Hardware Cloth is a type of wire mesh that is made from a series of closely-spaced wires that are woven together to form a flexible yet durable material. The wires are made of galvanized steel to protect them from corrosion. Hardware cloth is used for a variety of purposes, including as a fencing material for gardens and other small areas, as a reinforcement for concrete, and as a filter in industrial applications. It is also commonly used to protect against small animals like rodents, raccoons and snakes.
