Abstract

The metal grill (10) is made from a combination of round (16) and flat bars (12). The flat bars have holes (22), to suit the dia. of the round bars equally spaced along their length. The flat bars are arranged to be parallel to each other with the round bars passing through the holes so that a grid is formed. The grid is then placed in a press which flattens the round bars in the spaces between the flat bars with the newly formed flat surfaces lying parallel to the plane of the grid. The deformed bars are then rotated through 90 deg. so that the flat surfaces are perpendicular to the plane of the grid. A final operation forms an indentation (46) in the original flat bars to ensure that they grip the deformed bars.
