Custom Spring Coatings for Specialized Springs
Metal Spring Coatings From Your Trusted Industrial Spring Maker and Industrial Spring Supplier
With our custom spring coating for square springs, custom springs, heavy-duty springs and any type of metal spring you can imagine, we help a variety of industries and manufacturers bring high-quality products to market and improve existing products.
The experienced team at Tennessee Spring & Metal even works with manufacturers to optimize products, develop new processes, and bring new inventions and innovations to customers. Recently, we partnered with a well-known global foodservice systems manufacturer to help improve automation in the fast food industry.
Custom spring coatings help products last longer, perform better, and stand out from the sea of spring sameness.
We’re an American spring company that makes 100% traceable metal springs and we offer a wide range of in-house spring coatings and spring surface treatments. We also partner with American-owned and operated industrial coating suppliers to provide a wide range of custom coatings for all types of industrial springs.
Our metal spring coating solutions can help prevent corrosion and improve spring hardness. We can also match branding with custom colors and print company names and logos on your products.
Selecting the right spring – square springs, round springs, rectangular springs, or wire forms – the perfect spring metal, and the right metal spring coating and surface treatment will ensure your springs are made to last.
Tennessee Spring & Metal has a long history of manufacturing metal spring and coating springs and wire forms for industrial applications.

Chemical Spring Coatings
To extend the usable life of an industrial spring and to reduce friction and noise, we can add permanent lubrication or a Teflon™ coating to any spring. Other common chemical treatments for metal springs include phosphoric acid washes to improve oxidation resistance and enamel paints for long-lasting corrosion protection. We also offer environmentally friendly, water-based Thermadep coating for superior protection.
Galvanizing Springs
To protect our springs from the weakening effects of corrosion, the hot-dip galvanizing process adds a thick layer of zinc iron alloy to the surface of a steel spring. This coating protects springs from rust formation.
Electroplating Industrial Springs
Electroplating springs involves passing an electric current through an electrolyte solution. This is accomplished by dipping two terminals — electrodes — into the electrolyte and connecting them into a circuit with a battery or other power supply.
When the electricity flows through the circuit, the electrolyte splits up and some of the metal atoms that it contains are deposited in a thin layer on top of one of the electrodes. Voila! Your metal spring has been electroplated. All kinds of metals can be plated in this way, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum, and lead.

Electroplating industrial springs improves the appearance of springs and can also improve an item’s value. Electroplating also improves wear and corrosion resistance.
Electropolishing Metal Springs
On the other end of the spectrum from spring electroplating we have spring electropolishing. Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. The process leaves a shiny, smooth, ultra-clean surface finish.
“Also known as electrochemical polishing, anodic polishing or electrolytic polishing, electropolishing is especially useful for polishing and deburring parts that are fragile or have complex geometries. Electropolishing improves surface finish by reducing surface roughness by up to 50%” (BestTechnologyinc.com)
Powder Coating Custom Springs
Powder coating is a type of protective and decorative coating that is applied as a free-flowing, dry powder. Unlike liquid paint or other solvent-based coatings, which are delivered via an evaporating solvent, powder coating is applied to springs electrostatically and then cured under heat or with an ultraviolet light source.
Powder coatings typically create a hard, smooth finish that’s even more durable than conventional paint coatings. We offer both thermoplastic and thermoset polymer coatings.
