Production
| Pressure-locked gratings Stairtreads |  |
|
Stairtreads are produced in the same types as the pressure-locked gratings. They are always supplied with serrated, perforated nosing and welded side plates. All stairtreads are inert gas welded in special jigs. By this means the formation of slag and a distortion during the galvanizing process can be avoided. Lichtgitter stairtreads are conformal and even.
Long hole type
For easy fitting to stair stringers, each side plate is always supplied with one round and one slotted fixing hole.
Perforated nosing

Perforated nosing increases the anti-slip value of the stairtreads and favourably accentuates the leading edge visually. This is an important contribution to safety.
