Shandong prestressed spiral ribbed steel wire


Category:

Sprial wire

Introduction MAINFEATURE parameter table Prestressed spiral rib steel wire: The product is characterized by the surface of the steel wire through spiral deformation and drawing to form 3 to 6 raised spiral ribs, which increases the adhesion with the concrete, thereby improving the performance of the prestressed concrete product. Since 1997, spiral ribbed prestressed concrete steel wire has completely replaced the scored prestressed concrete steel wire and has been applied to prestressed concrete poles, prestressed concrete hollow floor slabs, prestressed concrete sleepers, high-speed railway prestressed concrete sleeper plates, prestressed concrete water pipelines and other components.

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.
