What are the weight limits for different types of outdoor benches, and how are they determined?

Outdoor benches come in various materials and designs, each with specific weight limits to ensure safety and longevity. Commercial and public benches, typically made of steel, concrete, or heavy-duty plastic, often support 500–1,000 lbs (227–454 kg) per bench. Residential benches, usually wooden or lightweight metal, may hold 250–400 lbs (113–181 kg). Weight limits are determined by material strength, structural design, and intended use, following industry standards like ASTM F2095 for commercial seating. Factors like weather resistance, load distribution, and anchoring also influence durability. Always check manufacturer specifications for exact ratings before installation.
