# Calculate the Steel Weight

Steel is a compound of iron and carbon. Steel is made by warming iron within the sight of oxygen. Iron is a delicate, pliable metal. Adding 1.5 to 2 percent carbon makes steel, which is a more grounded yet less pliant metal. Tempered steel will be steel with differing measures of chromium added to keep rust from shaping. Cast iron is steel with a carbon content higher than 2%. It isn't pliant however can be dissolved and projected in molds.

### Unit Weight of Steel Flat Bars

The density of mild steel is 7850kg/m3. A mild steel flat bar is specified by its width and thickness in millimeters. If so, the weight of the steel bar is given by:

**Weight of steel bar** = Volume of steel Bar x Density of steel**Weight of steel Flat bar** = (Length x width x thickness) x 7850

The unit weight of MS Flat bar of width 40mm and thickness of 20mm.

**Weight of steel bar** = Volume of steel Bar x Density of steel**Weight of steel bar** = (Length x width x thickness) x 7850**Unit Weight of steel bar** = (1 x .040 x .020) x 7850

= 6.28kg/m

### Unit Weight of Steel Rods

Here, the density of steel is taken as 7850kg/m3. A mild steel round bars are specified by their diameters in millimeters(mm). If so, the weight of the steel bar is given by:

**Weight of steel bar = Volume of steel Bar x Density of steel**

**Weight of steel rod** = (Cross sectional area of steel rod x Length) x 7850kg/m3

= (3.14 x (D2 /4) x L) x 7850kg/m3

= (D2 x 6162.25L)/1000000

= D2 L x 0.006162 = D2 L / 162.28

**Weight of Steel Bar** = [ D2 L / 162.28] in Kg and Length ‘L’ in m**Weight of Steel Bar** = [ D2 L / 533] in Kg and Length ‘L’ in foot

To calculate the unit weight, length “L’ becomes unity.

The unit weight of 10mm and 12mm diameter steel bars.

The formula is :**Weight of Steel Bar** = [D2 L / 162.28]

Hence, the weight of :*10mm dia bar* = (10x10x1)/162.28 = 0.616kg**12mm dia bar** = (12x12x1)/162.28 = 0.8874kg

### Characteristics of Steel

### High Rigidity

The high elasticity offered by steel items and particularly steel support makes it ideal to reinforce solid designs. Steel build-up solid construction will offer a material that is higher in elasticity, which won't handily break under high pressure as experienced in enormous designs.

### High Compressive Strength

Steel, actually like cement, is impervious to high-pressure powers present in bigger structures a design. Together, steel and solid make for the ideal material to guarantee enduring constructions like structure, scaffolds and that's only the tip of the iceberg.

### Hard to Form and Shape

Steel isn't as simple to form and shape as new concrete, however can be formed and molded under very high temperatures. This makes it more muddled to shape and twist, yet at the same time conceivable. Steeledale Vaal can cut and twist steel support (rebar and network) nearby, part of the way on location, or totally in our own yard.

### Reasons behind the calculation of the weight of steel

In the development business, steel is regularly estimated per unit weight, like other crude materials like rock, sand, and cement. Since steel is accessible in different kinds, shapes, and sizes, valuing steel per unit weight implies a significantly more predictable evaluation across the market. This method of estimating is the reason it is vital to know the heaviness of steel all in all.

Other than that, deciding an absolute load of steel items is for the most part gainful, particularly during transport. Purchasing in mass influences the expense of most materials as we can set aside cash by appropriately coordinating conveyance and coordination as opposed to conveying little amounts in numerous excursions. Besides that, since steel can get truly hefty in huge volumes, computing the steel weight is fundamental in the plan of designs.

### Calculation Method

For MS Flat Bar

For 1-meter length of Mild Steel bar of size 40 mm width and 20 mm breadth,

Weight = Volume X Density

= width (mm) X Thickness (mm) X 7.85 Kg/mm3

= (40 X 20) X 0.00785 (converted the 7850 kg/m3 to 0.00785 g/mm3)

= 6.28 Kgs/ metre

For Circular Rebars (most used formula at site level)

The formula for Unit weight of steel = D2/162.28 Kg/m

Let’s assume,

If we want to calculate the unit weight of 8mm steel rod of 2-meter height,

Weight of steel = 82/162.28

= 0.3944 kg/m * 2m

= 0.79 kg

So 1- meter of 8 mm steel weighs around 0.79kg.

**D2/162.2 means**

Weight of steel bar per meter = Area of the steel x Density of steel x Bar length

= (3.14 x D2 /4) x 7850 kg/m3 x 1m

= (D2 x 6162.25)/(1000 x 1000)

= D2 X (0.006162)

= D2 X 1/(0.006162)-1

= D2/162.28

### Importance of Steel Weight Calculation

Steel support is a momentous advancement of the nineteenth century and has been generally utilized across the world to build up solid designs in the development business. The numerous advantages this strategy for support offers have made it a fundamental piece of the development of enormous solid constructions today.

The steel bars add solidarity to the solid construction, and take into account more specific plans, like cantilevered structures (long designs moored at just one end). It additionally empowers the utilization of more slender, less upheld solid sections, and elevates faster development times to give some examples benefits.
