Rebar is a common name for hot-rolled ribbed steel bars in decorative materials. It is a kind of ribbed steel bar, which is widely used in civil engineering construction such as houses, bridges and roads, and is an essential steel for medium-sized and above building components. Mainly produced in Japan and western Europe, but also in parts of North China and Northeast China. China imports in batches every year. Let's take a look at the theoretical weight table of rebar! How much is a ton of rebar?

A, reinforced theoretical weight table

Steel bar theoretical weight table 1

Theoretical Weight of Reinforcement Table 2

Steel bar diameter (mm) multiplied by 0.006 17 multiplied by length l; 0.6 17 is the weight of circular 10 steel bar per meter. The weight of steel bars is proportional to the square of the diameter (radius).

C/m？ =? 0.6 17*D*D/ 100

Weight per meter (kg) =? Rebar diameter (mm) × rebar diameter (mm) × 0.00 17

Note: rebar below φ 12 (including 12) and φ 28 (including 28) shall generally take three decimal places, and rebar from φ 14 to φ 25 shall generally take two decimal places.

Second, how much is a ton of rebar?

After the Spring Festival, the market has just begun to heat up. How much is a ton of rebar this year This is a concern of many steel traders and construction developers. In the steel market, the price of 6.5 high-speed wire rod is 3730 yuan per ton, the price of 8- 10 wire rod is 37 10 yuan per ton, and the price of 12- 14 secondary rebar is 3780 yuan per ton, 16 secondary rebar.

How much is a ton of third-grade rebar? The price of grade 3 rebar with specification 12- 14 is RMB 3,830 per ton, grade 3 rebar with specification 16 is RMB 3,770 per ton, grade 3 rebar with specification 18-25 is RMB 3,720 per ton and grade 3 rebar with specification 28-32. The price of construction steel such as rebar wire fluctuates frequently, and the price changes every day, which is mainly affected by inventory and steel mill output. In addition, there are rebar futures, iron ore, coking coal and other raw materials that affect rebar prices, and steel mill maintenance will also have an impact on rebar prices.

Reinforcement weight calculation formula:

Diameter d = d2/100 * 0.6 17 = d2x0.00617, where 2 is the square, and 0.617 is the theoretical weight of steel bar with diameter 10. Just write10. If the diameter is more than 12, two decimal places shall be reserved; When reserved, it is 6-7, multiplied by 0.006 17 multiplied by the square of steel bar diameter (mm).

Specific calculation method:

1, weight of square steel per meter =0.00786× side width× side width.

2. Hexagon angle weight per meter =0.0068× diameter× diameter.

3. Weight per meter of octagonal steel =0.0065× diameter× diameter

4. Weight of rebar per meter =0.006 17× diameter× diameter.

5. Weight of angle steel per meter =0.00786× (side width+side width-side thickness )× side thickness.

6. Weight per meter of flat steel =0.00785× thickness× width.

7. Weight per meter of seamless steel pipe =0.02466× wall thickness× (outer diameter-wall thickness)

8. Weight of welded steel per meter = seamless steel pipe

Remarks:

The exact calculation formulas of 1, angle steel, I-beam and channel steel are very complicated, so the approximate values are calculated by table simplification.

2.f value: 3.34 for general model and A model, 2.65 for B model and 2.26 for C model. ..

3.e value: 3.26 for general model and A model, 2.44 for B model and 2.24 for C model. ..

4. All length units are millimeters.

The above is the relevant content of the theoretical weight table of rebar, hoping to help everyone!
