THE EXPLANATION OF THE MARKS ABOUT THE MAIN PARTS OF DRAWING 15 10: palette 20: upper frame 21, 31, 41: connection hole 30 lower frame 32 fixing groove 20 40 supporting leg 50 connection bolt 60 nut TECHNICAL FIELD AND BACKGROUND ART This invention is concerned with the palette which is used for loading goods in industrial field, especially steel pallet which is light, durable, and interchangeable in maintenance of its parts. Generally, the palette is used for loading the goods and for moving the goods in the industrial area. So, the palette is made in one body system by wood and plastic. The above mentioned old type palette has some problems as follows: heavy weight to use, inefficient durable strength, and difficulty in 0 changing parts. In addition, the supplying cost of wooden palette too high because of wood' s expensive price. The connection parts, such as nail, chock and so on, are prominent on the palette , so they damage the loading goods of the palette 5 DISCLOSURE OF INVENTION This invention is for eliminating the problems of old type palette and this invention provide us with light, durable, interchangeable, convenient steel palette BEST MODE FOR CARRYING OUT THE 0 INVENTION Fig 1 is the disassembled four side view drawing which shows the production process of palette (10) suggested by this invention. Fig 2 is the general view drawing which shows recommendable application example of palette (10) suggested by this invention. 5 Fig2 shows also that this invention is composed by as follows: upper frame(20) which is formed as prominence and depression by bended plate metallic material, lower frame(30) which is bended as rectangular hexahedron and latticed arranged under the upper frame(20), supporting le (40) which is formed as prominence and depression by bended plate metallic material, connection bolt(50) and nut(60) for connecting the above upper frame(20), lower frame(30) and supporting leg(40). The above upper frame(20) ' s formed depression portion has at least one or more connection holes(21 ), the lower frame(30) has a lot of connection holes(31 ), and the prominence portion of supporting legs(40) have at least one or more connection holes(41 ). Fig 3 is the sectional drawing which shows the connection condition of palette in accordance with this invention. The drawing shows that the lower frame(30) and upper frame(20) is latticed arranged and they connect with supporting leg(40) under some point where the upper frame(20) come across the lower frame(30). At the same time, the connection bolts(50) penetrate every connection hole(21, 31, 41) and tighten nut(60) to connect, while the connection holes(21, 31) of the upper frame (30) and lower frame (30) is united to the connection hole(41 ) of supporting leg(40). On the other hand, the application example shows that the lower frame(30) was arranged with three line and the supporting leg(40) was connected in the across point of lower frame(30) and upper frame(20). But the quantity of lower frame(30) can be changeable, if necessary. Also the position of supporting leg (40) which connect with lower frame (30) can be changed. INDUSTRIAL APPLICABILITY This invention has merits as follows: The palette (10) is too light to use conveniently, because it's material is plate metal. The parts are easily interchangeable, and the maintenance is very easy. Because the upper frame(20), lower frame(30), supporting leg(40), and the other parts are connected by connection bolt(50) and nut(60). In comparison with old type palette , it also has merits on low supplying cost and economical durability.

Claims: CLAIMS 1. Upper frame(20) which is bended plate metallic material with prominence and depression and the depression parts have at least one or more connection holes(21 ). Lower frame (30) which has a lot of connection holes( 31 ) and latticed arranged as rectangular hexahedron under the upper frame(20). Supporting leg (40) which is formed as prominence and depression by bended plate metallic material and it has connection holes(41 ) on its prominent port with connection under some point where the upper frame(20) come across the lower frame(30). Steel palette includes upper frame(20 ) and lower frame(30) with connection holes(21, 31), connection bolt(50) penetrating supporting le (40) and connection hole(41), and nut (60) for tightening.
