Our metal comes with a 10-year edge rust warranty. Does the other guys’?
What is Edge Rust?
Edge rust is corrosion that starts at the cut edges of metal panels, where the raw steel is exposed.
Why We Need to Talk About It
- Edge rust often starts sooner than people expect.
- Not years later. Sometimes it’s months.
- Once it starts, it can’t be undone.
- Most warranties won’t cover it.
That’s why edge protection is one of the most important things to look at when comparing proposals.
Our Approach
With us, metal building edge rust warranty protection isn’t an upgrade or a line item on the initial proposal. It’s built in.
Most proposals simply say “metal siding” or “steel panels” without explaining steel thickness, edge protection, what actually prevents rust, or what the warranty really covers.
We’re here to explain what you’re getting and what truly protects your investment, even if it means our quote isn’t the cheapest one on the table. We choose materials we stand behind long after the build is finished, because we’re focused on what lasts, not just what’s next.
What Our Metal Is Made Of
Think of metal panels like a system of layers working together. Each layer has a job, and when one of them is weak, the entire panel can fail over time.
- Steel
- Galvanization
- Paint
1. Steel
When shopping for metal roofing or siding, it’s important to understand the substrate, which is simply the steel underneath the paint. This is the backbone of the panel. Not all metal is the same, and choosing lighter or lower-quality steel can lead to dents, oil canning, and a shorter lifespan.
- We use heavier 26 gauge steel for added strength
- This is about 30% heavier than the 29 gauge metal many builders typically use
- More steel means stronger panels, better impact resistance, and long-term durability for your building
2. Galvanization
Bare steel will rust, so once the steel is formed, it needs protection from moisture, rain, snow, and humidity. That protection process is called galvanization.
Galvanization is the process of coating steel with zinc. Zinc acts like a shield, keeping moisture from reaching the steel. Even more importantly, zinc protects the steel by slowly wearing away first, helping prevent rust from forming on the steel underneath.
- We use G90 galvanization, which provides about 40% more zinc than common G60 coatings and more than double the protection of some economy panels.
- The more zinc on the steel, the stronger the protection against corrosion. This added zinc creates a thicker, more durable barrier that protects the most vulnerable parts of the panel and plays a major role in how long your building holds up over time.
- Zinc protection is especially important at cut edges and fastener points, where the steel is exposed and rust usually starts first.
3. Paint
The outer coating, or paint system, is just as important as what’s underneath. This is the layer you see, but it does much more than affect appearance.
It is exposed to sun, wind, rain, snow, and temperature changes every single day. Over time, lower quality paints fade, chalk, and break down, leaving the metal underneath more vulnerable.
With us, you can choose either an SMP or a 70% PVDF paint system such as Kynar or Trinar
SMP paints are often used to reduce upfront cost, but they typically fade faster and show wear sooner, especially in direct sunlight
- Maximum color stability over time
- Long-term appearance that resists fading and chalking
- Superior finish durability compared to standard SMP paint systems
- Protects the steel below while helping your building maintain its original color longer
- Performs better in direct sunlight and harsh weather, keeping your building looking newer for longer
Why We Build Differently
We don’t choose materials based on what looks good on paper or saves a few dollars upfront. We choose materials based on how they perform years down the road, when the build is no longer new and the real test begins. Heavier steel, higher zinc protection, and premium paint systems all work together to protect the most vulnerable parts of your building. That’s why we can stand behind our metal with an edge rust warranty and confidence in how it will age. It’s not about being the cheapest option. It’s about building something that holds up, looks good longer, and earns its keep over time.
