Does Galvanized Steel Require Any Maintenance?

Yes, it does. Taking a proactive approach to galvanized steel maintenance will enhance its longevity and provide decades of corrosion-free performance. Despite its durability, exposure to harsh environments, contaminants or physical damage can reduce its effectiveness over time. We’ll examine the critical elements below to help you.

1. Clean Regularly

While the protective layers of zinc are robust and dependable, they can break down when consistently exposed to dirt, salt and pollutants. For basic cleaning, use mild detergent and water—you’ll want to avoid any harsh chemicals because you don’t want to damage the coating.

2. Inspect for Damage

As a part of galvanized steel maintenance, you should also be on the lookout for:

• White rust
• Dents
• Scratches
• Flaking

We recommend doing this at least twice a year, or more often if it is exposed to severe weather. 

3. Minimize Contact With Wet Packaging

Remember if you ship galvanized steel in bundles with banding or wrapping, moisture can become trapped inside. We suggest removing the plastic or shrink wrap once the material is in storage—particularly if it will be stored in an outdoor yard.

4. Be Proactive Against Electrochemical Reactions

Galvanized steel has robust corrosion protection, but you should still take a proactive approach toward maintenance. Even something as simple as contact with dissimilar metals can have an impact. 

You should use preventative measures like insulating gaskets, barriers or compatible fasteners. 

5. Handle Carefully to Avoid Surface Damage

While the zinc coating is durable, it can be scratched or chipped with rough handling, especially during loading, unloading, or repackaging. 

Remember that it’s also vital to pay careful attention to the type of environment, making note that coastal or industrial applications may require more frequent attention and detailed inspection. You should also evaluate surrounding materials and understand how they can impact the longevity of galvanized steel.

What Are Some Signs that Galvanized Steel Needs Maintenance?

One of the most obvious is visible signs of the beginning of rust. Others include:

• Evidence of scratches, dents or abrasions
• Blistering or flaking
• Moisture accumulation
• Extensive exposure to extreme temperatures
• Thinning coating (as per measurements)

What Is the Typical Lifespan of Galvanized Steel?

There are too many factors to provide a definite estimate. Everything from humidity to air pollution can affect how the zinc coating interacts with the environment. However, galvanized steel can last over 100 years in certain environments.

What Are the Best Practices for Cleaning Galvanized Steel?

We touched base on this earlier, but in general, ordinary mild detergent and a nylon brush is effective against dirt and the most common contaminants. Another effective solution is a wash under 1450 psa, using materials similar to those found in car washes.

Milder stains may be removed with household ammonia cleaners. However, it’s vital to completely and thoroughly rinse every clearance area with freshwater. 

It’s important to remember that if the zinc appears to have received extensive damage, the area may need to be evaluated. 

Avoid These Common Mistakes for Maintaining Galvanized Steel

Remember:

• Don’t use abrasives or harsh cleaners
• Don’t ignore signs of corrosion–even if they seem minor
• Don’t mix metals without isolation
