Rebar reinforced concrete price

Reinforcing rebar reinforced concrete is one of the most important building elements that ensures the strength and durability of buildings. Iron works to enhance the concrete’s resistance to tensile and corrosion forces, and the quality of construction depends on choosing the appropriate reinforced concrete reinforcement. Therefore, we at Elkady Steel - the authorized distributor of Ezz and Al-Maraqbi Steel - offer you this comprehensive guide to choosing the best types, in accordance with approved engineering standards.

Reinforcing steel in construction

Reinforcing steel in reinforced concrete is the basic element in the construction of concrete structures, as it improves the performance of concrete and increases its bearing capacity. It is also used in many basic elements, such as columns, beams, slabs and concrete foundations.

The functions of reinforcing steel in construction include increasing concrete resistance to tensile forces, bearing excessive loads, achieving durability and sustainability of construction, in addition to cohesion with concrete and controlling cracks and thermal changes.

Types of rebar reinforced concrete

Different types of are available Steel rebar reinforced concrete, it is classified according to several criteria, such as texture, strength and durability, and the following are the most prominent types used:

A1 smooth rebar

A1 smooth rebar has a smooth surface without burrs, is used for work that does not require high bonding between steel and concrete, and is easy to form and weld, making it suitable for some specific uses, such as secondary reinforcement mesh.

A2 & A3 ribbed rebar

A2 & A3 ribbed rebar contains ridges that increase adhesion strength to concrete. A2 is used in projects with medium loads, while A3 has greater rigidity, so it is used in large projects that require high tensile strength. It is also suitable for structures subject to high loads such as bridges and high-rise buildings.

High stress steel reinforcement

It has a high tensile strength of up to 6000 kg/cm², and is used in prestressed concrete structures such as bridges and high towers.

Stainless steel reinforcement

Stainless steel reinforcement is characterized by its resistance to corrosion and moisture, which makes it ideal for use in coastal areas and buildings exposed to high humidity. This explains its higher cost than previous types, as it significantly increases the life of structures.

Galvanized iron

One type of rebar reinforced concrete is galvanized, coated steel With a layer of zinc; To protect it from rust, it is used in places that need additional protection against harsh weather factors.

Criteria for selecting appropriate reinforcement steel in concrete

Choosing reinforcing steel in reinforced concrete is one of the basic processes that affects the quality of construction, and requires adherence to several standards to ensure strength, durability and sustainability. The following are the most important standards that must be taken into consideration when choosing reinforcing steel:

1- Compliance with standard specifications

Reinforcing steel in reinforced concrete must comply with local and international standard specifications, such as the Egyptian Code (ECP), American Standards (ASTM), or British Standards (BS). These standards guarantee the quality of the steel and its ability to bear different loads.

2- Tensile strength and elongation

Reinforcing steel with high tensile strength must be selected; To prevent cracks in concrete under different loads, specifications specify the elongation rate of steel, to ensure its ability to absorb dynamic loads, such as earthquakes and strong winds.

3- Type of reinforcement steel

The appropriate type must be chosen according to the use, with smooth rebar (A1) available for light buildings, ribbed rebar (A2 & A3) for projects subject to higher stresses, and rust-resistant steel for areas with high humidity.

4- Suitable diameter and length

The diameter of the reinforcing steel must be chosen according to the type of structural element, as the diameters range between 8 mm and 32 mm, and the length depends on the engineering design. In columns and beams, large diameter steel is used, while smaller diameter steel is used in slabs.

5- Corrosion and rust resistance

It must be ensured that the reinforcing steel is rust-resistant, especially in coastal or humid areas, and galvanized or epoxy-coated iron can be used to protect against harmful weather factors.

6- Cost versus quality

Rebar reinforced concrete price vary according to type and specifications, so it is necessary to balance quality and cost, as cheaper steel may be of lower quality, leading to construction problems in the future.

7- Ease of forming and welding

Some projects require rebar that is easy to form and weld, so you must ensure that the steel chosen meets these requirements; To ensure ease of installation and implementation on site.

8- Availability of iron in the market

You must choose the types of rebar available in the local market. To ensure ease of supply and speedy implementation of the project without delay due to lack of materials.

9- Cohesion with concrete

Rebar with a ribbed surface should be chosen; To ensure strong bond with concrete, and reduce the possibility of separation or slippage.

 

10- Verifying quality through tests

Before using rebar reinforced concrete, quality tests must be carried out, such as tensile strength test, flexural test and concrete adhesion test; To ensure its compliance with the required engineering specifications.

Percentage of steel reinforcement in reinforced concrete

The proportion of steel reinforcement in reinforced concrete varies according to the structural factors and the nature of the project, as design loads, building requirements and the structural function of the various elements affect the determination of these proportions. The following are the general proportions according to engineering standards:

• ColumnsThe percentage of reinforcement ranges from 1% to 4% of the concrete area, and may reach 6% in some special cases according to the engineering code.
• TilesThe percentage of iron ranges from 0.7% to 1.5% of the total volume of concrete, where iron grids are used to distribute evenly.
• The beamsThe percentage ranges from 1% to 2.5%, depending on the design loads. The upper and lower iron are of different diameters to achieve optimal performance.
• Rules: The percentage of reinforcement ranges between 0.5% to 1% depending on the type of base and the design effort, taking into account the use of upper and lower layers of reinforcement to increase load bearing.

Percentage of steel reinforcement in columns

Concrete columns are among the basic structural elements that bear vertical loads and transmit them to the foundations. Determining the percentage of steel reinforcement in the columns depends on multiple factors, such as height, building type, and design loads.

But in general, the percentage can reach a minimum of 1% of the area of ​​concrete columns, while it reaches a maximum of 6% in corner columns, 5% in end columns, and 4% in internal columns.

Diameters of rebar in Egypt

Diameter is one of the basic factors that affect the strength and durability of reinforcing steel. The appropriate diameter is chosen based on the size of the structure and its structural requirements. For example:

• Iron with diameter 8mm-10mm: It is used in light applications, such as reinforcement of concrete slabs for small floors or foundations with limited loads.
• Iron with diameter 12mm-14mm: Suitable for small and medium columns, and it is also used to reinforce large concrete surfaces, such as flat surfaces.
• Iron with diameter 16mm - 20mm: Used in strong structural elements, such as foundations and columns that bear heavy weights.
• Iron with diameter 25mm - 32mm: Suitable for major construction works, such as bridges and huge structures that require high levels of strength and endurance.

Finally, steel reinforcement in reinforced concrete is an essential element in the construction sector, as it enhances the strength and durability of various structures, and in Elkady Steel and reinforcement steel agent We provide you with the finest types of rebar reinforced concrete price from major companies, such as Ezz and Al-Marakbi, to ensure that you get the best quality at the best prices.
