Is it true that steel speed humps rattle when vehicles cross them, and if they do, why is this the case?
- They have been incorrectly installed or installed using fixings that are not suited to the road surface.
- The other major reason metal speed humps come loose and develop rattles is poor design. There is a belief that placing a thick rubber underlay beneath a hump during installation will eliminate rattles. WRONG! Many years of experience has proven that humps requiring rubber underlay as part of their installation in fact act like a cookie cutter, destroying the rubber underlay which then leaves the hump loose. The Barrier Group branded Slo-Motion steel speed humps have been designed with large flat pads (up to 4 times the footprint of competitors products). This large footprint eliminates the need for a rubber underlay and reduces the risk of humps working loose, thereby eliminating noise.
