Prestressed concrete with uncoated 7 strands of steel strand standard A416/A416M-05 82B prestressed concrete strand PC strand
Wire rod is a so-called long product which is formed into coils and used as a semi-finished product:
1. low carbon wire rod is used
for the production of welded wire mesh for the construction industry and for the production of drawn wire (raw, annealed and
coated).
2. Drawn wire, in turn, is made from medium and high carbon wire.
3. In addition to wire rod made of special steels for further processing in forging, drawing or pressing methods, it is also used as welding rod.

PC strand is a high carbon, seven-wire steel product used to impart compression forces into pre-cast structures. It's ideal for bridges, commercial buildings, parking decks, and other
slab-on-grade projects.
Galvanized PC strand is a steadfast solution for vehicle and pedestrian guard rail systems. This product has a high
strength-to-weight ratio making it less expensive to install
than precast panels.

The steel wire is made of high-quality carbon steel, which can achieve high strength after repeated cold drawing and heat treatment. Workplaces such as wet or open air environments can use steel ropes made of galvanized steel wire to enhance rust resistance. The steel wire rope is a flexible rope made of multiple or multiple strands of thin steel wires. The steel wire rope is twisted into strands by multiple layers of steel wires, and then takes the rope core as the center and is twisted into a helical rope by a certain number of strands. In material handling machinery, it is used for lifting, pulling, tensioning and bearing. The steel wire rope has high strength, light weight, stable operation, not easy to break suddenly and reliable operation. Structure: The steel wire rope is mainly constructed with steel wire and rope core. The steel wire rope plays the role of bearing the load, and its performance is mainly determined by the steel wire.
