GRP Pultruded Profiles

Engineered Composites – Proudly supporting one of the UK’s leading Civil engineering universities, Kingston University London.

Case Study


Engineered Composites, the UK’s leading GRP supplier with over 37 years of experience, was chosen as the primary supplier of GRP palisade fencing for a prestigious project in the power generation sector. This landmark project involved the construction of a new £86 million substation by SSEN Transmission, expected to have a significant impact on reinforcing the East Coast transmission network facilitating the connection of new renewable generation in the North of Scotland to the grid. Engineered Composites’ extensive range of GRP fencing products, along with their expertise in the field, have made them the preferred choice for this critical infrastructure initiative.

Project Overview

The construction of the substation, known as Alyth, spanned a period of 28 months, encompassing various stages of planning, design and implementation. Alyth substation, strategically located, is a key element of the SSEN Transmissions’s comprehensive plan to reinforce the East Coast transmission network. Its vital role is to enable the connection of new renewable generation in the north of Scotland to the national power grid, facilitating the efficient transmission of clean energy to where it is needed most.
Our GRP palisade fencing products provide numerous benefits for power generation sector, specifically for the Alyth substation project:
The substation was designed to have an operational capacity of 275kV initially, with provisions for future expansion to 400kV operational by 2026. This expansion would provide the necessary capacity increase to accommodate significant upcoming renewable energy projects in the region. As part of the substation’s integration with the existing 275kV overhead line (OHL)that stretches from Fetteresso to Tealing and Kincardine, the construction of three new transmission towers was also undertaken.


Engineered Composites were proud to be chosen as the primary supplier of GRP palisade fencing for the Alyth substation project. We proved our ability to deliver exceptional solutions to the unique requirements of the power generation sector. The combination of durability, easy installation, low maintenance, security features, and aesthetic appeal provided by Engineered Composites’ GRP palisade makes it the perfect choice for critical infrastructure projects such as Alyth substation.

Unparalleled Durability and Strength

Our GRP palisade fencing is renowned for its exceptional Strength-to-weight ratio. This reinforced plastic material is highly resistant to weathering, corrosion, and impact, offering long-lasting protection against the harsh environmental conditions typically encountered in the power generation sector.

Lightweight and Easy Installation

Our GRP fencing panels are lightweight , simplifying transportation and installation processes. The reduced weight not only facilitates quicker installation but also minimises labour costs, contributing to the overall project efficiency.

Minimal maintenance Requirements

All our high-quality GRP materials are resistant to rust, decay and chemical exposure. The low maintenance nature of GRP fencing translates into long-term cost savings for the power generation sector.

Enhanced Security Features

GRP palisade fencing provides exceptional security for critical infrastructure like Alyth substation. The robust design, featuring pointed or rounded tops. Acts as an effective deterrent against potential intrusions. GRP’s non-conductive nature further ensures enhanced safety around electrical installations.

Aesthetic Appeal

We understand the importance of blending functionality with aesthetics. Our GRP products are available in a range of attractive designs, carefully crafted to integrate with the surrounding environment.
