Pressed floor gratings PR are made by cold pressing of the supporting tape and the transverse tape. Stair treads already have a welded anti-slip tread edge on the front of the step and sidewalls with pre-drilled mounting holes at the prescribed spacings. Standard DIN 24531.
Standard DIN 24537.

TPR / 34×33 / 30×2 / Zn / L x B
Pressed floor gratings PR, eye 34×33, hot-dip galvanized
Carrying tapes standard: 30×2; 30×3; 40×3
Support dimension (L): direction of support strips (150 mm – 1500 mm)
Non-bearing dimension (B): economic 240; 270; 305 mm (side panels)
Mounting holes are pre-drilled on the sidewalls at the prescribed spacings n = 120; 150; 170 mm.

Anti-slip toothing of pressed steps (XTPR) is available for all types of carrier tapes.

The design of pressed PR stages made of stainless steel is available in a tape version of 30×2, 30×3, 40×2 and 40×3.

SUPPORTING DIMENSION (L), ie the direction of the load-bearing strips, is always perpendicular to the supporting structures. It is the distance between the supports that the grate spans the carrier straps. We dimension the load-bearing tape according to the required load-bearing capacity for a specific distance between the supports in lengths of 150 mm – 1500 mm (applies to gratings as well as steps).

NON-BEARING dimension (B), ie the direction of non-bearing bars, is always PARALLEL with the supporting structure. It is effective to apply as many grates as possible with an economical non-load-bearing dimension B = 1000 mm (full width of the production line). Atypical non-load-bearing dimensions B ≠ 1000 mm (400 – 1400 mm) usually have only end or edge pieces.
The agreed standard non-bearing dimensions B = 240 apply to the steps; 270; 305 mm. Mounting holes are pre-drilled on the sidewalls at the prescribed spacings n = 120; 150; 170 mm.

In the record, the BEARING dimension (L) is always entered in the first place and the BEARING dimension (B) in the second place, ie
L x B. The exchange of load-bearing and non-load-bearing dimensions has a fundamental effect on the safety, load-bearing capacity and service life of the grate.
