<p>The grating or mat is made up from parallel load bearing bars and interconnecting spacers, connectable by plugging undercut profile pieces together. The bars (1) have an upright shape, with their width (3) a fraction of the height(2). On each vertical side face are undercut profile pieces (7). Spacers (8) are relatively flat in cross-section and low (13) compared with width (12) with complementary undercut sections (9) on their side faces. This permits length adjustments.</p> |
