PC Strand
Wire Steel Strand Construction Prestressing PC Strand Prestressing
Product Description
It can also be classified according to diameter, strength level, standard or raw material.
Specifications of high-strength prestressed steel strands
The specifications on the Chinese market are 15.2mm in diameter, less 12.7mm and 15.7mm, and thicker steel strands are used for mine support.
Material of high-strength prestressed steel strands
Prestressed steel strands are mainly made of cold-drawn high-carbon steel, with trace phosphide and lubricant residues on the surface.
When the strength is particularly high (such as 2300 MPa), alloy elements such as chromium need to be added, and galvanized high-strength products can increase the silicon content.
Some prestressed steel strands made of carbon steel have coating materials on their surface, such as zinc, zinc-aluminum alloy, epoxy resin, grease and high-density polyethylene sheath.
Stainless steel can also be used to make prestressed steel strands, using high-strength duplex stainless steel.
