How much does one rod of 12 reinforcement weigh

Reinforcement 12: Calculation, weight, price

Calculation of the amount of reinforcement. Cost of one meter. Characteristics and GOSTs.

The choice of diameter of rod reinforcement for reinforced concrete structures depends on the load and operating conditions of the object. Starting from 12 millimeters and above, rods are used for load-bearing supports, walls, foundations, building frames, floors, highways, and bridges with significant loads. It is reinforcement 12 that is most in demand in construction. This is due to its high-quality physical characteristics and favorable price.

Steel grades for 12 mm GOST bars

Production is based on the hot-rolled method of producing shaped metal products. According to their technical properties, products are divided into prestressed and non-tensioned. Prestressed ones make it possible to achieve high bending strength, which is important in structures with pronounced lateral pressure. This type of rod is most often made from the following grades of carbon and low-alloy steel:

st3, 32G2Rps, 25G2S, 35 GS.

Requirements for steel and assortment for rods d=12 are regulated by: GOST 10884-94, GOST 5781-82. In a concrete structure, reinforcement 12 enhances the strength properties of the finished building.

At the same time, the rods themselves take certain loads and protect the frozen block, for example, a foundation, from concrete cracking during its hardening and operation. This is the main purpose of using rods.

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).

Features of a periodic profile

Rods of this parameter are produced with a smooth or corrugated surface. Continuous profile rods (corrugated) have undeniable advantages when protrusions are located in a spiral or along the axis of the rod. In the marking, the designation of the diameter of such rods means the average data of 2 values:

Internal (implies the diameter of the rod body only);
External (indicates the size of the entire diameter, with protrusions).

Parameters: diameters, area, weight, length

Rods of 12 millimeters have a rod body d (internal) of 11.3 mm; d external 13.7 mm. The cross-sectional area is 1.131 cm2. The weight of 1 meter of profile is 0.888 kg. 1 ton contains 1126.13 m of product.

Slicing and packaging

Production is possible in 2 ways: hot-rolled and cold-formed. Rods are produced from ferrous rolled products using the hot-rolled method, and from non-ferrous metals - using the cold-rolling method. The price of the rods depends on this parameter, regardless of the method of cutting rolled metal:

Rods of measured length;
Profile of unmeasured length in packs.

12 mm reinforcement is packaged in bundles, the range of rod lengths is 6-12 meters. However, by agreement, it is possible to cut the rods into segments of any length from 3 to 25 m. Standardly, 1 rod of reinforcement is cut to a length of 11.75 m. From here you can calculate its weight, which at this length will be 10.43 kg. At the same time, a ton of profile contains 1126 meters.

Reinforcement calculation 12

To calculate how many meters of rods are needed, the total mass is divided by the weight of one meter. It is important to know that rods have theoretical and actual weights, which differ due to the fact that the values are standardized within certain tolerance ranges. 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.

In order to find out the actual weight of the released rods, a control weighing of the total tonnage of the batch is carried out directly during loading. It should be noted that the maximum deviations that regulate weight are also indicated in the standards. If 12 mm reinforcement is weighed, these deviations can range from -6% to +5% according to GOST 5781-82.

Smooth profile

Smooth rods for construction are produced by the hot-rolled method, hardness class A1. Products are cut, as agreed with the customer, either standardly or to custom lengths. 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 also applies to corrugated products.

Price of fittings dn=12 mm

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. In this case, the customer can receive cuts of any length. 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.

In the Moscow region, 1 meter of reinforcement with a nominal diameter of 12 costs from 24 rubles (periodic profile).

Smooth profile, price per 1 meter:

From 29 rubles (retail);
From 28 rub. small wholesale;
From 27 rub. large wholesale

The price of reinforcement per ton is from 25,900 rubles (grade A500/35GS) with a standard cut of 11.7 m. With a rod length of 6 meters - from 26 thousand rubles. subject to the purchase of a wholesale batch of 20 tons.

The cost of one meter with a rod length of 3 m is 28 rubles. The lowest price per meter is 21.5 rubles. with standard cutting 11.7 m (A3, A500C). Reinforcement with a nominal diameter of 12 millimeters is used mainly for reinforcing high-grade concrete.

Reinforcement beam mass

Aluminium, duralumin
Copper, bronze, brass
Tin
Lead
Zinc

To reinforce the beams, 2.5 tons of 25-diameter rods are required. Therefore, knowing the weight of the reinforcement will also not be superfluous when calculating the pressure of the structure on the foundation - several unaccounted tons of load can have a detrimental effect on the reliability and durability of any building.

All data indicated in this table fully comply with the current GOST. Reinforcement is an important component of such structures - non-reinforced concrete, although it can withstand significant compressive loads, practically does not work in bending and tension, collapsing under relatively small loads. The specialist knows how much material he needs, and also knows the optimal diameter.

A table of reinforcement weights will help them with this.

Reinforcement beam mass

As you can see, the difference is huge. The larger the diameter, the greater the weight. In this way, you can count the number of rods with any cross-section. You will find it below in the article, in the reinforcement table, the value of the mass of metal rods of all diameters is presented. Of course, first of all, the mass of the rod depends on the thickness.

But it’s difficult to calculate how long a certain mass of material will last if you don’t know how much a meter of reinforcement weighs. The opposite situation may also occur. How much does the fittings weigh? To do this, we take the entire mass of the necessary rods and divide them by the weight of 1 linear meter.

Next, we convert tons to kilograms, multiply by 1000, it will be 2500 kg, and divide by 3.85, we get 649 meters of material.

Often builders find themselves in situations where they need to know the weight of reinforcement in order to calculate the required amount of material for construction.

Having found out the theoretical weight of a meter of reinforcement, he just needs to multiply this number by the total length of the required metal rods to determine how much material is needed for construction.

Why do you need to know the weight? Professional builders often have a question: what is the weight of a linear meter of reinforcement. Knowing the total mass and specific gravity of the reinforcement, 1 meter, you can make simple calculations in a matter of seconds, obtaining the total length of the metal rods.

In order to find out the reinforcement weight, the easiest and most convenient way is to use the special table presented below.

But the use of metal rods - regular or prestressed - eliminates this drawback. Weight of reinforcement: table of weight of 1 linear meter of all diameters. The standard length of a metal rod is 11.7 m, to find out the required number of rods, divide 649 by 11.7, we get 55.5 pieces. What does the mass of rods depend on? Today, in construction, metal rods with a diameter of 6 to 80 millimeters are most often used.

This will help, especially in private construction, to check that the correct amount of material has been delivered to you. The error can be a maximum of a few percent - such errors will not cause significant trouble and will certainly not cause damage to the structure.

Having a table at hand, you can quickly calculate the weight of reinforcement, for example, with a diameter of 32 mm. Find the corresponding diameter in the first column and immediately find out that its mass is 6.32 kg per 1 m, and a ton includes 158.48 meters. Reinforcement weight table.

Why do they need this?

The fact is that when purchasing rods for the construction of large structures, it is not purchased individually, as in individual construction, but in tons.

The weight of 1 m of reinforcement, the thinnest, weighs only 222 grams, while for the thickest this figure is 39.46 kilograms. Calculation example. We take the value of the mass of 1 meter from the table, equal to 3.85 kg.

Reinforced concrete today is the most common material used in the construction of multi-story buildings, roads, tunnels, bridges and any other objects.
