The Finishing Timber That Ties a Staircase Together
A riser fills the vertical gap between one tread and the next, closing the front of the step and giving a staircase its finished, continuous appearance from the side. Because risers aren't load-bearing, we mill them thinner than treads — typically 12–19 mm — while still supplying them in the same Blackbutt or Spotted Gum stock used through the rest of the range, so colour and grain stay consistent from floor to tread to riser. Some staircase designs use open risers — no riser board at all, leaving a gap between treads — which is a legitimate design choice for contemporary or feature staircases, but most residential and commercial projects specify closed risers for safety, sound-deadening and finished appearance. We supply riser stock dressed and ready to cut to the exact rise dimension of your staircase.

Working With Stair Risers
Cut risers to the exact rise dimension of your staircase and fix into the stringer housing or rebate per standard construction practice, with the top edge typically housed slightly under the tread nosing above for a clean, gap-free joint. Pre-drill near board edges to avoid splitting thin-section stock. Finish risers with the same coating system as the treads and flooring for visual consistency, applied before or after installation depending on your joiner's preferred sequence. Because risers see far less direct wear than treads, they generally need recoating far less often once the staircase is in use.

Most residential and commercial staircases use 12–19 mm riser stock, since the board carries no structural load. The right thickness depends on your housing detail and personal preference — thicker stock gives a slightly more substantial look and feel underfoot at the step edge.
