Woven Wire Cloth manufacturers of Woven Wire Cloth for over three decades, Haver & Boecker and Standard Group, guarantee the most suitable Woven Wire Cloth for every demand. 0.025mm dia.

Formerly it was termed by ‘No.’ or ‘Mesh’ which is the number of openings in a linear inch. Required Details for Wire Cloth Orders • Mesh Count and/ or aperture width (w) • Roll length • Wire diameter (d) • Roll width • Material • Post weaving fabrications - if necessary • Type of weave - if necessary Post Weaving Fabrications required for a particular application. Where these requirements cannot be met during the actual weaving process, we have developed many post-weaving treatments which are described in greater detail below: Calendering : Strip Cutting : Wire cloth can be cut into strips down to a few millimeters in width. Depending on the type of cloth, lengths of 30 feet to 650 feet can be supplied. Edges : Wire cloth in rolls has either woven edges or cut edges, depending on whether it is woven conventionally with a shuttle or on a shuttleless loom.

Demisters are widely used for such Gas-Liquid Separations and Desalination Plants all over the world. HAST has been fortunate in supplying to a number of such plants with encouraging results.
