1. overall dimensions of plastic greenhouse

Such greenhouse in different countries have different dimensions. But overall, the General span greenhouse in 6~12m, in 4m Bay, eave height 3~4m. To natural ventilation mainly of even building greenhouse, in side window and roof window joint using Shi, greenhouse maximum width should be limit in 50m within, best in 30m around; and to mechanical ventilation mainly of joint building greenhouse, greenhouse maximum width can expanded to 60M, but best limit in 50m around; on greenhouse of length, (from operation convenient of angle,) best limit in 100m within, but no strictly of requirements.

2. main structure

Main structure of plastic greenhouses are generally using hot-dip galvanized steel for the main bearing structures, factory production, installation on site. Due to the light weight plastic greenhouse, weak resistance to wind and snow loads, so to have fully taken into account the stability of the structure as a whole, usually in the room the second cross or Bay to set vertical bracing, greenhouse envelopes, and should also consider setting the necessary space on the roof supports. Best brace (lift rod) is anchored in the Foundation to form a spatial system.

Main structure of plastic greenhouses at least 8 wind resistance ability, General requirements for wind resistance up to 10 levels.

The main structure of the snow load bearing capacity according to the construction area snow conditions and greenhouse in winter set. In the North, design snow load of not less than 0.35kN/square meters.

For the annual run of plastic greenhouse, should also consider issues such as weight equipment, plant loading, loads, such as maintenance factors.
