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.
