C24 sawn regularised structural timber at 47mm x 150mm (6x2) is a kiln-dried softwood graded for load-bearing applications including floor joists, roof rafters and structural framing. Kiln dried to 20% moisture content or below for improved stability and consistent site performance.

Specifications

What it's used for

• Floor joists spanning medium to long distances in domestic and commercial builds
• Roof rafters and ridge members where C16 does not meet span or load requirements
• Load-bearing studwork partitions and structural wall framing
• Decking subframes and ground-level support structures requiring a stronger section

Fitting and handling

Store timber flat and off the ground under cover before use, allowing it to acclimatise to site conditions for at least 48 hours where possible. Fix using appropriate structural joist hangers, framing anchors or direct nailing at centres specified by your engineer or building control officer. Where the timber will be in contact with masonry, concrete or exposed to moisture, apply a preservative end-treatment to cut sections on site.

FAQ

What is the difference between C16 and C24 structural timber?

C24 is a higher strength grade than C16, with stricter limits on knot size and slope of grain. It is specified where longer spans, heavier loads or tighter joist centres mean C16 does not provide adequate structural capacity. Your engineer or building control officer will confirm which grade is required for your project.

What does regularised mean on sawn timber?

Regularised timber has been machined to a consistent cross-section after sawing, so each length is the same depth and width. This makes it easier to achieve flat, level surfaces when installing floor joists or rafters without having to pack individual members. Edges are also eased slightly to remove sharp arrises.

Is this timber suitable for use as decking joists or a subframe?

Yes, the 47mm x 150mm C24 section is widely used for decking subframes where a stiff, strong bearer is needed. If the joists will be in ground contact or close to it, you should use a preservative-treated grade.
