Mining & Metals
Why Mining & Metals Needs FRP
Mining and smelting combine heavy loads, abrasive slurries, acids and heat. Steel grating fails through corrosion; FRP — with pultruded stiffness for heavy loads and molded flexibility for impact — delivers the service life the industry demands.- Acidic process liquors and leaching reagents
- Abrasive slurry exposure
- Heavy dynamic loads on walkways
- High-temperature process areas
ZeAllgrate Solutions for Mining & Metals
ZeAllgrate pultruded grating carries heavy loads over long spans, while molded grating absorbs impact in high-traffic zones — with resin systems matched to leach chemistry.
Typical Applications
Electrowinning plant walkways
Slurry channel covers
Leach tank platforms
Concentrator access decks
Smelter maintenance platforms
Flotation plant walkways

Technical Specifications & Compliance
Application-specific engineering reference for Mining & Metals — corrosion rating, load criteria, governing codes and the recommended ZeAllgrate configuration. Use this as the specification starting point; final design must be verified against certified load/span charts and the project's governing codes.
| Parameter | Specification for Mining & Metals |
|---|---|
| Corrosion Level | Severe Acidic leach liquors, abrasive slurries, electrowinning electrolytes and elevated process temperatures. |
| Typical Load Requirements | Heavy-duty — 100–200 psf (4.8–9.6 kN/m²) on concentrator & smelter decks; dynamic loads from haul trucks & forklifts on designated routes; point loads for agitator drives. |
| Applicable Standards & Regulations | MSHA (Mine Safety & Health Administration) metal/non-metal standards, OSHA 1910.29, ISO 14122, ASTM E84, GB/T (China) where domestic Chinese mines specify. |
| Recommended Resin System | ZeAll VE for acid leach, SX/EW and electrolytic cells; ZeAll ISO for general concentrator & maintenance areas; temperature-limited where process heat exceeds resin HDT. |
| Recommended Grating Type | Pultruded I6015/T5020 heavy-bar for long-span, high-load walkways; Molded 50.8 mm (HLC) for impact-prone flotation & crushing zones; solid covers for slurry channels. |
Resin systems: ZeAll VE (vinyl ester — severe corrosion), ZeAll ISO (isophthalic polyester — general service), ZeAll FDA (food/potable grade), ZeAll FR (extra flame-retardant), Phenolic (fire/smoke-critical). Grating types: Molded (bi-directional), Pultruded (long-span), Mini-Mesh (fine openings), HLC (high-load capacity).
Mining Service Requirements
| Condition | ZeAllgrate Response |
|---|---|
| Acid leach & electrowinning | Vinyl ester for strong acid contact |
| Heavy concentrated loads | Pultruded sections / high-load molded |
| Wet, muddy traffic | Grit-top surfaces |
| Slurry & channel service | Corrosion-proof covers and liners |
Specification Guidance
Mines and metal plants concentrate the corrosive load: electrowinning decks sit over strong acid, leach tanks and slurry channels attack the structure, and concentrated loads arrive on foot and machinery. Specify vinyl ester for the acid zones, pultruded grating for long spans and high stiffness, grit-top where the deck is wet and muddy, and SS316 hardware throughout. The case library documents leaching and electrowinning walkway installations with the resin decision recorded.
