Case Study


The Copenhagen Kastrup Airport in Denmark required a blast wall fence as part of its security measures to mitigate the potential risk of explosive threats. After careful consideration, the decision was made to utilise Engineered Composites GRP profiles for the construction of the blast wall fence. This case study examines the reasons behind this choice and highlights the benefits that GRP profiles offer in the airport environment, surpassing those of steel.

Reasons for Using GRP Profiles:

1. Lightweight: One of the primary reasons for choosing GRP profiles over steel was their lightweight nature. GRP profiles are significantly lighter than steel, making them easier to transport, install, and handle during construction. This resulted in reduced construction time and manpower requirements.

2. Corrosion Resistance: The Copenhagen Kastrup Airport is located in a coastal area, where the corrosive environment due to saltwater and other harsh elements poses a significant challenge for traditional steel structures. Unlike steel, GRP profiles are highly resistant to corrosion, making them an ideal choice for the airport’s blast wall fence. This characteristic ensures long-term durability and reduced maintenance costs.

3. Fire Resistance: GRP profiles possess excellent fire resistance properties. In the event of a fire, GRP profiles will not contribute to the spread of flames or release toxic fumes. These characteristics enhance the overall safety of the airport infrastructure and protect passengers and staff.

4. Reduced Maintenance: GRP profiles are virtually maintenance-free compared to steel. Unlike steel, GRP does not require regular painting or coating to prevent corrosion. This translates into significant cost savings and reduced downtime for maintenance activities, allowing the airport to operate smoothly without interruptions.

5. Durability: GRP profiles are known for their high strength-to-weight ratio, making them extremely durable. They can withstand harsh environmental conditions, including extreme temperatures, UV radiation, and chemical exposure. This durability ensures a longer lifespan for the blast wall fence, minimizing the need for frequent replacements or repairs.


The use of Engineered Composites GRP profiles for the construction of the blast wall fence at Copenhagen Kastrup Airport proved to be a wise choice. These profiles offer numerous advantages over traditional steel, including lightweight construction, corrosion resistance, design flexibility, electrical insulation, non-magnetic properties, fire resistance, reduced maintenance, and exceptional durability. By opting for GRP profiles, the airport enhanced its security measures while simultaneously achieving long-term cost savings and maintaining a visually appealing and sustainable infrastructure.
