LOWDECK – H4 Deck Joists – 5.4m

Description

LOWDECK – Australia’s First GL8 Structural H4 Engineered Bearers & Joists for Ultra-Low Decks

Meet LOWDECK – the innovative engineered timber solution designed specifically for on-ground and ultra-low decking. As Australia’s first GL8 structural bearer and joist system treated to H4, LOWDECK finally gives installers, builders, and DIYers a purpose-made subfloor option for decks that sit close to the ground.

Why LOWDECK?

When framing timbers are on the ground or within 150 mm of soil, they must be termite resistant and rated for in-ground durability. Standard decking timbers don’t cut it here — but LOWDECK does.

According to the Technical Design Guide – Forest & Wood Products Australia – Domestic Timber Deck Design, the correct specification for this situation is H4 treatment or better, with in-ground durability Class 1 or termite-resistant performance. LOWDECK has been engineered from the ground up to meet this requirement.

Engineered for Harsh Australian Conditions

LOWDECK is treated to H4 using Koppers Micro® Timber Treatment Technology, providing long-term protection from:

• Fungal decay

• Termites

• Borer and insect attack

This treatment system is backed by an impressive 50-year warranty, giving you peace of mind when building in high-risk environments.

Built Strong – GL8 Structural Rating

Manufactured to a GL8 engineered structural grade (roughly equivalent to F7), LOWDECK offers reliability and consistency far beyond regular softwood decking joists. Each piece is also double-sealed with a premium oil-based primer, delivering an additional layer of defence against the elements.

The Smarter Choice for Ultra-Low Decking

LOWDECK provides a durable, easy-to-install and affordable alternative to steel or aluminium framing systems. It’s also a significant upgrade from standard H3 treated pine joists, offering superior treatment, strength, and protection while remaining simple to work with using normal timber tools and fixings.
