Indented PC Wire, Two-sides, Three-sides, Four-side, Types, Features and Advantages. |
| Description: |
The pre-stressed steel wire is tensioned approx. 70 to 80% of the minimum specified breaking load of steel wire prior to casting of concrete. After initial setting of concrete, the pre-tensioned steel wire is released and the stress in the wire is induced in the concrete. This induced compressive stress will neutralize the tensile stress caused by the acting loads on the concrete member. In the case of pre-tensioning, it is important that adequate bond is created between the steel wire and concrete in order to transfer the desired compressive force from the steel wire to the concrete.
In order to improve the bond strength and achieve a consistently low transmission length, regular indentations of specified shape in the wire surface in either opposite or 120-degree planes or 90-degree planes were introduced. In the known art of indenting operation, it is possible only to make 2, 3 or 4-sided intermittent indentation on the surface of the wire. This indentation is normally carried out on a wire-drawing machine and is effected by pulling the wire through appropriate indenting rolls.
Advantages
- Improves the bond strength between pre-stressed steel wire and concrete
- Reduces the frictional losses between pre-stressed wire and concrete
- Increases the anchorage efficiency
- Maintains higher effective pre-stressing force in the structure
- Reduces the number of operations at the customer end

| Introduction: |
Ledning PC Wire Factory is one of the leading manufacturers of PC wire and PC strand. Our PC Wire & PC Strand equipment and technical know-how is among the finest in the industry. Our PC wire and PC Strand production process have strict quality inspection. So our product quality is guaranteed. All products must conform to industrial Standards or International Standards. Prestressed Concrete Steel Wire and strand have the advantages of higher fatigue, corrosion resistance and better performance at elevated temperature.
We offers major three types of PC wire including plain surface PC wire, spiral ribs PC wire and indented PC wire. Our PC wires are low relaxation and high tensile strength. They are widely used in reinforcement for concrete industry, such as large-span bridges on railway and highway, overhead crane beam, rock-soil anchoring Project, multi- storey industrial buildings, stadiums, coal mines and etc.
Our Factory also exports PC strand, Unbonded PC strand, Galvanized Steel Strand, spring steel wire and High Tensile Wire. PC strand confirm to the technical standards such as GB/T 5223, GB/T 5224, ASTM A-416, BS 5896, JIS G3536.
