Product Description

²Prestressed Concrete Strand Description:

Prestressed concrete strand(PC Strand). The products are mainly for the use of prestressed concrete structures reinforced. Such as large-span bridges on railways and highways, overhead crane beams, rock-soil anchoring Projects, multi-story industrial buildings, stadiums, coal mines, etc. Product's standards: GB/T5224, ASTMA416, BS5896, JISG3536, ISO6934, EN10138 or other special required standards.

1x7 prestressed steel strand, low relaxation pre-stressed steel strand is composed of 7 wires, it has the features of high tensile strength and very low relaxation, which make it could replace traditional deformed steel bar well, and save a lot of steel material. Meanwhile, it makes long-span concrete construction possible.

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, and stiffness.

PC Strand Prestressed Concrete Steel Strand

Prestressed Concrete Strand Feature:

 

1. The PC steel strands we provide comply with technical standards such as GB/T 5223, GB/T 5224, ASTM A-416, BS 5896, JIS G3536, or standards mutually agreed upon by the customer and us.

2. PC Strands are also available in various forms for pre-tensioning or post-tensioning applications in plain or galvanized materials ranging from 3 wires, 7 wires, 19 wires, and compact constructions.

3. Standard: GB/T5224, ASTMA416, BS5896, JISG3536, ISO6934 & EN10138

Raw Material

Our raw material is high-carbon wire rods SWRH82B and SWRH77B. We mainly purchase the most excellent wire rods from the famous steel group in China.

PC Strand Prestressed Concrete Steel Strand

Production Process 

Raw materials (inspection wire) → Surface treatment → First drawing → Steel strand (9 times of drawing) → Stabilization treatment → Anti-rust coiling → Packaging

PC Strand Prestressed Concrete Steel Strand

Inspection:

Both ends of one pc strand coil shall be inspected through stress relaxation test,tension test, hydraulic universal test, 

bending test and boroscope test, etc.
