Most people are aware of the link to the Roman Empire and the first water systems using lead pipes, but far fewer know of the application of lead in Nuclear Medicine. Modern imaging techniques and treatments such as Positron Emission Tomography rely on lead to provide radiation shielding  for both the patients and medical staff.

Lead is used as a weather resistant seal on roofs, as an additive for free machining steel , batteries that keep the internet & cell phones working rely on lead terminals. Our defence industry uses lead for ballast and radiation shielding. Copper foil is produced using lead anodes as is the production of ingot copper . Galvanising & Chrome plating anodes are made from lead along with other novel items such as weights for curtains and ballast weights for sub-sea cables.

Our scientific community is dependant upon lead for shielded rooms to aid them in synchrotron radiation research, whilst historic buildings are still refurbished using Calder lead sheet.

So whether ancient or modern, large or small, simple or complex -  Calder hold the answer to all of your lead engineering needs.
