New Type Of Tunnel Greenhouse For Vegetables

Translucent PVC film - Meet Solar Light at All Seasons

Light transmittance rate changes with roof covering material transmission properties and greenhouse skeleton shadow rate accompanied with a different angle of solar radiation in different seasons, the transmittance property of greenhouse can change within a great scope . The level of greenhouse transmittance would become direct factors of choosing crops and crop varieties. Most multi-span plastic greenhouses are at 50% to 60 %, and the greenhouses which covered by sunlight panel light transmission rate is 75 % to 80%, own main glass greenhouse products can reach more than 85%.

Insulation - A Stable and Sustaining Producing Environment

Heating energy consumption is a major obstacle to greenhouse operation in winter. Improving the insulation performance and reducing energy consumption are the most direct means to improve production efficiency. Insulation resistance ratio is ratio of roof covering material area and thermal envelope area to the area of land, which is a fundamental measure of thermal insulation properties. Insulation ratio higher, insulation properties go better. In general, multi-span plastic greenhouses are at 0.7-0.8, the glass greenhouse light transmission rate of 0.8-0.9, Our mutil-span greenhouse can reach more than 0.9-1.1 or higher.

Productive - Plant l Seasons, Harvest All Seasons

Our greenhouse excellent translucent insulation performance keeps a stable and sustaining environment to supply plants demand and increase crop yields, which is two to three times more than the open field or even higher on some other circumstances. Your greenhouse can be a world of personal creation and imagination, our designers and engineers have complete confidence to accomplish your dream. With proper regulate, control, scientific management, good harvest will be achieved.

Durability - One Time Investment for Life Time Benefit

Durability is mainly effected by material durability anti-aging properties and bearing capacity of the main structure. We dedicated ourselves to build strong and constant products,greenhouse is designed within the principle of life-span last more than 15 years under condition of maximum wind and snow load as 50-year return period based on your local climate situation.As operating in high temperature; high humidity environment with long-term, surface corrosion has become an important factor in the impact of greenhouse service life.Greenhouse main load capacity frame are made of cold-formed cold-rolled structure steel with additional process of hot-dip galvanized surface finishing, thickness of coating reach 150um - 200um can guarantee 25 - 30 years of use life.

Structure Steel Pipe of Greenhouse

Galvanized structure pipe has good strength, toughness , ductility and welding process performance as well as good ductility, the alloy layer is firmly attached to the steel substrate, so hot galvanized pipe can be cold- rolled , brushed , bending and produced with other forming process without damaging the coating.
GR profiles use highly automated production technology imported from Europe, process of welding, stamping, punching, roll forming, fixed-length cut off are all completed online, and can achieve continuous one-time forming even there are more than one arch-sharp to process, the profile has a bright finishing with no scratches, high accuracy, consistency, no length limit , good corrosion resistance and other characteristics.
These two steel profiles are prefect material for solar greenhouse engineering.

FAQ

1. What are main materials of solar greenhouse?

Our solar greenhouse materials mainly include light steel structure after painted or galvanized process, roof panels, door, window, ventilation fans, screws and other accessories.
2. How is your steel structure solar greenhouse performance in High Latitude zone?

Steel Structure Solar Greenhouse is built to deal with problems of lacking heat and solar light when planting crops with good property of insulation and heat reserving. Many of our clients from location between north latitude 45 - north latitude 60 had well proved its excellent performance within vegetable cultivation in winter.
3. How long can your steel structure greenhouse stand for service?

Our Steel structure solar greenhouse are designed for long-term service life purpose, as you can minimize your cost and maximize payback through long time usage. Normally, CMCO Steel Structure Solar Greenhouse has 20-30 years life time based on climate and environment situation and only need very easy step to maintain and renew.
4. Is Steel Structure Solar Greenhouse aseismatic?

Steel Structure Solar Greenhouse can stay solid and stable benefiting from its light weight and steel's elasticity, force of horizontal momenta from earthquake can be easily conducted and unload, our greenhouse are designed to deal with M8 earthquake and stay intact, and we can reinforce the steel frame to improve the aseismatic performance for any of your special demand on earthquake-resistance.
5. How long it takes to build Steel Structure Greenhouse

Steel Structure of Greenhouse is prefabricated within factory and can be easily installed by non-technical worked under an illustration. From our experience, a 2000 m2 greenhouse can be assembled and get ready to use within 30 days by 5 workers.
