2" Square Bow Assembly
2-1/4" Square Ground Stake
SQUARE TUBE DESIGN
The WINDJAMMER SERIES 5000
structure incorporates square tubing into its ground stake and bow
assemblies for added strength.
In our 30’ wide and 35’ wide greenhouses, we incorporate 2-1/4” square
ground stakes (12 gauge) and 2” square bow assemblies (16 gauge).
An engineering analysis comparing Golden Pacific Structures’ 2” square
tube bow to a typical 1.90” round pipe reveals:
1.90” Round Pipe -14 Gauge
2” Square Tube – 16 gauge
A = 0.4738 in2
A = 0.5031 in2
I = 0.1959 in4
I = 0.2434 in4
S = 0.2062 in3
S = 0.2630 in3
Based on the SECTION PROPERTIES alone, our
2” square tube is 27% stronger than the 1.90” round pipe.
Easy Guide Driving Tools
In so much as we recommend all ground
stakes be set in a concrete filled footing we do offer, for those growers
wishing to drive ground stakes into grade, a tool designed to keep the
holder a safe distance from the sledge hammer. This tool also allows the
holder to “square” the ground stake to the string line.
HIGH TUNNEL PERFORMANCE
WINDJAMMER SERIES 5000 structures are designed with ultra tall side wall
and peak height.
SIDE WALL OPTIONS
Cold Frames are provided with a
4’ or, optional, 6 ‘ tall side wall. With the Golden Pacific Structures
design, we don’t even begin the bend before the 4’ or 6’ mark creating
plenty of working and growing room.
The WINDJAMMER SERIES 5000 structure is
designed with extreme peak heights to maximize healthy growing
GOTHIC ARCH PROFILE
We design each of our
structures with a steep gothic arch profile as required for increased
strength and to aid in snow/ice removal.
Golden Pacific Structures’ purlins
are secured to each bow with a heavy-duty clamp assembly. All bows are
provided pre-marked to illustrate the location of the purlin on the
Most WINDJAMMER SERIES 5000 structures
are provided with wind bracing kits. Wind bracing is key to maintaining
structural integrity especially in high wind regions.
With complete and comprehensive
installation instructions, the WINDJAMMER SERIES 5000 Cold Frame is one of
the easiest structures to erect. In addition, Golden Pacific Structures
offers in house installation service support and can, if desired, line up
qualified Building Contractors capable of completely installing the
greenhouse structure along with all equipment necessary.
