DIN 24531 Galvanized Stainless Steel Stair Tread With Nosing ISO 9001 Approved

  • DIN 24531 Galvanized Stainless Steel Stair Tread With Nosing ISO 9001 Approved
Product Details:

DIN 24531 galvanized platform steel grating stair treads with nosing


Forge-welded gratings produced for stairtreads are produced in the same types as used for platforms and walkways. They are always supplied with serrated, perforated nosing and wel-ded side plates. All stairtreads are inert gas welded, in special jigs.
The stairtreads in accordance to DIN can be produced regar-ding the length with a minus tolerance and furthermore the stair construction can have tolerances. So it may be necessary to verify before srewing the treads if a washer between cheek and stairtread is needed. Thereby possible damages of the welding of the bearings bars to the side plates can be avoided.


Long hole type
For easy fitting to stair stringers, each side plate is always sup-plied with one round and one slotted fixing hole.
Perforated nosing
increases the anti-slip value of the stair-treads and favourably accentuates the leading edge visually.
This is an important contribution to safety.
We reserve the right to supply stairtreads with bearing bars thicker and higher than ordered, at no extra charge.We can offer other types and sizes of stairtreads with perforated nosing,depending on demand.
Stair treads are made according to DIN 24531-1 out of both forge-welded gratings and pressure-locked gratings. Bearing bars 30 x 3 mm and 40 x 3 mm in size are used for selected stair treads. On the front side of treads there is a welded anti-slip perforated stepping edge which reduces the slip hazard and also increases the static load capacity of the tread and optically emphasizes its front side. Treads are provided with side plates 3 mm in thickness with holes for bolts. The dimensions of treads and pitches of holes in the side plate are shown in the table below.
