A single-frame greenhouse usually consists of a single structure with a steel frame as the supporting structure. The covering material is generally plastic film, and sometimes materials such as thermal blankets are used to improve the thermal insulation performance.
Single-frame greenhouses are usually constructed using metal or wood as the main support material. Compared with multi-layer or composite structures, the single-structure frame greenhouse structure is simpler, the cost is relatively low, and the installation is more convenient.
