Characterisation of Lead Sheet Manufactured Using Traditional Sand-Casting Technique

摘要

Lead sheet is widely used for roofing and flashing applications. Continuous casting and rolling are the most common processes used for manufacture of such sheet. Sand casting of lead sheet is a traditional process used since the Romans. Sand cast lead sheet is presently used for restoration of heritage buildings, churches and cathedrals. It possesses a distinct texture due to the uniqueness of the manufacturing process and is considered a premium product. In the present study, sand cast lead sheet samples were collected and characterised. The observations are then compared with characteristics of continuously cast lead sheet obtained from the literature and are reported in this paper.
