Product Description
Steel strand is a steel product composed of multiple steel wires twisted together, which can be called PC Strand. The surface of carbon steel can be added with galvanized layer, zinc-aluminum alloy layer, aluminum clad, copper-plated layer, epoxy coated, etc. as required. In general, all kinds of steel strands should be delivered in coils. According to the agreement between the two parties, additional packaging such as moisture-proof paper, linen, and plastic woven cloth can be added.
Classification of steel strands
(1) Classification by use
Prestressed steel strands, galvanized steel strands (for electric power) and stainless steel strands, of which the prestressed steel strands are coated with anti-corrosion grease or paraffin and then wrapped with HDPE, called unbonded prestressed steel strands (unbonded steel strands) , Prestressed steel strands are also made of galvanized or galvanized aluminum alloy steel wire.
(2) Classification according to material properties
Steel strand, aluminum clad steel strand and stainless steel strand.
(3) Classification by structure
The prestressed steel strand can be divided into 7 wires, 2 wires, 3 wires and 19 wires according to the number of wires, and the most commonly used structure is 7 wires.
Galvanized steel strands and aluminum-clad steel strands for electric power are also divided into 2, 3, 7, 19, 37 and other structures according to the number of steel wires, and the most commonly used is the 7-wire structure.
(4) Classification by surface coating
It can be divided into (smooth) steel strands, galvanized steel strands, epoxy-coated steel strands, aluminum-clad steel strands, copper-coated steel strands, plastic-coated steel strands, etc.
