20ft wide Straight Wall Profile



20 ft wide Straight Wall Profile

Named after Redding, California’s iconic Sundial Bridge, our 20×100 straight wall greenhouse is equipped with 1.58OD 14-gauge metal hoops (including a dep collar). Spacing is set at 5ft on center with three runs of 1.38OD 16-gauge purlins. All purlins are attached with premium aluminum cross connectors. End wall kit consists of 1.58OD 14-gauge metal with appropriate hardware for framing in end wall.

We use 8ML String reinforced 3-ply clear poly on all our kits. This poly has a light transmission of 85% and a 4-year rating. Black and White Poly for Light Deprivation is also 8ML String Reinforced to hold up against Mother Nature’s unexpected weather.

2” Roll Bar is used for Roll-to-Peak light deprivation. An HD insert is used throughout the full length of the tube to add weight for a tighter, more secure roll up/down.
