Urban outdoor trash cans require robust rodent-proof nets that can withstand harsh environmental conditions while maintaining structural integrity. The ideal material must demonstrate exceptional corrosion resistance to combat moisture, chemical exposure, and temperature fluctuations. Stainless steel, particularly grades 304 and 316, offers superior corrosion resistance due to its chromium content that forms a protective oxide layer. Galvanized steel provides excellent protection through zinc coating that acts as a sacrificial barrier against rust. Aluminum alloys with proper anodization create a durable, corrosion-resistant surface ideal for coastal environments. The material should resist pitting corrosion from chlorides in de-icing salts and atmospheric pollution. Powder coating or polymer coatings can enhance corrosion resistance while adding color for visibility. The mesh must maintain its anti-corrosion properties without compromising ventilation or rodent prevention capabilities. Regular maintenance and proper installation further ensure long-term performance against corrosion in urban settings.
What anti-corrosion performance should the material of the rodent-proof net of urban outdoor trash cans have?
