Packing requirement
A, the materials used must have sufficient strength to ensure that the goods are not scattered;
B. Requirements for the number of strapping channels: at least 2 strapping channels of components less than 5m in length; At least 3 parts of 5m to 10m; At least 4 parts of more than 10m (in this principle, if the weight of the member is large, can be appropriate to add the number of channels);
C. Components should be placed reasonably in the stacking process. Interlining (leather, packaging blanket, etc.) can be added appropriately between components according to the situation to ensure that components cannot slide each other;
D. If screw is used for fixing, measures should be taken to prevent falling off during transportation, such as spot welding of nuts or destroying exposed screw rods;
E. Lifting lugs can be appropriately added to the packaging according to the lifting habit to facilitate loading, unloading and transportation, but the lifting lugs should be solidly welded and reasonably designed;
F. When packing components, try to make the section of the packaging parts square to increase its fixity. As far as possible, do not pile only one layer to form a long rectangle.
4.1.3 Standard packaging drawings
4.2 Frame Packaging
The use of a number of Angle iron, channel steel, I-steel (steel plate cutting edge iron) and other materials connected to bear vertical and horizontal load of the space structure.
4.2.1 Application Scope
The size, weight and shape of a single component are not suitable for either naked or bundled components.
4.2.2 Packaging Requirements
A, the material must use solid channel steel, Angle iron, I-steel or steel plate cutting edge iron, resolutely do not use wooden frame;
B, the member must be all framed in the frame, no edges and corners are missing outside the frame;
C, the framework of the components can be fixed according to the situation using wire and other materials, there shall be no potential factors of channeling, collision;
D. In principle, there should be padding between the components to protect the components themselves from damage;
E. Components placed in the frame should be filled with the volume of the frame as far as possible, at least not less than 90%;
F. Reasonably design the lifting lugs and center points according to the lifting habits. The welding requirements of the lifting lugs should be firm, and the lifting points and center points should be marked accurately.
4.2.3 Standard packaging drawings
in the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.
