Whether it is the simplest single arch shed, a large-span arch shed, a daylight shed, a multi-span film shed, or a multi-span glass shed, the most important investment in the construction process is the steel frame of the greenhouse, which is also the most important load-bearing part.
The steel frame mainly plays a load-bearing role, bearing its own weight and resisting wind and snow. The quality of the steel frame directly affects the service life of the greenhouse, so the steel frame of the greenhouse must use hot-dip galvanized material, and galvanized strip pipes cannot be used for cheapness.
The following are the main reasons why hot-dip galvanized materials are widely used:
1. Corrosion resistance: Hot-dip galvanizing is a process in which steel is immersed in molten zinc to form a zinc coating on the surface of the steel. This zinc coating can form a strong protective barrier on the surface of the steel, effectively preventing corrosion factors such as water and oxygen from reacting with the steel.
2. Durability: The durability of materials treated with hot-dip galvanizing can be greatly extended, especially in variable outdoor weather conditions. Compared with cold-dip galvanized (electrogalvanized) steel materials, hot-dip galvanized zinc layers are thicker and have a stronger bond with steel, so hot-dip galvanized steel can last longer without rusting under the same conditions.
3. Comprehensive protection: The hot-dip galvanizing process ensures that every corner of the material is covered with zinc, including sharp corners, sharp edges and hidden holes, which are the most easily overlooked and where corrosion begins first.
4. Self-healing: The zinc layer has a certain self-healing ability. Even if the coating is damaged, the zinc can form an anti-corrosion oxide around the damage, thereby continuing to protect the steel from corrosion.
5. Economical: Although the initial cost of hot-dip galvanizing may be higher than some other coatings, the overall lifecycle cost (including repair, replacement and maintenance costs) is generally relatively low due to its long-term durability.
6. Easy maintenance: Compared with steel that needs to be painted regularly, hot-dip galvanized steel requires almost no maintenance, which can save long-term maintenance costs and labor.
7. Environmental adaptability: Greenhouses are exposed to the outdoor environment all year round and are affected by natural conditions such as humidity, high temperature, and ultraviolet radiation. Hot-dip galvanized materials can adapt to these conditions and maintain structural integrity and functionality.
8. Environmental protection: The hot-dip galvanizing process is more environmentally friendly than other protection methods such as painting. Organic solvents may be used in the painting process, which may cause environmental pollution after evaporation.
Therefore, hot-dip galvanized materials are a very ideal choice in the construction of greenhouses. Their good durability and corrosion resistance can ensure the stability and durability of the skeleton structure, extend the service life of the greenhouse, reduce maintenance costs, and improve the use effect of the greenhouse.
Single arch sheds generally use hot-dip galvanized round tubes, large-span arch sheds and daylight greenhouses generally use hot-dip galvanized oval tubes, multi-span film greenhouses and glass greenhouses generally use hot-dip galvanized square tubes and round tubes. No matter what specifications of square tubes and round tubes are used, they must use national standard hot-dip galvanized materials. Only in this way can the greenhouses built be used for a long time, and they are safer and more durable.
