A wire strand (10) comprises a plurality of wires (12, 16, 20). The wires comprise a central king wire (12), a first layer (14) of wires (16) arranged around the king wire, and a second layer (18) of wires (20) arranged around the first layer. The king wire is formed of steel having a carbon content of at least 0.3 wt %. Each wire of the first layer is formed of steel having a carbon content which is less than the carbon content of the king wire. Each wire of the second layer is formed of steel having a carbon content which is greater than, or the same as, the carbon content of the wires of the first layer.

A belt for an elevator system includes a plurality of tension members arranged along a belt width and a jacket material at least partially encapsulating the plurality of tension members defining a traction surface, a back surface opposite the traction surface together with the traction surface defining a belt thickness, and two end surfaces extending between the traction surface and the back surface defining the belt width. A metallic coating layer is applied via deposition of solid particles over at least one end surface of the two end surfaces.

The invention relates to the technological field of bridge structures, in particular to a long-service-life PWS cable with replaceable sleeve and shielding gas. It consists of wire strands, wrapping tape covering the wire strands, and a sheath arranged outside the wire strands, and is characterized in that the sheath is covered with an outer protective sleeve and shielding gas is filled between the wires in the wire strands. The wire strands of the present invention is completely under protection in a shielding gas environment which effectively avoids the corrosion of the wire strands; the protective sleeve outside the sheath of the PWS cable is a replaceable segmented and fragmented sleeve structure, which is convenient to be replaced and installed, substantially prolonging the service life of the PWS cable system with great promotional value achieved.
