A Structural Surface, Not Just a Step
A stair tread carries point loads well beyond what a normal floorboard sees, which is why we mill ours from dense, Class 1 or Class 2 durability hardwood rather than lighter decorative species. Blackbutt gives a pale honey tone with a fine, even grain; Spotted Gum runs from pale brown through to rich chocolate with a distinctive wavy figure. Both machine cleanly to a nosing profile and take stain or clear coating without blotching. Standard tread stock is supplied dressed on four sides with a pencil-round or bullnose nosing along the leading edge, ready for the stringer housings and riser rebates to be cut on site or in the joinery shop. Thicker sections are available where open-riser or floating-stair designs put more of the load through the tread alone.

Working With Stair Treads
Treads should be housed into stringers or supported on cleats per standard staircase construction practice, with fixings concealed from the walking surface wherever possible. Pre-drill for any exposed screw fixing to avoid splitting near the nosing, and allow for natural movement across the width of the board. Once fitted, treads are typically sanded flush and finished with a floor-grade coating that matches the adjoining flooring — a hardwearing polyurethane or oil, applied in the same number of coats as the floor for a consistent sheen. Re-coat high-traffic treads more frequently than the surrounding floor, since stair nosings wear faster than open floor area.
