Modern specifications usually comprise a sequential coating application of paints or alternatively paints applied over metal coatings to form a âduplexâ coating system. The protective paint systems usually consist of primer, undercoat(s) and finish coats.
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.
A knot is similar to an interlock in the sense that it holds the mesh down. The difference is, an interlock will pull the mesh down, and hold the string itself tight (so the tightness of the mesh relies on the sidewall string being tight), while a knot, literally ties a knot onto the mesh.
