Conventionally, Exhibition hall for steel construction buildings are constrained by the grid of internal columns and the heavily structural elements that visually dominate the entire space. Zhongda’s patented “Infinity-Span” steel structure system, through the ingenious internal stress-distributing method, removes the interior columns.
Without columns, the same building floor area can produce 25% more leasable space along with greater layout flexibility.
Serving as an invisible structural skeleton, Zhongda’s system is capable of supporting even the most daring façade designs, which can range from irregularly curved surfaces to fully transparent, porous curtain walls.
By engaging bolted spherical nodes and prefabricated components, the building can be expanded, or a part can be changed in the future, just like building blocks, without causing any structural damage.
Please be informed that the numbers here are only for your reference.
If you have other requirements, Zhongda engineers will perform a feasibility study based on your local conditions and project needs.






Leveraging digital twin technology, Zhongda takes a complicated infrastructure and simplifies it into a highly controlled industrial product.
Zhongda’s team collaborates with your architect through BIM to convert seductive architectural photos into structurally feasible solutions, thus the majority of potential construction conflicts (up to 99%) can be resolved before entering the construction phase.
The whole process of cutting, drilling, and welding is performed within a robot-controlled factory environment, where only high-precision, high-strength bolt connections and zero on-site welding are necessary.
When compared with traditional concrete buildings, the steel frame exhibition space made with Zhongda steel system can get weather-tight six to nine months earlier, and interiors can be fitted faster.
Besides giving away keys only, the handover is also merged with a digital structural model for full life-cycle operation and maintenance support.

Zhongda applies the same rigorous attention that is used in the construction of cross-sea bridges
right down to the tiniest detail of each square meter of an exhibition center's steel structure.
1. More than Two Decades of Heavy-Industry DNA.
Zhongda, established in 2002, is more than just a general contractor, but a heavy steel structure specialist. In a 120,000 m² production base, Zhongda has achieved industrial buildings with complexities that are ten times higher than a normal metal structure exhibition hall; thus, they have guaranteed solutions for large-span challenges.
2. Credentials in the Luban Award and the National Gold Award.
These accomplishments are not empty words, but documented outcomes.
With Grade-A steel structure contracting qualifications, Zhongda's projects have been awarded China's top construction honors. Your project gets landmark-level credibility right from the start.
3. Commitment to an Annual Capacity of 50,000 tons.
Exhibition centers, by nature, are enormous structures.
Zhongda's highly automated production lines have the capacity to produce up to 50,000 tons per year, thus even if there is a fluctuation in raw materials, you will have a constant supply and delivery on time.
4. A Strategic Partner for Central SOEs.
As a supplier to CSCEC and CREC, Zhongda's quality systems have been tested through the most rigorous audits.
In addition to the structure, you get a direct line to China’s top-tier infrastructure supply chain standards.



Q: Our design is very unique. Can Zhongda fully recreate the look?
A: Certainly. Zhongda is proficient in the manufacturing of complex as well as irregular structures.
In parametric modeling, Zhongda breaks down complex geometry into steel components that can be fabricated, thus allowing a 1:1 realization of your design concept.
Q: How does a steel structure fare in terms of fire protection and sound insulation?
A: Zhongda adopts insulated steel panel systems along with high-performance fire-resistant coatings and double layers of acoustic mineral wool.
Fire resistance and sound insulation levels match and even exceed international public building codes.
Q: Is Zhongda able to provide installation instructions worldwide?
A: Of course.
