C16 timber is sawn softwood structural timber which has been treated and strength graded
This is timber that has been dried in a kiln (large heated structure) instead of being dried outside under cover.
C4562 graded timber refers to a specific classification of structural timber that meets certain strength and durability standards, primarily used in construction and building applications. The "C" indicates that it is a visually graded timber, with the number representing the strength classification, where C4 signifies a medium strength grade. This grading ensures that the timber is suitable for various structural uses, providing reliability and safety in construction projects. It is commonly used in beams, joists, and other load-bearing applications.
Kiln dried hardwood.
Understanding lumber grades will help ensure you meet design expectations. Structural framing products are graded for their strength and other physical properties, as opposed to appearance products, which are graded for their aesthetic properties.
Strength graded timber used in construction of houses that can withstand greater pressures. Usually it has less or smaller knots (spruce), less cracks and other defects.
Kiln dried timber in woodworking projects offers several benefits, including increased stability, reduced risk of warping or shrinking, improved strength and durability, and a smoother finish.
Lumber is produced from logs in the timber industry through a process called sawmilling. Logs are first debarked and then cut into various sizes and shapes using saws. The cut pieces are then dried and treated to improve their strength and durability. Finally, the lumber is sorted and graded based on quality before being shipped to customers for use in construction and other applications.
Timber can be graded based on visual appearance, strength properties, or a combination of both. Visual grading involves assessing characteristics such as knots, splits, and grain pattern to determine the quality of the timber. Strength grading involves testing the mechanical properties of the timber to ensure it meets specified standards for structural use.
Cedar and pine timber, cloth, purple dye, salt, dried fish, wine.
Visual grading rules for timber are defined by NELMA - The North East Lumber Manufacturers Association. To grade timber, one has to be certified and be able to judge the quality of the wood based on the number of knots, grain, shake and checking. Click on the attached link to visit NeLMA's site.
