Prestressed Steel Strand Description

● Steel Wire for Prestressed Concrete:
The product is mainly used to produce prestressed concrete components of various structural shapes using various tensioning techniques. In the construction of large-scale railways, highway bridges, roof trusses, crane beams, industrial and civil prefabricated panels, wall panels, prestressed concrete TV towers, nuclear power plants, and other engineering projects. Produce two surface forms: smooth and spiral ribs. American standards ASTMA416, ASTMA421, British standard BS5896, Japanese standard JISG3536, international standard ISO6934, European standard EN10138 

● Steel Strand for Prestressed Concrete :
This product is mainly used for reinforcing prestressed concrete structures. Such as large-span railway and highway bridges, crane beams, geotechnical anchoring engineering, multi-layer industrial factories, coal mines, sports venues, etc. Main executive standard: ASTM A416

● Unbonded Steel Strand for Prestressed Concrete: 
Post tensioned unbonded prestressed steel strands are used for cast-in-place floor slabs, prefabricated beams with large loads, and other specially designed structures in large-span and large-span buildings. It has the characteristics of no need for reserved holes, no need for grouting, simple construction, material saving, and easy bending.
