Which Material Delivers Better Long-Term Performance?

Offshore wind platforms operate in one of the world’s harshest environments. Constant exposure to salt spray, seawater, humidity and UV radiation places enormous demands on decking materials.

While steel has long been the traditional choice, Fiber Reinforced Polymer (FRP) is rapidly becoming the preferred alternative due to its superior corrosion resistance, lightweight design and lower maintenance requirements.

Steel Decking: Strength with Limitations

Steel offers high structural strength and has been widely used in offshore construction. However, prolonged exposure to marine environments presents several challenges:

• Susceptible to corrosion and rust
• Requires regular painting and maintenance
• Heavy weight increases transportation and installation costs
• Higher lifecycle maintenance expenses

These factors can significantly impact operational efficiency and long-term project costs.

Why FRP Is the Better Choice

Outstanding Corrosion Resistance

Unlike steel, FRP does not rust or corrode, making it ideal for continuous exposure to seawater and salt spray.

Lightweight Construction

FRP weighs significantly less than steel, reducing structural loads while simplifying transportation and installation.

Lower Maintenance Costs

FRP requires no anti-corrosion coating or repainting, helping reduce maintenance frequency and lifecycle costs.

Enhanced Safety

FRP decking provides excellent slip resistance, electrical insulation and long-term durability, improving safety for offshore personnel.
