About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Uses of Prestressed Steel Strands – Industry Trends and Best Practices

This article introduces the key models, material properties, and application areas of Tangshan Fushunde's prestressed concrete steel wire.

As the "invisible skeleton" of modern construction and bridge engineering, prestressed concrete steel wire's performance and selection are directly related to the safety and durability of major infrastructure.

Prestressed concrete steel strand is made from high-carbon SWRH82B steel wire. It undergoes continuous drawing and twisting with a high area reduction ratio and stabilization treatment. It boasts high tensile strength, low relaxation, stable elastic modulus, stress relief, and a strong bond with concrete. It complies with standards such as ASTM A416, BS 5896, and GB/T5224. It is primarily used in highways, bridges, water conservancy projects, and for anchoring and lifting tension members.

I. Core Models and Implementation Standards

National Standard: GB/T 5223 is the Chinese production standard.

International and foreign standards include European prEN 10138, British BS 5896, Australian AS/NZS 4672, and Japanese JIS G3536. This demonstrates that Tangshan Fushunde's products are fully aligned with international standards and are capable of competing in high-standard global competition.

II. Key Performance and Commonly Used ModelsThe core performance indicator of prestressing steel wire is its nominal tensile strength, which directly determines its load-bearing capacity. Tangshan Fushunde's prestressing steel wire strength models mainly include:

1470 MPa, 1570 MPa

1670 MPa, 1770 MPa

1860 MPa (currently one of the most widely used models)

Uses of Prestressed Steel Strand

1. Reinforcing Concrete Beams and Slabs

Prestressed steel strands are commonly used to reinforce concrete beams and slabs to improve their load-bearing capacity and seismic resistance. Prestressed steel strands generate compressive stress in concrete beams and slabs through tension, reducing cracking and deformation, and improving the strength and stability of the concrete.

2. Guiding Concrete Structures

Prestressed steel strands can also be used to guide concrete structures.

3. Reinforcing Concrete Bridge Piers and Bridge Deck

Prestressed steel strands are also widely used in bridge engineering. For example, adding prestressed steel strands to concrete piers and bridge decks can effectively improve the load-bearing capacity and durability of bridges, thereby ensuring their safety and reliability.

4. Reinforcing Concrete Foundations

Prestressed steel strands can also be used to reinforce concrete foundations. In some cases, concrete foundations may deform and crack due to environmental factors or other uncontrollable factors. Adding prestressed steel strands can reduce deformation and cracking in the foundation, thereby improving its load-bearing capacity and stability.
