Galvanized Steel Strand 1 × 7 Strands PC Wire

1 × 7 Strands Of PC Steel Wire

“1 × 7” is a wire rope structure in which ‘1’ stands for a single wire and ‘7’ means that the wire is surrounded by six thinner wires. Wire ropes of this structure usually have high strength and durability, and are suitable for lifting, pulling, fixing and other fields of engineering.

As for “PC wire”, it usually refers to steel strands used in prestressed concrete members to increase the strength and stability of the members, and is generally made of high-strength cold-drawn steel wires that are pre-stressed for use in a variety of heavy structural projects.

Therefore, “1 × 7 strand PC wire” can be interpreted as a structure consisting of one thick steel wire and seven thin steel wires, which is used in prestressed concrete members and is characterized by high strength and stability.

Product Description:

Mining Anchor Cable in Coal Mine or Other Mines In the support project of mine tunnel, the form and parameters of the conventionally designed anchor support may not be able to support effectively, leading to the collapse of the overall support structure, which brings serious consequences. To solve this problem, better results can be obtained by using steel articulated wires as anchor cables. Since the length of the steel reamer has no limitation and the anchor loop can be anchored to the hard top plate, and its high strength level can provide a large prestressing force, which makes the top plate in the lower part of the anchor group section form a uniform and rigid structure, thus providing a better support effect.

Through the use of steel hinged wire anchors, the mine roadway can be better reinforced, the support effect can be improved, and the risk of accidents can be reduced. This kind of support method, which provides larger prestress and forms a uniform rigid roof plate, has important application significance in mining engineering.
