ArcelorMittal Europe offers products with top fire reaction performances:

• As bare material, steel is classified A1, which is the best performing level.
• Granite® organic coated steels are also A1 Euro class.
• Our sandwich panel product range goes up to A2-s1-d0 classification.

Therefore, ArcelorMittal Europe’s product range is able to satisfy the most demanding national regulations concerning fire reaction performance.

Fire reaction indicates the way a material behaves as a combustible.

Construction products’ reaction to fire is determined through Euroclasses. The Euroclasses were introduced following a resolution by the Commission (2000/147/EEC) on 8 February 2000 to create a common platform for the comparison of the fire properties of construction materials.

Fire testing of products is conducted in accordance with harmonised testing methods. As defined by a series of European standards, this includes several tests and related performances:

• Classification for combustibility. Class A1 is non-combustible and the requirement level cannot be combined with any additional class mentioned below.
• Additional classification for smoke development, identified by the symbol s.
• Additional classification for burning droplets, identified by the symbol d.
