Configurable off the shelf in 1 to 17 treads in a continuous pair, Dual Stringers can cover up to
3150mm in vertical height.
Suitable for interior or exterior applications, These Stair Stringers are robust and weather resistant, hot-dip galvanised for maximum corrosion resistance.
Features
Designed with walking comfort in mind, Our Stair Stringers have an incline angle of 34.75 degrees with steps placed at a consistent 175mm rise allowing for a ‘going’ distance of 250mm.
^ Dual Stringers comply with the requirements of the National Construction Code Volume 2 for Class 1 and 10 buildings Part 3.9.1 when installed with treads at least 50mm thick. The minimum 50mm thick tread is to meet the dimensional requirements of Figure 3.9.1.4 to prevent a 125mm sphere from passing between the treads.
Configuring Dual Stringers
To calculate the number of treads required simply:
1. Measure the vertical height from the ground to the finished floor level of the landing.
2. Divide the height by the rise of each tread (175mm)
3. Round the result to the nearest whole number, then reduce by one for the top landing. The result is the number of treads required.
