What materials are folding chair legs made from?

Commercial folding chair legs are most commonly made from: steel (16–18 gauge powder-coated — the standard for heavy-duty commercial use, rated 300–500 lbs); aluminum (lighter than steel, corrosion-resistant, preferred for outdoor or frequent-transport applications); and high-density polyethylene (HDPE) for all-plastic folding chairs (lower cost, lighter, outdoor-appropriate). Steel legs are the most durable for high-frequency commercial use; aluminum is preferred for outdoor event companies; HDPE is appropriate for casual or outdoor-only use. Leg thickness matters — thicker gauge legs are more resistant to bending under load.
