What wrought iron wall thickness prevents chewing damage from wildlife?

When selecting wrought iron fencing to protect property from wildlife, understanding the appropriate wall thickness is crucial for preventing chewing damage. Most wildlife species, including rodents, raccoons, and smaller mammals, cannot effectively chew through wrought iron with a thickness of 1/8 inch (approximately 3.1mm) or greater. This thickness provides sufficient resistance against the biting force of common urban and suburban wildlife.

The durability of wrought iron against animal damage stems from both its material hardness and thickness. While determined animals like beavers or large rodents may attempt to gnaw on metal surfaces, a minimum thickness of 3mm generally withstands their dental pressure. For areas with particularly persistent wildlife or larger species, increasing thickness to 1/4 inch (6.35mm) provides additional security.

Several factors influence the necessary thickness for wildlife protection. The animal species in your region, their motivation to access your property, and the fence's structural design all contribute to durability requirements. Regular inspection remains important, as even thick wrought iron can suffer surface damage from persistent chewing attempts, though penetration is unlikely at recommended thicknesses.

Proper installation and maintenance further enhance protection. Ensuring there are no sharp edges that might attract chewing behavior and promptly addressing any scratches or imperfections that could provide a starting point for animals helps maintain the fence's integrity over time. Combining adequate thickness with good fence design creates an effective barrier against wildlife intrusion through chewing.
