What is a bolt of bolt?
Today, the use of bolted structures in the industry has increased significantly so that in the past these structures only included industrial sheds and petrochemical complexes and structures used in the oil and gas industries. Currently, the use of these structures in residential, office and commercial buildings, which are also built in cities, has grown significantly.
One of the most important reasons for using bolted joints (metal bolted structure) in industrialized countries is the lack of welding, the installation time of the structure in difficult situations, and the faster execution at the installation site compared to welded structures. Also, the skeletons that are produced in the area of construction projects due to the limitation in supplying sufficient electricity and the use of modern welding devices (with a high and standard penetration rate), the absence of heavy industrial tools, experienced teams, correct painting and rust removal, etc. Not only are they lacking in quality, but they are quite cumbersome and have a time-consuming process that will undoubtedly lead to creating traffic on the roads and disturbing the neighbors.

Comparison of welding structures with bolt structures
Skeletons that are produced in the area of construction projects due to limitations in supplying sufficient electricity and using modern welding devices (with high and standard penetration rates), lack of heavy industrial tools, experienced teams, painting and rust removal. Sahih and... are not only lacking in quality, but they are quite cumbersome and have a time-consuming process that will undoubtedly lead to traffic in the crossing and disturb the neighbors. The traditional method of making a skeleton on site in terms of connection and erection also has a high cost due to the crane in addition to the mentioned items. Considering the earthquake-prone nature of our country and the unfortunate events that took place in the past years, especially in Bam and Kermanshah, a new approach and attitude to the industrial production and standard of building skeletons has emerged, because these types of buildings are specially designed and executed in an industrial and modern way. They have good resistance compared to traditional skeletons. Another economic point is the lower cost of production and installation compared to the usual traditional method in general, which becomes significant when there is a shortage of supply and an increase in the price of steel beams. Due to the range of design in sheet beams and prefabricated structures, calculations, space creation and loading are done with high freedom of action.
Prevent Corrosion of Connects
The durability of connections depends on the degree of corrosion of the environment during service. Corrosion damage causes premature failure, so corrosion protection must be considered in order to maintain the integrity and integrity of the structure throughout its life. Bolts and nuts in steel structures are one of the important components on which the integrity of the whole structure depends. To protect against corrosion, resistant metals or protective coatings can be used before and after installation. Using connections made of resistant alloys is the best solution in highly corrosive environments. Protective coatings include zinc, cadmium, and precious metals such as nickel and tin, which must be applied prior to installation. In the case of more active metals such as zinc and cadmium, the thickness of the coating is very important, but thin coatings of nickel and tin can protect the structure well in the long term.
