Effective anti-rainwater design for urban outdoor trash cans is crucial to prevent water ingress, which can lead to overflow, odor, and increased maintenance costs. The selection of materials plays a pivotal role in ensuring durability, functionality, and environmental resistance. Key materials include stainless steel, known for its corrosion resistance and strength, making it ideal for harsh weather conditions. Galvanized steel is another option, offering robustness and protection against rust through zinc coating. For plastic components, high-density polyethylene (HDPE) is preferred due to its waterproof nature, impact resistance, and ability to withstand UV radiation. Additionally, incorporating drainage systems made from PVC or similar plastics helps channel water away from the trash interior. The opening design often features overlapping lids or angled surfaces using these materials to minimize water entry. Ultimately, the choice depends on factors like climate, cost, and sustainability, ensuring trash cans remain efficient and long-lasting in urban settings.
