Product features and application
Long Service Life: Constructed from high-quality standard carbon steel certified by State Grid Corporation of China and China Southern Power Grid, our lattice steel towers are built with premium steel materials and corrosion-resistant surface treatment technologies, and have passed rigorous on-site and laboratory tests to deliver a long service life. The robust design ensures high reliability even under harsh operating conditions.
High Load-Bearing Capacity: The lattice design distributes loads evenly and efficiently, enabling the tower to support equipment at any position and withstand extreme conditions such as strong winds, heavy snowfalls and earthquakes.
Flexible Configuration: The height and load-bearing capacity of the lattice tower can be customized in line with customer requirements and network specifications.
Excellent Corrosion Resistance: Featuring hot-dip galvanized surface treatment, the tower enables long-term operation in harsh environments.
Easy Installation and Erection: Adopting standardized and modular design components, it shortens transportation time and reduces on-site assembly and erection duration.
Optimized Load Distribution and Network Stability: The lattice structure is optimized to evenly distribute weight and support heavy transmission lines as well as related components and equipment. Transmission performance remains stable even under extreme weather conditions.

Production details and product qualification
High-strength carbon structural steel is adopted as the main material, with each batch accompanied by an original factory material certificate. Before entering the production workshop, all raw materials undergo re-inspection of mechanical properties, spectral composition analysis and appearance dimension verification to eliminate unqualified materials from production. The entire production process is supervised by full-time quality inspectors, with full traceability for key processes. The workshop implements 5S management and lean production modes, and production equipment is regularly calibrated and maintained. All manual welding joints are subject to full visual inspection, followed by non-destructive testing in accordance with industrial standards to ensure structural safety and stability. Before delivery, finished products undergo dimensional recheck, galvanized coating thickness testing and structural load verification, and a factory inspection report is issued accordingly. Finished products are packaged with moisture-proof and anti-collision treatments for safe transportation.

Quality, Safety and Compliance Focused:
Our lattice steel towers are manufactured in strict compliance with mandatory national and industrial standards as well as project regulatory requirements. We have established a full-chain guarantee system for compliance, safety and quality covering raw material selection, production and finished product delivery. Key processes are subject to full traceability management, and all manual welds and critical joints undergo complete visual inspection and non-destructive testing. Prior to delivery, finished products undergo a full set of quality inspections including dimensional verification, galvanized coating thickness testing and structural load verification. We also hold a complete set of national standard certifications and third-party test reports, which fully ensure structural safety and stable performance of the products, and effectively meet the compliance access, safe construction and long-term durability demands of various engineering projects.
