The latest construction made by Agro-Sur is a film tunnel with a width of 25m. The onion-shaped tunnel is a structure made of welded steel trusses. The structure of the facility is fully protected against harmful corrosive conditions. This innovative facility, fully compliant with the requirements of the PN-EN ISO 1090 standard, confirmed by the CE mark, was built by our company at the request of the Lithuanian Forest District for the purpose of seedling cultivation. The system of top two-sided ventilation and a two-layer inflated film allow for optimal climatic conditions for plant cultivation. The structure of the facility was designed and made from scratch in our company. Due to its internal space, the facility has an enormous logistics and production capacity.
