The weight of one meter of 18mm steel bar is about 2 kilograms, and the weight of steel bar per meter is calculated according to the formula of d multiplied, d represents the diameter of the steel bar, and 18 centimeters is the diameter of the steel bar, and its weight is 18 times 18 times, almost 2 kg.
Classification form of reinforcement:
1. Diameter size.
According to the diameter, the steel bar is divided into steel wire with a diameter of 3-5mm, thin steel bar with a diameter of 6-10mm, and thick steel bar with a diameter of more than 22m.
2. Mechanical properties.
According to the mechanical properties, the steel bar can be divided into 235 420 grade steel bar, 335 455 grade steel bar, 400 540 grade steel bar and 500 630 grade steel bar.
3. Production process.
According to the production process, there are hot-rolled steel bars, cold-rolled steel bars, cold-drawn steel bars, and heat-treated steel bars after heat treatment of grade steel bars.
Reinforcement weight calculation:
The unit of measurement for calculating the theoretical weight of steel is kilograms (kg). The basic formula is: w (weight, kg) = f (cross-sectional area m2) l (length, m) density, g cm3) 1000.
The density of steel is:, and the formula for calculating the theoretical weight of rebar is as follows: w=. d = cross-sectional diameter mm, such as cross-sectional diameter of 12mm rebar, weight per meter =.

Rebar with a diameter of 18mm weighs kilograms per meter.
Simple calculation: d d diameter multiplied by diameter.
Formula: 1, m a·l· 1000 r l 1000m r l 1000 ;
2、m=a·l·ρ/1000=π×d²/4×l×ρ/1000=πd²/4×l×ρ/1000。
m=π×d²/4×l×ρ/1000=。

In general calculation, the reinforcements below 12 and 28 are taken to 3 decimal places, and the reinforcements from 14 to 25 are taken to 2 decimal places.

Each meter with a diameter of 18 is 2 kg.

The weight of 18 steel bars per meter is 9 kg. If it is a No. 16 steel bar, the theoretical data can be obtained according to its weight calculation formula is about kilograms. And the so-called 16 steel bar, that is to say, its diameter is 16 mm, belongs to a kind of round steel.
If it is a threaded bar, it will weigh slightly more because there are ribs in the bar, which will increase the weight.
When it comes to understanding the weight of the rebar, you can go directly to a table of the theoretical weight of the rebar.
It can also be approximately drawn. For example, in construction projects, the commonly used ordinary steel bars, the smallest weight is No. 3 steel bars, the weight is kilograms.
Data analysis. No. 4 rebar, No. 5 rebar, No. 8 rebar, No. 10 rebar, etc., the larger the model, the weight of the steel bar will gradually increase. For example, the theoretical weight of No. 38 steel bar is close to 9 kilograms.
Because the steel bar is also bent and dismantled and divided into different divisions, such as flat bars.
Their weight is the width of the jujube multiplied by the thick distance, and at the same time, it must be multiplied by a certain coefficient, which is.

The square of the diameter of the rebar is multiplied by the weight of the rebar per meter, and understood!
-
As far as I understand, the weight of one meter of 18mm steel bar is kilograms. 1 meter.
The weight of the rebar = the diameter of the rebar * the diameter of the rebar. -
In general calculation, the reinforcement below 12 and 28 is taken to 3 decimal places.
The reinforcement from 14 to 25 is 2 decimal places.

Summary. The weight of 18 steel bars per meter is 9 kg.
The weight of 18 steel bars per meter is 9 kg.
The density of the reinforcement is: The minimum standard for the density of building steel bars is grams of cubic centimeters = tons of cubic meters = kilograms (kilograms are eliminated) and decimeters. The unit of measurement for calculating the theoretical weight of steel is kilograms (kg).
Rebar is steel for reinforced concrete and prestressed reinforced concrete, with a circular cross-section and a square with rounded corners when there is a finch pose. It includes round steel bars, ribbed steel bars, and torsion steel bars.
The classification of rebar includes bare round rebar, ribbed rebar, and torsional rebar.

Kiss, 18 steel bar one meter of 2 kilograms 18 centimeters of steel bar one meter of weight is about kilograms, the weight of steel bar per meter is calculated according to the formula of d square times this formula, d represents the diameter of the steel bar, and 18 cm is the diameter of the steel bar, its weight is 18 times 18 times, almost the world or there are kilograms. The reinforcement of 18 represents the diameter of the cross-sectional circle of 18 mm, the radius of 9 mm, and the length: 1 m 100 cm.
Cross-sectional area s square millimeters square centimeters. Rebar volume v sx length cubic centimeters. The weight of the rebar is equal to the density multiplied by its volume.
g g 2 kg. The steel bar is 1 meter long and weighs 2 kg. I hope my cousin can help you.
If you have anything to consult, you can send me Yuanhuichun, I will reply to you as soon as possible, I wish you a happy life.

The weight of 18 threaded silver rolling steel bars is about kilograms.
The formula can be used where the weight of one meter of threaded reinforcement is equal to the square of the diameter multiplied by the density, i.e., 18 times 18 times approximately equal to kilograms per meter. However, there is still an error between the calculated value and the actual weight, so this value can only be regarded as a reference.
Tips for buying rebar.
1. Check the surface quality of the steel bar.
The surface of the high-quality steel bar is smooth and flat, the color is uniform and dark blue-gray, no cracks, scars and other defects are visible, and the end face of the steel bar is round. The end face of the inferior steel bar is oval, the surface is rough and uneven, and the iron oxide crumbs produced during rolling are knocked or wiped off.
2. Check the signs of the steel bars.
Look at the rebar sign with the factory name, sign, quality front stop certificate, brand mark, implementation standard, product grade, specification, batch number and other content, and indicate the production license number and QS mark. According to the standard, it is also necessary to affix a special official seal for quality certification. Formal enterprise steel packaging, signs, certificates, etc. are more complete, if consumers encounter small bundles of packaging or bulk, no quality certificate of steel bar, it is recommended not to buy.
