Hot dip galvanized polytunnels represent a sound investment for anyone serious about fruit and vegetable production. Even if the initial cost is higher than , the long term benefits can not be matched by any other type of construction. Protection, durability, flexibility are among the pluses that we will develop below in this blog.
1. Protection against weather conditions
A standard greenhouse made of galvanized steel, will help anyone realize their dream of growing vegetables at home. Fresh tomatoes, tasty aubergines or succulent peppers can be yours if you are motivated. With a polytunnel in your garden, you can save a lot of money. Other types of structures made of aluminum and glass, wood or PVC are either much more expensive or less effective and long lasting. Our modular frames allow you to extend your production facility at any time. Compatible elements are kept in stock and can be ordered for all sorts of modifications.
A typical tunnel or greenhouse provides protection against most external factors, such as weather conditions (wind, rain, hail or snow). In addition, access to crops by pests is also limited and they can not damage them. Various technical solutions used in polytunnels accelerate the cultivation process and ensure a high quality harvest. Integrated systems intended to control irrigation and fertilization are widely available. In order to increase the efficiency of the growing process, you can create a favorable climate inside the installation. Tunnel and greenhouse facilities also provide the opportunity to treat and protect crops against pests and diseases. Harvests are possible whatever the weather conditions, which is not the case with an outdoor site.
Depending on natural conditions, such as weather, climate, type of crop. Different technical solutions are used to achieve the same goal: obtain the best possible harvest.
2. Equipment and systems to support culture under cover
In tropical regions, greenhouses are generally made of a simple structure. Rarely equipped with technical monitoring and control devices. These installations are mainly covered with a thin foil that serves as protection against the wind and other destructive natural parameters.
In areas with a more diverse climate. Such as in Europe, the United States or Russia, with very cold winters and hot summers. More complex constructions and systems are needed. As a result, the devices used in these locations are more expensive to implement, operate, and maintain. For example, it may be necessary to use heating in winter and cooling systems during summer.
The key to success in this industry is to find the most suitable and effective solution to meet the specific climatic conditions in each region of the world. Sometimes, the initial investment may seem prohibitive. But thanks to the good development of the farm and the benefits acquired, the initial contribution is quickly compensated and generates profits.
3. Hot dip galvanized polytunnel
Galvanizing is a proven and widespread method of refining and protecting steel to prevent corrosion. Research has shown that a galvanized part has a corrosion resistance twelve times higher than pure steel.
During a hot-dip galvanizing process. Properly prepared steel elements are immersed in liquid zinc, at a temperature of 450 degrees Celsius. During this bath, zinc reacts with steel, generating a zinc coating with a thickness depending on immersion time and temperature. The zinc deposit occurs outside and inside the element, providing total protection. Such treatment protects steel elements against weathering, abrasion, mechanical damage, and corrosion in particular.
4. Hot dip galvanizing or electrogalvanizing?
The cost of hot-dip galvanizing is slightly higher than of electrogalvanizing. This higher price is also synonymous with superior quality. What is the difference between hot-dip galvanizing and electrogalvanizing? This latter method provides a thinner and less durable zinc coating. In addition, this treatment can cause problems in places difficult to reach.
Hot-dip galvanizing seems at first more expensive, but in a long-term perspective, unlike electrogalvanizing, it virtually eliminates the cost of renovating the element. A paint coating will provide additional protection. By choosing a hot dip galvanized structure, you have the guarantee that it can be used for many years without the need to restore its appearance and properties later.
Krosagro, manufacturer of steel structures, can supply all types of steel grade, from black steel to galvanised and hot dip galvanised. Bending of elements and production of accessories (anchors, steel clamps…) are all performed by the company, thanks to modern production tools and qualified staff.
Overall, hot dip galvanized polytunnels are an excellent solution for the agricultural industry, as well as private users. They deliver optimal production of fresh fruits, vegetables, flowers and plants throughout the year. The amount of crops generated by tunnels is much higher now than those coming from traditional open field production. The superior quality of yield is another advantage of these constructions. Such a result can be achieved in a relatively short time with the right installation, protected by hot dip galvanizing.
