Introduction:

The design of Wanbao wave joints is based on the latest insights and technical developments in expansion joints engineering.

Instead of bolted and wave shaped edge plates, the edge beams which are firmly anchored into the adjacent concrete are being designed in a sinusoidal shape.

The straightly running impact edge does no longer exist. The “wave phase”which is the distance between 2 inflection points of the edge beams, is selected in such a way that when an axle passes the joints, at least one of the two wheels passes the expansion joint in skew angle, whereby the noise emission is greatly reduced.

The patented and flexible sealing element guarantees by way of a superior clamping mechanism the water- tightness of the expansion joint.

Quality guarantee:

If need more friction, special patent can be processed to meet requirement

l  Gap width up to 100 mm – like SCF100 finger joints

l  Reduced noise emission – same as sinus plates system

l  Maintenance free – like standard single seal expansion joints

l  Can be made from Carbon steel S355 or Stainless steel A304

Economical, safety, easy flexable
