When selecting benches for public spaces, the cost difference between metal and recycled plastic is significant, but it's only part of the story. Initially, metal benches, particularly those made from cast iron or steel, often have a lower upfront purchase price. Basic models can start at a few hundred dollars. Recycled plastic benches, made from post-consumer plastics like milk jugs, typically command a higher initial investment, sometimes 20-50% more than comparable metal ones.
However, the true cost unfolds over years of use. Metal benches require ongoing maintenance: they need regular painting or powder-coating to prevent rust, especially in wet climates. This adds labor and material costs every few years. Recycled plastic benches, while pricier upfront, require virtually no maintenance. They won't rust, splinter, or need painting. Their color is molded throughout the material, so scratches are less noticeable.
Durability also impacts cost-effectiveness. High-quality recycled plastic is impervious to moisture, insects, and rot. A well-made plastic bench can last decades with minimal upkeep. Metal is incredibly strong but can become pitted or corroded without care, potentially shortening its lifespan in harsh environments.
For long-term value in high-traffic public parks, many project managers find the higher initial cost of recycled plastic is offset by zero maintenance budgets. For a formal, historic setting where the classic look of wrought iron is essential, metal may be the chosen value despite its upkeep. Ultimately, the "cheaper" bench depends on your timeline: metal often wins on day-one price, while recycled plastic frequently provides greater long-term savings and sustainability.
