Hardware cloth comes in 3-, 4-, 5-, and 6-foot rollsâwith 3â² and 4â² being the most common â and in roll lengths anywhere from 5, 25, 50 to 100 feet. The mesh is made by weaving or welding steel wires together, then hot-dipping it in zinc (galvanizing it) to protect it from rust.
Differences between opening size and mesh The difference between mesh and opening size is how they are measured. Mesh is measured from the centers of the wires while opening size is the clear opening between the wires. A two mesh cloth and a cloth with 1/2 inch (1/2) openings are similar.
