Technical Information
Technical advice and literature offered by the Lead Sheet Association is based solely on the specification and use of British and European Standard BSEN 12588:2006 rolled lead sheet.
It cannot be assumed to apply to either sand cast or machine cast lead sheet, as the thickness tolerances are wider and more inconsistent than British and European Standard rolled lead sheet. This is particularly relevant when considering thermal movement and appropriate design and fixing methods.
Technical enquiries of this nature regarding sand cast or machine cast lead sheet should be referred to the manufacturers or suppliers of these products.
