Metal sheet formats
The large variety of sheet and plate formats and properties are found today in steel. A metal sheet or plate is basically relatively thin but has a large area. It is because of this low thickness that it is easy to work cold, i.e. at room temperature, by bending, folding or rolling. These metal plates are traded in different sheet formats, as sheet material or they are wound on a roll (coil). If the material is purchased as a coil, an uncoiling machine is needed to further work the material.
The starting material for sheet and plate production is slabs (metal blocks). These are driven between rolls with increasingly closer distance between the rolls until the required thickness is achieved. Larger thicknesses are produced by hot rolling (working the metal in red-hot condition) and smaller thicknesses are produced by cold rolling. After rolling the material is cut to the required sheet or plate format.
Metal sheet and plate formats and sizes
Metal sheets and plates are mainly divided into 3 sizes/formats. These include:
- Small format
2.00 m x 1.00 m
- Medium format
2.50 m x 1.25 m
- Large format
3.00 m x 1.50 m
Notwithstanding this, other large format sheets can also be used. Oversize (XL) formats are, for example, 6,000 x 2,000 mm or 12,000 x 3,000 mm and even 16,000 x 2,000 mm. The largest possible sheet or plate format is approx. 20,000 x 4,000 mm. This large format steel is needed mainly in shipbuilding or on drilling platforms.
