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 meter weight 20
If I understand correctly, then you are not interested in the weight of 20 mm reinforcement in general, but most likely the weight of one meter of reinforcement. This question could be asked in the Yandex PS a little differently: the weight of a meter of reinforcement is 20 mm, the weight of a linear meter of reinforcement is 20 mm, the conditional weight of reinforcement is 20 mm, the specific or theoretical weight of reinforcement is 20 mm, the calculated weight of reinforcement is 20 mm, and so on.
Despite the fact that these questions are formulated slightly differently, in general we are talking about the same thing. In fact, you want to calculate how much the 20 mm diameter reinforcement that you have in stock weighs, or the 20 mm reinforcement that you want to buy, but for some reason, it is not convenient for you to weigh the 20 mm reinforcement on a scale and it is more convenient to turn to reinforcement weight table. Such a table of reinforcement weights is in GOST for reinforcement.
From the reinforcement weight table, you need to find out the theoretical weight of one linear meter of reinforcement with a diameter of 20 mm.
Weight of reinforcement 20 mm diameter #8212; according to GOST
We did some not very difficult work for you, so that you do not need to download a free table of reinforcement weights or download the entire range of reinforcement, and we found the exact value of the mass of one linear meter of 20 mm reinforcement.
REINFORCEMENT WEIGHT 20 mm #8212; is 2.47 kg per linear meter.
How to use the value you found now: the weight of reinforcement 20 mm in diameter?
In fact, using the table for calculating the weight of reinforcement is very simple and convenient, although it looks somewhat #171;intimidating#187; at first glance. There are quite detailed tables of the weight of linear meta reinforcement . taking into account different types of fittings according to GOST (there are actually three of them). I'll show you with an example. So, for example, you want to buy 25 meters of reinforcement with a diameter of 20 mm.
Perhaps you need to reinforce the foundation for a fence or solve some other construction problem. When selling 20 mm reinforcement, the seller usually sets the price of the reinforcement in tons; it is in tonnage that he buys it at the factory. He sells you 20 mm reinforcement in meters, in linear meters, of which you need exactly 25 m. That is, the price of 20 mm reinforcement per ton tells you absolutely nothing.
In order to somehow convert the number of linear meters of 20 mm reinforcement you have into categories close to: price per ton of 20 mm reinforcement, you need to calculate how much your 25 meters of reinforcement with a diameter of 20 mm weigh. We find line #8212 in the table for calculating the weight of reinforcement; the weight of a linear meter of 20 mm reinforcement (we have already done this for you #8212; see above), opposite is the weight of a meter of 20 mm reinforcement in kilograms #8212; 2.47 kg.
Now, knowing the weight of one meter of 20 mm reinforcement, we must multiply it by the number of meters #8212; 2.47 x 25 = 61.75 kg. That is, your 25 linear meters weigh exactly 64.75 kg. This is the THEORETICAL WEIGHT OF A METER OF REINFORCEMENT 20 mm in diameter.
Reinforcement weight 20 mm theoretical and actual
But the actual weight of reinforcement 20 mm in diameter and its theoretical weight #8212; these are two different quantities. Unfortunately, the actual actual weight of the reinforcement never exactly coincides with the calculated theoretical weight of a linear meter of reinforcement specified in GOST. There are several reasons for this of a purely technical nature, features of the production of fittings, tolerances within a certain standard, and so on.
Therefore, when selling and purchasing 20 mm fittings, preference is ALWAYS GIVEN to the actual weight obtained when weighed on a scale. Not a single trading organization or company selling fittings will agree with the weight estimate obtained by calculation.
I won’t even mention the specifics of obtaining additional profit when selling fittings with a diameter of 20 mm, due to #171;fine-tuning the scales#187;. This is a separate topic. However, it is reasonable to practice CHECKING THE ACTUAL WEIGHT of 20 mm reinforcement by comparing the scale readings with the calculated or conditional weight of the reinforcement.
This allows you to avoid GROSS MISTAKES and significant overweighting of 20 mm fittings by an unscrupulous seller. You should always check the weight indicated by the seller of the fittings by #171;quick estimate#187; according to tabular data.

5 circles of hell: home workout to combat excess weight
The complex consists of four exercises:
- “Legs together - legs apart” with a plank position.
- Push-ups with hand touch.
- Throw on the floor.
- Leg lift.
Do each exercise for 40 seconds, and rest for the remaining 20 seconds. After resting, move on to the next exercise on the list and perform it in the same format.
Four exercises are one circuit. You need to do five in total. You cannot rest between laps, otherwise your heart rate will drop and the effect of the workout will be reduced.
If you can't do the exercise for 40 seconds and have to stop halfway through to rest, change the time to 30/30.
“Legs together - legs apart” with a plank exit
Jump on your toes, don't land on your heels. Keep your back straight and fold your arms in front of you. Try to go straight from the prone position into a squat.
If that doesn't work, jump to your hands first and then rise up into a squat.
In any case, do not rise from the squat until the end of the exercise.
Push-ups with hand touch
Push up until your chest touches the floor or close to it, tightening your abs and glutes to prevent your lower back from sagging.
If you can't do classic push-ups, do the exercise from your knees.
This exercise is performed with a medicine ball, but the no-equipment option is also a good way to raise your heart rate and engage your core muscles.
To get the maximum benefit, perform the exercise as powerfully as possible, as if you were trying to break through the floor with a heavy object or chop a log with an axe. When you swing down, push your pelvis back and keep your back straight.
Leg raise
Raise your legs and bend your knees at right angles. Lift your pelvis off the floor and lower it back. You can place your hands under it to make it comfortable.
Set a timer or do it on video with me!
Write how you like the exercises. How many laps did you do, how many seconds did you rest? And be sure to check out the other workouts. You can make a new one every day.
