Abstract
A slotted grate (3) is disclosed which is formed of a sheet metal strip with slot (15) therein. Reinforcement of the grate (3) is achieved by inserting a sheet metal arch support (30) between two adjacent slots (15). The arch support (30) is formed of a piece of sheet metal bent into a U-shape with shoulders (35, 36) of its end sections (31) being spaced further apart than the shoulders (37, 38) of its midsection (32). A process is disclosed wherein the slotted grate (3) is constructed by first placing arch supports (30) between the desired slots (15) and then double bending the edge sections of the sheet material forming the grate (3) to form two U-shaped side channels with the shoulders (35, 36) of arch support (30) locked securely therein.
