That's an excellent question that gets to the heart of value versus initial price. While a plastic outdoor trash can almost always has a lower upfront cost, the long-term financial picture often favors metal. Here’s a natural breakdown of how the costs compare over time.
Initially, you'll find plastic bins are significantly cheaper. You can get a decent-sized one for a very reasonable price. Metal cans, especially those made from galvanized or powder-coated steel, require a higher initial investment. So, if your budget is tight right now, plastic seems like the clear winner.
However, the long-run story changes. Plastic is susceptible to cracking and becoming brittle from sun exposure (UV rays), extreme cold, and physical impacts. A strong wind can send it tumbling, leading to cracks. Animals can chew through it. Over a few years, you might be replacing that cheap plastic bin, adding to your total cost.
Metal cans, on the other hand, are built to endure. They resist cracking from impacts and temperature swings. Their main enemy is rust, but quality galvanized or coated models fight this off for years. A well-made metal can can easily last 10, 15, or even 20 years with minimal care, often outliving several plastic replacements.
There are other cost factors, too. Metal bins are heavier, deterring animals and wind. You save money on replacement bags if the plastic bin gets torn. They also simply look more substantial and can enhance property aesthetics, a subtle value add.
So, in the long run, the higher purchase price of a durable metal outdoor trash can is typically amortized over many more years of service. You pay more once instead of every few years. For a permanent spot like your backyard patio or driveway, the investment in metal usually pays off. For a temporary need or a very sheltered location, plastic's low initial cost might suffice. But for true long-term value and less hassle, metal is often the more economical choice.
