The use of steel bars
Most people associate steel bars with the reinforcement of foundations and, in general, with construction. Indeed, it is in this area that these products are most often used, although it is worth knowing that there are other applications for steel bars. There are three popular types of applications.
The building material of almost every structure is concrete. Concrete alone is not enough to provide a building with stability, strength, and durability, as it is a relatively fragile material. Reinforcing bars are therefore used to strengthen the concrete. Round bars are almost always used for this type of reinforcement.
As well as other uses, round bars are used in beams, columns, and foundation benching. Together with trusses, they form a solid basis for any structure. Their role is to increase the building’s resistance to loads – both vertical and horizontal. Round bars are also perfect for the construction of power poles, bridges, and hall roofs in large industrial facilities.
Also, one of the most common uses of steel bars is the construction of steel structures such as fences, gates, balustrades, and trusses. Square bars are usually used for this purpose, although round bars can also be used.
Types and properties of steel bars
Steel bars can be classified in many ways. Different types of rods are connected with different properties, which determine the intended use of the products. Here we discuss the basic classifications of steel bars.
The most popular category of steel bars is the cross-section category. There are round, rectangular, square, and hexagonal bars. Rectangular bars are commonly referred to as flat bars and are very often used in gates, fences, and industrial machines. However, the greatest demand is for round bars, as they are best suited for concrete reinforcement.
Steel bars can also be categorized according to the type of their surface. Smooth bars and ribbed bars both belong to this classification. It is clear that ribbed bars are much better when compared with smooth bars when it comes to adhesion to concrete.
A separate issue is the categorization of bars according to their durability There are five distinct markings: A-0, A-I, A-II, A-III, and A-IIIN. The markings written this way are ranked from the lowest strength to the highest strength.
More about the markings. It is worth knowing that the markings provide additional information about the properties of the bars. For example, the letter “S” indicates that welding a rod is possible, and the letter “G” indicates that there is manganese in its composition, and the number indicates the amount of carbon.
Let’s not forget that steel bars can also be categorized according to the type of steel used for their production. The market offers bars made of boiler steel, heat-resistant steel, carbon steel, free cutting steel, non-alloy steel, tool steel for hot work, and steel for carburizing or refining. We can also come across reinforcing bars coated with additional coatings, for example a zinc coating, which ensures corrosion resistance.
