What is f72 mesh?
Reinforcing/concrete mesh is a welded wire fabric, prefabricated steel reinforcement material. It has a rectangular or square grid pattern and is produced in flat sheets. It is used to provide tensile strength and crack control to structural concrete elements.
Does REO mesh rust?
Reinforcing bar and mesh often arrives on site with some rust on it. This mill-scale provides a protective layer in the right conditions but if stored externally or if the steel has been handled, this mill-scale may be disturbed leading to light rusting.

Rectangular mesh is used to reinforce concrete in one direction more than another. Made from D500 wire, prefabricated trench mesh is used to reinforce concrete footings. Standard L grade ribbed wire mesh, with a galvanized corrosive element barrier.
Can you use rusty REO?
Re: Slab reinforcement – can rusty mesh be used? Surface rust is fine, it actually helps the concrete to ‘grip’ the steel. Loose / flakey rust is a different issue! Once the steel is in place with the correct cover (at least 40mm) no further corrosion should occur.
