What are the best materials for the greenhouse frame?

galvanized steel, aluminum, wood and plastic pipes are all adequate materials for the construction of a structurally bitter greenhouse. Each type of material excels in one or more areas of the greenhouse construction. The use of the correct type of material for frame construction is essential for the strength and efficiency of the finished product. The position, size and design of the greenhouse frame determine the best type of material that is used during the greenhouse construction. The use of the wrong material type to create a greenhouse will increase the chances of damage to the frame in the colder months or collapse under the weight of snow or by heavy wind pressure. The plastic pipe does not have the ability to hold another weight of the greenhouse with heavy snow and becomes Brittle when it is subjected to long seizures of cold weather. Galvanized metal and aluminum are good heat conductors and increase the difficulty of heating the greenhouse; The metal frame is not internally insulated by foam insulation or from glass fibers. Wood framing materials do not require further insulation to contain heat and budou support other weights applied to the structure of collected snow.

Larger greenhouses require additional support to ensure that the structure does not disappoint. The plastic pipe does not have the power to bridge long open areas without further support. This eliminates the installation of other supportive support and increases the usable area of ​​the greenhouse. Both types of metal and wood have the ability to bridge long distances if the frame components are dimensioned to support the size of the structure. Another factor affects the best type of material for the greenhouse frame.

The frame style of the greenhouse is another factor that determines the best type of material that is used for a structural frame. When using any type of metal to create rounded greenhouse frames, specially designed and pre -made trusses are needed. Wood also requires special production techniques to create large radius curves for greenhouseframe. The plastic pipe has the ability to bend into large radius radius if the tube is correct to ensure a strong greenhouse frame. All materials are best when they match the size, shape and location of the finished greenhouse frame.
