Hybrid Steel Structure

The Hybrid Steel Structure is an optimized solution for substation structural design. It does not use a single structural form. Instead, it combines angle steel, steel pipe, and H-beam based on their respective load-bearing advantages. In high-stress areas, we use higher-capacity H-beams or thick-walled steel pipes. In low-stress areas, we use more economical angle steel. This achieves a balance between safety and cost. Qingdao Hongyuanfeng Power Equipment Co., Ltd. manufactures Hybrid Steel Structures with all components hot-dip galvanized. The zinc coating thickness is at least 86μm. This meets GB/T 2694‑2018 standards. Our R&D team uses 14 patents to perform precise mechanical calculations. We consider voltage levels, equipment layout, wind loads, and seismic conditions. This ensures every ton of steel is placed in the most effective position. The Hybrid Steel Structure is a smart choice for substation projects with tight budgets but high performance requirements.

Our Hybrid Steel Structures range from 5 meters to 20 meters in height. The specific height is determined by the substation electrical layout. Load capacity is calculated based on equipment weight, conductor pulling forces, and wind loads. Maximum wind speed capacity is 35 m/s, and earthquake resistance is grade 8. All components are bolted together. This requires no on-site welding and speeds up installation. Our production facility includes 8 fully automatic angle steel lines, 4 large laser cutting machines, and 6 sets of 1250A automatic submerged arc welders. This allows us to process angle steel, steel pipes, and H-beams simultaneously. Monthly capacity is sufficient to meet multiple material requirements for Hybrid Structures.

Qingdao Hongyuanfeng Power Equipment Co., Ltd. started in 2019. Our factory is located in Beiguan Industrial Park, Jiaozhou, Qingdao. The facility covers 151 mu and employs about 120 workers. We hold 14 patents, 2 registered trademarks, and 3 administrative licenses. We have passed quality management, environmental management, and occupational health and safety certifications. We are recognized as a "High-tech Enterprise" and a "Qingdao Specialized and Sophisticated SME". Our certified quality inspectors monitor every batch from raw material arrival to finished galvanized product. We strictly follow GB/T 2694‑2018 throughout production. We perform 100% inspection before packing and accept third-party inspections. Our Hybrid Steel Structures have been used in many 220kV and 500kV substation projects.

In projects like the Suzhou Yuexi 500kV Substation and Xishan 500kV Substation, our Hybrid Steel Structures effectively reduced project costs while maintaining structural safety. The design units and construction companies highly recognized our approach. We also supplied framework products for the West‑to‑East power transmission project, one of China's national key projects. Our Hybrid Steel Structures solve the problem of balancing structural strength and budget in complex substations. We produce according to customer technical drawings with a minimum order of 10 tons. Custom sample development for large items takes 7‑10 days.

Hongyuanfeng provides full service. Before the sale, our technical team connects with customers. We study substation conditions, provide planning, and handle drawing discussions. We provide reasonable quotes and support tender technical queries. During production, we share real‑time progress updates. We coordinate loading, shipping, and logistics. We also communicate on‑site installation conditions in advance. After the sale, we offer a 2‑year warranty. We can send technicians to guide installation and solve technical issues. We also conduct regular follow‑up visits.
