Protecting metal surfaces from corrosion is especially crucial in environments with high humidity, saltwater exposure, or extreme weather conditions. For years, e-coating has been widely used in the automotive and marine industries, thanks to its superior ability to reach crevices and hidden areas, providing an even and durable protective layer.
Here’s a look at how e-coating works, how Viewrail applies it, and how it fits into our finishing options.
What Is E-Coating?
E-coating (electrocoating) is a process where an electrically charged bath is used to deposit a thin, even layer of corrosion-resistant paint (or epoxy or other water-based solution) onto a metal part, like a post, handrail, or bracket. Think of it like applying paint from the inside out: the electric charge draws the coating into every nook and cranny, ensuring uniform coverage. Once e-coated, the part is rinsed and cured (baked) to lock in the protective layer.
Why It Matters: E-coating helps fend off rust and corrosion, making it an excellent choice for environments where metals face constant threats from moisture, salt, and other corrosive elements.
E-Coating Plus Powder Coating
Many manufacturers, including our team at Viewrail, opt to e-coat steel and other metal products to enhance their durability — particularly in demanding or coastal environments.
By first applying an e-coat, every inch of the steel receives a comprehensive layer of rust protection that reaches into crevices and corners. Once the e-coated parts are rinsed and cured, an additional powder coat finish can be applied to all visible surfaces. This layered method offers both enhanced corrosion resistance and a smooth, stylish appearance. In areas where hardware remains hidden or recessed, the e-coat alone may suffice, providing protection where it’s needed most without an added powder coat layer.
Combining e-coating with a powder coat finish creates a more resilient product that stands up against moisture, salt, and day-to-day wear.
Viewrail’s Three Levels of Finish
Viewrail offers three distinct finish options, each building on the same robust cleaning and pretreatment process:
Better — Standard Powder Coat
A durable, classic powder coat finish applied over thoroughly prepped steel.
Best — Superior Performance Powder Coat
A higher-grade powder coat with added UV protection for increased fade resistance over time.
Exceptional — Superior Performance Powder Coat + E-Coat
The ultimate corrosion protection, adding e-coat underneath the fade-resistant powder coat. Ideal for harsh environments or anyone seeking maximum longevity.

Why E-Coating Plus Powder Coat?
- Enhanced Corrosion Resistance: E-coating reaches deep into seams and corners where corrosion typically begins, while powder coating adds another layer of protection.
- Longevity and Durability: The two-step approach extends the life of steel parts, minimizing the need for replacements or repairs down the road.
- Consistent Finish: Powder coating on top of an e-coat ensures a smooth, visually appealing surface — especially important for visible architectural elements.
Choose the Right Solution for Your Needs
E-coating is a great solution for corrosion resistance, especially when paired with powder coating. By applying e-coat first, then covering it with our standard or superior performance powder coat, we can ensure your steel stringers and railing hardware are ready to stand up to coastal conditions and everyday wear.
Whatever finish option you choose, you can trust that your Viewrail system is engineered to look great — and last — wherever your project is located.
