The world of wood can be complex, with terms and phrases which aren’t in the daily vocabulary of most people. Here, we hope to clear a few things up and help you understand where your timber comes from. Remember, if you need help with absolutely anything, give us a call.

 

Our range of machined softwood products is produced using mainly Redwood. Whitewood is used for some products where it is better suited to the end use. Redwood and Whitewood used for these products is graded visually to internationally accepted rules as follows;

 

GRADES

 

Unsorted - Wood of the highest qualities, minimal sound knots, minimal imperfections, excellent appearance.

Fifths - Good quality, few sound knots of small size, few other small imperfections.

Sawfalling - Mix of unsorted and Fifths as above.

Sixths - More visible imperfections suitable for less prominent applications.

 

CUTS

 

Centre Logs - Mainly 38mm and 50mm

Boards - Cut from the outer part of the log to minimise the number of knots and other defects

2 or 3 ex - Products produced by re-cutting a larger section; eg; 25mm ex 50mm or 19mm ex 38mm

 

STRENGTH GRADED STRUCTURAL SOFTWOOD

 

 

These products are usually referred to as carcassing products and are primarily Whitewood (Spruce). They are strength graded as follows;

TR26 - Specifically for the production of engineered Truss Rafters

C24 - The highest, generally available, strength grade for general building applications

C16 - General purpose structural grade.
