How much does 12 mm reinforcement weigh - Metals and their processing

Reinforcement weight 12 mm per meter

Reinforcement in construction is an important component when installing foundations and other supporting foundations. At the design stage, engineers calculate the required quantity based on the magnitude of the influencing forces and loads. As a rule, this preliminary calculation is made in meters. Suppliers almost always supply products in kilograms. In this regard, there is a need to quickly and accurately determine the weight of 12 mm reinforcement per meter.

General information

The fittings are pieces of rod with a ribbed surface. Thanks to these ribs, it is able to withstand higher bending loads compared to conventional rods. In most cases, bars are made from steel designed specifically for reinforcement.

To calculate weight per unit meter, use the following methods:

Online calculator.
Special tables.
Formulas of geometry and physics.

Let us now examine each point in more detail.

Online calculator

This is the easiest way to find out the weight of any rolled product. Online calculators are specially written programs for calculating the weight of reinforcement per unit meter. To make the calculation, you only need to enter the diameter of the rod and its length, and the program will calculate the weight itself.

The advantage of an online calculator is accuracy and speed. The downside is the need for a computer or other digital device connected to the Internet.

Finding these programs on the World Wide Web is not difficult. They are usually free and built into the website of most rental suppliers (circles, channels, etc.).

Reinforcement weight determination table

The second method is to use tables to find the mass of a rod per 1 meter. They are freely available on the Internet or can be found in special reference books on a variety of building and other materials.

The table shows the mass of one linear meter of reinforcement of a given diameter. To find this value, you simply need to correlate the readings indicated in the rows and columns. Next, this number is multiplied by the number of meters we need and that’s it. Weight found.

How to find weight using formulas

In situations where there is neither the Internet nor a table at hand, the use of special formulas based on simple physical laws can help calculate the weight of reinforcement. The dependence of weight on length is as follows:

Weight of reinforcement = density*3.14*(radius of reinforcement)2*length

Steel reinforcement has a density of 7850 kg/m3. The radius is equal to half its diameter. When calculating weight, you should pay attention to the dimension. For greater clarity, let's consider a specific example.

This gives reinforcement with a diameter of 12 millimeters and a length of 10 meters. First, let's determine the radius. To do this, we convert it to a unit of meter and divide by 2. We get a value equal to 0.006 m. Then we simply substitute everything known into the formula:

Weight of reinforcement = 7850*3.14*0.006*0.006*10=8.8 kg

As you can see, this method is not complicated.

It is also worth considering that the actual weight of the reinforcement is always slightly different from the theoretical one. On average this is plus or minus 5%. The reason for this is that the rod itself has a slight deviation in size due to non-ideal production.

Fiberglass reinforcement

What is good and what is not so good. Metal reinforcement, as an obligatory component of virtually the entire range of reinforced concrete products, is perhaps the only building material that until recently had no alternative.

However, technological progress and the achievements of modern science in the field of construction have managed to break this stereotype.

In the seventies of the last century, the first tests of composite reinforcement took place and their results gave reason to assert that a worthy replacement exists and has a great future.

View from the outside

Externally, metal and fiberglass reinforcement are very similar. Meanwhile, there is a significant difference between them. For example, by color. So the silver and, often, rusty color was replaced by a material with a definitely more positive visual perception.

Let us note right away that yellow, beige, black, green, blue and other colors are in no way gradations of the material according to one or another indicator and depend only on the preferences of the manufacturer.

On a note

Today there is an opinion on the market that fiberglass reinforcement of certain colors is of higher quality or more durable. We dare to dissuade you of this. Such a wide palette is nothing more than a marketing ploy by trading organizations. In other words, the color of composite reinforcement does not have any influence, nor does it participate in the gradation of the qualities and properties of a given material.

Fiberglass reinforcement: quality and structure

The basis of the composite reinforcement material is fibers:

Basalt;
Carbon;
Glass;
Armid.

The binder for each type is complex polymers. It is their merit in the strength, ductility and other performance properties of fiberglass reinforcement.

In cross-section, fiberglass reinforcement can have either a circle or a circle with glass spiral winding. The standard winding pitch is 15 mm. The second option demonstrates greater adhesion to concrete and cement mortars and is therefore a priority for builders.

Fiberglass reinforcement: physical and performance qualities

Speaking about the advantages of composite reinforcement for foundations, let's start by listing them:

It has a lower specific weight (as a clear example, we point out that one meter of steel reinforcement weighs the same as nine meters of carbon fiber reinforcement);
Does not corrode and therefore does not destroy reinforced concrete structures;
Does not conduct electric current (valuable both during installation and operation);
Does not create radio interference;
Not a heat conductor;
Economical in financial terms;
Has unlimited length (within reasonable limits, of course);
Compact (if necessary, can be transported in coils;
The manufacturer guarantees 80 years of trouble-free operation;
Resistant to chemical influences;
Has an attractive aesthetic appearance.

On a note

Since metal reinforcement in reinforced concrete products is replaced with composite reinforcement, in everyday life their names are also replaced with fiberglass reinforced concrete.

Composite reinforcement

Fiberglass reinforcement: application and installation

Installation of composite reinforcement during the construction of foundations is carried out similarly to metal reinforcement. When constructing a frame structure, the rods are fastened using wire twists or special staples (ties).

Let us add that when installing foundations, it is allowed to use carbon fiber mesh, individual rods and classic frames - all this refers to discrete reinforcement.

Dispersed allows for the direct addition of reinforcement scraps to concrete. Such reinforcement is used mainly in the construction of unloaded foundations.

The areas of application of alternative reinforcement extend to almost all areas of the construction of low-rise buildings and objects for various purposes, and especially to their foundations. The concrete poured into such foundations is called glass fiber concrete.

A separate branch of the use of non-metallic fittings can be called the arrangement of the adjacent space. This:

Fences of flower beds, greenhouses and front gardens;
Supports for individual flowers, shrubs and trees in the garden. Here, the color scheme of composite rods is of particular relevance;
Composite rods are readily used in the construction of walls and partitions from gas and foam concrete blocks .

Fiberglass reinforcement screed

We choose, we calculate, we don’t make mistakes

State standard 31938-2012 regulates the main dimensions of non-metallic reinforcement, indicating both absolute values and numbers of compliance with the classics - steel reinforcement.

One of the main differences between steel and plastic reinforcement bars is its geometry. If the metal one has a cross-section close to a circle, then the carbon fiber one has a cross-section close to an oval. In this case, the smaller size is called the “internal diameter”, and the larger one is called the “external diameter”. This is where difficulties begin in determining the required size. The generally accepted way out of this situation is to calculate average values.

On a note

Any options for one or another selling organization to convince you of a different payment procedure is a surefire reason to turn to their competitor.

As a clear example, we provide a comparison table for some ranges of fittings

Steel fittings GOST 5781-82	Composite reinforcement GOST 31938-2012
Diameter, mm	Sectional area, sq.mm	Tensile strength N/sq.mm	Inner diameter, mm	Sectional area, sq.mm	Tensile strength N/sq.mm

14	154	390	10,71	90,5	1100
16	201	390	11,92	111,33	1100

What is priority - fiberglass or steel?

This question is not simple and the answer to it most likely needs to be sought in a comparison of the main parameters. We will try to achieve certainty on this issue. So,

Metal rods have elasticity and plasticity, while composite products have only elasticity;
In terms of tensile strength, non-metallic products are several times higher than steel ones: 1300 and 390 MPa;
Thermal conductivity coefficient for fiberglass: 0.35 W/m*C0 – and 46 for steel;
The density of steel reinforcement is 7850 kg/m3, composite reinforcement is 1900 kg/m3;
Fiberglass products are not afraid of corrosion, while for a competitor made of steel this is a real scourge;
Fiberglass reinforcement is neutral to electric current, does not magnetize, which means it is ideal for rooms with radio equipment, and cannot be replaced in the construction of laboratories and technical centers;
Fiberglass reinforcement practically does not bend, which limits its use in reinforcing floor slabs and other concrete products;
As a result of the supply of non-metallic reinforcement in rolls, cost overruns during purchase and waste during installation are practically guaranteed.

Thus, with all the unique characteristics and physical indicators of composite reinforcement, we recommend using it for foundations with a great degree of caution. The use of non-metallic reinforcement for heavily loaded structures and areas where there is a high probability of destruction is prohibited. As for all other construction sites, here composite reinforcement has already confirmed its effectiveness and is the undisputed favorite.

Smooth profile. From here you can calculate its weight, which at this length will be 10.43 kg.

Reinforcement with a nominal diameter of 12 millimeters is used mainly for reinforcing high-grade concrete. In this case, the customer can receive cuts of any length. Rods of this parameter are produced with a smooth or corrugated surface.

The price of rod reinforcement is indicated per linear meter and per ton; more often, the manufacturer indicates the cost per ton based on the finished length of the segments.

How much does 12 mm reinforcement weigh?

It should be noted that the maximum deviations that regulate weight are also indicated in the standards. In a concrete structure, reinforcement 12 enhances the strength properties of the finished building.

In the marking, the designation of the diameter of such rods means the average data of 2 values: Internal (implies the diameter of only the rod body), External (indicates the value of the entire diameter, with protrusions). 1 ton contains 1126.13 m of product.

The price of the rods depends on this parameter, regardless of the method of cutting rolled metal: Rods of measured length, Profiles of unmeasured length in packs. The cost of one meter with a rod length of 3 m is 28 rubles. Features of a periodic profile.

This type of profile has no protrusions or ribs. Welded steel reinforcement has the ability to be welded efficiently without loss of tensile and bending strength. This is the main purpose of using rods. According to their technical properties, products are divided into prestressed and non-tensioned.

Starting from 12 millimeters and above, rods are used for load-bearing supports, walls, foundations, building frames, floors, highways, and bridges with significant loads. With a rod length of 6 meters - from 26 thousand rubles. subject to the purchase of a wholesale batch of 20 tons.

How much does reinforcement weigh 12

The choice of diameter of rod reinforcement for reinforced concrete structures depends on the load and operating conditions of the object. In the Moscow region, 1 meter of reinforcement with a nominal diameter of 12 costs from 24 rubles (periodic profile). Steel grades for 12 mm GOST bars.

Prestressed ones make it possible to achieve high bending strength, which is important in structures with pronounced lateral pressure.

And this type is advantageous due to its high-quality physical characteristics, suitable for the loads of low-rise residential buildings, and an attractive price (compared to higher and more expensive brands).

Rods of 12 millimeters have a rod body d (internal) of 11.3 mm, external d of 13.7 mm. If 12 mm reinforcement is weighed, these deviations can range from -6% to +5% according to GOST 5781-82.

This type of rods is most often made from the following grades of carbon and low-alloy steel: Requirements for steel and assortment for rods d=12 are regulated by: GOST 10884-94, GOST 5781-82.

Smooth rods for construction are produced by the hot-rolled method, hardness class A1. To calculate how many meters of rods are needed, the total mass is divided by the weight of one meter.

Products are cut, as agreed with the customer, either standardly or to custom lengths. The cross-sectional area is 1.131 cm2. At the same time, a ton of profile contains 1126 meters. Parameters: diameters, area, weight, length.

That is why the weight when releasing products may differ slightly, up or down from that stated in GOST 5781-82 for one linear meter and the entire order as a whole.

Knowing how much 1 ton will cost and the number of meters in it, you can calculate what the price is for 1 meter of rods.

How much does 12 mm 11.7 m reinforcement weigh?

Rods are produced from ferrous rolled products using the hot-rolled method, and from non-ferrous metals - using the cold-rolling method. 12 mm reinforcement is packaged in bundles, the range of rod lengths is 6-12 meters. Production is possible in 2 ways: hot-rolled and cold-formed.

The price of reinforcement per ton is from 25,900 rubles (grade A500/35GS) with a standard cutting of 11.7 m. Cutting and packaging. Continuous profile rods (corrugated) have undeniable advantages when protrusions are located in a spiral or along the axis of the rod.

This is due to its high-quality physical characteristics and favorable price.

Reinforcement 12 mm

Reinforcement rod weight 12 mm

For a long time I gathered my courage to start building my own country house. To carry out the work of pouring the foundation, it was necessary to use a large amount of reinforcing bar with a diameter of 12 millimeters. I immediately had a question about how much 12 mm reinforcement weighs, but I will write about this below.

Reinforcement and concrete #8212; inseparable

Getting acquainted with various country house construction projects on the Internet, I saw that a large number of house elements are made of monolithic concrete. It is these structures that require the expenditure of materials for reinforcement.

The weight of the reinforcing bars required for reinforcing the structure is calculated by multiplying the total length of the entire reinforcing bars by the weight of one linear meter of reinforcement.

The weight of one linear meter of reinforcing bars is a constant unit. The weight of a linear meter of reinforcing bars depends on the composition of the steel used in the manufacture of the reinforcement, as well as on its cross-section.

Knowing the mass of the reinforcing bars, you can estimate the degree of reinforcement of the structure, which depends on the ratio of the mass of the reinforcing bars to the volume of concrete used when pouring the structure. By the way, you can simply use an online calculator for the foundation.

Important! The degree of reinforcement allows you to calculate the cost of the structure.

How much does the fittings weigh?

The weight of a meter of reinforcing bars with the same steel alloy composition completely depends on the diameter of the reinforcing bars and the cross-section of the reinforcing bars.

With a diameter of reinforcing bars equal to three millimeters and a cross-sectional area equal to 0.071 square centimeters, the specific weight of such reinforcement is 0.055 kilograms per linear meter.

With an increase in diameter by one millimeter, the cross-sectional area is 0.126 square centimeters, and the weight of one meter of such reinforcement is approximately 0.098 kilograms per meter.

With a diameter of a metal reinforcement bar of five millimeters, the cross-sectional area increases to a value equal to 0.196 square centimeters, while the weight increases to a value equal to 0.154 kilograms per meter.

When using reinforcement with a diameter of six millimeters, the cross-sectional area is 0.385 square centimeters, while the mass of one meter is 0.222 kilograms per meter. In principle, this can be found out from the reinforcement weight table.

How much does a meter of 12 mm reinforcement weigh, required for constructing a foundation?

The construction of houses involves the construction of the foundation of the building, so different foundation designs are erected. Depending on the material from which the house is built, one or another type of foundation is suitable. One of the main elements of the base is the reinforcement strapping, which gives strength and flexibility to the concrete structure.

The most common metal rod for foundations is 12 mm reinforcement. You cannot underestimate the dimensions, because this indicator is already minimal. Before installing formwork and pouring the foundation, it is necessary to calculate the number of metal products that need to be delivered to the site.

In this regard, the question arises: how much does a meter of reinforcement with a 12-mm section weigh?

Types of metal rods for foundations

Reinforcing metal products are manufactured in accordance with GOST, which is a regulatory legal act of the Russian Federation and obliges manufacturers and developers to adhere to the required parameters specified in the document.

To determine how much a meter of reinforcement-12 weighs, you need to know what types of products are produced. There is hot-rolled steel with 6 strength classes, thermomechanically hardened steel, welded steel and composite polymer reinforcement.

The latter is the lightest in weight of all the others, if we take the same diameter for comparison, because it is made of a special lightweight material.

How to calculate weight

To determine how much reinforcement-12 is in a ton, three methods are used. First, you can weigh one or more rods of the same diameter and a certain length. After this, divide the ton by the weight result and calculate the quantity. The second option is designed for use in calculations of the nominal diameter of the product, which is equal to the cross-sectional size of a smooth rod.

The third way to solve the simple problem of how much a meter of reinforcement-12 weighs is to use tables with standard technical indicators to determine the weight according to the diameter of the metal product.

Such data is determined by GOST, thanks to which you can quickly find out the quantity per ton, based on the type, type of product, as well as taking into account the material used for manufacturing.

Using GOST in calculations

Metal rods can be smooth or corrugated. With the former, the situation is simpler, because the diameter is the same throughout the entire length of the product. Corrugated ones, in contrast, have a non-uniform surface, which makes it difficult to calculate their weight.

The regulatory document provides different tables defining the diameter of the rod, its weight depending on the strength class, the metal used, the hardening process, rolling, etc. As a result, in order to find out how much a meter of reinforcement-12 weighs, it is necessary, in addition to the diameter, to take into account some indicators.

GOST indicates that a product with a diameter of 12 mm has a minimum diameter between the ribs of 11 mm, and a maximum diameter on the edge of 13.5 mm. Based on these indicators, the estimated area of this product has already been worked out, which is 1.13 cm2. The following is a summary and it turns out that a linear meter of 12 reinforcement has a weight of 0.89 kg.

It turns out that 1 ton of rolled metal contains 1,123.60 meter-long rods to create a strong, reliable foundation. If 12 mm reinforcement is not used, but a larger diameter is taken, then the number of rods, accordingly, becomes smaller.

Why are such calculations needed?

Design and construction are important stages in creating a safe home and the people living there. Calculations become necessary so that every step on a construction site is accurate and correct. The amount of required reinforcement is needed to calculate the strength of the foundation and will allow delivery to the construction site by specialized transport in the required quantity.

And this will at least reduce transportation and loading costs, and reduce labor costs. Therefore, any, even small, construction must involve advance design and calculation of the required material. This is not just about reinforcement; this rule applies to any type of building material, be it brick, block, wood, or even linoleum, laminate, or wallpaper. Everything has an account, because...

Today you have to pay for every centimeter and kilogram.
