Plastic Covers


We have a comprehensive range of silage covers to maximise the quality of your silage.

Silage covers are designed to help maximise silage quality by helping to exclude as much air as possible.

Our covers are high performance and are suitable for Australian conditions. Latest research shows that by using multiple layer covering systems such as the Top Deck.

System, utilising transparent Rhinotec as the underlayer, then a standard pit cover, topped off with the Zilltec woven protective covers, silage quality will be maximised, losses minimised and damage to covers, and the work load much reduced.
