F7 H3 LOSP Treated Pine

F7 H3 LOSP Treated Pine: Engineered for Strength, Built for the Outdoors

When it comes to outdoor construction, timber must do more than just look good, it must perform under pressure and withstand the elements. F7 H3 LOSP Treated Pine is a high-grade structural timber that delivers on both fronts. Rated for strength and treated for longevity, it’s the ideal choice for builders, landscapers, and DIY enthusiasts seeking reliable timber for above-ground outdoor applications.

This timber is engineered to meet the F7 structural grade, ensuring it can handle significant loads in framing, decking, and general construction. It’s also treated to H3 hazard level using LOSP (Light Organic Solvent Preservative) technology, which provides strong protection against termites, rot, and mold, without the harmful effects of older treatment methods.

Key Features & Benefits

• ✔
  Structural Grade F7: F7 denotes a high level of bending strength and stiffness, making this timber suitable for load-bearing roles in walls, floors, and roof framing. It’s engineered to perform consistently across a range of structural applications.
• ✔
  H3 Hazard Level Treatment: H3 treatment protects timber used above ground and exposed to the weather. It defends against termites, fungal growth, and decay, ensuring your outdoor structures remain safe and intact for years.
• ✔
  LOSP Technology: LOSP is a low-toxicity preservative that penetrates deeply into the timber without altering its appearance or structural integrity. It’s a cleaner, more environmentally friendly alternative to traditional treatments like CCA, making it ideal for residential and commercial projects where sustainability matters.
• ✔
  Dimensional Stability: Kiln-dried and treated under controlled conditions, F7 H3 LOSP Treated Pine offers excellent dimensional stability, reducing the risk of warping, cupping, or splitting over time.
• ✔
  Compliance with AS 1604: This timber meets the requirements of Australian Standard AS 1604, ensuring it’s safe, reliable, and suitable for structural use in Australian conditions.
• ✔
  Easy to Work With: Straight-grain pine makes cutting, fastening, and joining easy, saving time and effort on-site. It’s compatible with nails, screws, and adhesives commonly used in timber construction.
