PC Anchor Cable Steel Strand
1. High strength: PC steel strand has excellent strength and can withstand large tensile force, making it highly reliable and safe in engineering construction.
2. Corrosion resistance: PC steel strand is specially treated to have good corrosion resistance, which can resist the erosion of chemical substances and prolong its service life.
3. Flexibility: As PC strand adopts multi-stranded structure, it has good flexibility and bendability, which is easy for construction and installation.
4. Cost saving: PC strand has a longer service life and less maintenance cost, which can reduce the overall cost of construction.
5. Environmental protection: PC steel strand material can be recycled and reused, in line with environmental requirements, less impact on the environment.
PC Steel Wire：
PC steel wire is an important material for high-strength prestressed concrete components, mainly used for prestressing reinforcement of concrete structures. It consists of high-quality carbon steel wire, which is professionally processed and has high strength, good flexibility and corrosion resistance.PC steel wire is widely used in the construction of bridges, tunnels, subways, high-rise buildings, etc., which can effectively enhance the tensile properties of concrete members and prolong their service life. The use of PC wire prestressing technology can improve the quality of the project, reduce the amount of material, is a reliable and economical method of prestressing reinforcement.

Uses
Cold-drawn steel wires for prestressed concrete strands: Used for the reinforcement of prestressed concrete structures, such as large-span bridges on railroads and highways, bridge crane girders, geotechnical anchoring works, multi-storey industrial buildings, sports stadiums, coal mines and so on.
PC wire, galvanized, ASTM A416-10, 270k, low relaxation, for bridge suspension and stay cables.
PE coated/coated strands: for large spans and bays of cast-in-place concrete floor slabs, large loaded precast girders and other specialized structures.
Steel Strand Structural Characteristics:
Anchor the strand through a weak rock formation or sliding surface by anchoring one end in a hard rock formation and then applying tension at the other free end to create pressure on the rock formation, thus fixing the unstable rock for anchoring.
Usage:
According to the diameter and length of the anchor cable, drill appropriate holes at the corresponding position, clean the debris in the holes, then pour in the appropriate amount of resin anchoring agent (the specific type and dosage is specified by the design), and push the resin anchoring agent to the bottom of the holes by using the anchor cable. Next, connect the end of the anchor cable to the connector of the anchor drilling rig, start the drilling rig, and mix the resin anchoring agent according to the specified time. After the resin has cured, install the pallets and anchors, and use the tensioner to stretch the anchor cable to a predetermined preload.
