Metal Bellows

Why obtain bellows and metal fabrication from different sources?

Weldmac can design and construct the entire assembly for you. With our facilities and staff, we can work with you to manufacture even the most complex metal expansion joint assembly. We will apply our high tech capabilities and experience to ensure that your project is completed to the exact specifications you need.

Because nobody could do it for us

Weldmac entered the bellows and expansion joint market because we could not find any that met the specs we needed for our clients. Now we build them ourselves. Whatever your requirements, we are capable of constructing a bellows product that will meet or exceed your expectations. Over the decades Weldmac’s work has been subjected to the tightest tolerances and scrutiny by our demanding and distinguished clients. The result has been loyal clients.
