(1) Classification by use
Prestressed steel strand, galvanized steel strand (for power) and stainless steel strand. Prestressed steel strand coated with anti-corrosion grease or paraffin and then wrapped with HDPE is called unbonded prestressed steel strand. Prestressed steel strand is also made of galvanized or galvanized aluminum alloy steel wire.
According to the number of steel wires in a steel strand, it can be divided into: 2-wire steel strand, 3-wire steel strand, 7-wire steel strand and 19-wire steel strand.
According to the surface morphology, it can be divided into: smooth steel strand (uncoated), notched steel strand, die-drawn steel strand (compact), galvanized prestressed steel strand, epoxy resin coated prestressed steel strand, etc.
It can also be classified according to diameter, strength level, standard or raw material.

The main characteristics of prestressed steel strand are high strength and good relaxation performance, and it is relatively straight when unfolded. The common tensile strength grade is 1860 MPa, and there are strength grades such as 1720, 1770, 1960, 2000, 2160, 2230, and 2360 MPa. The yield strength of this steel is also very high.

(2) Classification by material properties
Steel strand, aluminum-clad steel strand and stainless steel strand.

(3) Classification by structure
Prestressed steel strand can be divided into 7-wire, 2-wire, 3-wire and 19-wire structures according to the number of steel wires. The most commonly used is the 7-wire structure.
Galvanized steel strand and aluminum-clad steel strand for power are also divided into 2, 3, 7, 19, 37 and other structures according to the number of steel wires. The most commonly used is the 7-wire structure.

(4) Classification by surface coating layer
It can be divided into (smooth) steel strand, galvanized steel strand, epoxy-coated steel strand, aluminum-clad steel strand, copper-coated steel strand, plastic-coated steel strand, etc.
