Greenhouses may be constructed from several different
materials. Among the most popular are aluminum, steel, stone and
wood. Of these four, aluminum and steel is by far the most longest lasting. Aluminum may be extrude in various shapes
and thicknesses. This material can then be formed into
rafters, side posts and other structural components.
The efficiency and productivity of a greenhouse structure is
greatly influenced by its design. Also, the initial and long
term costs of the facility are effected by the type of
materials used. Ridge and furrow houses provide the greatest
efficiency in crop production. Aluminum is the most durable
and commonly used framing material for commercial greenhouse
structures.
There are 3 ways of constructing the Green House
Steel Structure : Structure prices vary greatly
depending on load, length, size of steel, round or square,
ground to ground are among our least expensive structures.
Please note the wider the house the less expensive per
square meter. Also it is wise to remember whether the
house is 40 ft long or 200' long you still have ends to
build, at least one door, etc. So generally the longer the
better - length should not be shorter than 48 ft. to 60
ft. |

Any lengths are available, from 48' (7.3m) to the
requirement of the customers. The basic design can be modified
with sidewalls up to 6' (1.83m), although 3' (91cm) is the
most common sidewall. Bays on 4' (122cm) or 6' (183cm)
centers, depending on strength required. Widths from 15'
(4.5m) to the requirement of the customers. Available with or
without ends. Clients often prefer to customize the ends to
fit their needs.
Many structures do not require ends. Gable ends are often
covered in Polycarbonate or hard, rigid material to encase
door equipment.
Types of coverings vary greatly. The most common is either
single or double inflated Poly, Polycarbonate, shade screen,
or black out films.
For strength and ease of construction, most clients prefer the
square steel, as attaching equipment and systems is easier to
do with a flat surface. We also have round and oval pipe. Pipe
sizes from 1 1/4" to 2 1/2" are available depending upon load
requirement. Square steel is more expensive than round, but
easier to work with.
Purlins are horizontal
supports that run from rafter to rafter. These structural
components are usually spaced 4-8 feet apart depending on the
size of the greenhouse. Purlins may sometimes be connected by
a cross tie. These provide additional support and may be
required in areas where high winds are frequent.
Side posts and columns are vertical supports usually ranging
in height from 1-10 feet. These structural components
deter-mine the height of the production area and greatly
influence efficiency. Sidewalls may also be vented to provide
cooling and insulation.
Wooden
Structure :
Wooden Structure : Wood is commonly used because it
deteriorates quickly in the moist environment of the
greenhouse. If wood is used, it is best to obtain
pressure treated lumber that "resists" decay. There are
several satisfactory types of this treated wood
available commercially like Nilgiries |
