This cantilevered staircase is available for various load categories, including T1 for stairs without significant traffic, with T2 and T3 for higher load categories. The standard T1 tread has been designed and tested to take a 750kg load, giving only a 3mm deflection at the end of a 950mm tread.
Tread widths start from 800mm and rise to 1250mm. These are available in 50mm increments. Goings (tread depth) are available in sizes of 260mm, 280mm, 300mm, and 320mm. The thickness of treads can vary from 80mm upwards. Larger treads can be manufactured.
There are various options to provide building regulations standard guarding. A glass wall can be erected alongside the staircase, or other balustrade designs can be incorporated.
