The Reno mattress is a structure made of hexagonal double twisted wire mesh, as per EN 10223-3 (Figs. 1, 2). Reno mattresses are filled with stones at the project site to form flexible and permeable, monolithic structures such as river bank protection and channel linings for erosion control. The steel wire used to manufacture the mattress is heavily zinc-coated soft temper steel. The standard combinations of mesh and wire are shown in Tab. 2. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter . Reno mattresses are divided into uniformly partitioned cells by internal diaphragms.
