1, the single column, the span is generally between 8 meters 12 meters, the maximum use of land area. 2. No column structure, wide planting area, good daylighting effect and convenient for mechanized operation. 3, the use of all-steel pipe shed framework, strong and durable, long service life, generally in 20 years. 4. The steel pipe has good bearing capacity and strong wind and snow resistance. Galvanized pipe steel frame structure to better prevent steel pipe rust, corrosion. Extend service life. The advantages of carrying out all-steel pipe arch shed are: professional construction of various agricultural production shed, the company has 12 professional shed construction team, first-class construction technology, experienced, low prices. In many greenhouse arch shed, choose to build full-steel tube without column arch shed, can consider the following points: 1, the top of the arc, shed structure is simple, easy to build and disassemble, less one-time investment; 2. The steel pipe is used as the material of the shed surface, the frame is firm, the specification is unified, and the installation is convenient 4.
