Metal structures are metal products that are used in the construction of structures and buildings of different sizes and purpose. They are made from a welded or steel profile. Aluminum, cast iron, various alloys and ordinary types of low alloy steel are used as materials for the manufacture of metal structures. Durability, reliability, high strength and at the same time lightness are the main advantages of metal structures.
A wide variety of metal details ensured the intensive growth of industry in our country. Today, the manufacture of metal structures has reached a completely new level, because new production technologies and building materials are constantly emerging. One of the most affordable and strong materials is the steel that is used in the construction of buildings for the military and industrial fields, as well as in civilian construction. Aluminum is very popular, which has light weight. It is used in the production of enclosing and supporting metal structures.
Metal structures are in demand due to excellent characteristics, namely:
– good transportability indicators;
– metal structures installation speed;
– distinguishing welding, electrical conductivity and thermal conductivity of metal;
– high strength;
– High durability and reliability.
But metal structures have disadvantages, for example, it is small resistance to corrosion under the influence of various gases or a humid medium. Therefore, metal structures need additional processing in order to increase their protection against corrosion. For this, paintwork materials are used, and the method of hot zinc.
In the field of use of metal structures, the most pressing issues are those that relate to a decrease in the complexity of the production process and the work of installation work, saving metal, etc. To protect the metal from corrosion, it must be stored in a dry place well protected from moisture. A good medium for storing metal structures is a medium with air humidity below 60%. It is unacceptable to storage products near salts and gases, which are sources of the release of aggressive media. To protect metal structures, different products are used, which provide their reliable protection against corrosion during operation.
