Metallic expansion joints comes in many different form and design, all which contains one similar unit, the bellow.

Bellow is the flexible component built to perform a wide range of engineering tasks.

They can be used to accommodate displacement whether laterally, angular or axially.

With proper choice of materials and designs (Combination of 1 or more bellow units) these joints can handle almost all sorts of displacement and fluid content.

Our plain stocked bellows come in 2 models of P7000 and P7100.
