Air-Supported

Requires continuous inflation to maintain its shape, with a single, uninterrupted interior space (e.g., inflatable stadiums).

Air-Inflated

Supported by multiple inflatable tubular arches, with the membrane itself not bearing direct pressure (e.g., certain types of tents).

Air-Cushion

Composed of multiple inflatable cushions or units joined together (e.g., the exterior wall of the "Water Cube").

Pneumatic Structure

Ensure structural safety and stability

In the field of architectural membrane structures, pneumatic structures are building systems that rely on internal air pressure differentials to maintain shape, bear loads, and achieve structural stability. Simply put, air itself becomes the primary “structural material.”

Unlike traditional buildings that depend on rigid frameworks, the core principle of air-supported structures is “inflation.” Air is continuously supplied into one or more enclosed spaces using blowers, airlocks, or fans, creating an internal pressure slightly higher than the external atmospheric pressure (typically 0.1% to 0.5% above atmospheric pressure). This minimal positive pressure is sufficient to support the covering membrane, tensioning it into a stable curved surface capable of resisting external loads (such as wind and snow).

This type of air-supported structure fabric typically consists of three layers: a high-strength fabric substrate + PVC coating + PVDF surface treatment. For the application scenarios of air-inflated structures, we provide customizable air-supported structure fabric.
