Metal Building and Rust
Steel buildings are naturally tough. However, even these durable structures can be susceptible to rust and corrosion over time if not properly maintained.
However, with the right care, you can minimize the potential for damage from oxidation and corrosion. In this guide, we’ll break down what causes rust and corrosion to occur and some of the best ways to prevent them.
If you’re in the market for a metal building or just a proud new owner, this handy information can save you money and years of headaches.
What Causes Rust and Corrosion?
What’s the deal with rust and corrosion? Are they the same thing? Not exactly.
Rust is a type of corrosion, specifically one that affects iron and its alloys like steel. It’s what happens when iron meets oxygen and rain, snow, or even just humidity. That reddish-brown stuff you see flaking off metal? That’s good old rust.
Corrosion, on the other hand, is a broader term. It refers to the natural process where metal deteriorates due to chemical reactions. This is often caused by salty air near the coast, industrial pollution, and even acid rain.
Whether it’s corrosion or rust, neither one is welcome on your building, so you need to take serious steps to keep them away.
Why Metal Structures Resist Rust and Corrosion
How are metal buildings able to take such a beating and live to tell the tale? Much of it comes down to the natural durability of the materials used. They feature:
- Galvanized Steel
Metal building paneling and framing are typically coated in a protective layer of zinc. This zinc acts like a bodyguard—it corrodes first and protects the steel underneath.
- UV and Corrosion-Resistant Coatings
Exposure to sunlight and moisture is a deadly combo for most materials. But UV-resistant coatings block out the sun’s harsh rays and prevent moisture from settling into seams or joints.
- UV-Resistant Paint
High-quality, weather-resistant paint adds another layer of defense to your building. Not only does it help prevent corrosion, but it also keeps your building looking sharp year after year.
How to Prevent Rust on Your Metal Building
Even with all that protection, a little routine care goes a long way. Below, we’ve put together a simple maintenance checklist to keep rust and corrosion from ever becoming a problem with your metal building:
- Inspect Regularly
Do a walkthrough every few months. Look for scratches, dents, or chipped paint—anywhere moisture could sneak in. Catching it early makes all the difference.
- Keep it Clean
Dirt and debris trap moisture. Use a hose or pressure washer to rinse your building off now and then, especially after heavy storms or long dry spells when grime builds up.
- Check for Standing Water
Make sure gutters are clear, and drainage around the building is working properly. Standing water near the base can creep into joints and corners, starting corrosion from the ground up.
- Touch Up Paint as Needed
If you spot any areas where paint is peeling or worn, grab some color-matched, rust-resistant paint and touch it up. It’s a quick job that could save you a costly repair down the road.
- Re-seal and Coat When Needed
Depending on your environment, you might need to reapply protective coatings every few years.

Metal Building Maintenance FAQs
When it comes to keeping your steel building in tip-top shape, it pays to ask the right questions. Below, we’ve answered some of them!
- What’s the main cause of rust in metal buildings?
Answer: Rust forms when iron or steel reacts with oxygen and moisture, especially in the form of rain, snow, or high humidity. Over time, this chemical reaction breaks down the metal and causes that flaky, reddish-brown buildup we all dread.
- How is corrosion different from rust?
Answer: Rust is actually a type of corrosion that specifically affects iron and steel. Corrosion is a broader term that refers to the gradual breakdown of metal due to moisture, salt, chemicals, or pollution.
- What materials help prevent rust in metal buildings?
Answer: Galvanized steel is coated with zinc, which helps block rust from forming. Add in UV-resistant coatings, corrosion-resistant paints, and quality sealants, and your building is set up for long-term protection.
- How often should I inspect my metal building for signs of rust?
Answer: A good rule of thumb is to inspect your building every 3–6 months. It’s especially important to check after extreme weather, such as heavy rain, snow, or high winds, which can expose weak spots.
- What should I do if I find rust starting to form?
Answer: Don’t panic! Light surface rust can usually be sanded down and repainted with a rust-inhibiting primer and topcoat. The key is catching it early before it spreads or causes structural damage.
