Lead expansion due to temperature changes, vibrations or changes in pressure is a fact of life, which is why many jobs require a lead expansion joint. An expansion joint has the capacity to absorb small changes in size and shape of the two components being joined without compromising the integrity of the seal. We stock lead guttering expansion joints suitable for most jobs. You can buy your lead expansion joint online from us, or alternatively give us a call to discuss your requirements, place an order or for anything else. We are a lead expansion joint supplier for both trade professionals and private individuals.
