Widely used iron in construction

Irons are used in different forms with different technical specifications in the construction of buildings. According to Isna, according to the announcement of Arad Ahan, in this article, we will introduce five steel and iron sections that play an essential role in the construction industry to complete a building in large volumes. Rebar and its types in the building Rebars are solid and cylindrical sections that are used in buildings and help increase the strength of concrete columns and protect concrete columns against shear and tensile forces. Rebars are produced in simple, ribbed types and with industrial grades A1-A2-A3-A4 and are used depending on the needs of the projects. Plain rebars with A1 grade are known in the market and have a smooth surface. These rebars are soft products with low strength, but on the other hand, they have high flexibility. Ribbed rebars have ridges on their surface that make them stick to concrete better. A2 grade spiral ribbed rebars are semi-hard and semi-soft products and have higher resistance than simple rebars. A3 grade ribbed rebar is another type of rebar, which is considered one of the hard steel products due to its greater strength and less formability than the previous two types. Compound ribbed rebar with A4 grade has ribs with a complex design on its surface, which has the highest resistance and the least flexibility in all types of rebar. This rebar should not be subjected to welding because it is a hard product. The price of rebar depends on the type, size, factory brand, etc. Five commonly used irons in construction Beams and the use of types of beams in buildings The main use of rebar is in the construction of the building skeleton as a column. The beams are sitting in the columns to take the load and pressure on the building from other materials of the building and pass it to the ground. The beams themselves will be classified into the following types: IPE beams: This type of beam, which is produced based on the standards developed in European countries, is the most used in the construction of projects in our country. The IPE beam has two wings and one web and looks like the English letter I. The most important feature of this type of beam is the same thickness along its wing. IPN beam: IPN beam can be considered the same as IPE beam with the difference that the thickness of the wing of this beam is not the same and it gradually decreases in the width of the wing. Another difference between these two beams is that the production of IPN beams is based on the standards of China and Russia. IPB girders: These girders are known as wide wings and the width of the wings is almost equal to the width of the girder. Wide wing beam is produced according to European standards. Honeycomb beam: this beam has empty hexagonal holes throughout its life, which will reduce its weight and price. These beams have high resistance against bending anchor forces and are longer than other types of beams. Iron beams have other uses such as making column bottoms, main beams, columns, intermediate beams, trusses, and narrow chromite beams.
