Anti-skid loading surface for lorry, has corners whose side edges projected over base level of surface of board after bending, where board is made of steel sheet and corners exhibit different alignments relative to driving direction

摘要

The surface (1) has corners (2) whose side edges (5, 6) are detached from a board (4) by punching or stamping and projected over a base level (11) of a surface of the board after bending. The board is made of metal i.e. steel sheet. The corners exhibit different alignments relative to driving direction. The board is designed with ductile compound at lower side facing away from the corners, where the ductile compound is made of epoxy resin and the corners are made of hard material.
