When choosing outdoor benches, the cost difference between aluminum and steel is a major factor, but it's only part of the story. Initially, aluminum benches often carry a higher price tag than their steel counterparts. This is due to the material costs and manufacturing processes involved. However, this upfront cost doesn't tell the whole tale of long-term value.
Steel benches, particularly those made from mild steel, are generally less expensive to purchase. But steel is prone to rust when exposed to the elements unless it has a high-quality, durable powder-coated finish or is made from galvanized or stainless steel (which increases the cost significantly). Without proper and regular maintenance, a steel bench can corrode, leading to costly repairs or premature replacement.
Aluminum, on the other hand, is naturally corrosion-resistant. It doesn't rust, and its protective oxide layer means it requires minimal upkeep—often just occasional cleaning. While you pay more initially, you save substantially on maintenance and enjoy a much longer lifespan, especially in coastal or humid environments. The lightweight nature of aluminum can also reduce shipping and installation costs.
For high-traffic public spaces or areas with harsh weather, the long-term investment in aluminum often proves more economical. For temporary installations or controlled environments where maintenance is guaranteed, a powder-coated steel bench can be a budget-friendly choice. Ultimately, consider total cost of ownership: purchase price, installation, maintenance, and expected lifespan to determine the true cost comparison for your specific project.
