Be sure to pay attention to the fire hazards associated with renting pavilions.

Pavilions are constructed using lightweight metal structures such as light steel frames and aluminum alloy profiles, combined with membrane fabrics or inflatable systems—essentially temporary tent-like structures—often employed for hosting special events and other activities.
The regulations regarding the setup of tent structures are not strict—any spacious, level area, such as grassy ground, can easily handle the task.
Due to the prefabricated structural components of the tent structures lacking sufficient load-bearing capacity and reliability, and being lightweight, there truly are no basic regulations in place.
Together, tent structures also have very low requirements for supporting facilities and equipment such as electrical and plumbing systems—most tents only demand satisfactory electrical load specifications, with no specific requirements for water supply or drainage.
Tent structures for rent—overall planning varies.
Some are only a few dozen square meters, but they indeed feature large spans and substantial total areas, with structures that even stack up to two or three stories high.
The theme-style interpretation fashion show at the World Expo features exhibition pavilions designed as performance stages for audience-oriented shows.
The pavilion was densely packed with staff, making it difficult to disperse.
The arrangement of performers and staff densely occupying the performance space creates a sense of interconnectedness, while the densely packed audience seated to watch the performance—along with seating arrangements, staircases within the venue, and other elements—becomes a factor that significantly complicates evacuation in emergency situations.
Examples of devastating fires that claimed numerous lives, such as the cinema fire in Karamay, Xinjiang, and the Dongdu Dance Hall fire in Luoyang, Henan, have taught us a painful lesson.
The material is highly flammable and has poor flame retardancy.
A tent structure is a temporary, simple space built over a yard.
The lightweight steel structure and aluminum alloy profile system used in the tent structures have a low fire-resistance rating.
The fire resistance rating for steel structures is typically 15 minutes, during which they quickly lose their load-bearing capacity, leading to structural collapse in the event of a fire.
Aluminum alloy profile prefabricated components have a lower fire resistance rating compared to steel structures, and they also lack fire-resistant coatings for maintenance and protection.
The membrane fabric of tents is often made from flammable or flame-retardant materials.
Today's applications typically use membrane fabrics composed of materials such as high-polyester fiber fabric membranes, polyester mesh, and waterproof Oxford cloth. After undergoing fire-retardant treatment, these materials can achieve a B1-level fire resistance rating.
Some membrane fabrics also possess fire hazards such as igniting molten droplets and sustained burning, which can easily lead to the spread of fires and compromise the structural integrity and safety of supporting elements.
The membrane fabric of the tent structure is also vulnerable to ignition sources from outsiders, and setting off fireworks—even harmless-looking ones—clearly poses a significant safety risk.
