Reliable - Very Large Area, greenhouse shelters

Redpath is New Zealand’s largest steel frame polythene clad greenhouse manufacturer with 16 installation crews nationwide and in Australasia.
The Redpath large area canopy shelter is used by outdoor crop farmers and orchardists seeking a reliable low maintenance yet cost-effective solution for their crop protection.
Redpath canopy shelters are design engineered with a 25 year minimum frame life and can be a simple 'roof-only' design or include a quality European mechanical rack & pinion fully automatic ridge vent opening systems. The design uses substantial  150 or 100mm x 50mm RHS section for its rafters, Folded steel 'walk through' gutter lines, and all 12mm + Nylock bolted connections offering long and durable service life.
The V.L.A design is offered in spans of 11.2, 12.2m, 13m, 14m and 15m.

Redpath large area canopy may be erected as a free-standing shelter over and above new areas or existing crops. Crops such as Blueberries, Passionfruit, Strawberry, Lettuce, Brassicas, Nashi, Avocado, Cherries, Kiwifruit, Pationfruit and many others 

The design uses the 215 micron clear Duratough cladding for the roof and has good resistance to wear and tear from wind and also excellent longevity against UV stress.  A further option is to fit the super heavy duty 260 micron Durashelter for a modest extra cose.
The Duratough and Durashelter cladding offer 90% + PAR light transmission (photosynthetic active light) benefiting crop growth, fruit quality and production, and foliage growth. 


The Redpath design provides a straight forward assembly process, with all the structural connections in the building being pre-drilled ex Redpaths factory. The full RHS heavy steel framework is simple, efficient and strong allowing owners or their contractors to erect the canopy themselves if they wish, however Redpath offer an installed price on site as standard which includes completion of building permit and full compliance engineering.
Redpath do not recommend erecting large areas of non-permeable roof cover without the appropriate permits and third party engineering cross-checks.


In hectare areas, with textile clad sidewall and a 4m gutter height the non-roof vented kitsets will often cost less than $37 + GST per m2 ex our factory
