Walk In Tunnel

Walk in Tunnels are basically the protected structure made from galvanized pipe and covered with UV Stabilized Plastic Sheet. Generally Walk in Tunnels are used to give favorable controlled environment like temperature, humidity, light intensity, ventilation, soil media, disease control, irrigation, Fertigation and other agronomical practices throughout the season irrespective of the natural conditions outside. Walk In Tunnel have variety of applications, the majority being, growing of vegetables, floriculture, planting material acclimatization, fruit crop growing for export market.

In conventional Agronomical practices, the crops are being grown / cultivated in the open field under natural conditions where the crops are more susceptible to sudden changes in climate i.e. temperature, humidity, light intensity, photo period and other conditions due to which the quality, yield of a particular crop can get affected and may be decreased.

Walk in Tunnels are available in different sizes and constructed as per customer requirement.

Major Design Consideration

Galvanized Steel Construction.

Prefabricated structure which makes easy to assemble & dissemble.

Complete structure is assembled with Nut-bolts.

No welding is required.

Easy to Assembly and Maintenance.

Structure design to withstand wind speed of 120 km/hr.

Structure design to Trellising load of 25 kg/m².

Advantage of Walk In Tunnel

Trellising system for vegetable.

Reduction in labour cost.

Less chances of disease attack, thus reduction in disease control cost.

Less fertilizer requirement, thus reduction in fertilizer cost.

Uniform and better quality.

Cost of the structure is less than other protected structure.

Growing Crop under Walk in Tunnel
