Write a short note on prestressing steel wires?

Prestressing steel wires are the strands of reinforcement that is used in the production of reinforced prestressed concrete elements that should have high tensile strength.

There are many types of prestressing steel wires classified on different parameters, such as for diameter it can be categorized from 4mm to 12mm and so on, for intensity level it can be categorized from 1470Mpa to 1860Mpa, for surface coating it is categorized as prestressed epoxy coated steel wire, galvanized prestressed steel wire, no coating prestressed steel wire, for surface morphology it is categorized as spiral rib, the pressure wave, prestressed steel wire, nicks, light round prestressed steel wire, for treatment process it is categorized as low relaxation prestressed steel wire and cool drawn prestressing steel wire.

There are many applications of prestressing steel wires such as concrete strand is used for prestressed concrete structure reinforced, like overhead crane beams, multi-storey industrial buildings, mines, large-span bridges on railway and highways, stadiums, rock-soil anchoring projects, etc.

PE coated steel strand for prestressed concrete is suitable for a large loads of precast beams and other special structures, large-span and large bays cast-in-place concrete floor.
