In addition to our core product range containing a wide selection of circular expansion joints, Belman also provides rectangular expansion joints.
Many design options
We design and manufacture rectangular expansion joints with single and multi-convolution bellows. These units can be made with no size limitation since they can be supplied in sections for transport and reassembly on-site.
Rectangular expansion joints can be designed to accept a combination of axial and lateral movement. When signiﬁcant lateral movement is to be absorbed, a twin-bellows arrangement is usually required. Alternative corner arrangements can be supplied including single and double mitre and when necessary with rounded corners. Frames and bellows are available in a wide range of materials, sizes and conﬁgurations to suit individual customer requirements. These expansion joints are invariably used as customised solutions to expansion problems in rectangular ducting; they are purpose-designed and manufactured to match the customer’s unique requirements.
