Mallas 
 |
Mallas manufactures square wire meshes from the following wires: stainless steel, bare steel and zinc-coated, copper, brass, bronze, aluminium and other materials at a customer's request. Square wire mesh is a kind of solid woven wire mesh cloth with galvanised or stainless steel wire and is usually identified with the Mesh Opening or the necessary amount of light penetration in mm. |
This type of wire mesh cloth is sold by kilo, in rolls of approximately 25 linear meter. We can make different roll heights for square wire mesh on request, up to 2,000 mm. |

Plain weave square wire mesh:
Plain weave is the most commonly used style of weaving. Every second wire is woven in. Warp and weft wires run over and under each other alt
ernately and interlock. Plain weave meshes guarantee optimum accuracy of apertures or filter pores. These products use wires, which are thinner than the corresponding apertures.
Twilled weave square wire mesh:
In cases where increased wire thickness is required in relation to the aperture size, which yield in the weaving process cannot withstand, this style of weave is chosen. At least two wires are woven in pairs, subsequently displacing a single wire. Mesh stability is controlled by a combination of aperture size and wire strength, and displays a slight diagonal trend.
