Custom-Fabricated for Duct Systems and Non-Circular Piping

Rectangular expansion joints are designed specifically for ducts and rectangular pipelines to absorb movement caused by thermal expansion, vibration, and mechanical forces. These joints are ideal for HVAC, exhaust, and flue gas systems where round bellows cannot be used. Shivam Cast Products offers fully customizable rectangular bellows to fit any duct layout and space constraint.
