Metsä Wood C16 Cls Timber - (L)2.4M (W)89mm (T)38mm

C16 is a strength class for timber, indicating its load-bearing capacity and stiffness. Timber graded C16 is certified for structural applications, meaning it has met specific requirements for strength, making it suitable for elements like floor joists, roof timbers, and wall studs.

This CLS timber is primarily intended for internal structural use. If it is to be exposed to outdoor elements or damp conditions, it must be treated with appropriate wood preservatives to protect it from moisture, rot, fungi, and insect attack. Untreated timber will degrade quickly outdoors.

You can cut this timber using standard woodworking tools. A hand saw, circular saw, or miter saw are all suitable, depending on the precision and volume of cuts required. Always use appropriate safety gear, including eye protection.

Store CLS timber flat on a level surface, ideally elevated off the ground using bearers or battens. Ensure it is kept in a dry, well-ventilated area away from direct sunlight, rain, and extreme temperature fluctuations. Covering it with a tarp or plastic sheeting is recommended if stored outdoors, ensuring air circulation to prevent moisture buildup.

Yes, as C16 strength-graded timber, it is suitable for use in load-bearing internal walls, as well as floor and roof structures, provided it is used in accordance with approved architectural plans and building regulations.

CLS (Canadian Lumber Standard) timber is specifically dimensioned, planed on all four sides, and has rounded edges, making it easier and safer to handle and work with. Regular timber, often referred to as 'rough sawn,' may have varied dimensions, rougher surfaces, and sharp edges, requiring more preparation for structural applications.

Warping is often due to improper storage. Ensure timber is stored flat, off the ground, and protected from moisture and rapid temperature changes. For minor warps, careful clamping during installation might work, but severely warped pieces should not be used in structural applications.

Ensure your saw blade is sharp and appropriate for cutting timber. A blade with fewer, larger teeth (for cross-cutting) or more teeth (for finer cuts) will improve results. Ensure the timber is securely clamped before cutting.

Splitting often occurs when fastening near the ends or edges of the timber. Pre-drill pilot holes before inserting screws, especially for harder woods or when working close to the timber's perimeter. Ensure screws are of appropriate gauge and length.

This indicates excessive moisture exposure. Move the timber to a dry, well-ventilated area to allow it to dry out naturally. If mildew is present, wipe it away and ensure continued dry storage. Do not use damp timber in structural applications as it can affect strength and encourage rot.
