Aquaculture buildings

Aquaculture is a new and fast expanding intensive farming system, with these reticulated water/nutrient systems often housed in a Redpath shelter with natural light coming in through the clear or shaded roof cladding.

Redpath pay special attention to the corrosion resistance of poles and framing for Aquaculture sheds; otherwise seawater or high levels of humidity will take their toll on all parts in the sheds.

A range of spans is available for this application, with Redpath's open plan overhead designs allowing the installation of tall storage / growing tanks.
