Drainage Grates

Applications & Use Cases

• Industrial kitchens and food processing facilities require effective floor drainage to maintain hygiene and safety.
• Chemical processing plants utilise drainage grates to manage spills and washdown effluent.
• Warehouses and loading docks benefit from robust drainage to handle rainwater ingress and cleaning operations.
• Abattoirs and meat packing plants depend on efficient drainage for waste removal and sanitation.
• Breweries and beverage production sites use drainage systems to manage process water and cleaning solutions.

Typical Specifications

Typical material

Drainage grates for industrial use are commonly manufactured from stainless steel (grades 304 or 316) for corrosion resistance, or occasionally galvanised steel for general industrial applications.

Load bearing capacity

For this class of equipment, load ratings typically range from light pedestrian traffic to heavy forklift loads, often classified according to EN 124 standards (e.g., A15 to F900).

Common dimensions

Individual grates are commonly found in square or rectangular formats, with typical side lengths ranging from 100mm to 1000mm, designed to fit standard channel widths.

Surface finish

The surface finish can vary from plain bar grates to anti-slip patterns, depending on the required traction and hygiene standards for the specific application.

Drainage rate

The open area of the grate, and thus its drainage capacity, is determined by the bar spacing and overall design, typically specified in litres per second or cubic metres per hour for a given flow depth.

Installation type

Grates are typically designed for flush installation within floor channels, often with a recess for a secure fit and to prevent tripping hazards.

Frequently Asked Questions

• What should I consider when selecting the material for drainage grates?

  Material selection should primarily be based on the corrosive nature of the liquids handled, hygiene requirements, and the expected load. Stainless steel is preferred for food-grade and chemical environments, while galvanised steel suits less demanding industrial settings.

• How do I determine the correct load rating for my application?

• Are these grates suitable for high-hygiene environments?

• What maintenance is typically required for industrial drainage grates?

• Can these grates be used with existing drainage channels?
