The Wall floating treads are made of 100% solid beech and come in the colours: dark Havana, bleached, dove-grey, light and dark. Two types of tread are available: an arrival tread (Figs. 1 - 1a) for installation on the floor (with grooves for fastening it to the floor and the side wall), and a wall-mounted tread for fitting in the side wall (Figs. 2 - 2a). There are two different types of landing, a square landing (fig. 3 - 3a) and a pair of triangular landings (fig. 4 - 4a)

The sequence of the Wall treads allows for straight configurations, for use with an opening or a mezzanine, whilst catering for different heights to suit your requirements.

There are no restrictions on where to position the treads on the wall; to make it easier to go up and down the stairs, the value of double the rise (A)+ the going (P) should be between 62 and 64cm (2A + P = 62 - 64cm).

Wall / tread and landings structure Based on the type of tread and landings, grooves have been made (Fig. 7) to hold the side steel structure to be fastened to the vertical wall or to the floor. The internal structure of the tread and landings and the wall fixing plate are made of matt-white painted steel. Special so-called Belleville washers (Fig. 5) allow checking proper fitting of the threaded pins and tightening of the nuts while fitting the structure to the wall (see the installation instructions).
WARNING: the pins should go into the load-bearing structural wall (Fig. 6) by at least 18cm and chemical resin (not provided) for fastening heavy structures should be used.

Seals (indicated in blue) are provided in the kit to be inserted between the treads and the steel structure in order to prevent vibration and noise from being transmitted from the tread to the wall when going up and down the stairs. exploded view of the arrival tread

Wall / technical information The strength of the treads has experimentally been tested with reference to the standards: Eurocode EN 1991-1-1:2002 for Class A civil buildings Appendix A of CEN/TS 15680:2007

Concentrated weight force =Q Rk
Q Rk =3,3 [kN] ≈ 330 [kg] - concentrated vertical force applied to the end of a tread
Distributed weight force =q Rk
q Rk = 4 [kN/m 2] ≈ 400 [kg/m 2] - distributed vertical force applied evenly and simultaneously on all the treads

Wall / tread kit installation When installing the Wall treads, you need to consider that: If there is a mezzanine, the floor thickness (S) must be at least equal to the rise (A) + 5cm. If there is a floor opening, you need to check the following conditions: - The floor thickness (S) must be between the rise (A) + 5cm and 42cm - The floor opening width (L2) must be greater than 80cm - The floor opening length (L1) must be greater than 260cm and the side wall must be load-bearing.

If L2 is between 80 and 90cm, use 80cm wide treads (Table 1) If L2 is greater than 90cm, you can use 90cm wide treads (Table 2) Looking at the table, based on the dimensions of the structural wall, the floor opening and the finish chosen, you can find the number of tread kits you need and order the corresponding ninedigit code.

Example: If you want to install WALL treads with a light finish and with a floor opening and you have these dimensions: H=273 cm, L2=92 cm, L1=340 cm, S=30 cm (L2 > 90 cm, so look at Table 2)
