GRP I-Beams, made from glass reinforced isophthalic polyester resin, represent a revolutionary advancement in structural engineering materials. These beams are crafted using pultruded GRP profiles, a process that combines fibreglass and resin to create components with exceptional strength and durability.

GRP I-Beams are distinguished by their lightweight properties and significant resistance to corrosion, making them a superior alternative to traditional materials like steel or wood in many applications.

These I-Beams are specifically designed to support heavy loads while maintaining a high strength-to-weight ratio. This makes them ideal for a variety of applications in construction, especially in environments where resistance to chemicals, moisture, and other deteriorative factors is essential.

The thermal and electrical non-conductivity of GRP makes these beams safe for use in industries where such properties are crucial.

GRP I-Beam offer a host of advantages that make them highly suitable for a wide range of structural applications. Here are some of the key benefits:
  • Corrosion Resistance: One of the most significant benefits of GRP beams is their inherent resistance to corrosion. Unlike metal beams, GRP does not rust, corrode, or degrade when exposed to harsh chemicals, salty environments, or moisture. This makes them particularly useful in industrial settings such as chemical plants, marine applications, and any location where environmental conditions are a concern.
  • High Strength-to-Weight Ratio: GRP beams are remarkably strong yet lightweight compared to traditional materials like steel or concrete. This high strength-to-weight ratio makes them easier and more cost-effective to transport, handle, and install, reducing overall project costs.
  • Thermal and Electrical Insulation: GRP is naturally insulative, providing excellent thermal resistance and electrical non-conductivity. This makes GRP beams ideal for use in electrical and thermal applications where metal beams would pose a safety risk.
  • Durability: The durability of GRP beams extends the lifespan of structures with minimal maintenance required. They are designed to withstand wear and tear and environmental impacts, which reduces the need for frequent replacements and repairs.
  • Design Flexibility: GRP beams can be manufactured in various shapes, sizes, and colours to meet specific project requirements. This flexibility allows architects and engineers to design innovative structures that can be both functional and aesthetically pleasing.
  • Sustainability: With a focus on environmental impact, GRP beams are a more sustainable option than many traditional materials. They require less energy to produce and can be recycled at the end of their service life, contributing to a reduction in environmental footprint.
These benefits make GRP I-Beams an attractive choice for builders and engineers looking for reliable, long-lasting, and efficient structural solutions.

GRP structural profiles are essential components in a variety of construction and engineering projects, offering versatility and enhanced performance characteristics. Here’s an overview of some commonly used GRP structural profiles:
  • Angle: GRP angles are L-shaped profiles that are typically used in frame construction, providing stability and support at corners and connections.
  • Square Box: This profile is shaped like a box with square dimensions. It is commonly used for framing, enclosures, and as ducts or conduits where rigidity and uniformity are important.
  • Channel Section: The channel or C-shaped profile provides a reliable support system in construction. It's used for framework, rails, and as structural support where flat back face mounting is needed.
  • Flat Plate: GRP flat plates are used extensively in cladding, as well as in the construction of platforms and walkways where a flat, continuous surface is necessary.
  • I-Beam: One of the most popular GRP profiles, the I-Beam, is used primarily for structural support in construction of large buildings. Its I-shaped cross-section provides high resistance to bending and torsion.
  • Wide Flange Beam: Similar to the I-Beam, the Wide Flange Beam has flanges that are wider than standard, providing greater load-bearing capabilities. This profile is ideal for heavy-duty applications.
  • Round Tube: GRP round tubes are used in a myriad of applications, including protective sleeves, handles, and lightweight structural columns. Their round shape offers uniform strength in all directions.
  • Plank: GRP planks are often utilised for their slip resistance in walkways, platforms, and stairways. They offer a sturdy, durable surface with excellent safety features.
Each of these profiles highlights the adaptability and efficiency of GRP as a material choice. By choosing the appropriate profile based on structural needs and environmental conditions, engineers and architects can optimise the durability, cost-effectiveness, and performance of their projects. These GRP structural profiles ensure long-term resilience and reliability, making them a preferred choice for innovative building solutions.

Thermal conductivity is a crucial factor in GRP profiles, especially in applications where insulation from heat or cold is required. GRP materials generally have low thermal conductivity, which means they do not easily transfer heat.

This property makes them ideal for use in environments where thermal stability is essential, such as in HVAC systems or in industries where thermal insulation is necessary to protect equipment or processes.
Yes, GRP I-Beam profiles can be manufactured to meet different structural and performance specifications, including the E17 and E23 grades. The E17 grade is suited for general-purpose applications, while the E23 grade is tailored for higher performance requirements, offering enhanced durability and strength for more demanding applications.

The specification for pultruded profiles will detail the performance characteristics and suitability of each grade.
