What are the load-bearing differences between thick and thin polypropylene benches?

Polypropylene benches are popular for their durability, weather resistance, and versatility in outdoor settings. However, their load-bearing capacity varies significantly depending on thickness. Thick polypropylene benches (typically 1.5 inches or more) offer superior strength, supporting heavier weights (up to 500 lbs or more) with minimal flexing. They are ideal for high-traffic areas or commercial use. Thin polypropylene benches (under 1 inch) are lighter and more economical but have lower load limits (around 200-300 lbs), making them better suited for residential or light-use spaces. Thicker benches also resist warping and cracking over time, while thinner ones may sag under prolonged stress. When choosing, consider intended use, weight requirements, and long-term durability needs.
