Shanxi Factory Expansion Steel Structure Project

Project Background

A company in Shanxi planned to expand its existing factory building to meet new production needs. The client contacted Henan Jingtian Membrane Structure Engineering Co., Ltd. and expected Jingtian to provide a complete service covering design, steel fabrication, and on-site installation.

Compared with a new factory building, a factory expansion project is usually more difficult. The new structure must not only meet the requirements of the expanded production area, but also coordinate with the existing factory building in terms of building shape, structural load, connection method, and long-term safety.

The factory building is approximately 30 meters high. The project covers about 3,000 square meters of land area and has a building area of about 6,000 square meters. The construction period was about 2 months.

Site Investigation and Project Challenges

The client hoped that part of the expanded structure could make use of the existing factory building structure. This could help reduce repeated construction and control the overall project cost.

Before starting the design, Jingtian’s designers visited the site to inspect the existing factory structure.

The site investigation focused on:

Existing factory structure type;
Load-bearing condition of the original structure;
Connection conditions between the new and old structures;
Whether structural reinforcement was required;
Junction points between the existing and expanded factory areas;
Installation conditions for a 30-meter-high factory building.

After the site investigation, Jingtian prepared a reinforcement and expansion design solution based on the actual condition of the existing factory building.

Structural Design Solution

For this project, pipe truss columns were used as the main load-bearing columns.

Compared with some traditional heavy steel columns, pipe truss columns can meet structural requirements while helping optimize steel consumption. This solution helps control construction cost while maintaining structural stability.

Because the factory building is about 30 meters high, the design needed to consider vertical load-bearing capacity, overall stability, wind resistance, connection details, and installation difficulty.

Through the combination of pipe truss columns and the steel structure system, Jingtian completed the design, fabrication, and installation of the factory expansion structure.

Project Information

Design, Fabrication and Installation

Jingtian provided integrated service for this project, including site investigation, design planning, steel structure fabrication, and on-site installation.

During the design stage, Jingtian analyzed the existing factory structure and optimized the expansion solution.
During the fabrication stage, pipe truss columns and related steel components were fabricated according to the detailed drawings.
During the installation stage, the team arranged component delivery, lifting, connection, and alignment based on the conditions of the 30-meter-high factory building.

This integrated service helped reduce communication gaps between design, fabrication, and installation, improving project efficiency and quality control.

Project Highlights

The key challenge of this project was that it was not a simple new factory building. It was an expansion project based on an existing structure.

Jingtian inspected the existing factory, evaluated the structural conditions, and developed a practical reinforcement and expansion solution. This allowed the new factory area to connect properly with the original building.

The use of pipe truss columns helped ensure structural stability while controlling steel consumption and project cost. For high-rise steel structure factory expansion projects, this solution offers a balance between safety, economy, and constructability.

Completion Result

After completion, the client gained approximately 6,000 square meters of additional factory building area, meeting the company’s future production and operation needs.

The expanded structure was connected reasonably with the existing factory building. The overall structure is stable and practical, showing Jingtian’s experience in steel structure factory expansion, pipe truss structure application, site investigation, design, fabrication, and installation.

Jingtian Service

Henan Jingtian Membrane Structure Engineering Co., Ltd. provides customized services for steel structure factory buildings, factory expansion projects, pipe truss structures, industrial steel structures, warehouse canopies, and supporting steel structures.

For building expansion projects, Jingtian can provide practical steel structure solutions based on existing building conditions, project requirements, budget, and installation environment.

FAQ

1. Why is factory expansion more difficult than building a new factory?

Factory expansion must consider the existing building structure, load-bearing condition, connection between old and new structures, reinforcement requirements, and installation conditions. It requires more site investigation and structural judgment.

2. Why was site investigation necessary for this project?

The client hoped to partly use the existing factory structure. Jingtian’s designers needed to inspect the original structure on site to decide whether it could be used and whether reinforcement was required.

3. Are pipe truss columns suitable for high factory buildings?

Yes. Pipe truss columns can provide good structural stability and load-bearing performance. In some large or high steel structure projects, they can also help optimize steel usage and control cost.

4. How high is this factory building?

The factory building is about 30 meters high.

5. What is the project area?

The project covers about 3,000㎡ of land area and has a building area of about 6,000㎡.

6. How long was the construction period?

The construction period was about 2 months.

7. Can Jingtian provide full-service factory expansion solutions?

Yes. Jingtian can provide site investigation, design support, steel structure fabrication, transportation, and on-site installation according to project requirements.
