Short sections of used decking (Peachcroft OX14)

Decking - about 25 sections that are cut up to be circa 50cm long each.

Note that this has been pressure treated as external wood and since painted with wood stain but much of this has since worn off. Advice from a Google search is that it shouldn't be burned as this can release the toxins that are impregnated in pressure treatment, so this is really being offered for construction purposes.
