Floor plates are embossed steels with a chequered or teardrop pattern on the surface.
The steel used is generally structural steel according to the EN 10025 standard.


For floor plates with a chequered pattern, ArcelorMittal has a specific grade, S235DIAMOND, which guarantees only the chemical compositions required for S235JR according to EN 10025-2:2004.


For floor plates with a teardrop pattern, ArcelorMittal also offers other grades, including:


Different patterns are available:


EN 10363 R chequered pattern

The height of the checkerboard pattern is between 1 and 2 mm.



EN 10363 T teardrop pattern


L: approximately 30 mm

e: approximately 10 mm
h: 1 to 2 mm except for core thickness of less than 2.5 mm for which h may vary between 0.5 and 2 mm.




ASTM or EN 10363 A teardrop pattern


a = 3.6 mm

b = 9 mm (- 0 + 1.7)

c = 22.7 mm

d = 23.3 mm (- 0 + 3.8)

e = 1 to 2 mm (depending on core thickness)


The embossed relief gives the floor plate anti-slip properties, irrespective of whether the environment is dry, greasy or damp. Moreover, it is an extremely hardwearing surface that provides excellent resistance to wear due to abrasion, impact and the passage of vehicles, and is also popular with designers for decorative use.

On request, ArcelorMittal's embossed floor plate is also available in Indaten® 355A, which is a weathering grade with good atmospheric corrosion resistance (see data sheet A34).


Floor plates are mainly used for:

Recommendations for use

Floor plate may be processed in the same way as smooth sheet of the same quality (bending, forming, welding etc).
