High Tensile Prestressed PC Steel Wire for Concrete
Intensity:1470Mpa-1770Mpa.
Standard: ASTM,BS,DIN,GB.
Wire Diameter:4.00mm-12.00mm.
According to diameter and can be categorized as: 4mm, 4.8mm, 5.0mm, 5.1mm,
6.0mm, 6.35mm, 7.0mm, 7.8mm, 8.0mm, 9.0mm, 10.0mm, 11mm, 12mm and
so on.
According to intensity level can be classified as: 1470MPa, 1570MPa, 1670MPa,
1770MPa and 1860MPa.
In accordance with the surface coating, high tensile PC steel wire can be classified
as: no coating prestressed steel wire, prestressed epoxy coated steel wire and
galvanized prestressed steel wire.
In accordance with the surface morphology can be classified as: light round
prestressed steel wire, spiral rib (spiral ribbed or helix grooved) prestressed steel
wire, the pressure wave (crimped) prestressed steel wire or nicks (indented)
prestressed steel wire and so on.
In accordance with treatment process can be categorized as follows: cold-drawn
prestressing steel wire (no slack performance requirements) and low relaxation
prestressed steel wire.
Uses:
-Steel strand for prestressed concrete strand: use of prestressed concrete
structure reinforced, such as large-span bridges on railway and highway,
overhead crane beam,rock-soil anchoring project, multi-storey industrial
buildings, stadiums, oal mines and etc.
-PE coated steel strand for prestressed concrete: Suitable for large-span and
large bays cast-in-place concrete floor, large load of precast beams and other
special structure.
-and many other steel wire and steel strand products
