Prestressed wire rope
Product overview:
Prestressed steel strand is a twisted steel cable composed of 2, 3, 7, or 19 high-strength steel wires. It can be divided into 7-wire, 2-wire, 3-wire, and 19 wire structures according to the number of steel wires, and the commonly used 7-wire structure. The commonly used prestressed steel strands in prestressed steel strands are uncoated low relaxation prestressed steel strands, as well as galvanized ones, which are commonly used in bridges, buildings, water conservancy, energy, and geotechnical engineering. Non bonded prestressed steel strands are commonly used in floor slabs, foundation engineering, etc.
Product Features:
The main characteristics of prestressed steel strands are high strength and good relaxation performance, and they are also relatively straight when unfolded. The common tensile strength grade is 1860 megapascals, and there are also strength grades such as 1720, 1770, 1960, 2000, and 2100 megapascals. This type of steel also has a high yield strength.
