Translucent - 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 our greenhouses are coverd by sunlight panel light transmission rate is 75 % to 80%, own main glass greenhouse produxts 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, CMCOSTEEL mutil-span greenhouse can reach more than 0.9-1.1 or higher.

Productive - Plant l Seasons, Harvest All Seasons

CMCOSTEEL greenhouse excellent translucent insulation performance keeps a stable and sustaining environment to suppy plants de,mand 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, CMCOSTEEL 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. CMCOSTEEL 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.

Modules = Support frame + Covering + Opening + Cooling system +Irrigation system

Support frame

Galvanized square tube 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 square tube 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.

Roof and wall covering material

There are many covering material options for a solar greenhouse project, however plastic film, glass and sunlight panel are the most chosen ones.

Film with cost very few, easy to install and maintenance, wide coverage together with other features makes it comes to the first choice for covering material, please note that it may cause white pollution after the film passed its service life.

Glass is often used to design a long-lived greenhouse due to good light transmission properties. Insulation properties are between film and solar panels. Glasshouse necessary accessories and sealing material prices are a little bit higher for glass project, also larger mass, so the skeleton load increases as well as steel usage, means higher overall costs.

Sun panels, is a high-tech, energy saving plastic sheet with excellent comprehensive performance.

• Light weight: Weight is one-fifteenth of the same thickness of glass
• High strength: Anti-impact property is 16 times more than glass
• Energy saving: Saving 40% more energy compared with greenhouse enveloped by glass
• Durable: Light transmittance only reduce 10% after more than 10 years usage
• Resistance: Resistant to cold and heat : between -40 centidegree ~ 120 centidegree, solar panels do not produce distortion

Opening windows and ventilation system

Top window and side window: Located at the roof and sides, can be one-way or two-way opening, rack and pinion drive, smooth operation, long life and good sealed insulation.

Cooling system

In order to maintain the greenhouse air temperature, ground temperature within a proper range of crop growth and development, the heat flows into the greenhouse must be excluded for cooling purpose. Hot and humid environment can be a serious impact for plants output.

Cooling system included internal circulation fan, wet curtain / fan cooling system, micro-mist cooling system.

Irrigation system

Modern solar greenhouse requires advanced water-saving irrigation facilities to meet the growing demand from crops. The irrigation water is extracted from the source with the proper pressure after purification, filtration and other treatment, then piped into the field.

CMCO Steel provide all kinds of irrigation system plans from pipe irrigation system, drip irrigation systems, micro irrigation system and walking sprinkler system based on your demand and situation.

agricultural greenhouse can not only be used for farming, but also can be used for poultry industry with good performance of constant temperature and constant humidity. We had designed and constructed many projects like Hydroponic farm, Three-Dimensional Breeding Center, Tropical Plants Garden, Flowers & Plants Market, Floral Hall and Ecological Restaurant.
