Established in 1974, METZ is designed to be used as a non-toxic lead replacement for flashings. Made from a special zinc alloy, it is light and malleable and can be used in the same way as traditional lead flashing but without any associated health problems. We stock the Metz replacement flashing which has a self-adhesive backing to bond it securely in place as well as the Metzseal Sealant. This can be used for sealing Metz flashing into a wall or upstand chase, is hard-wearing, long-lasting and can be applied in wet or damp conditions.
