Three decades of getting it right in the field.
At Agrotech, we exist to make protected cropping simpler, more dependable and more productive. For more than three decades we've worked side by side with commercial growers to design, supply and support tunnel systems that perform in the real world, season after season.
Every tunnel we build combines smart engineering with field validation and grower collaboration. Strength, functionality and ease of use are tested, not assumed, before they ever reach your site.

Engineered Span Performance
Structure That Doesn't Cut Corners
Wider tunnel spans, high-strength oval steel and a Y-leg support system, engineered for level, sloping or uneven sites, and built for clear access for tractors, trolleys and everyday farm equipment.
Generous internal height and growing space
Improved natural airflow and ventilation
Customisable width, height and tunnel length
Suitable for level, sloping or uneven sites
Clear access for tractors and farm equipment
Compatible with irrigation and crop-support systems
Y-Leg Support System
A wishbone-style leg spreads load evenly across the frame, keeping the structure stable on level, sloping or uneven ground without extra bracing.
Leg height matched to crop & access needs
Built for mechanised, automated venting
Buffers day-to-night temperature swings
Retractable shade systems, when required
Structural Profile
80 × 40mm
High-strength oval steel, optimised for robust commercial framing and wider-span layouts.
60 × 40mm
A lighter oval profile for standard-duty spans, keeping material use efficient without giving up strength.
Roof Profile
HighSpan Round. A classic arched roof structure, suited to a wide range of crops and conditions.
HighSpan Gothic. Introduces a higher peak for improved runoff, ideal where rainfall shedding matters.
HighSpan Gothic Plus. Steeper shoulders and additional internal clearance, for taller crops and equipment access.
Support Leg Height
2.75m
Standard
Balanced height for general cropping.
4.00m
Extended
Added clearance for access and venting.

Mechanised Venting
Vent at the Right Moment, Every Time.
EZvent allows you to vent at the optimal moments and with sufficient frequency to maximise yield, whilst minimising labour bills.

Reduction in fruit wastage from the leg rows, seen by growers using automated venting.
5% yield lift
A 5% increase in yield on a 60t/ha strawberry crop equals an additional 3t/ha, roughly a 3–4 year payback on a venting system investment.
Smart, Automated Control
Mechanical chain drive or fully automated with climate sensors, EZvent's patented design keeps installation time and cost low.
