Why GRP is the Future of Data Centre Construction
Data centres, the backbone of our digital age, demand cutting-edge construction materials that can meet stringent performance, safety, and sustainability requirements. As the global demand for data storage and processing continues to surge, driven by technologies like cloud computing, AI, and IoT, the need for resilient, efficient, and sustainable infrastructure has never been greater. GRP is increasingly being recognised for its outstanding qualities in this high-tech, high-demand environment..
GRP, also known as fiberglass, is an advanced composite material made by reinforcing plastic with fine fibres of glass. Traditionally used in industries like waste water treatment, railway and high rise construction, GRP has recently found a new and important application in data centre construction. Its unique combination of properties makes it an ideal choice for addressing some of the most pressing challenges in building and maintaining modern data centres. In this article, we will explore why GRP is emerging as a leading material in data centre construction, comparing it to traditional materials such as steel and aluminium, and how its non-conductive nature enhances electrical safety in these critical environments.
The Growing Importance of GRP in Data Centre Infrastructure
Data centres are complex facilities where uptime, safety, and efficiency are paramount. Constructing and maintaining them requires materials that can endure harsh conditions, resist corrosion, maintain structural integrity under heavy loads, and offer long-term cost savings. This is where GRP excels.
Data centres often house sensitive electronic equipment that generates a significant amount of heat. Efficient thermal management, fire safety, and preventing electrical faults are top priorities. Traditional materials like steel and aluminium, while commonly used, have limitations when it comes to corrosion resistance, electrical conductivity, and flexibility in design. GRP, on the other hand, brings a new dimension to data centre construction by offering enhanced durability, electrical insulation, and resistance to environmental factors such as moisture, chemicals, and extreme temperatures.
Comparing GRP with Traditional Materials: Steel and Aluminium
When comparing GRP to traditional construction materials like steel and aluminium, several critical factors highlight why GRP is becoming the preferred choice in data centre construction:
-
Durability and Corrosion Resistance
Steel and aluminium are widely used in the construction of data centres for structural components, handrails, ladders and other infrastructure elements. However, both materials have inherent limitations when exposed to certain environmental conditions. Steel, for instance, is prone to rust and corrosion, especially in humid or chemically aggressive environments. While galvanized steel or coated steel can offer some protection, these treatments eventually degrade over time, leading to increased maintenance costs and downtime for repairs.
Aluminium, though naturally resistant to corrosion, can be vulnerable to certain chemicals and saltwater exposure, making it less ideal in coastal or industrial locations. Moreover, both steel and aluminium conduct electricity, which can pose risks in environments with sensitive electronics and high-voltage equipment.
In contrast, GRP is inherently corrosion-resistant, making it an excellent choice for data centres located in humid, coastal, or chemically aggressive environments. Unlike steel and aluminium, GRP does not rust, oxidize, or degrade when exposed to moisture, chemicals, or salts. This resistance significantly reduces the need for maintenance, extending the lifespan of the infrastructure and minimising operational disruptions.

Weight and Ease of Installation
Another key advantage of GRP over steel and aluminium is its lightweight nature. Steel, while strong, is heavy and difficult to work with during installation, requiring specialised equipment and larger crews. This can lead to higher installation costs and longer project timelines. Aluminium, although lighter than steel, still requires careful handling and can be difficult to mould into complex shapes.
GRP, in contrast, is incredibly lightweight – up to 75% lighter than steel and 30% lighter than aluminium – making it much easier to transport, handle, and install. Its lightweight nature allows for faster, more efficient installation, reducing labour costs and project durations. Additionally, GRP can be moulded into complex shapes and customised to meet specific design requirements, offering more flexibility than metals.

Strength and Load-Bearing Capacity
Despite being lightweight, GRP is extremely strong and can support significant loads. This makes it an excellent choice for pedestrian load-bearing structures in data centres, such as raised flooring systems, access platforms, ladders, and walkways.
Moreover, GRP exhibits excellent impact resistance, meaning it can withstand accidental knocks or stress without denting or bending, which can be a common issue with aluminium. This durability is especially important in areas with high foot traffic or in facilities where heavy equipment is frequently moved.
The Non-Conductive Properties of GRP: Enhancing Electrical Safety in Data Centres
One of the most critical considerations in data centre construction is electrical safety. Data centres are home to vast amounts of electrical wiring and sensitive electronics that need to be protected from electrical faults, interference, and short circuits. This is where GRP’s non-conductive properties provide a clear advantage over metals like steel and aluminium.
Both steel and aluminium are conductive materials, meaning they can carry electric current. In a data centre, where even a small electrical fault can cause significant downtime or damage to equipment, the use of conductive materials can increase the risk of short circuits, grounding issues, and electrical interference.
GRP, on the other hand, is inherently non-conductive. This makes it an ideal material for applications where electrical safety is paramount, such as in GIS access platforms, risers, and raised access floors. By using GRP in these applications, data centres can significantly reduce the risk of electrical faults, ensuring a safer operating environment for both equipment and personnel. Additionally, GRP’s non-conductive nature helps prevent electromagnetic interference (EMI), which can disrupt the operation of sensitive data centre equipment.
Fire Resistance and Safety
Another significant advantage of GRP in data centre construction is its fire-resistant properties. Data centres must comply with strict fire safety regulations, as the consequences of a fire in such a facility can be catastrophic. Our GRP grating and profiles can achieve Class 1 Fire Rating to BS476 part 7, EN 13501 and ASTM E84-19A. Our grating and profiles are flame retardant with a classification of BFL S1 in accordance with EN13501.
Moreover, in the event of a fire, GRP does not emit toxic fumes, unlike some other materials. This contributes to a safer environment for personnel and minimises the potential for damage to sensitive equipment from smoke and corrosive gases.
Environmental Benefits and Sustainability
Sustainability is becoming an increasingly important consideration in the construction of data centres, as companies seek to reduce their carbon footprint and environmental impact. GRP is a more environmentally friendly option compared to traditional materials and has a low carbon footprint.
GRP’s long lifespan and low maintenance requirements further enhance its sustainability credentials. Unlike steel and aluminium, which require frequent maintenance and replacements due to corrosion and wear, GRP’s durability ensures that infrastructure built with this material will last for decades without the need for constant repairs or replacements. This reduces both the environmental impact and the total cost of ownership.
Conclusion: The Future of Data Centre Construction is GRP
In a world where data centres are becoming increasingly vital to global infrastructure, the materials used in their construction must evolve to meet the demands of efficiency, safety, and sustainability. GRP offers a compelling alternative to traditional materials like steel and aluminium, with its superior corrosion resistance, lightweight strength, non-conductive properties, and fire safety.
As data centres grow in scale and complexity, GRP’s unique combination of durability, cost-effectiveness, and safety features will play an increasingly critical role in shaping the future of data centre construction. For operators seeking to build facilities that stand the test of time – both in terms of performance and sustainability – GRP is the material of the future.
