First, open-air stacking should be lowered, that is, mouth down, in order to avoid rusting in the water, and open-air stacking of profiled steel, there should be wooden mats or strips below, slightly inclined stacking surface, in order to facilitate drainage, and pay attention to the material placing straight, to prevent bending deformation.
2. Stacking height, manual operation not exceeding 1.2m, mechanical operation not exceeding 1.5m, stacking width not exceeding 2.5m. And the stacking bottom cushion is high, if the warehouse is the cement floor of Chaoyang, the cushion height is 0.1 m; if the warehouse is the cement floor, the cushion height should be 0.2-0.5 M. If it is an open-air site, the height of cement floor cushion is 0.26m; 0.3-0.26m; the height of sand and mud surface cushion is 0.5-0.7m.
3. The principle of stacking requires that the materials of different varieties should be stacked separately to prevent confusion and mutual corrosion under the condition of stable stacking. And it is forbidden to store articles which have corrosive effect on steel near the stack.
4. The bottom of the stack should be padded high, firm and flat to prevent dampness or deformation of the material. There should be a certain passageway between the stack and the stack. The inspection path is generally 0.5m. The access passageway depends on the size of the material and the transport machinery, generally 1.5-20m.
