Turnkey Project - Establishing
When our engineers design a greenhouse structure they have to consider multifactor as of durability to ease of use. In order to meet the high standards of the industry our main principals of planning are as follow:

a. Durability of the structure, a factor that have a direct affect on your profitability, All of our greenhouse models are made of hot galvanized steel pipes and profiles ( model dependent). Our models are engineered to withstand a wind velocity of 150 km/hr and load of 25kg/sqm the manufacturer guaranty for said structure is 10 years.
b. Ease and friendly instillation, our instillation system is based on fitting parts with out wilding post galvanization.
c. Cost effective material utilization, greenhouse covers is fixed using aluminum profiles and warm treated wood.
d. Efficient air circulation (model dependent) utilizing roof and side vents.
e. Efficient utilization of cropping area lay out of accessories in advised manner to insure maximum usage of cropping area.
f. Adaptation to variety of crops and cropping techniques.
g. Proper drainage of rain and drainage in hydroponics and soil less media.
h. Minimal shading by supporting parts to insure efficient light transition.
i. Insect proof structure via utilization of inner insect screens.
j. Friendly lay out of accessories.
k. Labor friendly ease of use of system components.
l. Low purchase, maintenance and operational costs.

Roof and side covering:
Roof and side covering can have a major effect on the photosynthesis thus on your profitability three types o covers are normally used for greenhouses structure.

Traditional glass cover.
Traditionally greenhouses that were erected during the last century were covered with glass, mainly because it was available and permitted light penetration. Still glass is the cover of choice in cold areas. The cost of the structure and the problems associated with maintenance of the glass cover led to new development and today most of the greenhouses erected at none European countries (arctic models) are polyethylene or polycarbonate covered.

Polyethylene Soft Cover.
Problems identified during the last two decades and significant development of the polymer chemistry led to the development of new generation of polyethylene covers that are will adapted to the needs of the industry.

The possibility of including additives to the polymers presented the possibility of modifications that solved diversity of problems associated with generation of microclimate with in the greenhouse:
a. Excellent light transmition in the spectrum required for photosynthesis.
b. Transmition of diffused light enhancing photosynthesis at the lower parts of the plant.
c. Inclusion of Anti fog materials that prevent water dripping due to condensation.
d. Inclusion of anti UV elements that enhances the durability of the polyethylene.
e. Utilization of addatives that select the wave length required by the crops.
f. Some polyethylene covers are engineered to prevent disease outbreak and insect penetration.

Polycarbonate Rigid covers.
Polycarbonate is rigid cover that has the advantages of flexibility and durability while maintaining its light transmition capabilities. The advantage of the polycarbonate as compared to the glass is its lighter weight and its flexibility. This type of cover is double layer and is will isolated as compared to glass. The ease in handling, its UV, heat and cold resistance combined with its durability make it a cover of choice at snowy regions.
