TELESCOPIC TUNNEL

Product catalog summary

Introduction to Telescopic Tunnel
The Telescopic Tunnel is a specially designed polytunnel aimed at extending the growing season. Its unique feature allows the entire structure to be lowered for early crop establishment and raised to increase air volume for main season production. This adjustability minimizes labor costs as the canopy can be raised and lowered with the polythene in place.

Material Specifications
High Strength Oval (HSO) Steel: The tunnel utilizes HSO steel, which is oval-shaped to enhance structural strength where needed most. This design increases hoop strength, preventing deformation from wind, hail, or snow. HSO steel is available in two sizes, HSO 80 and HSO 60, with the choice depending on the specific climatic conditions of the site. Haygrove HSO steel is noted for its high strength and excellent value.

Design Features
Telescopic Legs: The telescopic feature offers maximum flexibility, allowing the tunnel to be adjusted to create the optimal growing environment. When raised, it increases air volume, stabilizing the internal environment and reducing humidity, which can lead to higher yields and better-quality fruit. In the lowered position, it provides a seal that forces crop earliness, giving access to early season markets and extending the production season.

Full-width Roller Doors: These doors enable early production to capture early season market prices. They protect crops from wind and adverse weather, ensuring optimal growth conditions. The roller doors can be operated mechanically or electrically, offering flexibility and full access for machinery.

Conclusion
The Telescopic Tunnel combines the benefits of flexibility and strength, making it an ideal choice for growers looking to optimize their production throughout the season.

Catalog excerpts

telescopic tunnel The Telescopic tunnel is a uniquely designed polytunnel for season extension. The whole structure can be lowered to benefit from early season crop establishment, and then raised to increase air volume for main season production. The canopy can be raised and lowered with the polythene in situ, minimising labour cost. High Strength Oval (HSOtm) steel HSO steel is a smart way to add strength to your tunnel structure. The oval shape of the steel adds strength to the tunnel where it’s most needed. HSO steel gives the ability to increase hoop strength and prevent it from deforming under loading from wind, hail or snow. HSO steel is available in 2 sizes: HSO 80 and HSO 60. The steel choice most suitable for your tunnel will be determined by the climatic conditions of your specific site. Haygrove HSO steel is the premium steel choice for growers seeking high strength and excellent value for money. hoop profile GOTHIC
