Corrosion Resistance
Corrosion resistance is a critical factor to consider when assessing materials for any construction project, especially those exposed to harsh environments, such as cattle guards. Cattle guards are barriers installed in roadways and pathways to prevent livestock from crossing into prohibited areas, without impeding vehicle movement. The choice of material, whether steel or aluminum, plays a pivotal role in the longevity and effectiveness of these guards due to their respective resistance to corrosion.
Steel cattle guards are often favored for their strength, but when it comes to corrosion, they can be vulnerable unless properly treated. Most steel guards are coated with a layer of paint or a specialized coating such as powder coating to protect against rust. Galvanized steel offers a higher level of protection, as it is coated with a layer of zinc that sacrificially corrodes to protect the underlying steel from rust. Regular maintenance is required to ensure the coatings remain intact and the steel does not begin to corrode.
On the other hand, aluminum naturally resists corrosion and rust does not affect it the same way it does steel. Aluminum forms a protective oxide layer when exposed to the atmosphere, which prevents further corrosion.
