Prestressed Steel Strand for Energy Purpose
Prestressed steel strands for energy purposes are made of high carbon steel wire rods SWRS82B and SWRH82B-2 and have the characteristics of high tensile strength, low relaxation, and steady modulus of elasticity, relieved stress, and high adhesion with concrete through continuous drawing with large deduction stranding and stabilization treatment to meet the EN10138, BS 5896, and GB/T5224 standards. Such steel strands are primarily used in wind turbines, liquefied natural gas (LNG) tanks, and nuclear reactor shields. Pre-stressed steel strands are the most ideal material for the main reinforcement bars of nuclear reactor shields because of their strengths such as high bearing capacity, low relaxation, great flexibility, and ease in binding. Such steel strands are used in construction of (LNG) tanks for their properties of good tensile strength and low-temperature static load anchoring. They are primarily used as the external cables on concrete wind turbine towers for their strengths in design flexibility and rapid construction to provide prefabrication, standardization, and preassembly solutions to concrete structures.
