Aquaculture buildings

Redpath Aquaculture shelters with roofing type can be clear open UV  or seaweed, algae growth or white shaded to reduce UV stress for shellfish etc.
Redpath Aquaculture shelters provide a natural and environment for quality and consistent fish farming production.

Redpath pay special attention to the corrosion resistance of the poles and framing and can also up-spec the building for even greater resistance to saltwater environments.

A range of spans is available for this application, from 6m wide right through to 15m clear spans.
Roll up wall blinds and roof ventilation systems with fully automated or manual control are optional for ventilation throughout the season, Or alternatively an extraction fan system may be easily fitted.
Overhead shade screen systems are another popular choice for Aquaculture applications.

Redpath operates 16 construction teams, we manage the building permit application and can help with resource consents if they arise. We then build on your site using local builders that then continue to offer local after sales service. Redpath have supplied and erected 1000s of these designs throughout our nearly 40 year history. A full set of registered engineers drawings and Producers statement for council building permit processing are included as standard
