Technical Specification
All John Brash Timber Scaffold Boards are graded to BS 2482:2009:
We can supply three categories of Scaffold Board:
-
38x225 BSI 1.2m support centre - these boards can either be visually or machine graded.
- 38x225 BSI 1.5m support centre - these boards can only be machine graded.
- 63x225 BSI 2.5m support centre - these boards can be either visually or machine graded.
Dimension:
When measured at a reference moisture content of 20%:
-
38mm thick boards: +/-2mm in thickness and/or +/-5mm in width. Length +/- 25mm.
- 63mm thick boards: +/-3mm in thickness and/or +/-5mm in width. Length to the system manufacturer tolerances. Generally 63mm boards need to be precision end trimmed to suit the system they are to be used in.
NOTE: Crosscutting does not affect the structural integrity of the board and the
board will still comply with BS 2482. Visually graded boards – all defects will
have already been visually assessed. Machine graded boards – the board will have
been mechanically assessed along its length.
See our scaffold board brochure for the table of strength properties from BS
2482:2009.
