Brief introduction

1.Scored steel wire is a steel wire for prestressed reinforced concrete structures made of carbon steel wire (cold-drawn high-strength steel wire) for prestressed concrete structures that are scored by a special "scoring machine".

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.
