Once the stair structure was primed and painted, the oak treads were fitted. The treads are cut from 40mm thick finger-jointed oak as this was the most cost effective way to get sufficiently stable material.
The single stair stringer is made up of twelve individual pieces of 200 x 100 x 12mm section. The brackets for the treads are of 125 x 75 x 8mm section. There was a considerable amount of cutting and welding involved!!
