The present invention relates to aluminum plated steel sheet which does not require coating after plating and is high in production flexibility enabling application of conventional production processes as they are or exhibits excellent corrosion resistance to flex fuels and further is excellent in appearance and to fuel tanks characterized by being produced using the steel sheet. The Si, Mg, Ca, and Ti ingredients in the aluminum plating layer are defined and the cooling method after hot dip aluminum coating is controlled to make Mg.sub.2Si particles with a long axis of 10 μm or less and an aspect ratio of 1 to 3 finely disperse in the plating layer. Due to the Mg.sub.2Si particles, it is possible to give an excellent corrosion resistance to flex fuels and suppress the deterioration in appearance due to MgO.

A coating process includes the successive steps of preparing the zone to be treated. At least one coat of a primer is applied to the prepared zone to obtain a thickness ranging from 100 to 450 micrometers. The zone to be treated is then reconditioned and a least one top coat is applied to obtain a thickness ranging from 100 to 450 micrometers.

The invention comprises a relatively lightweight cementitious-based material panel. The cementitious-based material panel comprises a foam insulating panel having a first surface and a second surface; a first structural layer of cementitious-based material formed on the first surface of the foam insulating panel and affixed thereto; and a second non-structural layer of cementitious-based material formed on the second surface of the foam insulating panel and affixed thereto. The second non-structural layer of cementitious-based material is substantially thinner than the first structural layer of concrete. The second non-structural layer of cementitious-based material is preferably formed from polymer modified concrete, plaster or mortar. A method of making the cementitious-based material panel is also disclosed.

A flat steel product for hot forming may be produced from a steel substrate that includes a steel comprising 0.1-3% by weight Mn and up to 0.01% by weight B, along with a protective coating that is applied to the steel substrate. The protective coating may be based on Al and may contain up to 20% by weight of other alloy elements. Also disclosed are methods for producing such flat steel products, steel components, and methods for producing steel components. Absorption of hydrogen is minimized during heating necessary for hot forming. This is achieved at least in part through an alloy constituent of 0.1-0.5% by weight of at least one alkaline earth or transition metal in the protective coating, wherein an oxide of the alkaline earth or transition metal is formed on an outer surface of the protective coating during hot forming of the flat steel product.
