What is the design life of the glass greenhouse?
How much difference does each system material
The glass greenhouse is a spire-style greenhouse covered with glass all around. It is currently the type of greenhouse with the highest investment and construction cost among the greenhouses. So how many years can a greenhouse with an investment of 200,000 to 300,000 yuan per mu of land be used?
1. The concept of glass greenhouse and main system materials
In the industry, greenhouses with a textured (tri-spire) style are collectively referred to as glass greenhouses. The surrounding material of the glass greenhouse is glass, and the top covering material is glass or sunlight board. Glass greenhouses are generally equipped with external shading system, internal shading system, internal thermal insulation system, fan water curtain cooling system, top electric window opening system, power distribution system, etc.
2. Design life and service life
1. Steel frame material
The standard skeleton materials are all hot-dip galvanized materials, and the steel is a factory-customized product. Hot-dip galvanized bolts are used for assembly on site, with a design life of 15 to 20 years.
2. Cover glass
Glass is an amorphous inorganic non-metallic material with stable chemical properties and a service life of more than 15 years.
3. Sun panel
On the top of glass greenhouses in the north, we like to use sunlight panels as covering materials, and the design life of national standard panels is ten years.
4. Shade net
Greenhouse shading nets are divided into two types: external nets and internal nets. The outer shading net generally uses a round wire black net, and the inner shading net generally uses an aluminum foil inner net. The national standard design life of the two nets is five years, and the actual service life is six or seven years.
5. Geared motor
The geared motor has a service life of more than ten years under normal use.
