GENERAL
We supply 7 wire pc strand with uncoated, galvanized and HDPE coated finishes. 7 ply pc wire strand is the most popularly used product in prestressing and post tension concrete structures. Uncoated pc strand fall into two types: low-relaxation and stress-relieved (normal- relaxation). Galvanized PC strand with corrosion resistant zinc coating layer is mainly used in mining and cable-stayed bridges construction.
Common sizes:
Structure:prestressed concrete 7-wire strand
Standard: ASTM416, BS5896, others
Nominal diameter:12.7 mm, 15.2mm, 21.8mm, 23.5mm prestressed concrete 7-wire strand
Application: Construction of bridge, highways, airports, sports venues and other infrastructure areas.
