One of the best-selling industrial and construction steel sections is steel sheets, which are offered to the market in various thicknesses.
Comparison of steel sheet and plate
To accurately differentiate between steel sheet and steel plate, we need to look for a basis. Because the two are similar in terms of length and width as well as surface finish, and it is not possible to distinguish them based on such parameters. What is important for making this comparison is the thickness .
Based on thickness, types of flat sections include the following :
- Foil
- Sheet
- Strap
- Tape
- Page
But what is the thickness range to determine whether a section is a sheet, plate, or foil? To clarify this issue, we will first define each of the above items, and thus, the difference between sheet, plate, and foil will also be determined .
What is foil?
Foil or gold leaf is a very thin sheet that is rolled from a slab and its thickness is usually less than 0.1 to 0.2 mm. Although metal foils can be made from any type of metal, the most common types of foil available on the market are aluminum foil and gold leaf. Although it was said that the thickness of the foil reaches 0.2 mm at most, aluminum foils are also available in very low thicknesses of about 0.02 mm .
What is steel sheet?
Sheets are the most well-known sections in the flat product category, available in the market in forms such as black sheet, galvanized sheet, various types of oiled sheet , colored sheet, acid-washed sheet, grooved sheet, etc.
But just as a thickness range was defined for foil or sheet metal, the same is true for sheet metal. Any type of flat section that is the result of slab rolling and has a thickness between 0.2 and 6 mm is called sheet metal. Now, if the sheet in question is made of steel, it is called steel sheet metal. The most common sheets available on the market include steel sheet metal, aluminum sheet metal, stainless steel sheet metal, and their derivatives .
What is a steel belt?
Another member of the flat product family is steel strip. Strip has a similar thickness range to sheet but different width dimensions. In other words, steel strip is defined as a rolled product with a thickness of less than 6 mm and a width between 20 and 60 mm .
What is steel tape?
Steel strip is very similar to steel belt, the only difference being the width. In other words, steel strip has a similar thickness range to steel sheet and belt. Steel strip is defined as a flat, rolled section with a thickness of less than 6 mm and a width of less than 20 mm .
What is steel plate?
Steel plate, which is often confused with sheet, is a rolled slab product with a thickness of more than 6 mm. Therefore, flat sections that are more than 6 mm thick in the market are the same plate or plate that is mistakenly called sheet. Since steel plates have a high thickness, they are often used in projects where strength and durability are more important than lightness and weight savings .
Difference between steel sheet and plate
As mentioned in the definitions of sheet and plate, the most important difference between steel sheet and plate is the difference in their thickness or size. Steel sheets have a thickness of less than 6 mm, and steel plates have a thickness of more than 6 mm .
As the thickness of a piece increases, its weight increases proportionally. Therefore, steel plate generally weighs more than steel sheet. To view the sheet thickness table Click steel .
This difference in size and weight allows the thinner sheets to be used in applications where high strength and light weight are key factors. In contrast, steel plate, due to its much higher strength resulting from its thicker cross-section, can be used in applications where weight is not as important .
Meanwhile, as the thickness and size increase, the price of the product also increases. Therefore, steel plates have a higher price than steel sheets .
Conclusion
It is common in the market to call all flat sections other than foils as sheets. However, there is a wide variety of flat sections and they are divided into various categories such as foil, strip, tape, sheet and plate. What distinguishes steel sheet from plate is the size or thickness .
Thicknesses between 0.2 and 6 mm are called sheets, and thicknesses over 6 mm are called plates. Foil also has a thickness of less than 0.2 mm. Steel belts and strips also have thicknesses of less than 6 mm, and what distinguishes them from each other is their width .
