Abstract
A metal structure component is provided with a protective coating including three layers. A first layer on the surface of the metal structural component is a bond improving metallic base layer on which an intermediate heat insulating oxidic layer is applied, followed by a titanium fire inhibiting metallic cover layer. Due to this arrangement of three layers, it is possible for the advantageous characteristics of the individual layers to cooperate to provide a good bonding and heat insulating protection of the intermediate layer in combination with the titanium fire inhibiting protection of the outer layer, whereby the structural component achieves a prolonged operational life without a substantial weight increase as compared to conventional protection layers provided only for heat insulation purposes. This layer structure also minimizes any adverse influence on the structural strength of the metal structural component.
