ABSTRACT:
A metallic transporting appliance, such as a flat pallet, a skid, or a box pallet, is designed so that a thin metal plate is used entirely for the pallet and skid and for the side wall of the box pallet. The thin metal plate is subjected to burring so as to have sufficient durability, thereby contributing to the reduction of the amount of wood for conventional wooden pallets in order to preserve natural resources. The metallic transporting appliance includes a main plate made from a thin metal plate having plural pairs of bores each formed at a predetermined interval therebetween in a flat surface thereof, with a slit formed between each pair of bores to couple the bore pair. The main plate has a plurality of elongated hole portions, each having a bottom hole with a flange provided by burring those portions where the bore pairs are coupled with the associated slits. This main plate is also adapted for the deck board of a skid. Lengthwise extending portions of the main plate are bent downwardly and then bent inwardly toward each other with a predetermined thickness, so that both end portions are joined at a center portion. The flanges of the elongated hole portions are welded to the extending portion by spot welding. This main plate is adapted for the deck board of a flat pallet or the side plate of a box pallet.
