What are the benefits of strength grading?
Strength grading is undertaken primarily to provide timber of sufficient strength for a particular function,e.g.a floor joist or a roof truss. At the same time strength grading helps to ensure that both the design and the timber sizes specified are economical.
What is strength grading?
BSW produce strength graded timber to specifications laid down
in British Standards - BS4978 for visual grading and BS EN 519 for machine grading.Timber is graded to strength classes.The most commonly specified grade for softwood carcassing is C16.
How do BSW treat timber?
Timber is loaded into treatment vessel and an initial vacuum
applied which evacuates the timber cells of air.The cylinder is flooded under vacuum with TANALITH? E wood preservative. Hydraulic pressure is applied,which forces the preservative deep into the structure of the timber.A final vacuum extracts the excess preservative solution,which is pumped back to storage. BSW offer timber treated with either a green or brown finish.
What type of preservative does BSW Timber use?
BSW Timber utilise pressure treatment plants at our sawmills.
We now use the latest generation of wood preservative,TANALITH E,which is approved and used in over 30 countries worldwide. TANALITH E provides a unique,highly effective preservative protection system for timber based on copper triazole technology. The copper is derived from recycled resources and is well known for its fungicidal and insecticidal properties.The triazoles (tebuconazole and propiconazole) are commonly used to protect many of the crops we eat.
How do BSW kiln dry timber?
The timber is pushed into either batch or progressive kilns on railed bogies.The difference between the two types of kilns involves the static positioning of the stacks within the batch chambers,with the temperature and humidity changing through the drying cycle.In the progressive chamber the kiln packs move forward approximately every 5 hours through changing humidity and temperature.The sequence of changes is called a kiln schedule and the operators use different schedules for different sizes and species of wood.
What are the benefits of kiln drying?

- Improved insulation
- Improved strength
- Lighter weight
