Stair treads, landings
Stair treads
A stair tread may be built on the basis of platform gratings STD, SERR, SM, WBB, SERR-WBB, SERR-SM, except that it will be equipped with a special side framing which allows for quick assembly of the bearing structure (“the step side”).
It is also equipped with a nonslip front panel thanks to the special perforation on its top.
Worth knowing: Tolerances for parameter B + / – 5 mm Tolerances for parameter L + 0/ – 4 mm

Construction of a stair tread
Termetal offers various types of stair treads whose classification is based on their finishing elements:
| Fig.28. Nonslip panel (ASP)
| Fig.29. Panel ASP-OUT

Standard stair tread (SOZ)
As mentioned before, SOZ stair treads can be constructed on the basis of platform gratings STD, SERR, SM, WBB, SERR-WBB, SERR-SM.
A SOZ tread has a STD side and a nonslip panel – ASP or ASP-OUT.

ESP tread
ESP tread also can be constructed on the basis of platform gratings STD, SERR, SM, WBB, SERR-WBB, SERR-SM.
A ESP tread has a ESP side and a nonslip panel – ASP or ASP-OUT.

FIN stair treads
FIN stair tread can also be made on the basis of platform gratings STD, SERR, SM, WBB, SERR-WBB, SERR-SM.
A FIN stair tread has a FIN side and a nonslip panel – ASP or ASP-OUT.

Landings
The assembly of a landing is similar to that of a stair treads. The key difference is the size of the platform grating used. In addition, the size of the side framing is also greater and, as a consequence, assembly openings have a different spacing, Fig. 33. Landings types available are the same as those of SOZ.
