DON’T BE FOOLED BY FAKE, this original patented design is and has been UK Manufactured for over 25 Years. The Surface Mounted Flow Plate (Patent No’s 22385658, 22705338) has been designed to offer advantages over the sunken design. This product is strong enough to withstand the heaviest goods vehicle, or with the flap reduced to 115mm, will provide the strength and flexibility to allow all types of vehicles (standard design maximum weight 1 tonne per axle) to travel over them. Another advantage these plates offer is eliminating the problem of piercing roadway surfaces, no more digging holes as these simply bolt down to the surface providing an easy yet effective traffic control solution.
