Type BR

The perforated metal plank type BR is particularly suitable for areas of heavy loads on small contact areas due to its rhomb profile with extra high punching (punched holes 2.5 mm). Here, for example, vehicle navigability on ramps or parking areas are to be considered. A higher slip resistance (R13) is also achieved through the higher punching out of the punched holes.
