Whether you’re a professional deck builder or a DIY enthusiast, we have the perfect subframe to ensure durability, stability, and compliance with Australian standards.

Clearance Requirements for Subframes

Choosing the right subframe and maintaining proper clearance is essential for building a long-lasting, stable deck. Here are the requirements:

• H3 Subframes: Ideal for above-ground decks, requiring a minimum clearance of 300mm from the ground. This ensures proper ventilation and protects the timber from moisture and decay.
• H4 Subframes: Specifically designed for on-ground or low-clearance decks with a height of 150mm or less, offering superior protection against termites, rot, and ground contact.
• Aluminium Subframes: Perfect for elevated or premium installations, requiring a minimum clearance of 30mm to allow for proper airflow and prevent moisture-related corrosion.
