FRP Decking Vs Timber Decking: Which Performs Better Over Time?

The hidden costs of timber that stack up fast

Timber might be the traditional go-to for decking, but it doesn’t always stand the test of time. Especially in tough industrial environments. From coastal walkways to industrial platforms, timber is often the weakest link. It’s heavy, prone to rot, and demands regular maintenance to keep it safe and compliant.

While timber can look great when first installed, the ongoing time and money it takes to keep it that way can be a real issue. And when it’s exposed to salt, moisture, or harsh UV? The deterioration is inevitable.

Why more projects are switching to FRP decking

Fibre Reinforced Plastic (FRP) decking is built for resilience. It’s designed to handle the extremes that timber struggles with. PermaStruct® FRP Decking, has become a smarter, more durable alternative across civil, marine and industrial applications.

Here’s how it holds up over time:

  • No rot, rust or corrosion in marine or high-moisture areas
  • Lighter weight than timber, reducing load and easing installation
  • Zero maintenance required to stay compliant and safe
  • UV stable so it keeps its appearance longer
  • Fire retardant options available for added peace of mind

Put simply, it delivers performance without the constant upkeep. That means long-term savings, better compliance, and less time spent on repairs.

Time isn’t kind to timber

Whether it’s a public boardwalk or a commercial platform, timber degrades. It cracks, warps, absorbs moisture and eventually becomes unsafe. Even treated timber isn’t immune.

For local governments, builders, or industrial operators, this creates a cycle:

  • Regular inspections
  • Ongoing repairs
  • Full replacements far earlier than expected

That’s not just inconvenient. It’s costly.

Low maintenance isn’t just marketing. It’s a game changer

One of the strongest benefits of FRP decking is what you don’t have to do.

With timber, regular maintenance is part of the deal. You expect to oil it, check for termites, and budget for repairs. With PermaStruct® FRP decking, that routine is barely there.

Instead of spending resources managing deterioration, you’re focused on what matters. Whether it’s public safety, project timelines or reducing total lifecycle costs.

A material that lasts, even in harsh conditions

PermaStruct® FRP Decking has been designed to go the distance, even in corrosive or remote environments. From mining infrastructure to coastal platforms, it thrives where timber fails.

You get:

  • Consistent quality across every installation
  • Confidence in long-term performance
  • Reduced downtime from repair-related closures

This is about more than durability. It’s about delivering smarter solutions that are fit for purpose from day one.

Smarter choices start with smarter materials

Choosing decking materials shouldn’t be based purely on upfront cost. It’s about lifecycle performance, compliance, and safety. FRP delivers on all fronts, helping builders and asset managers reduce risk without compromising on quality or versatility.

As designers of high-strength, low-weight composite solutions, we believe in doing things differently. And doing them better. FRP decking is just one way we deliver on that promise.
