Operating seven manufacturing facilities, 900,000 square feet of manufacturing space and more than 800 employees, EPP Composites Pvt. Ltd. (Rajkot, India) produces more than 60 products for industrial and utility infrastructure including pipes, industrial tanks, gratings, pultruded profiles and sheet molding compound (SMC) products.
The company was founded in 1986 by Siddharth Shah, current chairman and mechanical engineer and rubber plastic technologist by training, and Jayraj Shah, managing director. The original goal was to establish a company within the rapidly growing composites industry, with a focus on high-quality products and customer service.
EPP Composites operates seven total manufacturing facilities. In the pictured facility, pipes and underground petroleum storage tanks are manufactured via continuous filament winding (CFW).
Since then, the company “has been guided by a vision that encompasses global leadership, technological excellence, industry diversification and a steadfast commitment to creating tangible value for our customers. This vision has been instrumental in shaping EPP’s identity as a dynamic and forward-looking player in the composites industry,” explains Devvrat Shah, director.
EPP Composites is a two-time honoree for CW Top Shops, in 2021 and most recently in 2023.

CW: Reflecting back on 2023, what was your company’s top achievement or strength?
Shah: In 2023, EPP Composites achieved a significant milestone by securing a multimillion-dollar contract for one of the world’s largest copper smelter projects. The project involved the manufacturing of large-diameter (12-meter) and up to 16-meter-tall gas scrubbing columns and tanks/vessels. EPP Composites not only executed the project in a record time frame, but also adhered to stringent test protocols, showcasing our reliability and performance. Our commitment to using 100% internal resources and ensuring long-term reliability through a rigorous selection process positioned EPP Composites as a frontrunner in the industry.
To meet the unique challenges of this project, EPP Composites demonstrated our innovative prowess by developing a highly sophisticated vertical winding process (see video below). This breakthrough technology enabled the manufacturing of equipment with high precision and superior properties, overcoming the limitations posed by the size of the columns and the constraints of available transport methods. The mechanical properties of the laminate produced through the vertical winding process were on par with those manufactured in horizontal production facilities.
We also established a new design office in Chennai in southern India. This office boasts advanced capabilities, enabling complex static and dynamic simulations, surge and stress analysis and finite element analysis (FEA).
Moreover, we diversified our operations by introducing a rebar manufacturing facility at our pultrusion plant. This expansion not only showcased our commitment to innovation but also positioned us to meet the evolving needs of the market.
EPP Composites’ facilities run a variety of manufacturing processes, including pultrusion (pictured).
CW: What goals does EPP Composites have going into 2024, or what opportunities do you see ahead?

CW: In 2023, EPP Composites named fiber-reinforced polymer (FRP) rebar among your innovations. Can you expand on your innovation in this field?
Shah: In the scope of developments in 2023, EPP has notably focused on innovating FRP rebar, representing a significant addition to our product portfolio. This pioneering product is currently being manufactured through an indigenously developed modified pultrusion process, showcasing our commitment to advanced and efficient production methods.
The introduction of GFRP rebar marks a paradigm shift from conventional steel rebar, offering a multitude of advantages, such as corrosion resistance, bonding strength, cost-effectiveness, fire-retardant properties, a tensile strength of 1,000 megapascals (MPa) which is 2-3 times the strength of steel, 20 times higher fatigue strength under cyclic loading conditions, a quarter of the weight of steel (2,100 kilograms per square meter versus 7,800), electromagnetic and thermal nonconductive properties, easy detectability by ground-penetrating radar (GPR), and reduced concrete cracking. Concrete cured with GFRP is also able to use seawater instead of purified water during construction, an economic advantage.
In essence, EPP’s foray into FRP rebar production signifies our dedication to innovation, sustainability and providing our clients with cutting-edge solutions that redefine industry standards.
CW: How does sustainability factor into your operations?
Shah: Sustainability is an integral part of our ethos and operations. We recognize the paramount importance of responsible and eco-conscious practices in today’s business landscape and our commitment to sustainability extends across both our manufacturing processes and the design of our composite products.
In terms of our manufacturing processes:
- To minimize energy consumption, we use energy-efficient machinery, optimized production schedules and integrate renewable energy sources wherever feasible.
- Waste reduction is a key focus. We actively promote recycling within our facilities, ensuring that scrap materials generated during the manufacturing process are systematically collected and recycled.
- We constantly evaluate and optimize our resource use, aiming to minimize raw material consumption and reduce waste. This involves rigorous monitoring of material inputs, efficient inventory management and the adoption of lean manufacturing principles.
In terms of our composite products:
- In product development, we actively explore and incorporate bio-based materials into our composites, reducing dependence on non-renewable resources. Currently, we are exploring the potential use of bio-based polymeric resin systems and the development of natural fiber composites.
- We design our composite products with end-of-life (EOL) considerations in mind. This involves engineering products that are easily recyclable and promoting initiatives for the responsible disposal and recycling of our materials at the end of their lifecycle.
- We conduct comprehensive lifecycle assessments (LCA) for our composite products, evaluating environmental impacts from raw material extraction to EOL scenarios. This helps us identify areas for improvement and make informed decisions to enhance overall sustainability.
At EPP, we view sustainability not just as a selling point but as a responsibility. By continuously integrating sustainable practices into our operations and product development, we aim to set a high standard for the industry and contribute positively to environmental stewardship.
