Most carcassing (constructional) softwood is imported already stamped with a strength grade of either C16 or C24. However, there are circumstances when higher quality grades of softwood, which do not normally come pre-graded, are required with a strength grade.

We can stamp the timber or supply a certificate to show that each piece has achieved the required grade.
|Douglas fir- Larch (Canada, USA)||BS 4978||GS||SS|
|Redwood (imported)||BS 4978||GS||SS|
|Southern pine||BS 4978||GS||SS|
|Western red cedar (imported)||BS 4978||GS||SS|
|Whitewood (imported)||BS 4978||GS||SS|

We can then supply the timber either stamped or with a certificate to show that each piece has met the required grade. These hardwoods include the following:
