Details

Long-span steel-membrane structure

This steel-membrane structure uses high-strength steel as the main framework. With sophisticated grid and pipe truss design, it achieves ultra-long spans up to 100 meters for stable and solid performance. The steel frame bears major loads, while the tough smooth membrane reduces wind resistance effectively. It resists strong winds and typhoons, and meets snow & wind load standards for cold and snowy regions.

Pristine Steel-Membrane Structure

The framework is covered with premium PVDF membrane, which delivers excellent waterproof, UV resistance, and flame-retardant properties. It remains impervious to wind and rain, while its fire-resistant nature ensures it self-extinguishes quickly when the flame source is removed. Thanks to its outstanding hydrophobic and self-cleaning capabilities, dust does not adhere easily and is washed away by rain. This keeps the steel membrane structure looking perpetually new, clean, and visually appealing.

Fully covered grandstand with steel membrane

All components are prefabricated in factory under standardized procedures for on-site assembly, significantly reducing construction time compared to traditional buildings of the same scale. The lightweight steel-membrane structure places lower demands on the foundation and offers great flexibility. It is perfectly suited for roofing applications such as grandstands, event areas, open-type storage centers, and parking lots, striking an ideal balance between construction efficiency and practicality.

Other Advantages

Landmark steel-membrane structure

High-translucency membrane for optimal natural lighting; heat-reflective features minimize heat accumulation, delivering an energy-saving and comfortable environment.

Nighttime light transmission creates a soft diffused glow, balancing illumination with visual experience to establish a highly recognizable landmark.

Application Scenarios

Schools

Construct stadium stands and natural lighting canopies to provide a safe, healthy campus environment.

Scenic Areas

Easily install infrastructure like rest stations without being limited by the inability to build complex foundations in scenic spots.

Enterprises

Rapidly build cost-effective, large-span semi-open spaces to help enhance corporate image.

Municipal Construction

Quickly complete urban coverage projects, minimizing the impact on traffic and residents' daily lives.

Frequently Asked Questions

Q1: Are steel-membrane structures relocatable?

A1: Yes. Their lightweight and modular design allows them to be disassembled and reassembled like "building blocks." However, this requires ensuring that the new site's foundation dimensions, anchor points, and climate conditions match the original design.

Q2: Can steel-membrane structures withstand hail and rainstorms?

A2: Generally, yes. They can easily handle rainstorms thanks to their scientifically designed curved drainage systems. As for hail, safety is ensured by using double-layer buffering or high-strength composite membrane materials.

Q3: What should be done if the membrane material gets damaged?

A3: Small areas of damage can be quickly resolved with on-site heat welding repairs; larger damaged sections require replacing the specific membrane unit.

Q4: What is the average lifespan of a steel-membrane structure?

A4: With regular and proper maintenance, the structure is designed to last over 25 years, providing long-term structural integrity and aesthetics.

Q5: How long does the on-site construction process take?

A5: Because all components are pre-engineered and fabricated in the factory, the on-site assembly is highly efficient, allowing the structure to be ready for use in just 7 to 20 days.

Q6: What are the fire safety ratings for the membrane materials?

A6: The premium PVDF coated polyester fabric features a Class B1 fire rating. It is highly flame-retardant and will self-extinguish quickly once the source of the flame is removed.
