Devices for speed limitation
BHV Rubber produce and selling devices for speed limitation. Devices for speed limitation on public roads aremanufactured as two types:
Type A – modular structure, end and central parts
Type B – hemispherical modules
Devices for speed limitation type A are made from rubber mixture and metal or textile insertion reinforcement in areas of fixing, with applied elements of reflective properties.
The slip and speed limiting devices type B are madeof bicolour rubber and metal or textile insertion.
They are used at temperatures between -40 and +70 ° C, also are resistant to air, ozone, water and atmospheric agents.
