Solar FRP Grating
Lightweight FRP walkways for solar farms, rooftop PV arrays and service routes — UV-stable, corrosion-proof, and gentle on roof membranes and mounting structures, with anti-slip footing for panel cleaning and inspection crews.
Solar FRP grating provides the maintenance walkways that large PV plants need: a safe, dedicated path across arrays so cleaning and inspection crews do not walk on and damage panels. Because FRP is roughly one quarter the weight of steel, rooftop and carport installations add almost no dead load to the structure, and panels can be carried and cut by hand. The resin system includes UV inhibitors for long outdoor exposure, and the non-conductive material is safe near DC cabling and inverters. Grit-top surfaces give wet-foot security after cleaning cycles. Walkways typically use 25–38 mm molded panels on steel or aluminum purlins, fixed with non-magnetic stainless clips so they do not introduce galvanic corrosion at aluminum mounting points.
Typical Solar-Grade Specification (Indicative)
Typical Solar FRP Grating specification below. Send your drawing and our engineers will confirm the section for your load and span.
| Parameter | Molded Solar Walkway | Pultruded Solar Walkway |
| Panel thickness | 25 / 30 / 38 mm | 38 / 50 mm (I-bar) |
| Mesh / bar spacing | 38×38 / 19×19 mm | 38×38 mm |
| Resin system | Isophthalic (UV-stabilized) | Isophthalic / Vinyl Ester |
| Anti-slip surface | Grit-top / Concave | Grit-top |
| Relative weight vs steel | ≈ 1/4 | ≈ 1/4 |
All figures are typical/indicative ranges for engineering reference; final section, deflection and clip layout are confirmed against your actual span and loading.
Field Applications and Project Use
Common solar PV applications:
Rooftop PV maintenance walkways: Ultra-lightweight 25–30 mm paths over roof membranes and ballasted arrays, protecting waterproofing from foot traffic and cleaning equipment.
Utility-scale solar farm access: Dedicated 38 mm grit-top walkways between panel rows for cleaning crews, string inverters and junction-box inspection.
Solar carports and canopies: Non-conductive, low-dead-load flooring under and around carport structures, safe near EV charging and DC cabling.
Tracking-system service routes: Walkways alongside single-axis trackers for lubrication, sensor checks and hydraulic maintenance access.
Inverter and transformer pads: Non-conductive grating around central inverters, transformers and combiner boxes.
Indicative Support Spacing for Solar Walkways
Recommended maximum support spacing (deflection-limited, indicative):
| Panel | Type | Max Support Spacing | Typical Duty |
| 25 mm | Molded | 450 – 600 mm | Rooftop pedestrian walkway |
| 30 mm | Molded | 600 mm | Rooftop + cleaning equipment |
| 38 mm | Molded | 750 mm | Solar-farm access roads |
| 38–50 mm | Pultruded | 900 – 1200 mm | Long-span service routes |
