Project Overview:
The Qingdao Yiheshun Heavy Industrial Steel Factory is a large span steel structure factory building designed for heavy-duty industrial manufacturing. Located in Pingdu, Qingdao, the project occupies approximately 46 mu and is planned as a high-standard industrial base with strong load capacity and flexible space organization.
The factory adopts advanced structural steel framing systems combined with structural steel frame construction, making it suitable for heavy machinery installation, overhead crane systems, and long-term high-intensity industrial operation. The large span layout significantly reduces interior columns, maximizing usable production space and improving logistics efficiency within the workshop.
The roof structure is engineered with structural steel roof framing and reinforced metal stud roof framing, providing excellent structural stability, wind resistance, and durability under heavy industrial conditions. This design supports large span requirements while maintaining cost efficiency and fast construction schedules.
As a representative heavy industrial steel structure project, this factory demonstrates the advantages of structural steel framing systems in large span factory buildings, offering a reliable and scalable solution for heavy manufacturing, equipment assembly, and industrial production facilities.

Project Overview
Client Needs & Background
Qingdao Yiheshun Electric Co., Ltd., a rapidly expanding electrical appliance manufacturer, initiated the construction of a new high-standard, large-span production workshop to meet growing production demands and modernize its manufacturing processes. Covering 46 acres, the project broke ground in October 2020. The primary objectives were to maximize interior space, ensure efficient construction timelines, and guarantee long-term operational economy and flexibility, all while maintaining absolute structural safety and reliability.

Clear force transmission path, safe and reliable. Forms the basis for rapid modular construction. |
Technical Details & Advantages
Efficient Prefabrication & Installation: All steel components were cut, drilled, and coated in a digitally controlled factory environment. The on-site work primarily involved "assembly." This structural steel frame construction model reduced the on-site erection time for Workshop No. 4's primary frame by approximately 40%.
Superior Space & Economic Efficiency: The optimized structural steel framing design reduced steel tonnage while meeting all load requirements, lowering the client's overall project cost. The large column-free space allows production line layouts to be flexibly adjusted in response to evolving needs.
Sustainability: Steel is 100% recyclable, offering significant environmental benefits throughout the building's lifecycle. Precise manufacturing also minimized on-site construction waste, aligning with green building principles.
Project Outcome Summary
The successful completion of Qingdao Yiheshun's Workshop No. 4 stands as a testament to the effective application of modern structural steel framing systems in industrial construction. It not only rapidly addressed the client's urgent need for production space but also, with its exceptional flexibility, economy, and durability, provides a solid foundation for Yiheshun Electric's long-term growth. This project demonstrates that choosing a professional structural steel frame construction solution is a strategic decision for achieving efficient, high-quality industrial building projects.
