Does your building feature newer architectural metalwork on its façade or anywhere else? Powder coating may be your best choice for preserving and protecting it. Powder coating offers durability without sacrificing beauty, providing protection from the elements while keeping your metalwork looking its best. Learn all about powder coating for architectural metalwork in our blog.
What Is Powder Coating?
Powder coating is a dry finishing process. It involves applying a powdered polymer substance to a metal surface. Unlike traditional paint, which employs solvents, powder coating is applied electrostatically and then cured under heat. This creates a hard, colorful finish that is both aesthetically pleasing and resistant to chipping, scratching, and corrosion. It’s better for the environment too.
Benefits of Powder Coating
For building owners, investing in powder-coated metalwork offers several advantages:
- Durability: Powder coating provides a tough, long-lasting finish that withstands the rigors of sunlight, water, ice, and more. This means metal elements like railings, gates, and window frames maintain their look for longer periods without fading or rusting.
- Eco-friendliness: Traditional solvent-based paints release volatile organic compounds (VOCs) that contribute to environmental pollution and are hazardous to those applying industrial coatings. Powder coating, on the other hand, contains no solvents and thus emits no VOCs, making it a greener choice for the environment and safer for workers.
- Variety: Choose from many different colors, tones, textures, and finishes—from high gloss to matte and from metallic to textured. Powder coating allows for customized design solutions that fit any architectural style.
Applications in Architectural Metalwork
Powder coating is widely used in various architectural and industrial applications. It is particularly popular for aluminum extrusions in window frames, doors, and curtain walls because of its resistance to weathering and UV radiation. Metal powder coating is also found in decorative metal elements such as fences, staircases, and balustrades. Protective and beautiful, it provides both function and form.
How Does It Work?
The powder coating process begins with a thorough cleaning of the metal surface to remove dirt, grease, and other contaminants. The metal is then sprayed with powder using an electrostatic gun, ensuring even application. Finally, the coated piece is heated in a special oven, allowing the powder to cure and form a smooth, durable finish.
