Hog panel, also known as a hog wire panel or cattle panel, is a type of fencing material used to contain and control pigs or other livestock. It is made of heavy-duty galvanized steel wire that is welded together in a progressive grid pattern, creating a strong and durable barrier. The panels come in a variety of sizes and can be used for both permanent and temporary fencing. They are often used in agricultural settings, but can also be used for residential and commercial applications.
