Outstanding Features of  Poly Tunnel Greenhouse :

a)  Square tube ground stakes & bows for added strength.

  An engineering analysis comparing 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 37% stronger than the 1.90” round pipe.

 b) High Tunnel performance     

The greenhouse has some of the tallest side wall and peak heights on the market today.

4' side wall of 16' highest peak height

6' side wall of 18' highest peak height

c) Gothic Arch Profile

We design each of our structure with a steep gothic arch profile as required for increased strength and to  aid in snow/ice removal.

d)  Purlin Designs

our 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 bow.

e)  WIND BRACING

Most  structures are provided with wind bracing kits. Wind bracing is key to maintaining structural integrity

especially in high wind regions.

f)   Easy Installation

With complete and comprehensive installation instructions, the  Cold Frame is one of the easiest structures to erect.

In addition,Rough Brothers China 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.
