Mining FRP Grating
Heavy-duty fiberglass grating for mine sites, concentrator plants and ore-handling areas — corrosion-proof against acids, slurries and dust, anti-slip underfoot, and light enough for safe two-person handling at remote sites.
Mining FRP grating replaces steel and timber flooring in environments where both fail fast: acid mine drainage, wet ore, abrasive slurries and salt-laden process water eat through painted steel within a few years, while timber rots and becomes slippery. FRP (fiberglass reinforced plastic) grating is inert to these conditions, non-conductive and non-sparking, and carries pedestrian plus light maintenance loads on walkways, platforms and stair treads. Vinyl ester resin is specified for leaching and acidic service; isophthalic polyester for general dry and wet mining areas. Grit-top or concave surfaces keep foot traffic safe under wet, dusty and muddy conditions. Panels are cut to your layout with pre-drilled penetrations and fixed with stainless steel clips — no welding, no hot work on site.
Typical Mining-Grade Specification (Indicative)
Typical Mining FRP Grating specification below. Send your drawing and our engineers will confirm the section for your load and span.
| Parameter | Molded Mining Grating | Pultruded Mining Grating |
| Panel thickness | 38 / 50 mm | 50 / 75 mm (I-bar) |
| Mesh / bar spacing | 38×38 / 19×19 mm | 38×38 mm |
| Resin system | Vinyl Ester / Isophthalic | Vinyl Ester / Isophthalic |
| Anti-slip surface | Grit-top / Concave | Grit-top |
| Typical load class | B – C | C – D |
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 mining and mineral-processing applications:
Mine access walkways and stair treads: Grit-top 38 mm vinyl ester panels on access ramps and tower stairways — anti-slip in wet, muddy service and immune to acid drainage.
Concentrator / processing platforms: Corrosion-proof grating around mills, screens and flotation cells where process water and reagents are aggressive.
Ore loading and conveyor galleries: Non-sparking, non-conductive flooring along transfer points and conveyor walkways.
Heap leach and acid areas: Vinyl ester grating over leach pads, piping galleries and pump stations exposed to sulfuric acid and ore slurries.
Tailings and slurry pump stations: Walkways and covers around thickeners, tailings lines and pump rooms — no rust staining, low maintenance shutdowns.
Indicative Support Spacing for Mining Walkways
Recommended maximum support spacing (deflection-limited, indicative):
| Panel | Type | Max Support Spacing | Typical Duty |
| 38 mm | Molded | 600 – 750 mm | Pedestrian access |
| 50 mm | Molded | 750 – 900 mm | Maintenance + tool loads |
| 50–75 mm | Pultruded | 900 – 1200 mm | Heavy platforms, long spans |
