We are one of the leading manufacturers of PC strand. Our PC Strand equipment and technical know-how is among the finest in the industry. Our PC Strand production process has strict quality. And our PC strand has the advantages of higher fatigue, corrosion resistance and better performance at elevated temperature.
Common sizes: 9.3 mm. 9.6.12.7, 12.5, 12.9, 11.11, 11.3, 15.24 and 15.7 mm.
Raw Materials: High-carbon steel wire rods, SWRH 82B
Processing: Continuous drawing by means of big reduction of area, twist, stabilizing treatment
Features: High tensile strength, low relaxation, stable modulus of
elasticity, stress-relieved, firm connection with concrete, low
stress, stable construction, good combination with steel reinforced
concrete; saving material, reducing distortion and construction
weight, increasing the abrasion resistance, water resistance,
stiffness.
We offer PC Strand which confirm to the technical standards such as
GB/T 5223, GB/T 5224, ASTM A-416, BS 5896, JIS G3536 or the
standards agreed by both of the customers and us.
PC strand can also be supplied in various forms for pre- or
post-tensioning applications, with 7 wires
Inquiry please provide: Standard, Diameter, Mechanical property (especially tensile
strength), coil weight, Packing dimension, Quantity.
Packing: Export anti-rust packing with vapors corrosion inhibiting
technology and 3 coatings. There are two wooden pallets on the
bottom..
Application
Our PC strand is mainly used for the reinforcement of prestressed
concrete structures, such as large-span railway and road bridges,
major bridges, silos, buildings, dams, floor slabs, foundations,
large concrete vessels, atomic reactor buildings, stadiums, airport
hangers, pre-cast segments, crane beams, anchorages and
multi-storey industrial buildings etc.
Our PC strand is also used for the construction of highways, poles
and water towers in civil construction, and energy source sea
transportation, house buildings, water control projects, and rock
and earth anchoring components to increase the tensile force.
