The Spectrum Aquatics 3-Step Process combines electropolishing, passivation, and our exclusive Spectra Shield® treatment to maximize corrosion resistance, improve cleanability, and dramatically extend the life of stainless steel aquatic equipment. Unlike many manufacturers that stop after electropolishing and passivation, Spectrum adds a third protective layer that helps shield stainless steel from moisture and harsh pool chemicals.

After reading this guide you'll understand:
Even stainless steel can corrode in harsh aquatic environments if it isn't properly finished and protected and maintained.
Why? Commercial pools create one of the most demanding environments for metal.
Equipment is continually exposed to:
Without proper surface treatment, contaminants can become embedded in the metal, eventually leading to corrosion, staining, or pitting.
That's why the finishing process matters just as much as the stainless steel itself.
Electropolishing removes microscopic imperfections and contaminants from the stainless steel surface, creating a smoother, cleaner finish.
Think of electropolishing as microscopic polishing.
During fabrication, tiny imperfections and contaminants become embedded within the metal.
Electropolishing removes these imperfections to create a smooth, mirror-like finish that:
The smoother the surface, the fewer places contaminants have to collect.
Passivation strengthens stainless steel's natural corrosion resistance by enhancing its protective chromium-rich surface.
After electropolishing, Spectrum passivates every stainless steel component.
Passivation is a chemical treatment that removes free iron and other contaminants from the metal surface.
The result is a stronger chromium oxide layer that naturally protects stainless steel from:
Most high-quality commercial aquatic equipment should include passivation.
Spectra Shield® is Spectrum Aquatics' proprietary third layer of protection that helps keep moisture and pool chemicals out of the stainless steel surface.
This is where Spectrum differs from nearly every other manufacturer.
Many companies electropolish.
Many companies passivate.
Most stop there.
Spectrum continues with a third proprietary treatment called Spectra Shield®.
Spectra Shield® works by embedding itself into the microscopic grain structure of the stainless steel surface, creating an additional barrier against:
Unlike waxes or temporary coatings, Spectra Shield®:
Instead, it quietly protects the equipment every day throughout its service life.
________________________________________________
Because every additional manufacturing step adds cost, time, and quality control requirements.
Applying electropolishing, passivation, and a proprietary protective treatment requires additional labor, equipment, and inspection.
For some manufacturers, reducing production costs takes priority.
At Spectrum Aquatics, we believe the long-term durability of our products is worth the extra effort.
It's one of the reasons our stainless steel equipment continues performing in some of North America's toughest aquatic environments.
The Spectrum Aquatics 3-Step Process doesn't just protect bare stainless steel, it also creates the ideal foundation for powder coating. By thoroughly cleaning and preparing the metal through electropolishing and passivation before applying our proprietary Spectra Shield® treatment, we help ensure powder coat adheres more uniformly, delivers a smoother finish, and provides longer-lasting durability in harsh aquatic environments.
Spectrum Aquatics uses only American-made stainless steel sourced from select mills across the United States.
Combined with our manufacturing process, this provides:
Every stainless steel component is manufactured in Missoula, Montana, where every weld is carefully hand polished before entering the 3-Step Process.
That attention to detail helps eliminate surface contaminants that could otherwise become corrosion points later in the product's life.
| Manufacturing Process | Typical Manufacturer | Spectrum Aquatics |
|---|---|---|
| American stainless steel | Sometimes | ✅ |
| Electropolishing | Often | ✅ |
| Passivation | Often | ✅ |
| Proprietary corrosion treatment | Rare | ✅ |
| Hand-polished welds | Varies | ✅ |
| Complete 3-Step Process standard on all stainless products | Rare | ✅ |
Many buyers compare:
Few compare how the stainless steel was finished.
Two products may look nearly identical on installation day. Five or ten years later, their appearance, and maintenance requirements, can be dramatically different.
The manufacturing process often determines the lifespan of the equipment.
When evaluating commercial aquatic equipment, don't just ask: "What grade of stainless steel is it?"
Also ask:
Those answers often tell you far more about long-term durability than the stainless steel grade alone.
| Myth | Fact |
|---|---|
| Stainless steel never rusts. | Stainless steel can corrode in harsh aquatic environments if it isn't properly finished and maintained. |
| All stainless steel products are manufactured the same way. | Manufacturing and finishing processes vary significantly between manufacturers. |
| Electropolishing alone is enough. | Electropolishing is excellent, but additional protection can further increase corrosion resistance. |
| Surface finish doesn't matter. | Surface finish plays a major role in cleanability and long-term durability. |
Even the highest-quality stainless steel benefits from routine maintenance. That's why Spectrum Aquatics developed Spectra-Clean™, our professional-grade stainless steel cleaner and passivation solution designed specifically for commercial aquatic environments. Regular cleaning helps remove chlorine residue, mineral deposits, and surface contaminants while restoring the beautiful finish and helping maximize corrosion resistance. Best of all, it's available on our online store for quick and convenient ordering.
Before purchasing commercial pool equipment, ask whether it includes:
| ✔ Checklist |
|---|
| American-made stainless steel |
| Electropolishing |
| Passivation |
| Additional corrosion protection |
| Hand-finished welds |
| Long-term replacement part availability |
| Commercial aquatic manufacturing expertise |
| Proven performance in harsh aquatic environments |
Electropolishing significantly improves corrosion resistance by creating a smoother surface, but it is most effective when combined with passivation and proper maintenance.
Passivation removes free iron contaminants and enhances the stainless steel's natural protective chromium oxide layer.
Spectra Shield® is Spectrum Aquatics' proprietary third layer of protection that provides additional defense against moisture and harsh aquatic chemicals.
Yes. Every Spectrum Aquatics stainless steel product goes through our complete 3-Step Process as part of our standard manufacturing process.
All Spectrum Aquatics stainless steel products are manufactured in Missoula, Montana using American-made stainless steel sourced from select U.S. mills.
Commercial aquatic equipment represents a long-term investment. While many stainless steel products may appear similar on the surface, the manufacturing process behind them can make a significant difference in how they perform over years of exposure to chlorine, moisture, UV light, and demanding aquatic environments.
At Spectrum Aquatics, every stainless steel product is built with longevity in mind. From American-made stainless steel and meticulous hand-finishing to electropolishing, passivation, and our exclusive Spectra Shield® treatment, our 3-Step Process is designed to deliver exceptional durability and corrosion resistance for the life of your equipment.
From ADA-compliant pool lifts and starting blocks to handrails, ladders, lifeguard chairs, and climbing walls, every Spectrum Aquatics stainless steel product is manufactured using our exclusive 3-Step Process as a standard, not an upgrade.
If you're planning a new facility, renovating an existing pool, or comparing commercial aquatic equipment, our team is here to help you choose products engineered for long-term performance.
