The Multispan Polytunnel is engineered for commercial growers who need maximum growing area under one connected structure. Multiple bays are joined with shared gutters to create a continuous covered environment, giving you the scale of a glasshouse with the cost efficiency of a tunnelhouse.
Single-bay tunnelhouses have limits. Once you need more growing area, connecting multiple structures with shared gutters gives you uninterrupted floor space, simpler crop management and better climate control across the whole site. The Multispan Polytunnel is designed for operations running vegetable production, cut flowers, propagation or nursery stock at commercial scale.
Australia's climate is unforgiving. Heat, hail, storms and wind all take their toll on protected cropping structures. The Multispan Polytunnel uses galvanised steel frames and premium commercial-grade covers, engineered to hold up through the conditions that bring lesser structures down. Options for roof vents, roll-up sides, twinskin covers and gutter upgrades let you configure the structure for your climate and your crops.
EnviroTec manufactures every Multispan Polytunnel at our Yandina facility on the Sunshine Coast. Frames are cut, drilled, bent and rolled in-house, drawing on 40 years of experience building commercial greenhouse structures. Structures we built in the 1990s are still operational today. Available fully installed by our team, with site assessment and project management included.

Multispan design gives you uninterrupted growing area across multiple connected bays. You get the scale commercial production demands without the cost or complexity of a full glasshouse build, plus the climate control benefits of a single shared environment rather than separate structures working against each other.
