Food & Beverage FRP Grating
Food & beverage FRP grating gives processing plants a non-porous, easy-clean, anti-slip floor and walkway that survives caustic washdown, brine, steam and wet production areas without the rust and harbouring bacteria of steel.
Food-grade FRP grating is used on processing-room floors, drain covers, mezzanine walkways, platform stairs and cable trench covers in dairy, brewery, meat, seafood, beverage and prepared-food plants. Stainless steel floors are expensive and slippery; galvanized steel corrodes under daily caustic and acid washdown; wood absorbs moisture and harbour bacteria. FRP panels are non-porous, do not support bacterial growth, rinse clean and resist the cleaning chemicals used in the food industry.
Panels are specified with a grit-top or covered surface where wet, oily or greasy foot traffic must stay safe, and in mini-mesh 12×12 mm where tools or small product must not fall through. Isophthalic polyester is the standard system for washdown areas; vinyl ester is selected for dairy CIP and aggressive brine or chemical exposure. Panels are cut and fabricated to the plant drawing with rounded edges and smooth transitions to avoid product traps, and fixed with stainless clips — no open welding spatter in the food zone.
Food & Beverage FRP Grating — Specifications
| Parameter | Molded Grating | Pultruded Grating |
|---|---|---|
| Panel thickness | 25 / 30 / 38 mm | 38 / 50 mm (I-bar) |
| Mesh / bar spacing | 38×38 / 19×19 / 12×12 mm mini | 38×38 mm |
| Standard panel size | 1220×3660 mm | 1220×3660 mm |
| Surface | Grit-top / Covered solid / Concave | Grit-top |
| Resin system | Isophthalic (standard) / Vinyl Ester (CIP) | Isophthalic / Vinyl Ester |
| Hygiene | Non-porous, easy rinse, no bacterial harbour | Non-porous, easy rinse |

Resin & Material Selection
| Resin | Role | Best Environment | Fire Rating |
|---|---|---|---|
| Isophthalic polyester | Standard | General washdown, dairy, beverage, meat processing | ASTM E-84 Class B |
| Vinyl ester | Recommended for CIP | Dairy CIP, brine, aggressive cleaning chemicals | ASTM E-84 Class B |
| Covered solid panel | Hygiene option | Where product must not fall through floor openings | ASTM E-84 Class B |
For caustic and acidic washdown and dairy CIP cycles, vinyl ester gives the best chemical resistance. Surfaces are rinsed clean with the standard sanitation hose — no special cleaning agents required.
Applications and Project Experience
Processing-room floors and drains: grit-top 30–38 mm panels over floor trenches and drainage channels, anti-slip under wet production and washdown.
Beverage and dairy lines: covered or mini-mesh panels around fillers and pasteurisers where spills, steam and CIP splash are continuous.
Seafood and meat areas: corrosion-proof panels over brine rooms and cutting lines, immune to salt and blood-and-fat washdown.
Mezzanine walkways and platform stairs: light, two-person-handled panels on raised walkways and stair treads, see stair tread grating.
Span and Support Spacing
Recommended maximum support spacing (deflection-limited, typical indicative values):
| Thickness | Type | Max Support Spacing | Typical Duty |
|---|---|---|---|
| 25 mm | Molded | 450 – 600 mm | Light walkways, trench covers |
| 30 mm | Molded | 600 mm | Processing floors, general pedestrian |
| 38 mm | Molded | 750 mm | Forklift / pallet-truck light traffic |
| 38–50 mm | Pultruded | 900 – 1200 mm | Mezzanines, long raised spans |
