To control appearance and assure straightness, consistancy, strength and stability stringers and long handrail posts are manufactured from solid wood laminations. Shorter handrail posts are manufactured by jointing and planing non-laminated solid wood. Stringers are supplied in matched sets with each stringer shipped slightly longer than required. Stringer ends are marked to indicate where plumb and level cuts should be made if the surrounding structure of the building has been made exactly to plan. The actual cuts are made on site to fit the building.
Treads are pre-cut to the correct lengths.
Landings are pre-assembled in the shop and taken apart for economical shipping. Handrail posts and handrails are shipped a few inches longer than required so they can be cut to fit on site. Wider widths are available. Stair installation involves cutting the stringers to fit the mating portion of the building, then assembling the treads into the mortises of each stringer. The top end of the complete stringer and tread unit is then lifted and fastened in its final position.
