What is a plate?

A plate is a flat, thin, usually rectangular sheet of metal or other rigid material used in construction. You can get a plate by rolling or forging certain flexible materials. They are typically used to cover the space between joists or studs to form a continuous, flat surface that the other building components are attached to. You can use different materials for the plates, but steel is often the best choice for material. 

Some types of plate steel you can use in the construction of buildings. The others are used in the creation of everyday items. The construction steel plate is a versatile, customizable, and durable solution for any construction project. This product is created to fit your needs using either high-quality stainless steel or aluminum. Therefore, the high-quality stainless steel is extremely durable and resistant to rust, perfect for long-term use. The aluminum option is lighter and less expensive, great for temporary use.

Specifically, flats are extruded bar products that are adaptable and have a broad scope of applications. You can use the flat bar for all fabrication projects where lightweight and corrosion resistance is a concern. Aluminum flat bar stock. Often, you can use a plate for durability and strength and a flat bar in ornamental fabrication.

Plate properties

Wood plate materials are made by gluing wood raw materials of different types, qualities, and shapes. We distinguish two basic types of wood plate: plywood (veneer and joinery boards) and chipboard (plywood and fiberboard).

Veneer plates or plywood are made of peeled veneers that intersect at right angles concerning the direction of fiber stretching or some other smaller angle (star plate). They can be made as three-layer (triplex) and multi-layer (multiplex) panels.

Particleboard is made of wood chips or other lignocellulosic raw materials (straw, corn, hemp, flax, etc.). They bond with an adhesive made of synthetic or natural resins, with the action of heat and pressure.

Fibreboards are produced by connecting wood fibers or other lignocellulosic substances by heating.

Other attractive plates are solid wood boards, wood-cement boards, light construction boards, combined boards, and wood-plastic composites.

The technology of chipboard production is more complex than the technology of plywood. Investments and capacities of production plants are higher. For that reason, you can use synthetic adhesives urea-formaldehyde (KF), phenol-formaldehyde (FF), melamine-formaldehyde (MF), polyisocyanate, and mineral binders (cement, gypsum, magnesite) for the production of wooden plates.

Depending on the type of wooden plate and the production process, other chemical components, you can use hardeners, fillers, hydrophobic agents, so-called: formaldehyde traps, fire retardants, fungicides, insecticides, plasticizers, etc.

Plate Weight Formula

To calculate the weight of a plate, you only need this information: length, density, width, and thickness. You can use this formula:

W_{p} = A_{p}\cdot T_{p}\cdot D_{p}


Wp – Plate weight
Ap – Plate area
Tp – Plate thickness
Dp – Density of material

How to Calculate Plate Weight?

When it comes to calculating the weight of a plate, you have to know the plate’s dimensions. You can also calculate the weight of a plate by measuring the depth and width of the plate. There are two ways to calculate the weight of a plate. The first is to use the density of the material. The second is to multiply the dimensions of the plate by the thickness. The weight will be different depending on the material.

To know if the material meets our needs, we need to determine the weight of the plate. If the plate is larger, it would be helpful to see the weight for both structural analysis and logistics.

How to quickly calculate the weight of the plate? You need to multiply the surface of the plate by its thickness to get the volume. When you get the required volume, multiply the volume with the density of that material, and you will get its weight. In short, we have already mentioned the formula you can use in the text above.

Plate Weight Calculator: Example

To sum up here is one more example that will best explain the application of our calculator. You need to calculate the weight of the two rectangular pieces needed to make the radiation-resistant door. You have the next information: the lead plate is 0.9 m x 2.5 m x 6.0 mm. How will you do it?

If you take into account that the density of lead is 12,350 kg / m3, the weight of one plate can be calculated as follows:

W_{p} = A_{p}\cdot T_{p}\cdot D_{p} \Rightarrow W_{p} = 0.9\cdot 2.5\cdot 0.006\cdot 12350 \Rightarrow W_{p} = 166725

We can conclude that one piece of lead plate is resistant to radiation weighing about 166.725 kg. Our example requires you to calculate two plates. What you need is to multiply the result obtained by 2. The total weight will eventually be 166.725 x 2 = 333.450 kg.

Our calculator will help you calculate the weight of the board for some other materials.

Plate Weight Calculator – Materials List

Our calculator offers many types of materials, and we will list some of them:

  • Aluminium – Aluminium is a silvery-white metal that is the most abundant metal on Earth (more than 8% of the mass of the Earth’s core). Aluminum sulfates are the most common natural form of aluminum.
  • Copper – One of the most critical metals in the industry is copper. After aluminum and iron, it is the metal that is most consumed. You can use copper in electrical engineering, telecommunication cables, electric wires, etc.
  • Bronze – Bronze is one of the earliest metals. It is made by adding copper but may also contain some additional elements. Bronze is considered an alloy of copper with certain specific properties and elements (lead, zinc, manganese, etc.).
  • Brass – Brass is an alloy of copper and zinc. Due to its hardness and good workability, it is of great historical importance. Zinc content affects the flexibility of brass. If brass contains more than 45% zinc, it cannot be processed or hot/cold.

Plate Weight Calculator Units

The Plate Weight Calculator is a unit converter that converts the weight of a plate to different units. The plate weight calculator provides users with the option to convert weight to:

  • millimeters (mm),
  • centimeters (cm),
  • meters (m),
  • inches (in),
  • feet (ft),
  • yards (yd).


How do you calculate material weight?

You can calculate the weight of the board using the formula:
  plate \; weight = plate \; area \times plate \; thickness \times material \; density

How do you calculate the weight of a round plate?

A round plate weighs more than a square plate of the same size because it has a larger surface area. To calculate the weight of a round plate, you need to multiply the weight of a square plate of the same size by the surface area of the round plate. For example, if a square plate weighs 1 pound and has a surface area of 8 square inches, a round plate with a surface area of 16 square inches will weigh 4 pounds.
