Steel Knowledge · Material grades
S355NLH belongs to a structural hollow-section material family with a distinct delivery and impact-toughness designation.
N, L and H form part of the full grade identity. The required testing and delivery requirements must be confirmed from the applicable edition of the product standard.
State S355NLH in full, with the product standard, section size and required test documentation.
Similar S355 grades are not automatically equivalent; toughness and delivery conditions may differ.
Related catalogue context is not a certification statement. Validate process, edition, product scope and the supplier's actual offer.
These are references from the governed public source record, not a statement of equivalence or current certification.
