Steel-Framed Decks

Built for strength, style, and long-term performance. Our steel-framed decking systems are designed to outperform traditional timber sub-frames in durability and reliability.

By combining engineered steel framing with high-quality timber or composite decking boards, we deliver decks that are low-maintenance, structurally strong, and perfectly suited to NSW conditions.

Why We Use Steel-Framed Decking

Unlike traditional timber-framed decks, steel deck frames provide superior structural integrity and lifespan. This ensures your deck remains level, strong, and visually appealing for years to come.

  • • No rot, warping, or termite damage
  • • Greater strength and load capacity
  • • Precision-engineered structure
  • • Ideal for sloping or challenging sites
  • • Long-term durability with minimal maintenance

Steel framing also allows for cleaner lines and a modern architectural finish.
