H4 Treated Pine Sleeper 200×75

The H4 Treated Pine Sleeper 200x75mm is the go-to choice where greater mass and structural depth are required. Pressure-treated to Hazard Class H4 under Australian Standards, it is fully rated for in-ground and soil-contact use — standing up to termites, fungal decay, and the demanding Australian climate across a wide range of landscaping and construction applications.

The extra 25mm of depth over the 200×50 profile delivers noticeably greater rigidity and load resistance, making the 200×75 the standard specification for retaining walls over 300mm in height, heavy-duty garden terracing, and anywhere you need the confidence of a more substantial sleeper. It’s a firm favourite with both professional landscapers and experienced DIYers across Australia.

Sourced from plantation-grown Radiata Pine, the sleeper’s rough-sawn face brings a warm, natural character to any outdoor setting. It can be finished with a quality timber oil, stain, or paint to complement your landscape design.
