In 2026, a customer in Europe approached HAFE with a clear requirement: they needed a large, professional-grade temporary structure that could be deployed quickly, provide generous clear-span interior space, and support repeated use across event, exhibition, and operational scenarios.
The customer required a covered area of approximately 1,500 m², with enough internal height for visitor circulation, equipment layout, lighting, ventilation, and branded presentation. Traditional temporary steel structures were considered, but the installation cycle, transport volume, and foundation requirements made them less suitable for the project timeline.
HAFE proposed a 30*50 m Modular Air-Rib Inflatable Building, designed to deliver a spacious, column-free temporary venue with fast deployment, modular transport, smart pressure control, and weather-ready performance.
The final solution helped the customer create a large-scale, reusable covered space for events, exhibitions, temporary operations, and equipment protection, while maintaining flexibility for future relocation and reconfiguration.
The customer was not simply looking for a temporary shelter. They needed a reliable venue solution that could meet commercial, operational, and safety requirements.
Their key priorities included:
- A large 30 m clear-span interior without center columns
- Around 1,500 m² of usable covered space
- Faster installation compared with conventional steel structures
- Modular design for easier transport, storage, and future reuse
- Adequate height for lighting, ventilation, people flow, and equipment movement
- Weather resistance for wind, rain, and possible snow conditions
- Safe access planning, including side doors and emergency exits
- HVAC and fresh air interfaces for better indoor comfort
- Pressure monitoring and backup inflation options for operational stability
- Technical documentation for internal review and project approval
- Branding areas for event or commercial presentation
HAFE developed a project-ready air-rib building solution based on the customer’s site layout, intended use, access requirements, and local environmental conditions.
The proposed structure used a modular air-rib system, with 4–5 connected building modules. This allowed the entire structure to be packed, transported, installed, dismantled, and maintained more efficiently than a conventional heavy-frame solution.
The building was designed with a large main entrance for equipment access, multiple side personnel doors for daily operation and emergency evacuation, reserved HVAC and fresh air interfaces, lighting hanging points, drainage planning, anchoring guidance, and optional logo areas for brand visibility.
To support safe operation, HAFE also recommended a multi-air-chamber structure, automatic pressure control, pressure sensors, relief valves, alarm systems, and main/backup blower configuration.

After reviewing the proposal, the customer appreciated that the HAFE solution addressed both the visible space requirement and the practical details behind daily operation.
They highlighted three main advantages: the large column-free interior, the shorter deployment timeline, and the ability to integrate doors, HVAC interfaces, lighting points, drainage, anchoring, and pressure control into one coordinated structure.
The modular air-rib design also gave the customer more confidence for future use. Instead of investing in a one-time temporary setup, they received a reusable building system that could be transported, reinstalled, and adapted to different project sites.
“The HAFE solution gave us the scale of a temporary hall, but with much better flexibility for transport, installation, and future reuse. The clear interior space and integrated technical planning were exactly what we needed for this project."
| Comparison Item | HAFE Modular Air-Rib Inflatable Building | Traditional Temporary Steel Structure | Conventional Tent Structure |
|---|---|---|---|
| Installation Speed | Fast deployment with modular inflatable system | Longer installation cycle | Relatively fast, depending on size |
| Transport Efficiency | Compact packing and modular transport | Requires more heavy components and transport capacity | Moderate |
| Interior Space | Large column-free clear span | Can be clear span but usually requires heavier structure | May require more supporting components |
| Foundation Requirement | Anchoring system based on site conditions | Often requires stronger foundation or ground preparation | Usually lighter anchoring |
| Reusability | Designed for repeated installation, relocation, and maintenance | Reusable but less flexible to move | Reusable, usually lighter-duty |
| Safety System | Multi-air-chamber design, pressure monitoring, backup blower options | Structurally stable but labor-intensive | Depends heavily on frame, fabric, and anchoring |
| Weather Resistance | Configurable wind, snow, drainage, and waterproofing design | Strong when engineered properly | More limited for large or harsh environments |
