5.Cooperated with Natinoal Railway for years.
we are a specialist concentrating on PC strand and PC wire supplying both China and the export market. PC strands are for prestressed concrete structure reinforced, such as large-span bridges on railway and highway, overhead crane beam, rock-soil anchoring project, multi-storey industrial buildings, stadiums, coal mines and etc.
The main characteristics of prestressed steel strand and relaxation properties of high strength is good, other than the upright when expanded. Common tensile strength rating of 1860 MPa, as well as 1720,1770,1960,2000,2100 MPa strength grade of the class.
Application:
1) Used in the upper plates of bridges
2) As cable for special bridges and for the maintenance of bridges
3) In construction, this product is used in concrete pillars and supports for the construction of buildings, domes for nuclear power plants and reinforcement of LNG concrete tanks.
4) It is also used as floor and roof reinforcement for sports stadiums.
5) It can be extensively used in construction materials for PC panels, high-pressure concrete water pipes, marine structures, towers and runways.
6) packing: Export anti-rust packing pallet
