Product Description
Introducing the most cost-effective automated retractable rain shelter system designed with superior heat retention capabilities! This low-cost solution offers rapid protection for hectares or acres within minutes against rain, dew, hail, extreme cold, heat, and wind. Its climate optimization and extreme weather protection address 10 of the most significant challenges faced by outdoor crop growers who occasionally require protection.

1. Safeguard your yields and ensure top-notch quality by expertly managing rain, dew, hail, cold, heat, or wind conditions.
The market
2. Strategically time your harvests to enter more profitable market windows.
3. Consistently meet and exceed your buyers' ever-evolving quality expectations.
Labor
4. Navigate the challenging labor market by significantly reducing labor needs: • Minimize labor for spraying and moving roofs • Enhance harvest efficiencies for a leaner operation.
5. Lessen the reliance on agricultural chemicals by optimizing the growing environment, aiding compliance with restricted chemical approvals.
6. Circumvent local governmental regulations restricting permanent greenhouse constructions: a) Install the Roof house on augers to avoid permanent building classification. (Concrete gable bracing is strongly advised) b) Utilize solar panels or generators to power the Roof house, eliminating grid connection needs. c) Efficiently redirect water away from crops to the ground, potentially removing the requirement for stormwater management plans.





7. Protect remote fields or orchards with portable power supplies or solar panels equipped with battery storage for powering the Roof house. A mere 2-3 kWh of electricity is sufficient per hectare per day.
8. Abolish labor requirements and expedite response times since traditional manual rain shelters cannot be easily or swiftly opened or closed.
9. Avert heat and humidity accumulation typical in conventional tunnels.
10. The Roof house represents a more affordable retractable roof solution within the JULONG portfolio, ideal for crops needing intermittent protection like cherries, grapes, kiwi fruit, berries, or outdoor flowering crops.





Ideal crops and applications | Crops typically grown in the outdoors or under traditional rain shelters, hail nets or in tunnels such as tree fruits like cherries, vine crops like grapes and kiwi fruit, berries, vegetables and outdoor flowering and nursery crops. Crops must be able to tolerate rain falling to the ground at the valleys |
Gutter to collect rain | No. Rainwater will fall on the ground at the valleys causing increasing soil wetness, chilling of the soil and soil erosion. RH inside will increase after rain if the roof is closed to increase temperatures |
Roof covering | 150 gms/m² woven polyethylene clear |
Closing time of roof | 4-6 minutes depend on roof treavel |
Roof covering service time | 3-7 YEARS |
House widths | 4-6m |
can support a hanging crop | no |
Maximum wind speed assuming roof covers and walls are closed: kph (mph) | 100(60)(based on 4m wide house) |









1. Durable stainless steel cables, galvanized coated cables, and robust bearings ensure long-term, trouble-free operation.
2. A secure peak connection minimizes rain penetration, while a tight valley closure enhances heat retention-bringing harvests forward with warmer spring temperatures and better frost protection.
3. Retracting covers before severe winds can arrive helps protect the cover and structure from potential damage.
4. This structure offers installation flexibility using concrete or screw-in augers. Concrete is highly recommended for gable bracing anchors, especially in challenging soil conditions, to stabilize the drive system.
