Product Description:
Agra Tech has developed a horizontal trussed shade structure to provide a retractable shade system. Built to Agra Tech's high standards of strength and quality. Top & Bottom chords are formed of galvanized steel tube. Webs are 1 3/8" diameter steel tubing.
-
Multiple widths up to 42' clear span with 12' bay spacing. 30' width is standard.
-
Trusses are 18" - 24" deep set onto 4" diameter or 4" square side columns and 2 7/8" diameter interior columns.
-
Curtain operation is by the same reliable push-pull rack & pinion system as our indoor curtains.
-
Stainless steel wires 18" below and 36" above safely contain fabric.
-
Hooks on the leading edge prevent fabric from escaping over the leading edge.
-
Racks are steel. Pinion assemblies are Dutch made.
-
Steel channels on the truss accept the leading edge.
There are several advantages of a retractable shade house over a fixed shade house:
-
Retractable shade houses can be opened after a rain to reduce humidity, humidity which encourages insects, fungus, and molds.
-
Fixed black shade causes plants to grow more slowly and leggy. With a retractable shade system, the roof can be opened to expose plants to the optimum amount of sunlight.
-
Just hit a button to open your roof to harden off your crop rather than having to move the plants, thus saving huge amounts of labor.
An added Bonus:
Agra Tech's Retractable Shade or Trussed Shade Structure can be transformed into a truss or arch house at any time.
