Abstract

The invention relates to a light construction wheel of steel sheet which is produced by the cold working of a flat, one-piece circular steel sheet disc formed by the welding together of a first circular disc (1) and a second annular disc (3). In the light construction wheel the first circular disc (1) for the wheel disc/dish (1*) and the second annular disc (3) for the wheel rim (3*) are made from different uncoated or coated sheets which differ in thickness and/or strength of material in accordance with the local given strength requirements of the light construction wheel.
