Stairs treads type SP and P

Stairs treads type SP and P are produced from resistance welded or pressed gratings according to DIN 24531.
Their advantage is high rigidity, simple assembly and disassembly with high anti-slip protection.
On front side of stairs treads is welded anti-slip stepping edge, which one increasing total bearing capacity of treads. On flanks of tread are forged sides with holes for anchoring nuts.

We are producing stairs treads in typical sizes, for bearing bar 30×2, 30×3, 40×2, 40x3mm and mesh size

for type SP 34x38mm for type P 33x33mm

On request we are producing them also in others bearing bar and different mesh size e.g. 34x51mm or 33x11mm.

Stairs treads we are delivering in atypical sizes too, based on drawing documentation, it is necessary to specify in statement a different types for spacing to drilling holes type n and possibly dimensional axes of holes from edge. Stairs treads are produced from anti-slip gratings too, in all types of serrated edges.

Assembly of stairs treads:

During assembly stairs treads to steel construction we are using galvanised connecting material, which one is completed from screw M12x35 DIN 933, nuts M12 DIN 934, and disc 12 DIN 125A.
If during assembly will be stair between flank/sides and construction, the big-shoulder backlash (danger about deformation side/flank during assembly), is necessary allocate it with another clips before anchoring stairs treads to staircase shoulder.
