S355J2W
S355J2W is weather resistant steel which is intended for use in load bearing or heavy structures due to its greater tested impact strength. It is also suitable for low temperature working environments.
Like all weather resistant steels, S355J2W is self protecting – the material rusts over time due to the reaction with chemical elements in the air. This rust layer acts a protective barrier which prevents further oxidation. The steel is economical to use and is fully recyclable. As a structural steel it is can be used as easily for load bearing duties as it can for purely cosmetic purposes.
Benefits of Using S355J2W
- Excellent impact strength
- Ideal for heavy use or in low temperature
- Can be used in–situ without the need for expensive treatment or painting over time
- Popular material with architects for use in steel sculptures and modern structures due to aesthetic appeal
