Graepel-Round S
The Graepel-Round S is a universal grating for use
on floor surfaces and stairways. It offers adequate
displacement space and a safe footing. Its effectiveness
lies in the combination of
• Large free cross-section (good drainage effect
and weight saving)
•
High load-bearing capacity (benefits in steel
construction and architecture)
The lateral system perforation simplifies
installation.
Load-bearing upward profiling: 3 mm profile
has a higher lump-load bearing capacity than
gratings with less profile or closed surfaces.
The upwardly punched holes ensure a good
anti-skid effect, displacement and drainage. The
holes punched downwards increase displacement
and drainage.
NEW
Program-controlled
perforation groups
Appropriate control of the production plant allows
groups of perforations and stampings to be positioned
separately. This means that not only rectangular
groups of perforations can be punched.
