Shading nets are mainly used in summer, especially in the southern part of the country. Covering the sunshade net in summer mainly plays a role of blocking light, raining, moisturizing, and cooling; after covering the sunshade net in winter and spring, it also has a certain function of heat preservation and humidification. The sunshade net is made of polyethylene, high-density polyethylene, PE, recycled materials, new materials, polyethylene propylene, etc. as raw materials. After ultraviolet stabilizer and anti-oxidation treatment, it has strong tensile strength, aging resistance, Corrosion resistance, radiation resistance, lightweight, and other characteristics. It is mainly used for the protective cultivation of vegetables, Xianggu, flowers, edible fungi, seedlings, medicinal materials, ginseng, Ganoderma lucidum, and other crops and aquatic and poultry breeding industry, etc., and has obvious effects on increasing output.

   The quality of shading nets on the market is uneven. Some shading nets have a service life of only about one year, and some have low shading rates and are not suitable for use in multi-span greenhouses. The shading nets used in multi-span greenhouses are generally round wire outer shading nets. This kind of shading net has a high shading rate, usually 75%, but some can reach 90%. In the multi-span greenhouse outdoor shading net industry, most of the recycled materials are used. When the external shading net is applied to the multi-span greenhouse, it needs to meet the two requirements of long service life and high shading rate at the same time. However, due to the backward knitting technology of the external sunshade nets produced by many domestic manufacturers, the phenomenon of silk loss and lack of silk is more serious. Therefore, for multi-span greenhouses, it is recommended that you choose good-quality external shading nets. Below, the Shandong shade net manufacturer will show you how to choose a suitable multi-span greenhouse outdoor shade net:

   1. The net surface is flat and smooth, the flat wire is parallel to the gap, neat and uniform, and the warp and weft are clear and bright.

   2. Formal fixed-length packaging, clearly marked with shading rate, specifications, and dimensions.

   3. There is no peculiar smell, smell, and some are just a faint burnt smell of plastic.

  4. Good finish, with a sense of texture, deep black and bright, rather than a floating surface bright feeling.

  5. Moderate flexibility, elasticity, no hard feeling, no roughness, and a flat and thick texture.
