Blackbutt Closed House Tread

30mm Standard Timber Stair Tread

Elevate your staircase with our precision-machined 30mm thick solid timber stair tread, expertly crafted for durability, comfort, and a seamless fit in modern Queensland homes.

Dimensions & Profile:

• Thickness: 30mm (finished at 29.5mm to fit nicely into strings)
• Going: 240mm or 250mm
• Total width: 260mm or 270mm (includes a 20mm overhang/nosing for a classic, elegant projection that enhances safety and aesthetics)
• Front edge: Attractive 6mm pencil round nose profile – a subtle, smooth rounded edge that provides a refined look, reduces sharp corners
• Underside: Features a 20mm deep riser groove precision-milled to securely accommodate standard 18mm thick risers (perfect for a clean, flush installation with no visible gaps)

This tread is versatile and suitable for both closed riser housed stairs (traditional enclosed designs with visible strings) and closed riser sawtooth stairs (invisible strings). Each tread requires a riser to complete the step assembly.

Perfect for both new builds and renovations, the 30mm thick construction ensures long-lasting performance in family homes, while the pencil round nosing and overhang create a timeless, sophisticated finish that complements contemporary, coastal, or traditional designs.

Key Benefits:

• Easy installation with pre-machined groove for quick riser fitting
• Smooth, sanded surfaces ready for your choice of stain, oil, or clear finish
• Naturally beautiful grain and tones that add warmth and character

Available in both 1m and 1.5m lengths to suit your project. All products are delivered raw, pre-finished sanded to 100 grit.

Blackbutt, a premium Australian native hardwood (Eucalyptus pilularis), boasts a clean, uniform appearance with pale golden-brown to straw tones and a straight, even grain—occasionally accented by subtle gum veins for added rustic charm. Exceptionally durable and fire-resistant, with high density and strength, Blackbutt excels in high-traffic areas and is ideal for stair components that demand longevity and low maintenance. Its neutral palette complements contemporary and coastal  interiors, while its natural toughness makes it suitable for treads, stringers, risers, and handrails that stand up to everyday family use.
