Rebar: Types, Diameters, and GOST Standards. What You Need to Know Before Buying

Reinforcement is one of the essential building materials, essential for constructing durable reinforced concrete structures. The reliability of the entire building depends on the correct choice of type, diameter, and grade of steel. In this article, we'll discuss the different types of rebar, the most commonly used diameters, the GOST standards it complies with, and the factors that determine the price per meter of 10mm rebar.

What is reinforcement and why is it needed?

Rebar is a metal rod used to reinforce concrete structures. Concrete withstands compression well but has poor tensile strength, so rebar compensates for these loads, ensuring strength and durability.

It is used almost everywhere:

• in the construction of foundations, slabs and columns;

• for pouring floors and ceilings;

• in the manufacture of stairs, fences, lintels and other elements.

Main types of reinforcement

Depending on their purpose, reinforcement is divided into several types:

1. Working reinforcement — bears the main loads in the structure.

2. Assembly — used for fixing and assembling the frame.

3. Distribution - evenly distributes the load between the elements.

4. Clamps and ligaments - auxiliary parts that hold the rods at a given distance.

In addition, according to the manufacturing method, reinforcement can be:

• Hot rolled (class A240, A400, A500);

• Cold-formed (class B500);

• Composite - fiberglass or basalt-plastic, lightweight and corrosion-resistant.

Rebar diameters and where they are used

Rebar is available in diameters ranging from 6 to 40 mm. Each size has its own purpose:

• 6–8 mm — lightweight frames, road slabs, small structures;

• 10–12 mm — private construction, reinforcement of floor slabs, floors, stairs;

• 14–18 mm — load-bearing walls and columns;

• 20 mm and more - industrial and monolithic buildings.

The most popular is considered to be 10 mm reinforcement - It is universal and suitable for most construction tasks. At the same time 10mm rebar price per meter depends on the steel grade, production method and current metal prices.

GOSTs and standards

The production of reinforcement in Russia is regulated by several key standards:

• GOST 5781-82 — for hot-rolled reinforcement of periodic profile;

• GOST R 52544-2006 — for reinforcement class A500C;

• GOST 10884-94 — for thermomechanically hardened steel;

• GOST 31938-2012 — for composite reinforcement.

Compliance with these standards guarantees the accuracy of geometric parameters, strength and reliability of the material.

What determines the cost of reinforcement?

The price of reinforcement is determined based on the following factors:

1. Diameter and weight of the rod. The larger the diameter, the higher the price per meter.

2. Steel grade. More durable brands cost more.

3. Type of reinforcement. Composite is cheaper, steel is stronger and heavier.

4. Region of delivery and purchase volume. For wholesale orders the price is reduced.

5. Metal price on the market. The cost of raw materials directly affects the final price.

Conclusion

Rebar is the foundation of any reliable structure. When choosing, it's important to consider the strength class, diameter, and compliance with GOST standards. For private construction, 10mm rebar is the optimal solution, combining strength, versatility, and affordability.

If you're planning to purchase 10mm rebar for construction work, check with your supplier for the price per meter: prices may vary depending on the batch, region, and delivery terms. Properly selected rebar is the key to the durability and safety of your facility.
