Galvanized steel roll flashing, sometimes referred to as valley metal, is used in a wide variety of applications. The galvanized metal roofing flashing is typically field formed and used in a flashing or trim capacity for various areas of a home which may include valleys, chimneys, fascia, endwalls, sidewalls, and many others. Galvanized metal flashing has the best strength of comparable flashing materials but the galvanized metal flashings can eventually rust, especially along cut or exposed edges. Union offers mill finished galvanized steel flashing in widths from 10" to 20" and up to 50' in length.
