Construction Metals 1 in. x 10 ft. Bonderized Steel Z Bar Flashing

Bonderized Steel Z-Flashing is made from 28-Gauge galvanized steel that has been treated to promote better paint adhesion. It is used to protect the horizontal joints between sheets of siding from water infiltration. The large leg of the metal goes against the wall, leaving the seat and face covering the top edge of the siding. The seat dimension, 1 in., corresponds to the siding thickness.
