Abstract
The sheet metal has raised sections at one side which are made by drawing the material. The raised sections are in the shape of rectangles with a concave top surface. The small sides of the rectangle are raised sharply from the sheet material while the long edges of the rectangle are slightly curved, so that the centre of the surface is approx. level with the surface of the sheet material. The raised sections are made in rows on the surface of the sheet and are so placed that the diagonals of the rectangles are approx. in line. The sections can also be positioned with the concave top surfaces lying at right angles to one another.
