Frames of Multi-Span Greenhouse
Features of glass or PC pannel multi-span greenhouse frame
The glass / PC pannel Multi-Span Greenhouse is modern in appearance, novel and stable in structure. The greenhouse is made of hot galvanized pipe, hot galvanized anticorrosive bolt and tapping nail. It has no welding point, it is solid, practical, simple and beatiful as a whole.
Glass or sunshine panels are used as covering materials for greenhouse, which have high transmittance and good thermal insulation. Large span spire design, large indoor operation space, high greenhouse utilization rate, good display effect. It can be used as large ornamental greenhouse, nursery greenhouse, flower greenhouse.
The technical parameters of General Design
Wind load: 0.5 KN/m2, Snow Load: 0.5K/m2, Greenhouse constant load: 15kg/m2, Greenhouse maximum displacement of rainfall: 140 mm/h.

Features of Multi-span film greenhouse
The greenhouse is an economic greenhouse, which is popular with users for its beatiful arc shape and low cost. The curved roofis beautiful and graceful, and the line of sight is smooth. Steel consumption in structure is less, and thermal insulation performance is better.
Greenhouse materials
The main structure of greenhouse adopts hot-dip galvanized pipe, which is connected by hot-di galvanized bolts and has good Corrosion Resistance.
Main body configuration
It can be equipped with internal and external sunshade, seedbed skylight side ventilation, water curtain, fan cooling facilities as requirement.
The life of the equipment
Therman body can be used more than 15 years, and the film is replaced once 3-5 years.
Covering material
The top of the greenhouse is covered with 15 filaments of PO film or crystal film. The outer layer is anti-ultraviolet and the inner layer is anti-condesation. The walls around the greenhouse are covered with 15 filaments of PO film, crystal film or sunshine plate. The walls around the greenhouse can also be changed as user’s requirements.
General design technical parameters
Wind load: 0.4KN/m2; Snow load: 0.35KN/m2; Greenhouse constant load: 10KG/m2
Maximum drainage rainfall: 140 mm/H; Hanging load: 15kg/m2.
Specific specifications and sizes are shown in the table below
| Greenhouse types/parameters | Span (m) | Bay (m) | Eaves height (m) | Ridgeheihgt (m) |
|---|---|---|---|---|
| Film multi-span greenhouse | 8.0 – 10.0 | 4.0 – 5.0 | 3.5 – 4.5 | 5 – 6 |
Note: the eaves height can be changed as user’s requirements.
Arch-shape greenhouse skeleton characteristics
Arched greenhouse is also known as cold shed or bread shed. Its top is curved, easy to construct and disassemble, and economic. It can be used as planting and breeding shed in spring, summer and autumn in southern and Northern China. In northern China, arch greenhouse and winter-warm greenhouse have a slightly lower performance, and can add two or three films in the greenhouse to increase night temperature. The spacing between girders and frames is generally about 1 meter, the construction span is generally between 6 and 8 meters, the construction height is about 3 meters, the utilization ratio is high, and the specifications are unified. It is convenient for mechanized tillage and suitable for planting in spring, summer and autumn in southern China and northern China.
Greenhouses
The intended use of the greenhouse determines the type, size and quantities of greenhouses. Critical factors affecting greenhouse selection are cost, use of greenhouse (vegetables, fruits, flowers or cannabis), and location of the greenhouse. Every greenhouse comprises of four essential elements: (1)- Framework, (2)-Cover, (3)- End wall & door, and (4)- Connectors & Fasteners. All our greenhouses are made of hot-dip galvanized light steel with lifetime of greater than 15 years. The greenhouse can be covered with single or multiple layers of Plastic Film (PE), Polycarbonate sheets (PC), or Tampered Glass. The end doors can be sliding or push-pull doors. Greenhouses are usually classified in two broader segments (1)- Freestanding Tunnels greenhouses that include Arch type (semicircle) and Gothic type tunnel greenhouses (gable), and (2) – Gutter Connected multi-tunnel greenhouses that include Arch type, Venlo type, and Sawtooth type tunnel greenhouses. All greenhouses are their pro’s and con’s and one must do the due-diligence which greenhouse is suitable for your application. Beside, the environment control system, supplementary lighting and light deprivation system, fertigation & control are essential parts of a successful greenhouse operations.
