What technical need does Graepel ColorGrip address?
With many colored powder coatings, the surface’s slip resistance decreases, particularly on predominantly solid surfaces. Conventional coating processes can therefore compromise the safe walkability of sheet metal components such as walkways, stair treads, and platforms.
Graepel ColorGrip was developed to enable colored surfaces without reducing safety-critical slip resistance. The coating ensures that color-coated sheet metal parts achieve at least the same slip resistance as a comparable hot-dip galvanized surface, or exceed it.
What is Graepel ColorGrip?
Graepel ColorGrip is a special powder coating applied to perforated sheets, profiled metal gratings, stair treads, and other safety components.
Unlike conventional paint coatings, ColorGrip does not negatively affect the surface roughness required for safety; rather, it maintains or improves it compared to hot-dip galvanized surfaces.
How does Graepel ColorGrip work?
Graepel ColorGrip is applied as a powder coating to the surface of sheet metal parts. The coating is formulated and applied in such a way that it:
- enables colored surfaces
- ensures or improves slip resistance compared to hot-dip galvanized surfaces
- creates safe walking surfaces even on predominantly solid or painted surfaces
Why is ColorGrip relevant for sheet metal parts and perforated sheets?
Walkways, stair treads, and landings made of sheet metal components must be designed to be permanently slip-resistant. At the same time, there is a growing demand for colored surfaces, for example for identification, design, or integration into a corporate identity.
Conventional paint coatings can alter the surface structure and thereby compromise slip resistance.
Graepel ColorGrip enables colored finishes on perforated sheets and other perforated sheet metal components without compromising safety-critical walkability.
Advantages at a glance:
- Colored-coated sheet metal parts with preserved slip resistance
- Slip resistance at least on par with hot-dip galvanized surfaces
- Suitable for walkways, stair treads, and platforms made of perforated sheet metal
- Combines functional safety with design freedom
Technical Specifications of ColorGrip
Graepel ColorGrip offers the following functional properties:
- Color-coated surfaces in customer-specified colors
- Maintenance or improvement of slip resistance compared to hot-dip galvanized surfaces
- Suitable for safety-critical sheet metal components such as walkways, stair treads, landings, and ladder rungs
- Applicable to perforated sheets, perforated plates, and profiled sheet gratings
The coating allows for visual customization of the surface without compromising safety-critical walkability. The slip resistance meets or exceeds that of comparable hot-dip galvanized products.
Typical applications of Graepel ColorGrip
- Safety gratings and walkways with color specifications
- Stair treads and ladder rungs in corporate or vehicle colors
- Landing platforms and platforms in industrial and vehicle manufacturing
- Color-contrasting safety surfaces or areas without compromising functionality
Economic Benefits of ColorGrip
Graepel ColorGrip enables:
- colored, safe surfaces without compromising on slip resistance
- Customization to match corporate design or color coding
- Reduced need for additional marking or safety measures
- greater acceptance and visibility in safety areas
- Thanks to the quality of the coating, maintenance requirements are reduced compared to multi-layer or improperly coated surface solutions.
Summary for Technical Decision-Makers
Graepel ColorGrip is a specialized coating solution for colored surfaces on sheet metal parts and safety-critical components made of perforated sheet metal and perforated plates. It combines visual design with functional slip resistance by maintaining or improving the safety-critical surface performance to at least the level of hot-dip galvanized gratings.
ColorGrip is particularly suitable for applications where colored marking, corporate design integration, or architectural design are required in conjunction with functional safety.
FAQ
Conventional paint coatings for sheet metal parts are primarily designed for corrosion protection and color. The slip resistance of the surface is generally not a defined development parameter.
Graepel ColorGrip was developed specifically for safety-critical applications. In addition to color design, the coating specifically addresses the slip-resistant function of the surface. As a result, the walkability of perforated sheets and other perforated sheet metal parts is maintained at least at the level of hot-dip galvanized versions.
ColorGrip can be used on perforated and embossed metal sheets and profiled metal gratings, particularly in areas where slip resistance is important. The specific application depends on the design and functional requirements.
Any color is possible, allowing for the creation of colored safety zones or corporate design solutions.
The coating is designed to provide functional safety and does not adversely affect service life. Specific service life indicators depend on the application, frequency of use, and environmental conditions.
