embedded fibres. The plastic is known as the matrix, and the fibres oriented within it are known as the reinforcement.
The reinforcement tends to be stiffer and stronger than the matrix providing stiffness and strength. Reinforcement is laid in a particular direction, within the matrix, so that the resulting material will have different properties in different directions, i.e., composites have anisotropic properties. This characteristic is exploited to optimize the design and provide high mechanical performance where it is needed.
With extensive demands rising in the industrial landscape, the industry is getting more competitive than ever over the last few decades. It is becoming challenging to present a product that not only caters to our diverse needs and demands but also proves durability and stands firm against all challenges.
FRP, Fibre Reinforced Polymer, has proved to be the best discovery in civil engineering among concrete repair specialists, considering its reliability and efficiency over the long term. FRP reinforcement enhances infrastructure and provides multifaceted industrial solutions.
What are FRP products?
FRP is a superior alternative to traditional materials, composed of a polymer matrix reinforced with fibers made of carbon, aramid, or basalt. This reinforcement enhances the polymer’s properties, making FRP a powerful solution for modern applications. FRP materials effectively address issues like deterioration, daily wear, and the damages sustained by concrete buildings and metals.
Benefits of FRP materials
FRP encompasses all the qualities traditional structural materials lacked. Whether it's corrosion, rust, conductivity, UV degradation, or installation challenges, fiber reinforced polymer is the solution to all civil engineering problems.
With the extensive properties it upholds, there’s a wide array of industries adopting FRP, including aerospace, automotive, marine, and construction industries. FRP not only caters to diverse and exponentially increasing demands but also ensures optimum safety structures.
FRP delivers quality and durability with less cost, and ensures a high strength-to-weight ratio. It has an unmatched performance experience while offering unparalleled strength that steel or iron can't handle.

FRP Ladders
Designed and built to challenge industry norms while ensuring compliance with national and international standards. Catering to extra heavy-duty industrial, heavy-duty industrial, medium-duty commercial, and light-duty household applications– while maintaining strict safety standards.
FRP ladders prove superior to traditional materials like metal, steel, wood, and others. They excel in non-conductivity, stability, and safety features like guard rails. This comprehensive range of products is tailored to meet specific industrial needs. SRK – A SDI Product, is dedicated to providing the best solutions to industrial challenges with their range of fiberglass ladders, setting new standards in durability, safety, and performance.
The civil engineering industrial diaspora is rapidly growing at a faster pace than ever before. The traditional practices of advanced composite components, however, fail to meet the exponential and structural demand of the sector. These traditional materials lead to high material and manufacturing costs while succumbing to corrosion, degradation, and limited durability.
The need of the hour calls for the adoption of new lightweight structural concepts globally, utilizing either all-FRP systems or new FRP/concrete composite systems. FRP strengthens the industry by reinforcing high strength-to-weight and stiffness-to-weight ratios, corrosion resistance, lightweight properties, and potentially greater durability than its conventional counterparts.
FRP won’t rust or corrode in wastewater and water treatment facilities. FRP endures severe weather challenges, offers durability and cost-effectiveness, and has proven to be the best component for pedestrian bridges, cooling towers, and military applications. Its anti-slip properties and strength make it ideal for the oil and gas industry, while its non-conductivity is advantageous in thermal and electric plants. It doesn’t stop here—the usage of FRP is never-ending, and industries eager for a better tomorrow and committed to providing the best are switching to Fibre Reinforced Polymer solutions.
