The cantilever comb family comprises a pair of individual elements (combs) with parallel saw-teeth supplied in one metre lengths and laid facing each other.

The combs are either flame cut from a rolled steel plate or aluminium alloy castings. A series of pairs of elements installed end-to-end forms the joint seam.The metal elements are anchored to the main structure by fasteners.

The combs are either flame cut from a rolled steel plate or aluminium alloy castings.

The bottom surface of the joint in contact with the concrete may be coated with epoxy paint (model Wd+) for main structures subject to high humidity and de-icing salts.

Specific features:

• The joints are exceptionally robust due to their simple design
• The comb joint principle provides user comfort and noise reduction
• Exceptionally robust due to the use of tension control bolts to connect the metal elements to the main structure and the choice of materials. They are designed for intensive heavy traffic
• The triangular saw-teeth of the metal elements enable operation with no gap and so ensure perfect road surface continuity and significantly reduced noise over the joint
• Easily accessible anchor bolts and short elements make it easy to maintain and remove the joint with traffic interruption only necessary on the lane in question
