Stay Wire
Stay Wires are galvanized steel wire strands that are used for sustaining mechanical load. Generally they are made up of 6 wires stranded around 1 wire, twisting 7 wires together. A common use for stay wires is in the electricity industry, using the wire to stay power poles and tower structures. Stay wire is made in compliance with BS 183 or other customer specified specifications.
Material: The wire is cold drawn from steel and coated with zinc, the finish strand and the individual wires having uniform quality and have the properties and product characteristics as specified in technical specification.
