Which greenhouse type is typically curved and resembles a half cylinder?

• A. Sawtooth
• B. Quonset
• C. Lean To
• D. Gutter-connected (Ridge-and-furrow)

Answer: (B)

Quonset greenhouses use a curved arch frame that forms a half-cylinder roof. This arch shape creates a smooth, continuous shell, distributing loads efficiently and maximizing interior space without internal columns. It’s also typically economical and quick to build, with galvanized steel arches and a plastic or film covering. The other designs have straight-sided profiles: a sawtooth layout features jagged roof sections for ventilation, a lean-to attaches to an existing building with a single sloped roof, and gutter-connected ridge-and-furrow is a long row of bays with shared gutters and straight ridges, not curved.
