● 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.
