Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

| Résumé : |
Coating manufacturers have long contended that the extended maintenance intervals made possible by the use of high-performance, highly durable coating systems, far outweigh their initial contribution to the eco-footprint of a structure when the benefit that accrues from the use of coatings is taken into account over the whole of its life. The authors discuss a study to test this contention, quantifying the effect of coating systems of varying durability (and hence varying maintenance requirements) on the environmental impact of a steel bridge over the course of its functional life. |
