Our greenhouse growing benches are manufactured using Galvalume galvanized steel, a premium material known for its exceptional resistance to corrosion and wear. With a lifespan of over 40 years, these benches withstand daily irrigation, high humidity and commercial-scale production without degradation.
Every greenhouse is unique. That’s why our bench systems can be adapted to your exact needs:
Standard or custom dimensions
Choice of irrigation trays
Fixed, rolling or fully mobile systems
Optional automation for movement
Integration with your existing greenhouse layout
We design benches that align with your crop type, operational workflow and available space.
Our benches are engineered to maximize growing area while ensuring smooth movement for workers. With rolling or mobile options, you can eliminate unused aisle space, increasing your production surface by up to 30%.
All benches are designed to improve ergonomics and reduce physical strain. Workers benefit from a comfortable height that supports efficiency during seeding, transplanting, trimming and harvesting.
