Types of steel rebar
Rebars are profiles that have a cylindrical and solid surface, and the use of their ribbed surface is seen more in the building. The material of the rebars is steel, but nowadays there is a great variety in the production of this product among different companies, so In the market, we get to know the types of rebars according to their use. There are two types of steel rebars, ribbed and simple, and another category called coiled rebars, which are considered as rebars.
Simple bars
Usually, plain and non-treaded steel rebars are called thermal rebars and they are used industrially, but they are used for construction and civil engineering. 25% and they have higher flexibility, and this is due to the low percentage of carbon in this alloy, and there is no obstacle to bending and unbending operations on it, and they have industrial uses.
Ribbed rebar
There are a lot of ribbed steel rebars in the market, they are very brittle and brittle, that's why they avoid welding on them. Other types of rebars are known as semi-brittle, and due to their semi-brittleness, bending and opening operations Bending on them is done less often and they do not have the ability to change sharp shapes.

Carbon rebar
These rebars, which are also known as high-carbon rebar or black rebar in the market, are widely used. They can be used in any project, except for a few exceptional cases, but these rebars do not have much resistance and they get tired very quickly. If their erosion is high, they will break and then the concrete will break, that's why they use more resistant and suitable rebars called black rebars to place rebars in humid environment. Black rebars are more durable, stronger and more elastic.
European rebar
European rebars have manganese, they have many features, one of these features is their high bending ability, and they are a suitable option for earthquake-prone areas, and they are also used for structures that require integration.
p>Epoxy rebar
Epoxy rebar is the same as black rebar covered by epoxy materials, they have a higher relative resistance, although the epoxy is a thin layer on the black rebar, although they have a high resistance compared to other rebars, but the thin layer of epoxy is very delicate. and their resistance against pressures is reduced.
Galvanized rebar
Galvanized rebars are from another category of rebars, whose resistance is 40 times higher than epoxy type and more against corrosion, due to their resistance and reduced vulnerability in these products, they also have a higher price.
>Polymer bars (GFRP)
Usually, these FRP rebars are used instead of steel rebars because they have extremely high durability and strength against corrosion and significantly reduce damage against acidic substances and corrosive environments, that's why it can.
