Introduction of types of rebar and its use in construction:

Rebar is a steel rod that is produced in different dimensions. Its application in building construction is to increase the strength of concreting and building endurance. We have two general divisions in rebars: 1. Ajdar 2. Simple Due to the diversity of these rebars, we divide them into three types of rebars: A1, A2, and A3. We will discuss them further. A1 rebar: This rebar is made of soft steel and is often smooth and without treads, and is distinguished from other rebars due to its smoothness. Its other name is ductile rebar. Rebar A2: This rebar has a ribbed and spiral appearance, which can be seen from the beginning to the end in this way and is not interrupted anywhere. This rebar is also easily recognizable due to its appearance. A3 rebar: This rebar is in the semi-hard category and can be seen with a spiral ribbed shape. This rebar is not capable of welding and they are used in the main rebars of the structure and the longitudinal rebars of beams and columns.
