Smart Industrial Multi Span Greenhouse For Vegetable Growing

Advantages

1. Hot-dip Galvanized Steel Structure, Stable and Durable
The greenhouse is constructed with high-strength hot-dip galvanized steel pipes. The thickness of the surface zinc layer is ≥275gsm. Its corrosion resistance is significantly better than that of ordinary steel materials, enabling it to adapt to complex environments such as humid, acidic and alkaline conditions. The service life can reach 10 to 15 years. The specially designed horizontal climbing rod is located at the shoulder of the greenhouse and is connected to the top through a suspension rod, forming a triangular truss structure. This not only enhances the overall wind resistance (able to withstand wind speeds below 90 km/h), but also provides support for the vines of crops to climb.
2. High Cost-effectiveness, Quick Return on Investment
By optimizing the specifications of the steel pipes and the combination of covering materials, the construction cost is only 60% to 70% of that of traditional greenhouses, which is especially suitable for small and medium-sized farmers at the initial investment stage. With the pre-assembled design of the accessories, 2 to 3 people can complete the construction of a 100-square-meter single-unit greenhouse within 1 to 2 days according to the illustrated manual, without the need for professional technicians. The galvanized snap connectors replace the welding process, avoiding the risk of rust and breakage. The standardized accessories can be quickly assembled with bolts, making the installation convenient and reliable.
3. Flexible Expansion, Adapting to Different Scales
The standard single-unit greenhouse has a width of 8 meters, and the length can be customized (ranging from 10 to 100 meters). It supports seamless upgrading from a single unit to a multi-span connected structure. In the initial stage, a single unit can meet the needs of small-scale planting. Later, through horizontal splicing, it can be expanded into a large-scale planting area, easily realizing the expansion of production scale.
4. Intelligent Drainage System, Water-saving and Efficient
The U-shaped galvanized drainage trough has a slope of 2.5‰ - 5‰, which can increase the drainage efficiency by 40% during heavy rain to prevent waterlogging. The supporting rainwater collection system can be connected to water storage buckets or underground cisterns, saving an average of 20% to 30% of water annually, making it suitable for water-scarce areas. The EPDM sealing strips are used at the joints to ensure long-term leakage prevention and no deformation.
5. Multi-functional Covering Solutions, Coping with Changing Climates
Agricultural Film: It is recommended to use a film with a thickness of 150-200 microns. The light transmittance is ≥90%, and it has both heat preservation and anti-ultraviolet functions.
Insect-proof Net: A 30-60 mesh nylon net is used to physically block pests such as aphids and whiteflies, reducing the use of pesticides.
Sunshade Net: You can choose a silver aluminum foil sunshade net or a black sunshade net with a shading rate of 30% - 80%. It can reduce the temperature inside the shed by 5-8℃ in summer.
6. Natural Ventilation Design
Manual rolling windows are installed on the top and around the greenhouse. The opening height of the windows can reach 2 meters, and insect-proof nets are equipped to achieve efficient ventilation. When it is hot, open the windows to cool down, and close them at night to keep warm, taking into account energy conservation and the growth needs of crops.
