Standard:aisi 316 grade stainless steel Capacity:2000ton/month Stainless steel cable & stainless wire rope is highly corrosion resistant & decorative. Excellent for marine rope rigging, stainless steel cable railing, architectural cables, cable balustrades and cable display systems. Stretch is a characteristic of all wire ropes; constructional stretch initially Steel wires for wire ropes are normally made of non-alloy carbon steel with a carbon content of 0.4 to 0.95%. The very high strength of the rope wires enables wire ropes to support large tensile forces and to run over sheaves with relatively small diameters. In the so-called cross lay strands, the wires of the different layers cross each other. In the mostly used parallel lay strands, the lay length of all the wire layers is equal and the wires of any two superimposed layers are parallel, resulting in linear contact. The wire of the outer layer is supported by two wires of the inner layer. These wires are neighbours along the whole length of the strand. Parallel lay strands are made in one operation. The endurance of wire ropes with this kind of strand is always much greater than of those (seldom used) with cross lay strands. Parallel lay strands with two wire layers have the construction filler, seale or warrington. We offer an extensive range of stainless steel wire & cable. In 1x19, 7x7 and 7x19 constructions in aisi 316 marine grade stainless steel. Sizes 1.5mm to 19mm.

Capacity:2000ton/month Prestressed concrete uses much less materials than reinforced concrete: savings can reach 40% of the overall mass longer spans, thinner and lighter parts allow a reduction in number of piles, height of buildings, consumption of energy in freight and handling, therefore co2 emissions. Low relaxation ensures that no noticeable loss of tension will occur in time, therefore a long lasting compressive force on concrete. Deviated tension is current in post-tensioned structures, stay-cables and even some prefabrication methods. By strict adherence to manufacturing processes and routine destructive tests, our products exceed standard requirements. Stress corrosion and hydrogen embrittlement are known to be a threat for high-tensile structural steels, especially in environments containing chlorides. We manufacture pc strand wire in a 3 or 7-strand configuration in both stress relieved and low relaxation grades. Diameters range from 3/8" (9.53 mm) to .600" (15.24 mm). Prestressing wire and strands are used in bridges, cryogenic storage, industrial, commercial and residential buildings where safety is critical.

Standard:astm a460 Capacity:2000ton/month Ccs wire is an extraordinary conductor that provides benefits that neither metal can provide alone. Because the bulk of the current travels along the wire's skin, it is ideally suited for high-frequency applications. Stranded dsa copper clad steel conductors are used for buried ground grid systems where a more economical alternative to copper conductors is desired. For utility applications, copper clad steel is used in substation and generation plant ground grids; grounding of metal fences; and in building and structure lightning protection systems. Copper clad steel is tough to cut and unlike copper conductors has virtually no scrap recovery value thus reducing the potential of theft or vandalism of the grounding wire. Copper clad steel wire (ccs) is a composite in which highly conductive, corrosion-resistant copper cladding is metallurgically bonded to a strong, durable steel core through a continuous, solid cladding process using pressure rolling for primary bonding. The copper cladding remains at constant thickness surrounding the steel and comprises a small minority of the overall wire diameter, but yields a conductivity substantially greater than that of unclad steel.
