What it's used for

  • Floor joists in domestic and commercial timber frame construction
  • Roof rafters and ridge boards where C24 grade is specified by an engineer or building control
  • Studwork in load-bearing timber frame walls
  • General structural carcassing where span and load capacity require a higher grade than C16

Fitting and handling

Allow the timber to acclimatise on site for at least 24 to 48 hours before fixing, keeping it stacked flat on bearers off the ground and under cover to prevent moisture uptake. Use galvanised or stainless steel fixings throughout to avoid corrosion staining, and where joist hangers or structural connectors are specified, ensure they are rated for C24 timber. Store any unused lengths flat and supported at regular intervals to prevent bowing.

FAQ

What is the difference between C16 and C24 structural timber?

C24 is a higher stress grade than C16, meaning each piece has been tested and confirmed to carry greater loads over longer spans. It is specified where structural calculations or building control require increased strength, for example in floor joists at wider centres or in roof rafters with longer rafter runs.

What does regularised mean on sawn timber?

Regularised timber has been passed through a planer to bring all pieces to a consistent depth, which makes it easier to achieve level floors and plumb walls without packing. The arrises (corners) are also eased to reduce the risk of splits and splinters during handling. The face and edge remain sawn in appearance rather than fully smooth.

Is this timber suitable for use in a structural floor without further treatment?

For most above-ground internal floor joist applications in a ventilated, dry environment this section can be used without preservative treatment. If the timber will be close to or in contact with masonry, near an external wall, or in a poorly ventilated subfloor void, a preservative-treated section should be considered. Always confirm requirements with your structural engineer or building control officer.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

Stunning watch!! Purchased for my boyfriend for his birthday. He is a bigger guy with a larger arm/wrist so the size of this watch looks great on him. He receives a ton of compliments on it, and it still catches my eye every time he wears it. Decent weight without being too heavy (he reports). Perfect to wear as a daily watch or dress up with
