How to Choose the Best Fiberglass Color and Surface Profile

Learn how the color and surface profile of your Fiberglass Grating can affect durability, visibility, safety, and more.

Matching Fiberglass Grating to Your Environment

Fiberglass Grating has become a staple in industrial, commercial, and even architectural applications due to its durability, corrosion resistance, and versatility. To support these applications, McNICHOLS offers a wide selection of Fiberglass solutions with a variety of colors and surface profiles to meet diverse project requirements. Understanding the differences in color and surface profile is key to selecting the right grating for your project. In this post, we’ll explore the available McNICHOLS® Fiberglass Grating colors and surface profiles, along with their benefits and ideal applications.

The Importance of Color in Fiberglass Grating

Color in Fiberglass Grating is more than just an aesthetic choice, as it can also serve important functional and safety purposes. For example, highly visible colors can improve workplace safety, while neutral tones may better complement architectural settings.

Selecting the right color can also support facility branding, improve visual contrast, and help maintain a clean appearance over time.

Key Functional Benefits of Fiberglass Grating Colors

  • Safety: Bright colors, such as yellow, enhance visibility, helping reduce trip hazards and support OSHA compliance.
  • Branding: Custom colors can align with corporate branding or complement facility design.
  • UV Resistance: Lighter or neutral colors typically provide better resistance to fading in outdoor environments.

McNICHOLS® Fiberglass Grating is available in several standard colors, each offering distinct functional and visual advantages:

McNICHOLS® Fiberglass Grating Molded, Square Grid, MS-S-150, Fiberglass, SGF Polyester Resin, Yellow, 1-1/2" Grid Height, 1-1/2" x 1-1/2" Square Grid, Grit Surface, 70% Open Area
ITEM F261131C

Yellow

Yellow is highly visible, making it ideal for safety applications such as walkways, platforms, and stair treads in industrial settings. In addition, it helps clearly define walking areas and safety zones. However, it may be more prone to UV fading with prolonged outdoor exposure.

ITEM F261111L

Dark Gray

This color offers a neutral, professional appearance that blends well with architectural and commercial environments. For example, dark gray is utilized in public spaces or projects where aesthetics are a priority. It is typically the most resistant to visible fading over time.

ITEM F26111LC

Light Gray

Light gray offers a clean, modern appearance that works well in commercial, architectural, and public-facing environments. It provides a brighter alternative to dark gray while maintaining a neutral aesthetic. Light gray also reflects more light, which may help improve visibility in covered or low-light areas and reduce surface temperature in direct sunlight. It tends to conceal UV fading better than darker shades.

green

Commonly used in water treatment plants, parks, and other outdoor environments, green Fiberglass Grating blends naturally with landscaping and surrounding vegetation. As a result, it is frequently selected for municipal and environmental infrastructure projects. Green also offers moderate resistance to fading over time.

brown-orange

(Only available in select Fiberglass styles) This color is used in environments where a warmer, earth-toned appearance is desired. Brown-orange Fiberglass Grating complements industrial settings, utility infrastructure, and outdoor installations where blending with surrounding materials or terrain is desirable.

white

(Only available in select Fiberglass styles) White Fiberglass Grating offers a bright, clean appearance that enhances light reflection in indoor spaces. As a result, it is often selected for food processing areas, laboratories, and other facilities where visibility and cleanliness are important.

Surface Profile Options: Function Meets Form

In addition to color, it is important to consider the surface profile when selecting Fiberglass Grating, as it influences both function and appearance. The surface profile can affect slip resistance, comfort underfoot, and maintenance requirements. McNICHOLS offers two primary surface profiles designed to address different operational needs:

McNICHOLS® Fiberglass Grating, Molded, Square Grid, MS-S-100, Fiberglass, SGF Polyester Resin, Dark Gray, 1" Grid Height, 1-1/2" x 1-1/2" Square Grid, Grit Surface, 70% Open Area
ITEM F241111C31

1. Gritted Surface

Description: Embedded with coarse grit, this surface provides superior slip resistance, even in wet or oily conditions.

Best for: Industrial plants, food processing facilities, and marine environments where slip resistance is critical.

Maintenance: Easy to clean but may require periodic re-gritting in high-traffic environments.

McNICHOLS® Fiberglass Grating, Molded, Square Grid, MS-S-100, Fiberglass, SGF Polyester Resin, Dark Gray, 1" Grid Height, 1-1/2" x 1-1/2" Square Grid, Concave Surface, 70% Open Area
ITEM F241111W31

2. Concave Surface

Description: Features a slightly curved, smooth surface that channels liquids away and helps reduce pooling.

Best for: Environments where both slip resistance and easy cleaning are important, such as chemical plants and wastewater facilities.

Maintenance: Compared with gritted surfaces, concave profiles are less abrasive, making them more comfortable for frequent foot traffic.

Choosing the Right Combination

The best color and surface profile will depend on your project’s specific requirements:

  • For maximum safety: Opt for yellow with a gritted surface.
  • For public or architectural spaces: Select gray or green with a concave surface.
  • For outdoor or corrosive environments: Consider UV-resistant colors paired with a concave surface that promotes drainage and helps reduce standing water.

Conclusion

McNICHOLS® Fiberglass Grating offers a versatile solution for a wide range of applications, with color and surface profile playing important roles in performance and safety. By carefully considering both factors, you can improve safety, durability, and overall project appearance.
