Powder Coating
Colorful corrosion-resistant coating to protect and enhance your Specialty Metals & Gratings project!
What is Powder Coating?
Powder coating is a dry finishing process that creates a durable, protective surface on metal products. During application, finely ground, pigmented powder particles are electrostatically charged and sprayed onto a grounded metal surface, ensuring even coverage and adhesion.
The coated material is then cured in a controlled oven environment. As it heats, the powder melts, flows, and chemically bonds to form a continuous finish. The result is a high-quality coating with excellent resistance to corrosion, abrasion, impact, and cracking. In many applications, powder coating provides a tougher, longer-lasting finish than conventional liquid paint.

When to Choose Powder Coating for Your Project
Powder coating is an effective solution when both performance and appearance are critical. It is commonly specified for architectural and industrial applications requiring long-term durability and visual consistency. Because powder coatings contain little to no volatile organic compounds (VOCs), they can support environmentally responsible building initiatives, including LEED-friendly projects, when properly specified.
Customers specify Powder Coating Services for:
- Durable protection in demanding environments
- A clean, uniform finish with consistent color
- Enhanced resistance to wear in high-traffic or high-touch areas
- A low-VOC alternative to traditional liquid coatings
Comparing Finish Options
- Mill finish: The natural, untreated appearance of the material. Suitable for functional applications but offers limited corrosion resistance and minimal aesthetic enhancement.
- Paint: Improves appearance and provides basic surface protection. However, liquid coatings may wear more quickly in high-traffic or heavily used environments.
- Powder coating: Delivers a durable, uniform finish with enhanced resistance to corrosion and abrasion. Ideal for applications requiring both visual consistency and long-term performance.
BENEFITS OF POWDER COATING
- Durable Protection: Resists corrosion, impact, and surface wear
- Uniform Finish Quality: Creates a smooth, continuous coating with consistent thickness and coverage
- Enhanced Aesthetics: Provides vibrant, long-lasting color with a clean, professional appearance
- Extended Product Life: Improves resistance to chemicals, weathering, and tarnish, depending on environment and specifications
Architectural and Design Applications
Ideal for architectural aesthetics, powder coating allows for highly specific color options for consistent visual impact in public spaces. It is frequently used in both interior and exterior architectural environments where design and durability must work together.
For decorative applications such as Designer Perforated Metal, finish selection enhances pattern visibility and overall design intent. Designers can reference McNICHOLS' RAL color options to achieve precise color matching for branded environments, including schools, municipalities, and commercial spaces.
Matching logos, school emblems, and corporate brand colors is also achievable, helping create a cohesive and visually consistent finished space.
Industrial and Commercial Applications
In industrial environments, color functions as a critical safety communication tool. It functions as a critical safety communication tool. Standardized color systems, aligned with OSHA and ANSI guidelines aligned with OSHA and ANSI guidelines use specific colors to identify hazards, designate safe areas, and mark emergency equipment.
For example, yellow is highly visible and commonly used to draw attention in active work areas, helping workers quickly recognize potential hazards. Red is typically used to identify fire protection equipment and emergency stop controls. These visual cues support faster response times and contribute to safer, more compliant facilities.
In addition to supporting OSHA-aligned safety practices, powder coating adds a durable, protective layer to metal components exposed to daily wear, handling, and environmental conditions. This includes:
- Catwalks
- Equipment covers
- Handrails and guardrails
- Industrial safety barriers
- Machine guards and protective enclosures
- Partitions and screens
- Stair Treads
- Signage
