Where this plate fits
For exposed steelwork, keep the W suffix on drawings and cut lists. S355J2 and S355J2W point to different product standards. When the parts are intended to remain unpainted, check drainage and how runoff will reach adjoining surfaces.
Before requesting a quote
Send the plate schedule, surface specification and certificate requirements. The historical chemistry below helps distinguish this designation. Use the ordered EN edition and certificate for acceptance.
Frequently asked questions
Can S355J2W be specified as S355J2WP?
These are separate designations in EN 10025-5. Match the drawing and the material certificate to the approved grade.
