Paint Grade Open House Stair String (pair)

40mm Open House Timber Stair String (pair)

For 40mm open house paint grade strings we use second grade hardwood such as Melunak with poor colour consistency that can't be used as polish grade.

Elevate your staircase with our precision-machined 40mm thick solid timber open house string, expertly crafted for strength, accuracy, and a clean modern look in Queensland homes. For custom floor finishes or non-standard requirements, see our stair configurator to order custom strings. These strings are sold as a pair and delivered as a left hand and right hand string together.

Dimensions & Profile:

• Thickness: 40mm
• Going: 240mm or 250mm
• Rise options: 170mm, 175mm, 180mm, 185mm or 190mm
• Upper and lower finishes set to 12mm – can be packed up or cut down on site to suit finished floor levels
• Precision-machined pockets designed so our 40mm open house treads, 30mm top riser and 40mm Nosing simply slip into place

This string is made specifically for open house stairs, where the treads are housed into the string without the need for wedges. It works equally well as a wall string or outer string and pairs perfectly with our 40mm Open Timber Stair Treads for a clean, secure fit.

Perfect for both new builds and renovations, the 40mm construction delivers solid performance in family homes while giving a neat, continuous side profile that suits contemporary, coastal, or traditional designs.

Key Benefits:

• Easy assembly with accurately cut pockets for a straightforward slip-in tread fit
• Smooth, sanded surfaces ready for your choice of stain, oil, or clear finish

All products are delivered raw, pre-finished sanded to 100 grit.
