Frequently Asked Questions
How do I determine the right thickness for my application?
Thickness selection depends primarily on load requirements and support spacing:
- Light foot traffic with 12″ support spacing: 1/4″ thickness typically sufficient
- Heavy equipment with 24″ support spacing: 1/2″ to 1″ thickness recommended
Always consult load tables or engineering specifications for your specific application.
Can fiberglass gritted plates be used outdoors?
Yes, fiberglass gritted plates are suitable for outdoor applications. They resist UV damage, temperature fluctuations, and weather exposure with minimal degradation. For optimal outdoor performance, specify UV-inhibited resin systems for extended color stability.
How do I clean fiberglass gritted plates?
Standard cleaning involves:
- Regular sweeping to remove debris
- Occasional washing with mild detergent and water
- Pressure washing (below 3000 psi) for stubborn dirt
- Avoid harsh abrasives that might damage the grit surface
Are there any environments where fiberglass gritted plates shouldn’t be used?
While versatile, consider alternatives in these situations:
- Environments with continuous temperatures above 300°F (149°C)
- Areas with direct exposure to open flames
- Applications requiring high point load capacity
- Locations with heavy abrasive particle exposure
How long will the anti-slip surface last?
With proper installation and maintenance, the anti-slip surface typically maintains effective slip resistance for the life of the product (long service life in many environments). High-traffic areas may show some wear after 15-20 years but generally remain within safe slip resistance parameters.
Can I get custom sizes or configurations?
Yes, custom fabrication is readily available:
- Non-standard dimensions
- Custom cutouts for equipment
- Special edge treatments
- Radius corners
- Integrated features like lifting handles or identification markers
