Powder Coated Aluminum Railing

Powder Coated Railings Paint Finish

Elevate your outdoor spaces with DekSmart Railings’ exceptional powder coated aluminum railing system. Our powder coated railings are engineered for low maintenance and high performance, making them the perfect choice for your deck railing needs – even in harsh weather conditions.

Our aluminum & glass railing systems are sturdy and easy-to-install on your patio, deck, or staircases (indoor & outdoor). Unlike liquid paint finishes, powder coated railings emit zero (or near zero) volatile organic compounds, making them an environmentally-friendly choice.

All DekSmart Railings powder coat finishes comply to:

  • NAAMM’s “Metal Finishes Manual for Architectural and Metal Products” for recommendations for applying and designating finishes
  • ASTMB117-97 (3000 hr salt spray adhesion)
  • A.A.M.A.4 2604 colour uniformity, film adhesion, impact and chemical resistance criteria

The Powder Coating Process

Treatment of Raw Aluminum

All DekSmart Railings exposed aluminum components are treated before powder coating through a full multi-stage pretreatment process.

  • First stage – treating the components with a heated alkaline based solution to remove oils and contaminates
  • Second stage – freshwater rinse
  • Third stage – reverse osmosis rinse
  • Fourth stage – E-CLPS sealer coat used to provide a superior bond for the powder coat finish to the aluminum
  • Fifth stage – aluminum components are oven dried leaving a nearly colourless coating

Application Process

Applying the Powder Paint

All Deksmart Railing components receive a baked-on powder coated finish in either a smooth or textured finish.

  • Powder coat finish is electrostatically applied and are thermosetically cured.
  • 8 standard colours, custom colours available and are quoted separately.
  • All powder coat paint is Polyester T.G.I.C. Free .
  • Powder coat finish is minimum 3 mil thickness for smooth gloss finish and 4 mil thickness for textured finish.

Powder Paint Quality Control

Powder-coated components are subjected to a comprehensive quality control program.

  • A visual check for powder paint consistency after the electrostatic application is performed under high-intensity lighting pre-thermoset curing
  • After thermoset curing, a visual check for powder paint consistency is performed.
  • An electronic gauge using the eddy current principle is used to measure paint thickness. (ASTM Practice D7091 for non-destructive measurements)
  • A boil test and cross-hatch test are performed on each paint batch to confirm paint adhesion as per suppliers’ recommendations

Benefits of Powder Coated Aluminum Railings

  1. Virtually Maintenance Free:

    Powder coating provides a durable and resilient finish free from rusting, flaking, or peeling. Powder coated railing systems only require a light clean and minimal seasonal maintenance to keep them looking great for years or decades to come.

  2. UV Ray Resistance:

    The powder coating process creates a protective barrier, making aluminum railings resistant to UV rays. This resistance helps prevent fading and ensures a long-lasting, visually appealing finish.

  3. Non-Toxic:

    Powder coating is an environmentally friendly option as it contains almost no volatile organic compounds (VOCs) and does not release harmful chemicals into the air during application. This makes it a non-toxic choice for aluminum railings.

  4. Corrosion Resistance:

    Aluminum railings are naturally resistant to rust, but powder coating adds an extra layer of protection, creating a barrier against corrosion caused by exposure to the elements, moisture, and oxygen.

  5. Durable Finish:

    The curing process during powder coating enhances the hardness and durability of the finish. The resulting coating on aluminum railings is tough and can withstand harsh weather conditions, ensuring a longer lifespan.

  6. Heat Resistance:

    Powder-coated aluminum railings exhibit heat resistance, making them suitable for outdoor applications where exposure to sunlight and high temperatures is common.

  7. Resin Adhesion:

    The electrostatically charged powder particles adhere to aluminum surfaces, creating a tight bond. This resin adhesion enhances the strength and longevity of the powder-coated finish on railings.

  8. Flake Prevention:

    Unlike traditional paint, powder coating does not flake over time. The cured powder forms chemical bonds, providing a consistent and even finish on aluminum railings, preventing flaking issues.

  9. Elegant Visual Appeal:

    Powder coating imparts an aesthetically pleasing finish to aluminum railings, enhancing their visual appeal. The variety of colors and stylish shapes available make powder-coated aluminum a preferred choice for attractive outdoor structures.

  10. Environmental Responsibility:

    Powder coating is considered environmentally responsible due to its low environmental impact. With minimal VOCs and no heavy metals like chrome, it aligns with eco-friendly practices, making it a sustainable choice for aluminum railings for your home or business.
