Brief introduction

1.Prestressed steel strand: mainly used for prestressed concrete structure, rock and soil anchoring and other purposes, according to the twisted structure is divided into 1*2, 1*3, 1*7 three categories. According to its stress relaxation performance, it is divided into two levels: grade I relaxation and class II relaxation.

2.According to its stress relaxation performance, it is divided into two levels: grade I relaxation and class II relaxation. It is mainly used to make large, medium and small prestressed concrete components of various structural shapes that are successively tensioned, such as: railways, highways, urban viaducts, hydropower dams, nuclear power plants and large-space large-span precast components and seismic structures.

3.It can save steel, improve the strength of components, reduce the weight of components, and is an internationally recognized new building material. Qingdao Ruisong Steel Cable Company can produce the following specifications of steel stranded products for you:

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.
