  • the present invention also relates to a fabric comprising a colored metal rope and to the use of such a metal rope in architectural and decorative applications.
  • a metal rope with wires having a surface of stainless steel At least those wires exposed to the surface of the rope are coated with a transparent polymer, which is selected from the group consisting of thermoplastic polyesters, polyimides, polyamides and polyphtalamides, or a copolymer thereof.
  • a wire with a surface of stainless steel can be a common stainless steel wire or can be a wire with a metal core, e.g. a core of plain carbon steel, and with an external layer of cladded stainless steel.
  • thermoplastic polyester is used as polymer.
  • Thermoplastic polyester has the advantage of giving a good adhesion with the stainless steel wire and of having a low degree of moisture absorption. The good adhesion level is obtained without pickling treatment on the stainless steel wire so that the initial bright aspect of the stainless steel wire is not reduced. The low degree of absorption further guarantees that this bright aspect is kept for a long time.
  • This thermoplastic polyester is selected from the group consisting of . polyethylene terephtalate, polybutylene terephtalate, polyethylene naphtenate or any copolymer comprising polyethylene terephtalate, polybutylene terephtalate or polyethylene naphtenate.
  • the transparent polymer comprises a transparent organic coloring agent, which can be added to the polymer in the form of small grains in a carrier of a similar or same polymer.
  • a transparent organic coloring agent which can be added to the polymer in the form of small grains in a carrier of a similar or same polymer.
  • This embodiment offers the advantage of various colors depending upon the concentration and type of coloring agent : metallic like colors and fluorescent colors may be applied to the stainless steel wire in this way.
  • the coloring agent together with the transparency of the polymer and the bright aspect of the stainless steel wires give to the rope a typical metallic look.
  • thermoplastic polyester exhibits a good resistance against abrasion. Furthermore, thermoplastic polyester has a relatively low coefficient of friction.

  • a metal rope according to the invention can be used in the structural field, i.e. in the building and architectural field, and in the decorative field.
  • a first application is the use of the metal rope as stay rope or stay strand for suspension bridges with a high span length of support.
  • the individual steel wires of the metal rope often have diameters exceeding
  • Metal ropes for this application often comprise more than one strand of twisted wires.
  • a second application is the use of the metal rope as stay rope or stay strand for roof support or for outside wall support. Roofs for sport stadium, sport halls, airport buildings, exposition halls can be suspended on such metal ropes. The possible application of various colors is also more important in this second application than in the first application.
  • a third application is the use of the metal rope for stays and supports of antennas and masts.
  • the metal wire rope according to the invention can be applied for the suspension of lighting apparatus, for the building of stands at expositions and exhibitions, for the interior and exterior design of shops, suspension or lifting of objects in theaters.
  • the wire diameter is usually much smaller than the wire diameter of ropes used in the architectural field.
  • the fabric comprising the colored wire rope may also have various building and decorative applications.
  • the fabric may be used as a ballustrade for terraces, stairs and bridges.
  • the fabric may function as a ceiling in public buildings.
  • the fabric may also be used as a decorative woven structure for inner or outer walls. The fabric can even be used in furniture.
