Timber is used in projects of all sizes, from mini garden projects at home to large-scale construction projects worldwide. It offers strength and versatility while giving every project a natural feel. In Sheffield, timber is always in high demand, but choosing the right grade of timber for your project is so important.
The two most well-known and biggest sellers for us in Sheffield are c16 & c24 timber. In the blog, we will break down the differences between them, their uses, and which to choose for your next project.
C16-graded timber is a type of softwood that is graded for use in indoor projects. The “C” in C16 stands for “conifer,” while the “16” refers to the timber’s strength. 12 different timber strength grades can be used within the construction industry in the UK. These grades are set out by the British Standard in the BS5268.
This timber is normally sourced from fast-growing softwood species like pine or spruce. All this timber will undergo structural and visual grading to ensure it meets the standards within the industry. C16 is especially known for being reliable. But not to be used for extreme load bearing. Some of the factors that are taken into account include knots, splits along the grain, the slope of the grain, woodworm holes, shape, and wane.
Some of the key features of C16 timber include the durability & strength of the timber, as well as the versatile options the timber gives you.
C16 timber has a minimum strength of 16 N/mm², which means it can support a certain amount of weight. It's strong enough for many common household construction applications. The combination of strength and durability is what makes it so good for these types of projects.
One of the main benefits of using C16 is the versatile range of ways this timber can be used. You can use it for roofing, flooring, wall framing, and decking. It’s strong enough for any of these projects and is still very cheap compared to higher-graded timber.
C16 timber can be treated to enhance its durability and resistance to decay, insect infestation, and fungal growth. Which is important if your timber is sold outside.
Our C24 timber is a higher grade of structural timber that is often grown slower for denser softwood. Which will help with the increased strength and durability of the C16 timber. All our C24 timber is fully graded and machine-tested to make sure it is consistently high quality.
C24-grade timber can be used in the construction of floor joists, roof joists, and timber framing; it can also be used in many other applications, both internally and externally. Perfect for deck framing and pergolas, our C24 has minimum stamping on it so that it doesn't impact the looks of your project.
C24 timber has a minimum strength of 24 N/mm², which makes it stronger than C16 timber. It's suitable for heavy load-bearing and knot-free finishes.
C24 timber can be untreated or pretreated. It should be treated and sealed if used outside to prevent rot, warping, and damage from insects and weathering. Treated C24 timber can last for many years without degrading.
C24 timber is more expensive than most other grades of wood. But with good reason. C24 is more costly than other types, mainly due to the slower growth time and increased strength.
You must understand the key difference between C16 & C24 timber, as it will help you make the correct decision about the grade of timber you need for your next project. C24 timber is highly valued for weight-bearing projects, making it a top choice for outdoor structures.
The main factor to consider when you are choosing between C16 and C24 timber is what you are going to use the timber for. If you are doing an indoor residential project on a budget. Then C16 should be your choice. If you are constructing a project that requires strength or a feature that demands exceptional strength. Then C24 is worth the extra cost.

When selecting timber for your project, make sure you are always confirming the following:
What are you going to use the timber for, how much weight will it be holding, and will it be indoors or outside? Each factor will affect the choice you need to make.
The amount of moisture in the wood can affect its durability. So opting for kiln-dried timber will minimise the risk of warping in the future.
If your timber is going to be used outside, ensure the timber is pressure-treated for resistance against pests and decay.
Look for FSC- or PEFC-certified timber to guarantee sustainability on all your timber.
