How important is knowing the weight of steel plates?

Steel is a common material that is typically priced per unit weight, just like gravel, sand, and concrete. The weight of steel is calculated to ensure consistent pricing in the market, considering that steel is available in various types, shapes, and sizes. When purchasing steel plates, calculating the total weight of the products helps us plan the transport from the supplier's warehouse to the project or fabrication site efficiently. Additionally, knowing the weight of the steel plates used in a project can help us determine if we can lift the final product safely. As demonstrated in the sample computation of steel weight, understanding the weight of steel plates is vital for project planning and execution.

How to measure steel plate weight?

To calculate the weight of a steel plate, it is important to know the density of the steel alloy that the plate is made of. This information is readily available in our steel plate weight calculator, which provides the densities of the most commonly used steel alloys. Our calculator also includes a table that lists the density of each steel type or alloy for reference purposes. By inputting the dimensions of the steel plate into our calculator and selecting the appropriate steel type, one can quickly and easily determine the weight of the plate.

Weight = Volume x Density

In the case of steel plates, the formula for calculating their weight is:

Weight (in kilograms) = Volume (in cubic meters) x Density (in g/cm³) x 1000

The resulting weight will be in kilograms since we used the density in grams per cubic centimeter and multiplied it by the volume in cubic meters. Knowing the weight of our steel plate is crucial, especially when we need to transport or lift it, and it helps us in planning and estimating the cost of our projects accurately.

To better understand how to calculate the weight of a steel plate, let's consider an example. If we have multiple steel plates of the same dimensions, we can input the number of plates into our steel plate weight calculator to obtain the total weight of all plates. This process involves determining the density of the steel alloy, obtaining the total volume of the plate, and multiplying this volume by the steel plate's density. By following these steps, we can accurately calculate the weight of our steel plates and properly plan for their transportation and use in our projects.

How does the steel weight plate calculator work?

Let's consider an example to understand how to calculate the weight of steel plates. Say we want to build a mold for cube-shaped concrete blocks and we need to cut 5 squares, each with 20 cm sides, from a 1-cm thick mild steel plate with a density of 7,870 kg/m³. The illustration below shows the dimensions of the squares we need to cut from the steel plate:

To determine the weight of the cut steel plates, we can start by calculating the volume of the steel plate. Since we know that the density of mild steel is in kilograms per cubic meter, we can calculate the steel plate volume in cubic meters by multiplying its dimensions together. In this example, the side length of the square plate is 20 cm or 0.2 meters, and the thickness is 1 cm or 0.01 meters. Therefore, the volume of a single piece of square plate can be calculated as follows:

steel plate volume = 0.2 m × 0.2 m × 0.01 m

steel plate volume = 0.0004 m³

Solving for weight, we have:

steel plate weight = steel plate volume × density

steel plate weight = 0.0004 m³ × 7,870 kg/m³

steel plate weight = 3.148 kilograms

However, since we need five pieces of this square steel plate, the steel plates' total weight would then be 3.148 kg × 5 = 15.74 kilograms. That's a lot of weight for just a small piece of cube mold!
