Product Overview

Strength-graded structural softwood (C16/C24), kiln-dried, regularised, and treated for carcassing use in floors, roofs, and studwork.

100mm width with a 3m length balances strength and ease of handling for common domestic spans.

Features & Benefits

  • Strength grading (C16/C24): C16 for standard domestic builds; C24 for higher loads and reduced deflection.
  • Factory applied preservative treatment: Protects timber in typical above-ground conditions when installed properly.
  • Kiln-dried & regularised: Helps control shrinkage and ensures even sizing for accurate work.
  • Eased edges: Safer handling and a cleaner finish with reduced splinter risk.
  • Sawn face texture: Provides a stable key for membranes, adhesives, and coatings.
  • Easy to work: Accepts nails, screws, bolts, and hangers.
  • Length - 3m: Suited to common bay sizes and moderate spans.
  • 100mm width: Dependable bearing for floor joists and stud walls.
  • Section size - 47mm x 100mm (4" x 2"): Widely specified in structural carcassing.

Please Note: Finished sizes typically arrive slightly under nominal (often around 2mm less in thickness and 5mm less in width). Colour and surface appearance vary naturally and by treatment batch. Seal all cut ends and notches with a suitable end-grain product.

Applications

  • Floor joists and trimmers: Structural spans for supporting floor loads.
  • Stud walls and plates: Timber framework for partitions and internal walls.
  • Roof members: Rafters and ceiling joists for pitched roofs.
  • Decking subframes: Base framework for raised decking with drainage gaps.

Installation Guidance

  • Respect span limits: Only use within the limits of the specified grade.
  • Use compatible fixings and hangers: Exterior-rated and suitable for treated timber.
  • Re-seal all worked areas: End-grain treatment maintains protection.


Compliance & Performance

  • Strength grading: C16/C24 to BS EN 14081 / EN 338.
  • Service conditions: Suitable for dry internal or covered external use (above ground).
