Brief introduction

1.According to the diameter can be classified as: 4mm, 4.8mm, 5.0mm, 5.1mm, 6.0mm, 6.25mm, 7.0mm, 7.8mm, 8.0mm, 9.0mm, 9.5mm, 10.0mm, 11mm, 12mm, etc.

2.According to the strength level, it can be classified as: medium strength prestressed steel wire 800~1200MPa; High strength prestressed steel wire 1470MPa, 1570MPa, 1670MPa, 1770MPa and 1860MPa, etc.

3.According to the surface coating, it can be classified as: uncoated prestressed steel wire, epoxy resin prestressed steel wire and galvanized prestressed steel wire.

4.According to the surface morphology, it can be classified as: light circle prestressed steel wire, spiral ribbed or helix grooved prestressed steel wire (left or right rotation), crimped prestressed steel wire or indented prestressed steel wire (two-sided notch, three-sided notch, four-sided notch), etc.

5.According to the treatment process, it can be classified into: cold-drawn prestressed steel wire (no relaxation performance requirements) and low-relaxation prestressed steel wire.

APPLICATION & ACHIEVEMENT

PC strand and wire are mainly used to make large, medium and small concrete components of various shapes that are stretched successively, such as railways, highways, urban viaducts and long-span prefabricated components and earthquake-proof structures, etc.They can save steel and reduce the weight of components. It is an internationally recognized new building materials.

QUALITY INSPECTION

(1) Wire rod
Raw material for steel wire products is supplied by steel mill. Steel mils make wire rod by hot rolling process from bilet
(2) Surface treatment
Descaling wire rod removes rust and scales on the surface of wire. Surface coating wire rod facilitates drawing
(3) First Drawing
Descaled and surface coated wire rod is brought to 1st drawing machine to draw to required diameter and to give mechanical properties suitable for application.
(4) Stranding
Positioning the wires within the strands
(5) Stabilizing
Heat treatment process using high frequency relieves and removes stress.
