An investigation into the suitability of fibre reinforced plastic roofing for New Zealand dairy processing plants

Abstract

This report is a preliminary investigation into the feasibility of the use of fibre reinforced plastic (FRP) as a lightly loaded long-span structural roofing system for use on dairy processing plants within New Zealand. The conditions associated with dairy production plants in New Zealand are discussed to identify the hygiene, functional and planning requirements. The internal environmental and chemical conditions are investigated as they specifically relate to the roof of a generic dairy processing plant. This study continues with an outline of the opportunities and limitations presented by the use of FRP as a material for lightly loaded long-span structural roofing in the New Zealand context. The information gathered is then analyzed to relate the use of FRP to the specific requirements and conditions associated with a roof for a generic New Zealand dairy processing plant. Possible options for the use of FRP including its, composition, manufacturing method, form, fixing, jointing and use are discussed. Aspects of long-span structural FRP design that require special consideration in the context of New Zealand dairy processing plant roofing are also stated. The report concludes with an overview of the outcomes of the research and lists recommendations for further research.
