400mm x 3660mm FRP Grating for Solar Power Panels Roof Top Walkways – Long-Lasting Safety and Strength for Elevated Access- Engineered for Safe, Non-Slip, and Maintenance-Free Rooftop Operations Mwanga Solutions introduces the 400mm x 3660mm FRP (Fiber Reinforced Plastic) Grating,...
Mwanga Solutions introduces the 400mm x 3660mm FRP (Fiber Reinforced Plastic) Grating, purpose-built for elevated rooftop solar panel installations in Kenya and across East Africa. This grating offers long-term performance in corrosive, wet, and UV-exposed environments, making it an ideal anti-slip access solution for solar power walkways.
Whether you’re managing rooftop inspections, cleaning solar panels, or ensuring safety on metal and concrete roofs, this molded FRP grating is the trusted solution. Its industrial-grade strength, fire resistance, and lightweight design make it ideal for solar developers, contractors, and facility managers.

| Step | Description |
|---|---|
| 1 | Site Survey: Measure roof pitch, support rails, and solar array layout |
| 2 | Support Framing: Install substructure using aluminum/steel angle brackets or FRP supports |
| 3 | Grating Placement: Lay grating panels across support purlins or structure |
| 4 | Fixing Method: Use SS304/FRP clamps to anchor panels without penetrating roof sheets |
| 5 | Joining Panels: Overlap gratings slightly and secure using FRP tie clamps or metal brackets |
| 6 | Edge Trimming: Cut panels on-site to allow roof features like vents, cables, or skylights |
| 7 | Safety Check: Confirm panel alignment, fixing tightness, and access clearance |

Mwanga Solutions works with solar EPCs, maintenance teams, and government facilities to provide grating options tailored for:
Corrugated iron rooftops
Kibanda metal sheet structures
High-rise office block rooftops
Concrete slab rooftops with drainage outlets
Steel truss framing walkways
Panel sizes can be pre-cut or field-trimmed for irregular or multi-level installations. Support rails and fixing systems are available locally.
Can I install this walkway without drilling the roof?
Yes. The FRP panels are clamp-fixed to structural frames or solar rails—no penetrations are needed.
Will the gritted surface wear out?
No. The anti-slip quartz grit is embedded during the molding process and lasts through years of foot traffic.
Can this grating be walked on in heavy rain?
Absolutely. The texture ensures full foot grip even during rainfall or morning dew.
Does it heat up in direct sun?
FRP has lower thermal conductivity than metals and stays relatively cool even under solar radiation.
What if I need a custom size?
We can cut to size before delivery or guide you through safe cutting during installation.
Is this walkway fire safe?
Yes. The product meets ASTM E84 Class 1 fire safety ratings and will not support combustion.
