Ideal for vegetables, fruit, flowers and more. Our round high-tunnel protects your crop, and enhances your yield and profitability. Our greenhouses come as complete kits that include all tubing, hardware, fasteners, 6-mil, 4-year poly and a complete set of color-coded directions with photos

TUBING

  • Frames are manufactured from triple-galvanized steel tubing
  • Steel framing includes 1-3/8” galvanized steel hoops. Each hoop is composed of three ribs that interlock and are Tek-screwed together.

HARDWARE

  • Ground posts are 1-5/8” galvanized steel tubing and 45” long, to be driven 21” deep, 24” above grade
  • Commercial-grade cross connectors for all 5 purlin runs. Very quick and easy to install.
  • Galvanized 1-3/8” X 2” X4” end-wall connectors
  • C-Channel and spring lock wire to connect poly sheeting to tubular purlin
  • Two PTO sidewall roll-up cranks and 6” long PVC poly connectors to connect poly to sidewall roll-up tube. We suggest minimum of 5' roll-up height for ventilation.

FASTENERS

  • Fastener package includes all nuts, bolts and Fastenal Tek screws. We even include a Tek screw driving bit and two 5/16” jobber drill bits.

POLY

  • GT4 greenhouse film (clear or white) is produced using advanced technology, resulting in a greenhouse film that is tough, clear and long- lasting. 

Manufactured with state-of-the-art extrusion equipment and new high tech polymers, GT4 products offers superior strength and toughness, higher light transmission and guaranteed longer life.
