Powder-coated steel

by Vlad Fokin on January 22, 2025

Saunas are a hallmark of relaxation, wellness, and tradition. They have evolved from simple wood-heated enclosures to sophisticated spaces incorporating advanced materials and designs. One of the increasingly popular materials in modern sauna construction is powder-coated steel. This versatile material combines durability, style, and practicality, making it ideal for both commercial and home saunas.

What Is Powder-Coated Steel?

Powder-coated steel is a type of steel that has been treated with a special coating process to enhance its durability and appearance. The process involves applying a fine powder, usually made of polyester or epoxy, to the steel surface. The powder is electrostatically charged to adhere uniformly to the steel, after which it is heated to form a smooth, durable finish. This coating is not only aesthetically pleasing but also highly resistant to corrosion, scratches, and wear.

Why Choose Powder-Coated Steel for Saunas?

Saunas require materials that can withstand high temperatures, fluctuating humidity levels, and constant exposure to moisture. Powder-coated steel excels in these areas, offering a range of benefits that make it an ideal choice for sauna construction and design.

1. Corrosion Resistance

The sauna environment, with its combination of heat and moisture, can lead to rapid corrosion of untreated metals. Powder-coated steel has a protective layer that prevents rust and corrosion, ensuring longevity even in high-humidity conditions.

2. Durability

The powder coating creates a hard surface that resists scratches, dents, and wear. This is particularly important for saunas that see frequent use, such as in spas, gyms, or hotels.

3. Aesthetic Versatility

Powder-coated steel is available in a wide range of colors and finishes, from matte to glossy, allowing sauna designers to create a sleek, modern aesthetic or match the steel components with traditional wood elements. The smooth surface also resists staining and discoloration, maintaining its pristine appearance over time.

4. Low Maintenance

The non-porous coating of powder-coated steel makes it easy to clean and maintain. A simple wipe with a damp cloth is often enough to keep it looking new, which is particularly beneficial for commercial saunas where hygiene is a priority.

5. Eco-Friendly Process

Powder coating is an environmentally friendly finishing process. Unlike traditional liquid paints, it doesn’t rely on solvents or release volatile organic compounds (VOCs) into the atmosphere. This aligns with the eco-conscious ethos often associated with sauna culture.

Applications of Powder-Coated Steel in Saunas

Powder-coated steel can be used in various components of sauna construction, including:

  • Frames and Structural Elements: Steel frames provide sturdy support for glass panels and other features in modern saunas. The powder coating ensures these elements remain rust-free and visually appealing.
  • Benches and Accessories: While wood is the traditional material for sauna benches, powder-coated steel is sometimes used for support structures or in hybrid designs that combine steel and wood for a contemporary look.
  • Lighting Fixtures and Vents: Powder-coated steel is often used for lighting frames, air vents, and other small fittings, ensuring they stand up to the heat and moisture while blending seamlessly with the overall design.
  • Exterior Panels: The outside of a sauna can incorporate powder-coated steel for a modern, industrial appearance that contrasts beautifully with natural wood interiors.

Considerations When Using Powder-Coated Steel in Saunas

While powder-coated steel offers many advantages, there are some considerations to keep in mind:

  • Heat Conductivity: Steel conducts heat efficiently, which can make it hot to the touch in high-temperature environments. Designers typically ensure that steel components are used in areas where they are unlikely to come into direct contact with users, or they incorporate insulating materials.
  • Cost: Powder-coated steel can be more expensive than untreated steel or other materials. However, its long-term durability and low maintenance can offset the initial investment.
  • Compatibility with Sauna Aesthetics: While powder-coated steel works well in modern and industrial designs, it may need to be carefully integrated into traditional sauna settings to maintain a cohesive look.

Conclusion

Powder-coated steel is a robust, versatile, and visually striking material that is well-suited to the unique challenges of sauna construction. Its resistance to corrosion, durability, and low maintenance requirements make it an excellent choice for both residential and commercial saunas. Whether as a structural element, a design feature, or a finishing touch, powder-coated steel brings a contemporary edge to this timeless wellness tradition.

By combining innovation with functionality, powder-coated steel ensures that saunas remain both beautiful and enduring spaces for relaxation and rejuvenation.
