A method for producing a metal composite material with an embedded functional structure, in which a build-up of layers comprising a number of layers that are arranged one on top of the other in the vertical direction is produced and pressed, may involve producing the build-up of layers by providing a lower layer comprising a metal substrate, arranging at least in certain portions over the lower layer in a vertical direction an intermediate layer that is in contact with the lower layer, and arranging one or more functional structures respectively in a portion of the build-up of layers. To reduce the risk of increased degradation, before the pressing, the build-up of layers may have the same thickness in the respective portion with the functional structure as in the remaining build-up of layers. Further, a metal composite material with an embedded functional structure may be produced by such a method.

A method for producing a flat steel product with high reflectivity, in which at least one surface has an arithmetic mean roughness Ra of less than 0.03 &#x3bc;m includes providing a flat steel product, at least one surface of which has an arithmetic mean roughness Ra of less than 2.5 &#x3bc;m. The flat steel product is cold rolled in a plurality of rolling passes. Also a flat steel product with high reflectivity in the finished re-rolled state on at least one of its surface has a low arithmetic mean roughness, a high gloss, and a high directed reflection. A solar concentrator is produced from such a flat steel product.

The invention relates to a support device for a curved mirror having support elements and a curved mirror. The objective of providing a support device for a curved mirror which is constructed in a particularly simple manner and which enables particularly low production costs is achieved by a support device in that the support device has at least one bent metal carrier profile-member, the bent carrier profile-member having in the longitudinal direction an at least similar curvature to the curved mirror and being substantially mirror-symmetrical in the longitudinal direction.
