FRP Grating Case Study | Brewery Brewhouse & Cellar Floor — ZeAllgrate

A craft brewery required new flooring for its brewhouse and fermentation cellar, where daily caustic clean-in-place (CIP) washdown, spilled wort and condensation from cold fermentation tanks created a continuously wet, corrosive environment. The previous epoxy-coated concrete floor had deteriorated within 2 years: coating blistered under caustic CIP solution, concrete spalled around the drainage trenches, and spilled wort on the horizontal surface created recurring slip hazards and fermentation of stray yeast. The brewery needed a hygienic, slip-resistant surface that would drain quickly and withstand daily caustic washdown without blistering.

Engineering specified FDA-grade vinyl ester molded grating over the drainage trenches, with mini-mesh in the tank aisles (where small fittings must not fall through) and standard mesh in open walkways. Client identity is kept confidential; the project is described as Confidential Client, a regional craft brewery.

ZeAllgrate supplied 340 m² of FDA-grade vinyl ester molded grating, with mini-mesh 19×19 mm panels in the tank aisles and standard 38×38 mm mesh in general walkways. All panels were post-cured and washed before dispatch, and delivered with food-contact compliance documentation. FRP flat-bar edge banding was factory-bonded to exposed panel edges so there is no open cut edge that could harbor yeast or bacteria. The smooth surface in tank aisles hoses clean without trapping wort residue; the grit-top walkways handle the continuously wet floor between brewhouse and cellar.

Installation was completed over the brewery's annual two-week production stop, with panels clip-mounted over existing trench frames using SS316 hardware. The open mesh drains wort and CIP solution straight to the trench below, eliminating standing puddles that previously bred stray yeast.
