Agricultural Construction Timbers
Unseasoned and Kiln Dried Purlins & Yorkshire Boarding
BSW also supply a range of timbers that are perfectly suited for agricultural purposes.
Horizontal structural timber purlins used in roof construction help to support the loads from the roof deck or sheathing and are supported by the principal rafters and/or the building walls.
Unseasoned Timber
Used in construction applications where an unseasoned (not kiln dried) and ungraded product may be acceptable or beneficial.
Large Sections and Long Lengths
All strength graded timber for agricultural buildings is wet graded either visually or by machine. BSW can offer machine wet graded to class C16 and visually graded timber is available subject to species availability and agreement.
