Single Treads
Connected via Steel stringers of various design, Single Precast Concrete Stair Treads can provide a hard wearing and highly aesthetic solution for transitioning between levels.
Single treads are often designed with structural architectural concrete, reinforced with steel. Finishes include F5 off the form, or may be diamond honed while maintaining NZ standards in slip resistance coefficients.
Single treads have been designed in many different profiles. The more common profiles are :
- Tapered Riser
- Square Riser
- Plank
Nauhria keep and maintain the more common of these moulds profiles in order to provide effective savings in manufacturing costs.
Tread profile requirements outside of these Parameters will require custom formed moulds which will be amortised over the quantity of units required.
