Top 7 Treated Pine Structural Timber Applications for Renovation Projects

Enhance your renovations with treated pine structural timber from I Got Wood—durable, affordable, and perfect for decks, fences, and pergolas.

Few materials in home renovation offer the same versatility, durability, and value as treated pine structural timber. Favoured across Australia for decks, pergolas, and garden walls, it delivers exceptional strength, termite resistance, and long-lasting performance. At I Got Wood, we provide premium treated pine products trusted by both DIY renovators and professional builders to achieve outstanding results.

Here are seven of the most popular ways to use treated pine in your next renovation project.

1. Deck Substructures – Decks are an Aussie favourite for creating outdoor spaces to relax, entertain, and enjoy the sunshine. Using treated pine structural timber for bearers, joists, posts, and stair framing ensures strength and lasting performance. Choose H3 for above-ground framing and H4 or H5 for in-ground posts to keep your deck sturdy and safe for years.

2.  Pergolas and Arbours – A pergola or arbour adds instant style and function to any outdoor space, and treated pine is the perfect material for building strong, weather-resistant structures. Use H3 for beams and rafters and H4 for posts set in soil to ensure lasting durability. We offer high-quality treated pine beams and posts ready to bring your outdoor project to life.

3.  Verandas and Covered Patios – Verandas are timeless additions to Australian homes, offering shade and year-round outdoor comfort. Treated pine is a popular choice for framing, rafters, and posts because it’s strong, affordable, and easy to work with. Use H3 or H4-rated timber for weather-exposed areas and finish it with a quality stain or oil for lasting beauty and protection.

4.  Carports and Outdoor Roof Structures – Treated pine is ideal for carports, gazebos, and outdoor roof extensions, offering strength for structural loads while remaining lightweight and easy to work with. Use H3 for above-ground framing and H4 or H5 for posts in contact with the ground, paired with galvanised or stainless fixings for durability. We supply all the treated pine grades you need to build safe, long-lasting outdoor structures.

5.  Exterior Stairs and Handrails – Stairs, handrails, and balustrades endure constant weather exposure, making treated pine a reliable and durable choice. Use H3-treated pine for treads, risers, and rails that meet AS 1604 standards for outdoor performance. Its easy-to-work nature allows you to shape and finish each piece for stairs that look stunning and stand the test of time.

6.  Fences and Screening – A well-built fence not only defines your boundaries but also enhances privacy and elevates your home’s street appeal. Treated pine is ideal for fence posts, rails, and screening panels, with*H3 suited for above-ground sections and H4 or H5 for posts in soil. We supply premium treated pine products that make fence building easy, affordable, and built to last.

7.  Retaining Walls and Landscaping Projects – For landscaping renovations, treated pine sleepers and posts offer unbeatable strength, durability, and easy installation. They’re perfect for garden retaining walls, terraced beds, steps, and edging projects. Our H4 and H5-treated pine sleepers meet Australian standards and are built to withstand tough outdoor conditions.
