This architectural drawing is Design of mess reinforcement in 2D. Reinforcement mesh, or steel fabric, is a premade lattice of rebar used to improve the lateral strength of concrete slabs, walls, and other constructions. The most common size is 150x150mm with a 4mm thickness. A reinforcing mesh is set inside the concrete during construction. After the slab is set, the mesh inside it offers additional strength against pressure. For more details and information download the drawing file.
