At Mwanga Solutions, we supply premium-grade Pultruded GRP Grating Walkway Panels, purpose-built for solar rooftop installations, industrial walkways, and elevated maintenance routes in Kenya’s commercial and renewable energy sectors.
Made using pultrusion technology, this grating type offers superior load-bearing capacity, enhanced UV resistance, chemical stability, and extreme durability. It’s the preferred choice for long linear spans such as solar panel walkways across industrial rooftops and high-stress platforms.
Perfect for rooftop solar mounting systems
Made for harsh Kenyan UV, rain, and wind conditions
Safer, lighter, and longer-lasting than steel or timber

Watch how these grating systems are installed, walked on, and integrated into solar platforms for Kenya’s rugged weather. See real-world use in rooftop solar projects and how anti-slip and load-bearing performance hold up under heavy traffic.
Q1: Can it support heavy equipment or foot traffic on solar rooftops?
Yes. With a proper support structure, it handles up to 9 tons/m² — ideal for rooftop tools, workers, and inspection carts.
Q2: What makes pultruded GRP better than molded FRP for walkways?
Pultruded GRP has higher stiffness, stronger longitudinal load capacity, and longer spans, making it perfect for linear rooftop applications.
Q3: Can I request specific dimensions to fit my solar panel layout?
Absolutely. Mwanga Solutions offers precision cutting and edge treatment at no extra charge for bulk orders.
Q4: Is it compliant with fire and safety codes?
Yes. Fire retardant resins are available and compliant with ASTM E84 standards.
Q5: How is it installed on corrugated or sheeted rooftops?
With adjustable mounting clamps or support brackets to avoid perforating the roofing sheet, preserving waterproofing.
