Abstract: A holding element made of a sheet metal for at least one solar element, more particularly a solar module and/or solar collector, with a base that forms a support surface for the holding element, with two supports for the solar element that protrude up from the base at different heights, and with connecting elements, which are provided on ends of the holding element is disclosed, which has at least one, more particularly hole-shaped, opening and at least one tab, which tab is shaped for being inserted into such an opening. In order to be able to easily install a highly rugged holding element, it is proposed for at least one opening and at least one tab to be respectively provided next to each other on each of the ends, wherein the sheet metal is a metallically coated, more particularly hot-dip coated, sheet steel.

Abstract: The method relates to a press-hardened component with a tensile strength Rm>1600 MPa, in particular >1800 MPa, and especially >2000 MPa, wherein the component is manufactured from a steel material, wherein the steel material is a boron-manganese steel, which has a carbon content >0.30 mass %, wherein the steel material is hot rolled or hot rolled and cold rolled to a strip with a thickness of 0.5 to 3 mm, wherein the strip has a thin coating of zinc or a zinc-based alloy and a coating weight of <50 g/m2 on each strip side of the steel strip.

Abstract: The invention relates to a method for conditioning the surfaces of heat-treated galvanized steel sheets or alloy-galvanized sheet steel components, wherein either a steel sheet is heated in at least some regions for the purpose of austenitization and then is formed into a sheet steel component and cooled at a speed above the critical cooling rate, or a steel sheet is first formed into a sheet steel component and then heated in at least some regions for the purpose of austenitization and after the austenitization in at least some regions, the sheet steel component is cooled at a speed above the critical cooling rate. In both cases, the surface of the sheet steel component then undergoes an airless blast cleaning, characterized in that the airless blast cleaning is carried out with an Almen intensity of between 0.05 mm N and 0.20 mm N.

Abstract: The invention relates to a method for heating a sheet steel blank or preformed component with a zinc or zinc alloy coating, wherein the sheet steel component or blank is guided or positioned in a furnace and heated to a temperature above the austenitizing temperature, the sheet steel component or blank at least temporarily rests on a plurality of support surfaces on at least one carrier in which, on the support surfaces for the sheet steel blank or component, either a) the support surfaces are each a maximum of 200 mm2 in size, and/or b) the support surfaces consist of a porous and/or rough oxide ceramic or carbide ceramic or high-temperature resistant cast steel so that oxygen access to the surface of the steel sheet blank or component is ensured even in the region of the support surface An apparatus for carrying out the method is also provided.
