Routered Stair Stringers are precision-cut timber components designed to provide strong, consistent support for residential and light commercial stair construction. Manufactured from 200mm x 50mm H4 dressed radiata pine, these stringers are CCA treated, dressing grade, and kiln dried, making them suitable for exterior and exposed applications where durability and dimensional stability matter.

At WBS Henderson, we carry routered stair stringers in stock from 1 step (350mm rise) through to 10 step (1925mm rise), available ex yard for quick and easy project turnaround. For larger builds, special orders are available from 11 step through to 15 step, along with a complete range of 250mm x 50mm stringers to suit higher rises and custom stair requirements. If you need something outside our standard range, our team can source the right option to match your job.
