What steel gauge should a commercial stacking chair frame be?

Commercial stacking chair frame steel gauge directly correlates with durability and load capacity: 18-gauge steel (0.048" thick) is the minimum for light commercial use (occasional events, low daily frequency); 16-gauge (0.060" thick) is the standard for commercial hospitality, conference, and school environments; 14-gauge (0.075" thick) is the heavy-duty specification for high-frequency use, outdoor events, and bariatric applications. Thicker gauge steel adds weight (which may affect staff ergonomics when stacking and moving chairs) but significantly increases resistance to bending and denting under heavy loads.
