That's a great question! It really comes down to what the bin is built for. The cheap, lightweight ones you might buy for your patio are a completely different product from the heavy-duty cans you see in parks, downtown areas, or outside restaurants.
The expensive ones are engineered for a brutal life. They're made from incredibly durable materials like thick, welded stainless steel, commercial-grade plastic that won't crack in the sun or cold, or powder-coated steel that resists rust. This alone costs significantly more than thin, molded plastic.
Then, consider the abuse they face. They need to withstand constant public use, attempted vandalism, and harsh weather for years. Expensive bins often have features like tamper-resistant locks, reinforced openings, and anchored bases to prevent theft or tipping. They're also designed for efficient servicing with larger capacities and easy-lift lids for sanitation workers.
Finally, you're paying for specialized design and compliance. Municipalities and businesses often need bins that meet specific standards, blend with urban design, promote recycling (with multi-stream units), or bear custom logos. The engineering for safety, durability, and functionality in a public setting is what you're ultimately investing in. So, while the price tag can be surprising, it reflects a product built for a 24/7 job in the real world, not just occasional backyard use.
