That's an excellent question, and one we hear often from planners and property managers. The short answer is that cast iron benches typically have a higher initial purchase price than aluminum benches. However, the true cost involves more than just the sticker price; it's about long-term value, durability, and maintenance.
Let's break it down. Aluminum park benches are generally less expensive upfront. The material itself is lighter and easier to manufacture into complex shapes, which often translates to lower production and shipping costs. You can find many stylish, modern aluminum benches at a very attractive entry point. They are also naturally rust-resistant, which is a significant advantage.
Cast iron benches, on the other hand, usually command a higher initial investment. The material is heavier, requires more energy to cast, and involves more labor-intensive finishing processes. This results in a higher price tag. But here’s where the comparison deepens. Cast iron is exceptionally heavy and robust, making it incredibly resistant to theft and vandalism. Its classic, ornate designs are timeless and often become permanent fixtures in a landscape. With a proper powder-coated or painted finish, it offers decades of service with minimal upkeep beyond occasional touch-ups.
So, while aluminum wins on upfront cost and corrosion resistance, cast iron offers superior longevity, stability, and a heirloom quality that can make it more cost-effective over a 20 or 30-year period. Your choice ultimately depends on your budget, aesthetic goals, and whether you prioritize immediate savings or lifelong value. For high-traffic public areas where durability is paramount, cast iron is often worth the premium. For temporary installations, coastal areas, or projects with strict initial budgets, aluminum is a fantastic, practical choice.
