ASTM A416 Prestressed steel strand
Exceptional High Strength – Prestressed steel strands are engineered to handle substantial tensile forces, with common tensile strength grades of 1860 MPa and options ranging up to 2100 MPa, making them ideal for heavy-duty structural applications.
Excellent Relaxation Performance – The stress-relieved (stabilized) design ensures the strands maintain their tension over time, providing long-term stability and reliability in prestressed concrete structures.
Straight and Uniform Shape – These strands retain a relatively straight form when unwound, facilitating easier handling, precise installation, and improved performance in construction projects.
High Yield Strength – The steel exhibits superior resistance to deformation under load, enhancing the durability and load-bearing capacity of concrete structures.
Prestressed Steel Strand
Prestressed steel strand, also known as PC strand, is a twisted cable composed of 2, 3, 7, or 19 high-strength steel wires that have undergone stress-relieving (stabilization). It is specifically designed for prestressed concrete and similar structural applications.
Key Features:
Prestressed steel strands are characterized by their high tensile strength, excellent relaxation properties, and the ability to remain relatively straight when unwound. The most common tensile strength grade is 1860 MPa, with additional grades available, including 1720, 1770, 1960, 2000, and 2100 MPa. These strands also exhibit high yield strength.

Classification:
Prestressed steel strands can be classified by:
Number of wires: 2-wire, 3-wire, 7-wire, and 19-wire strands.
Surface type: smooth (uncoated), notched, die-drawn (compact), galvanized, and epoxy-coated strands.
Other parameters: diameter, strength grade, standard, and raw material type.
Material Composition:
Prestressed steel strands are primarily made from cold-drawn high-carbon steel, often containing trace phosphide and lubricant residues. For ultra-high-strength applications (e.g., 2300 MPa), alloying elements like chromium are added. Galvanized strands may include higher silicon content. Coatings such as zinc, zinc-aluminum alloys, epoxy resin, grease, and high-density polyethylene sheaths are also applied to some products. Stainless steel, including high-strength duplex grades, can also be used for prestressed steel strands.
Prestressing Steel
Prestressing steel is a high-strength material primarily used in prestressed concrete construction. Its application significantly enhances the performance of concrete components under both static and dynamic loads.
Prestressing steel is produced as a long product, with surface shapes varying according to manufacturing standards. For instance, individual wires are designed following DIN EN 10138-1, while strand wires follow DIN EN 10138-3. Individual wires can reach strength levels up to 2000 N/mm² and are typically round in cross-section, though trapezoidal shapes—known as compact strands—are also available.
Steel strand is usually used for messenger wire, guy wire, core wire or strength member, etc. It can also be used as earth wire/ground wire for overhead power transmission, The barrier cable on both sides of the road or the structure cable in the building structure. Prestressed steel strands commonly used in prestressed steel strands are uncoated steel strands for prestressed concrete, and also galvanized. They are often used in bridges, buildings, water conservancy, energy, and geotechnical engineering. Unbonded steel strands or monostrand are often used in floor and foundation engineering，etc.
