Fit every frame, match every structure

• Efficient design, eliminates the need for structural trusses.
• Common configurations in subtropical climates.
• Gables consist of two arches that meet at the ridge.
• Optional Configurations for commercial greenhouse: With/without roof windows.
• Common span between gutters: 9.6 meters to 11.2 meters (30 feet to 40 feet).

Compatibility with polycarbonate sheets

• One polycarbonate sheet spans from ridge to gutter, with purlins spanned according to required load bearing.
• Window and ridge cap elements are available for commercial greenhouse.

• Composed of two inclines or arches of different heights and lengths with a fixed open vent between.
• Common span between gutters: 6 meters to 12 meters (20 feet to 40 feet).
• Common in desert regions and tropical climates, where open ventilation is required.
• Typically designed for PE film but can easily be retrofitted using corrugated or multiwall polycarbonate sheets.

Compatibility with polycarbonate sheets

• One for each slope, polycarbonate sheet, ridge to gutter.

• A very simple design of two slopes of equal pitch and width.
• A very strong and firm structure. Suitable for large greenhouse that are planned for heavy wind / snow loads.
• Common span between gutters in large greenhouse: 9.6 meters to 11.2 meters (30 feet to 40 feet).
• Most common configuration for cold and temperate climates.

Compatibility with polycarbonate sheets

• A common glasshouse structure which can easily be retrofitted with corrugated polycarbonate sheets without any structural modifications.
• One polycarbonate sheet spans from ridge to gutter, with purlins spanned according to required load bearing.
• Windows and ridge cap elements are available.

• A basic design of a bent arch built with steel pipe or square steel tubing
• Usually spans are 6-10 meters (20-33 feet), but wider arches are common.
• Allows excellent solar energy penetration

Both corrugated and multiwall polycarbonate sheets with attention to few important details:

• The sheets are bent within the allowed bending radius. To access our bending radium calculator click here
• A uniform arch all around
• Ridge purlin required
• One sheet gutter-to-gutter installation is possible, as long as guidelines are maintained to prevent residual stress.

• Two moderate, long inclines that create a wide open structure without internal support columns.
  Advantage: Large greenhouse area, column free, open area. Suitable for garden centers , sprouting plants, storage areas, work areas with conveyors or large volume equipment

Compatibility with polycarbonate sheets

• Each incline is made up of a either one sheet ridge-to-gutter, or number of overlapping sheets, depending on required length.
