DIN 24531 galvanized platform steel grating stair treads with
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.
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.
