Abstract
The invention discloses a steel grating and flat steel for the steel grating. The steel grating comprises a plurality of flat steel and a plurality of twisted square steel, and is formed by press welding of the twisted square steel and the flat steel after the twisted square steel is transversely placed on the flat steel, wherein the flat steel is evenly distributed according to preset intervals. Each piece of flat steel sequentially comprises an upper end (1), a waist (2) and a lower end (3) from top to bottom in the height direction. The upper ends (1) and the lower ends (3) are thicker than the waists (3). The lower ends (3) are longer than the upper ends (1). The lower ends (3) are thinner than the upper ends (1). The thickness ratios of the lower ends (3) to the upper ends (1) range from 0.65 to 0.85. The waists are thinnest, and the lower ends are thicker than the upper ends, so that the structure can meet pressure-bearing requirements of the flat steel in the steel grating; the thickness of the flat steel is greatly reduced, so that consumption and cost of the flat steel are reduced.
