To calculate the weight of a steel plate, you need to answer a couple of questions. First, what form of steel room you functioning with? among the key variables in any kind of calculation of the load of a stole plate is density. When calculating the weight of a steel plate, girlfriend can normally group stole plates into three category in terms of their densities: carbon steel plate and stainless steel, 300 series and 400 series.

The density of different species of steel plate depends primarily on its chemistry composition, which varies by small enough percentages between grades the it won’t impact the all at once density. For example, if you’re working through carbon steel, you can safely i think a density of 490 pounds/cubic feet (imperial) or 7.85 tons/cubic meters (metric) even if it is you’re working with A36 or A588.

Second, you’ll need to recognize the dimensions of the plate, including the length (L), width (W), and thickness (T). If you main point the length, width, and thickness that the plate, you will certainly arrive in ~ the volume. Law an imperial calculation, this would certainly be cubic feet; with a metric calculation, it’d it is in cubic meters.

That’s it! To calculate the weight of a steel plate, every you need are 4 pieces the information:


It’s necessary to keep in mind that any type of calculations that you arrive at using standard steel metal calculators online, or law the calculations yourselves v these numbers, need to be considered estimations. They are calculated through nominal dimensions and standardized densities. In practice, the actual metal weight might vary significantly from the estimated weight due to the fact that of variations of tolerance and composition it was observed in manufacturing.


Calculating the load of Carbon steel Plate

To calculate the weight of carbon stole plate, you’ll need to recognize the thickness, width, length, and quantity. The typical density because that carbon stole plate is 0.284 pounds per cubic inch (490 pounds/cubic feet) (imperial) or 7.85 tons/cubic meter (metric).

Depending top top the grade, Kloeckner Metals frequently supplies stole plate in widths the 48″, 60″, 72″, 84″, 96″ and also lengths the 240″ to 480″ if mill rolled (any length have the right to be noted when the plate is reduced to length, coil, or warm rolled). Thickness is additionally highly variable relying on the class but, for example, Kloeckner supplies A36 in thicknesses beginning at 3/16″ all the means up come 12″!

So, to calculation the load of an A36 discrete, mill rolled plate the is 48″ wide, 96″ long, 3/8″ or .1875″ thick, you’d calculate:

Width * size * Thickness * density = Weight48″ * 96″ * .1875″ * 0.284 lb/in3 = 245 lb.

Note it is always an excellent practice to standardize systems in any calculation. Kloeckner Metal additionally provides straightforward carbon stole plate calculator to make the calculation instant.

Calculating the weight of Stainless stole Plate (300 Series)

To calculate the weight of 300 collection stainless steel plate, you’ll also need to understand the width, length, thickness, and also quantity. The density of stainless steel 300 collection is 0.289 pounds every cubic customs (501 pounds/cubic inch) (imperial) or 7.85 grams every centimeter cubed (metric).

Kloeckner steels supplies stainless steel in qualities 304 and 304L in the hot-rolled, annealed, and pickled finish. 304 and 304 space the most commonly specified stainless steels in the manufacturing industry. They’re versatile, general-purpose stainless steels because of their an excellent corrosion resistance and formability.

Typical thicknesses of stainless steel 304 and also 304L are 3/16″, typical widths 48″ and also 60″, and also typical lengths 96″ and also 120″. So, to calculation the load of a strip mill stainless stole plate 304L the is 48″ wide, 96″ long, and 3/16″ or 0.1875″ thick, you’d calculate:

Width * length * Thickness * density = Weight48″ * 96″ * .1875″ * 0.289 lb/in3 = 250 lb.

Kloeckner Metal likewise provides an easy stainless steel plate (300 series) calculator to make the calculation instant.

Calculating the weight of Stainless steel Plate (400 Series)

The calculation for stainless steel plate in the 400 series is the very same as the rest, just with a density of 0.28 pounds per cubic customs (484 pounds/cubic feet) (imperial) or 7.8 grams every centimeter cubed (metric).

Kloeckner steels supplies stainless steel 400 series in the 409 great in the warm rolled, annealed, & pickled finish. Contrasted to carbon steel, stainless steel 409 boasts good oxidation and also corrosion resistance. You’ll often discover it in automotive exhaust systems but, because of its great weldability, formability, and also corrosion resistance, it’s used in a selection of applications.

Kloeckner Metal also provides simple stainless steel plate (400 series) calculator to make the calculation instant.

The affect of density on the weight of a stole Plate

As you can see, every else being equal, the thickness is the an enig ingredient that determines the load of a steel plate. Luckily, densities are continuous enough the you deserve to use a solitary number because that entire species of metal plates. This straightforward calculation of size * width * thickness * density is every you require for accurate, back-of-the-napkin type calculations for your next project.
