GRP Pipes

Distinct Types of Composite Materials Used by GRP Pipes Manufacturers India


Composite materials are composed of two or multiple components that are combined in a way that lets the materials to stay identifiable and unique. GRP Pipes Manufacturers India are going to discuss about different types of composite materials that they apply for manufacturing products for several clients.

The components used with the composite materials like FRP, GRP add strength to the material. Composites are not similar to alloys like bronze or brass. Alloys are developed in a way that it is impossible to differentiate between them. Some commonly used composite materials include concrete, mud bricks, fiberglass, and natural composites like wood and rock.

Manufacturers classify the composite materials on the basis of the type of reinforcement they use. The manufacturers use matrix as a binding material to hold it together. They use reinforcement to strengthen the composite. You can take the mud brick as an instance. In the mud brick, the matrix is the mud and the reinforcement is the straw. General composite types include random fiber, continuous fiber, shirt fiber reinforcement, or long fiber reinforcement, particulate reinforcement, filler reinforcement and flake reinforcement.

Mud building bricks

These are the instance of a composite material that was invented by ancient human. Mud building brick is a brick formed with mud. It is sturdy and resistant to compression, but it has bit flexibility and it cannot resist bent. Ancient humans were able to form these composite bricks by combining both straw and mud and the bricks could remain flexible while supporting weight and resisting compression.

Concrete and reinforced concrete

Concrete is a composite material that is made with sand, cement, stones, and water. When you combine these ingredients, a chemical reaction occurs that makes concrete stronger than any one of its ingredients. Concrete is specifically used by building and construction sector to build roads and structures. When experts add reinforced steel rods to the concrete, they make another composite with greater strength and flexibility. This concrete is known as reinforced concrete.

Natural composites

Natural composites like wood are easily available in nature. Wood is an ideal composite instance as it has cellulose fibers that are held together by lignin substance. These fibers can be found in cotton and thread. However, it is the power of bonding of lignin in wood that makes the material tougher.


Fiberglass is derived from tiny glass shards that are held together by resin and other components. Fiberglass is widely used by automobile sector for making body kits. Do you know? The body of the car is made of distinct numbers of fiberglass layers, such as gel coat layer, matting, tissue layer, and cloth. Fiberglass based products are waterproof, lightweight and high strength.

FRP and GRP are the fiberglass composites.

FRP Pipes, GRP Pipes

What Happens When You Overlook FRP Pipes Made in India?

Fiberglass reinforced plastic material is sturdy and the products made of FRP materials required minimum attention. Manufacturers of FRP pipes in India always suggest their clients to never overlook FRP products even if they needed minimum care and maintenance. Composite FRP products maybe strong and durable, but their life depends on the way you care and sustain them. These are best feasible products that can replace old traditional pipes. Engineers leveraging FRP pipes should have proper understanding of its nature and properties.


There are many reasons behind the increasing demand of FRP range of products, we will explain them now.

FRP pipes are inherently corrosion resistant because of the inert nature of materials used for fabricating them as compared to general steel and cast iron. FRP materials have potential to resist corrosion from wide range of chemicals and fluids. Moreover, engineers can rely on an apt interior-liner or barrier material and make use of resin matrices so that pipe can accommodate internal and external corrosive environments that are not alike to each other.

Their light weight built is also a major benefit. General FRP pipe’s weight is about 25% of the comparable steel pipe and 10% that of comparable concrete pipe. This feature makes the product very cost effective as the cost of shipping, installation and handling is much lower.

These products are used by different industries, for example, oil fields mostly rely on light-weight FRP pipes to lower the energy needs related to drilling, pumping and offshore-platform operations. The fatigue endurance and the strength-to-weight ratio of fiberglass reinforced pipe are major attributes connected with replacement costs and the potential to intend high-performing, lightweight pipe systems.

A general FRP pipe doesn’t conduct electricity, and has better electrical properties as compared to steel pipes. FRP pipe can be fabricated as per the custom specifications. It means a customer can request for FRP pipe and give his own design to the manufacturer and avail the exact product at reasonable rates. Manufacturers design and intend complex shapes of FRP products and clients can avail these all products from them easily. Many of these shapes are not easy to fabricate and way too expensive when it comes to metallic materials.
