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.
