Steel Wind Towers, Transmission Poles & Custom Steel Stacks
Since its establishment in 2008, Qingdao Yinglong Machinery Co., Ltd. has specialized in the custom manufacturing of non-standard building structural components.
The company has a comprehensive annual production capacity of 20,000 tons of carbon steel structures, 5,000 tons of stainless steel, and 3,000 tons of aluminum alloy. It strictly implements international standards such as AWS, EN, AS/NZS, and CSA to ensure stable delivery and long‑term service performance.
We specialize in the design and fabrication of tall steel structures such as transmission towers, wind towers, and industrial stacks, serving industries including power, renewable energy, chemicals, metallurgy, and paper manufacturing.
Our transmission towers include both angle steel towers and multi-sided tapered steel pole designs. Angle steel towers are hot-dip galvanized for corrosion resistance and long-term durability, while multi-sided steel poles are available with either hot-dip galvanizing or high-performance paint coatings to meet diverse environmental needs.
The steel structures we manufacture for wind towers are composed of tapered cylindrical segments, connected by high-strength flange bolts. These towers are engineered for stability and precision, providing reliable support for wind turbine nacelles and blade systems to ensure efficient high-altitude operation. For projects requiring custom-designed tall steel structures, we can develop fabrication solutions based on your engineering specifications and environmental conditions.

We also offer steel structure solutions for chimney systems in energy, chemical, metallurgy, and paper industries. With experience in large-scale welding, corrosion-resistant materials, and controlled fabrication processes, customized chimney structures can be developed to meet project-specific operational and environmental requirements.
