WRIGHTMASTER Heavy Duty Galvanized Mesh is hot-dip galvanized and comes in 48 in. x 100 ft. flats. Mesh size is 1/2 in. x 1/2 in. square opening: Made from 16-gauge annealed wire, it is primarily used as screens and fencing. The mesh is cut with scissors and shaped to fit specific projects in your home or property, including window and screen door coverings, chicken coops, rabbit fencing, tree guards, gutters, drains, under eaves, soil screening, and more. Our metal cloth is dipped in plastic after the galvanizing is complete, which greatly reduces the problem of rusting at the welding points and greatly extends the service life.
