Flooring for a farrowing crate particularly for pigs is formed of beams and support flanges which are manufactured of glass fiber reinforced resin so as to be electrically insulting. The beams span a pit for receiving manure. On top of the supporting structure is provided a flooring formed of a plurality of rectangular panels or tiles arranged side to side and edge to edge to form an array of the panels. An area under the sow is defined of pressure molded aluminum panels and an area fully surrounding an island of aluminum panels is defined by panels of injection molded plastics which are again relativ ely non-conductive. The steel structure of the farrowing crate is bolted to the plas tics panels at positions forwardly and rearwardly of the island of aluminum panels. Thus the aluminum panels are electrically insulated from any electrically conductive element within the farrowing crate to prevent galvanic corrosion of t he aluminum panels.
