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.
Wire mesh in slab on grade is done wrong more times than done right. Wire mesh is not classified as reinforcing in most cases. It is a binder per se. Whether mesh is used on grade or in what is called a composite slab (meaning concrete poured on corrugated metal decking), it is the supporting substrate that makes or breaks the slab. I'm not making excuses, the wire should have been pulled as it was poured, a lot.
