Steel strand consists of prestressed steel strand, the unbonded steel strand, galvanized steel strand, etc. and different steel strands have different performance characteristics, please refer to the reference documents.
The most commonly used steel strand for galvanized steel strand and prestressed steel strand, commonly used prestressed strand diameter in the 9.53mm-17.8mm range, there are a small amount of a more coarse diameter of the steel strand. The steel wire in each prestressed strand is generally 7, there are 2, 3 and 19, steel wire can have metal or non-metallic anti-corrosion layer. The HDPE strand (unbonded), which is coated with anticorrosive oil or paraffin, is called the non bonding prestressed strand (steel).
The manufacturing process is divided into single strand manufacturing and manufacturing, made of monofilament (cold) when drawing technology, according to the
Products of different materials can be of high carbon steel wire rod, stainless steel wire rods or low carbon steel wire, galvanized if needed should be on a single filament of plating or hot plating processing. Wire manufacturing process using wire machine will be a plurality of wire twisted synthetic products, prestressed steel strand also need after forming continuous stabilization processing and final products generally received in spool (reel) or by no scroll reel-less completion.
