A belt for an elevator system includes a plurality of tension members arranged along a belt width, 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 applied from a liquid solution is positioned over at least one end surface of the two end surfaces.

A method for fabricating a steel wire cable having a ZnAl alloy plating, the method including: arranging steel wires according to an arrangement rule at a cross section of the steel wire cable; controlling a length of the overall cable by a length of a central standard wire; twisting a bunch of the steel wires comprising a zinc-aluminum alloy plating with a torsion angle of between 2 and 4; wrapping the steel wire bunch with a polyester wrapping bandage and covering a resulting product with a double-layered protective polyethylene sheath; anchoring the two ends of the steel wire cable by anchors using fillers; and coiling the finished-product of the steel wire cables.

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.

A strand (20) for a cable bolt (14) comprises a plurality of metallic elongated members (22, 24) twisted together. At least one of the elongated members has a corrosion resistant coating (54) and surface deformation, so as to improve the bodig efficiency and the anchorage of the strand.

A threadlike metallic or metallized reinforcer, for example a thread, film, tape or cord made of carbon steel, at the periphery of which is positioned a layer of metal referred to as surface metal chosen from copper, nickel and copper/nickel alloys, is characterized in that this surface metal layer is itself coated, at least in part, with at least one layer of graphene; preferably, there is grafted, to this graphene, at least one functional group which can crosslink to a polymer matrix. This reinforcer of the invention is effectively protected from corrosion by virtue of the graphene present at the surface; advantageously, it can be adhesively bonded directly, without adhesion primer or addition of metal salt, to an unsaturated rubber matrix, such as natural rubber, by virtue of the possible functionalization of this graphene.
