from $19,999Configured to your operation — build yours in the 3D designer for an exact price, then add it to your cart.

The Sun & Steel 100′ Multi-Span Greenhouse comes in two models to suit any expanding commercial operation. Designed for maximum interior volume and effortless scalability, both feature a towering 23-foot peak, a 12-foot interior clearance under the Warren truss, and a completely clear 30-foot aisle within each 9 m span (gutter posts only between spans). Covered in UV-stabilized poly film — 6-mil on the Standard, 8-mil on the Heavy — over a heavy-duty galvanized steel frame, these gutter-connect-ready structures allow you to seamlessly expand up to 30 spans without structural modification.

The Standard Model delivers proven commercial performance with 21 gothic arches spaced at 5 ft on centre—reliable, cost-effective, and engineered to shed snow naturally while maximizing your usable floor-to-eave space. The Heavy Model pushes structural integrity even further with 26 arches spaced at 4 ft on centre, upgraded 2.5 mm arch walls, larger Fink Truss W-bracing, and heavier pipe diameters throughout—built specifically for the toughest climates, heaviest snow loads, and highest-demand agricultural operations.

Key features

  • 21 gothic arches — spaced 5 ft apart — gothic arch profile sheds snow naturally
  • 23-foot peak height with 12-foot interior clearance under the Warren truss for maximum interior volume and headroom
  • 30-foot clear-span aisle within each span — no interior columns between the gutter lines, full floor-to-eave usable space
  • Fink Truss W-brace diagonals — additional resistance to racking and deflection
  • X-bracing on both end bays — lateral wind load resistance at the gable walls
  • 6-mil UV-stabilized poly film — roof cover, end wall panels, and side wall panels all included
  • Aluminum poly channel system with wiggle wire for fast, tool-free film installation and replacement
  • Gutter-connect ready — designed to expand to 2–30 spans without structural modification
  • Galvanized steel frame throughout — ground-driven anchor system, no concrete required
