Design: The
AF, or "aluminum A-frame," greenhouse consists of a hot dipped
galvanized steel superstructure with aluminum gutters and straight roof
bars bolted together with an aluminum ridge to form a peak with an angle
of 35 degrees. Covered with double polyethylene film, this angle allows
condensation to be directed to the drip gutter rather than fall to the
floor. This greenhouse is suited for retail as well as traditional grower
facilities.
Roof Structure:
-
Peaked double poly house
-
35 degree roof slope
-
Increased roof area and light
transmission
-
Peaked roof design controls condensation
drip.
-
Aluminum extruded hollow gutter
sections with poly locking system extruded directly into the gutter.
Spaced at 12 feet centers
-
Aluminum extruded half moon drip
gutter
-
Aluminum extruded gutter bracket
-
Aluminum extruded roof bars, 1-1/2
inch by 2 inch, spaced at 40 or 48 inch centers
-
Aluminum extruded bolted ridge
-
Roof able to accept roof vent,
optional
-
All stainless steel hardware
Glazing:
Double poly layflat tubes, 4 mil or 6 mil

All substructure materials are
manufactured using raw steel and then hot dipped galvanized for rust
protection.
-
Greenhouse structure is braced
with X-brace section and wind brace section using 1/2-inch round hot
dipped galvanized rods.
-
NGMA standard structural load
calculations are used unless otherwise requested by customer.
Custom Fabrication:
- Truss clearance, gutter and truss extension heights
custom manufactured per project.
- Girder trusses to eliminate posts.
- Slope of the greenhouse roof created by varying the
slope in the posts and the truss extensions above the truss. This
allows the truss and the land to be level.
- Framing of passage, overhead and sliding doors.
- Attachment to existing or new building.
- Non-standard bay widths manufactured if required.
- Greenhouses can be manufactured to accept:
- Shade/energy retention systems
- Irrigation booms
- Roof vent system
- Hanging basket systems
- Lighting systems
- Heating systems
- Crop support system
