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.

Offers Complete Privacy
Color: Black, Size: 132in-Large Metal Base
We tried others that were nice but this particular room divider adds total privacy. We were looking for that. Easy to assemble. There is no gap if you position each petition close enough. The guality is very nice. Exactly what we were looking for.

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!

4/5 Stars
Size: 4 Panel-88'', Color: Black
Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.

Great product and worth the money.
Size: 4 Panel-88'', Color: Black
Portable and stable. Perfect size and gives me the privacy I need when working from home. Stability is great as long as you place the stands correctly it won't wobble. I love it.
