Comparing Viewing Platforms: SHS Piles vs FRP Composite

When it comes to designing and constructing viewing platforms, engineers and architects have a range of materials and techniques at their disposal. SHS (Square Hollow Section) piles and FRP (Fiber Reinforced Polymer) composites are commonly used options. Both materials offer unique advantages and considerations for creating safe, durable, and visually appealing viewing platforms. However, choosing between SHS piles and FRP composites for a viewing platform depends on project requirements and design goals.

Are you in the market for the suitable materials for your next viewing platform project? 

Let us delve into the characteristics of SHS piles and FRP composites, comparing their features, benefits, and potential drawbacks.

SHS Piles: Sturdy Foundations for Elevated Experiences

SHS piles, made from steel, have long been favoured for their structural integrity and load-bearing capacity. These piles provide a solid foundation for viewing platforms that must support heavy loads and withstand external forces such as wind, seismic activity, and dynamic loads from visitors. The inherent strength of steel makes SHS piles an excellent choice for tall or expansive viewing platforms that extend over challenging terrain.

Advantages of SHS Piles for Viewing Platforms:

  1. Strength and Durability: Steel is renowned for its robustness, making SHS piles a reliable choice for long-lasting structures.
  2. Versatility: SHS piles can be easily customized to accommodate various architectural designs and platform layouts.
  3. Stability: The rigidity of steel helps minimizes vibrations and swaying, ensuring a stable and secure experience for visitors.

However, there are some considerations when using SHS piles. The material’s susceptibility to corrosion might require additional protective coatings or maintenance, especially in coastal or humid environments. 

FRP Composites: Modern Innovation for Aesthetically Pleasing Platforms

FRP composites represent a modern approach to constructing viewing platforms, particularly emphasizing aesthetic appeal. These lightweight materials consist of solid fibres embedded in a polymer matrix. FRP composites offer designers greater freedom to create intricate shapes and visually striking structures, making them popular for contemporary and unique viewing platforms.

Advantages of FRP Composites for Viewing Platforms:

  1. Design Flexibility: FRP composites can be moulded into various shapes and forms, allowing for innovative and eye-catching architectural designs.
  2. Lightweight: The reduced weight of FRP materials simplifies transportation, installation, and foundation requirements.
  3. Corrosion Resistance: Unlike steel, FRP composites are highly resistant to corrosion, making them suitable for coastal or corrosive environments.

Despite their advantages, FRP composites might have limitations in load-bearing capacity compared to steel. Engineers must carefully assess the expected loads and stresses on the platform to ensure safety. Additionally, while FRP materials are highly durable, they might exhibit gradual degradation due to prolonged exposure to sunlight and environmental factors. While the choice between SHS and FRP composite piles depends on site conditions and project requirements, both offer advantages for building safe and durable viewing platforms.
