LEAD WOOL
Calder is the only UK manufacturer of lead wool. Manufactured on site in Chester using our unique process, our high-quality lead wool consists of thin strands of lead and is primarily used as caulking to seal joints between lead and steel fittings.
It is also a suitable substitute for molten lead when fixing ironwork into concrete.
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.
Available in 25 kg bags
