15.7mm unbonded PC Strand

The 15 7mm Unbonded PC Strand is a high-performance prestressed concrete tendon designed for use in modern construction projects. This product is specifically engineered to provide superior strength, durability, and flexibility, making it an ideal choice for a wide range of structural applications. The term "unbonded" refers to the fact that the individual wires within the strand are not permanently bonded together, allowing for greater movement and stress distribution under load. This feature enhances the overall performance and longevity of the structure it supports.

Key Characteristics of 15 7mm Unbonded PC Strand:

1. High-Tensile Strength: The 15 7mm unbonded PC strand is manufactured using high-quality steel wires that have been cold-drawn and heat-treated to achieve exceptional tensile strength. This ensures that the strand can withstand heavy loads and maintain its integrity over time.

2. Corrosion Resistance: The strand is coated with a protective layer that prevents rust and corrosion, even in harsh environmental conditions. This coating also helps to reduce friction between the wires, improving the strand's performance and extending its service life.

3. Flexibility and Ease of Installation: The unbonded design allows for easier handling and installation, as the individual wires can move independently. This makes the strand more adaptable to complex structural designs and reduces the risk of damage during the installation process.

4. Uniform Load Distribution: The 15 7mm unbonded PC strand is designed to distribute loads evenly across its length, minimizing stress concentrations and reducing the likelihood of failure. This feature is particularly important in structures subjected to dynamic or cyclic loading conditions.

5. Compliance with International Standards: The product meets or exceeds international standards for prestressed concrete tendons, ensuring its reliability and performance in various construction environments.

Detail Description of 15 7mm Unbonded PC Strand:

The 15 7mm unbonded PC strand consists of seven individual steel wires arranged in a specific pattern to maximize strength and performance. Each wire is carefully selected and processed to ensure uniformity and consistency in mechanical properties. The strand is then coated with a specialized lubricant and wrapped in a protective sheath to prevent moisture ingress and enhance its resistance to external elements.

One of the key advantages of the 15 7mm unbonded PC strand is its ability to accommodate movement and deformation without compromising structural integrity. This makes it particularly suitable for use in long-span bridges, high-rise buildings, and other large-scale construction projects where thermal expansion and contraction are significant factors. The strand's design also allows for post-tensioning, which is a common method used to reinforce concrete structures after they have been cast.
