That's an excellent and very practical question. As a manufacturer, we get this a lot from city planners and facility managers. The short answer is: our bins are specifically engineered to handle significant temperature swings, but like any material, plastic has its limits, and we design with those in mind.
For extreme heat, our bins are made from high-density polyethylene (HDPE) or polypropylene, often with UV stabilizers. These materials typically have a heat deflection temperature well above 150°F (65°C). This means they won't warp or lose structural integrity under direct summer sun. However, we always advise against placing hot coals or direct flames inside, as sustained, localized extreme heat can cause damage.
Regarding extreme cold, plastic actually becomes more rigid and impact-resistant in the cold to a point. The real challenge is brittleness. Our formulations are designed for low-temperature impact resistance, often tested down to -20°F (-29°C) or lower. This ensures they won't crack if bumped or knocked over in freezing conditions. The one-touch open lids might move a little slower in deep winter, but they won't snap.
The key is in the resin quality and wall thickness. Cheaper, thin bins can become brittle in cold and may soften in sustained heat. Our commercial-grade bins use thick, roto-molded or injection-molded construction for consistent material strength. So, whether it's a scorching city summer or a freezing winter, you can expect our bins to maintain their shape, functionality, and durability for years. It's all about using the right plastic for the right job.
