The package is a cylinder made of polyethylene or polyvinyl chloride material. The two-end structure is a double-layer structure. The double-layer structure is provided with a gap structure arranged in intervals, and a string is twined in the double-layer structure. There is a two-wing structure in the middle of the two ends and a tying rope in each of the two wing structures. The utility model has the advantages of good material selection, and is made of polyethylene or polyvinyl chloride material, so that the cost of the product is greatly reduced; due to the spigot structure at both ends and the two-wing structure, the steel is packed solidly, during transportation or hoisting process Not easily scattered, not easily damaged, not easily corroded by rain. Sovereign item 1, steel coil packaging material, characterized in that: the package is a cylinder made of polyethylene or polyvinyl chloride material, the two-end structure is a double-layer structure, double structure is arranged on the interval The nick structure has a tether string in a double layer structure; a two-wing structure is arranged in the middle of both ends, and a tying rope is provided on each of the two wing structures.
Because Single Chair is mainly used for earthquake prone areas in the school, our country can not use high-end materials based on the guarantee of high strength and lightweight improvement more difficult; it should be to structure aspect, like SINGLE CHAIR of roller added, do not need to try to choose the structure of high strength, lightweight materials will be parts made of hollow structure. The thermal conductivity of steel material is too strong, and will affect the use, so each desk can be attached to a desk pad, use will be more convenient and comfortable; the hardness of steel is too high, no bump may cause some damage to students, but also through the angular angle can be installed in some soft material the edge of the site, such as natural rubber, thermoplastic elastomer TPR, nuts should be added at both ends of the rubber sleeve.
