There are four common frame styles for multi-span greenhouses. Next, greenhouse accessories manufacturers will introduce them in detail.

1. The double-membrane greenhouse on the left, the single-membrane greenhouse on the right, and the patterned frame are commonly used to cover the glass or sunlight board.

2. A single-layer arched frame, covered by a single-layer film. The frame data is composed of columns, longitudinal beams, gutters, external shading skeletons, and surrounding protective beams. This type of skeleton material is cheap, light in weight, and convenient to install. It is the main skeleton type of greenhouses nowadays.

3. The detailed drawing of the connection between the sink bracket and the herringbone joints, etc. The greenhouse frame is connected with hot-dip galvanized bolts, which has strong anti-corrosion and rust-proof properties and strong structural stability.

4. Double-arch frame. The frame of this kind of greenhouse is improved on the form of a single-layer arch, and a layer of inner arch is added. A trip of c-shaped steel was added under the gutter. Because of the addition of a layer of inner arch, the thermal insulation function of the greenhouse has been improved. However, the natural ventilation function of the greenhouse is affected, so this kind of greenhouse is generally used for flower cultivation.
