Our commitment to excellence is reflected in every aspect of our operations, from rigorous design parameters and advanced software utilization to stringent quality control measures and superior materials.

Strengths of Jielian Steel Tower Company

Adherence to Global Standards

Our design processes are grounded in both Chinese National Standards and American Standards, ensuring that our towers meet the highest regulatory requirements and performance expectations worldwide. Specifically, we follow:

• Chinese National Standards:
  • DL/T 5154-2002: Technical Regulation of Design for Tower and Pole Structures of Overhead Transmission Line
  • DL/T 5219-2005: Technical Regulation for Designing Foundation of Overhead Transmission Line
• American Standards:
  • ASCE 10-97-2000: Design of Latticed Steel Transmission Structures
  • ACI 318-02: Building Code Requirement for Structure Concrete

Advanced Design Software

We employ state-of-the-art design software such as PLS and MS Tower, SAP2000, AutoCAD, STW, TWsolid, and SLCAD to ensure precision and efficiency in our designs. These tools allow us to tailor our structures to the exact specifications and requirements of our clients, ensuring optimal performance and reliability.

Custom Design Loading

Our towers are designed to meet the specific loading requirements provided by clients worldwide, ensuring that they can withstand the unique environmental and operational conditions of each project.

Comprehensive Testing

To guarantee the robustness and durability of our towers, we offer load tests and destructive tests, which can be arranged through government authorities as needed. This thorough testing process ensures that our structures meet all safety and performance criteria.

Wide Range of Voltage Capacities

Our product range includes towers capable of supporting transmission lines from 33KV to 1000KV, catering to a broad spectrum of power transmission needs.

Superior Galvanization

We adhere to the highest galvanization standards—ISO 1461-2009 and ASTM A123—ensuring our towers are protected against corrosion and environmental wear, extending their lifespan and reducing maintenance costs.

High-Quality Materials

We use high-strength low alloy structural steels such as Q420B (equivalent to ASTM Gr60) and Q355B (equivalent to ASTM Gr50 or S355JR), as well as carbon structural steel like Q235B (equivalent to ASTM A36 or S235JR). This selection of high-quality materials ensures the structural integrity and longevity of our towers.

Robust Hardware

Our towers are assembled with bolts and nuts that meet ISO 898 grade 6.8 and 8.8 standards, ensuring secure and reliable connections.

Versatile Tower Types

We offer a diverse range of tower types including angular towers, tubular towers, guyed masts, and monopole towers, as well as specific configurations like suspension towers, tension towers, dead towers, and substation structures.

Long-Term Reliability

Our tower structures come with a 10-year warranty and a return period of 50 years, reflecting our confidence in the durability and performance of our products.

Strategic Location

Proximity to the world’s largest port provides us with logistical advantages for efficient and cost-effective sea transportation, ensuring timely delivery to our global clientele.

Rigorous Quality Control

We follow the ISO 9001 quality management system and implement strict quality control inspections for raw materials, prototype assembly tests, galvanization tests, and pre-shipment inspections. Our dedication to quality ensures that every product leaving our facility meets our high standards and those of our clients.

At Jielian Steel Tower Company, our comprehensive approach to design, rigorous testing, superior materials, and stringent quality control underscores our commitment to delivering exceptional transmission line steel towers and substation structures that stand the test of time.
