Lead Wool

Calder is a leading provider of lead wool to the defence industry. As one of the only UK manufacturers of Lead wool we process our lead wool in-house at our Chester site which ensures that each piece of lead wool is quality checked by our lead specialists.

Lead wool consists of thin strands of lead and is primarily used as caulking to seal joints between lead and steel fittings. Supplied in a range of lead alloy specifications from 0-0.5% antimony to Chemical A, the specification of lead wool is dependent on application.
