How should square tubes be stored?

Square tubes are made of steel. If they are exposed to rain, they will definitely rust. Therefore, they should not be exposed to rain when stored.
1. If you need to store square tubes for a long time, you should use opaque covers to protect them from the beginning of storage to prevent rust on the square tubes and aging and warping of the anti-corrosion layer.
2. The covers should be strong and durable to prevent long-term sun and rain from rotting and leaking.
3. When covering the square tubes, the surface of the steel tubes should be ventilated to prevent water vapor from evaporating and gathering on the surface.

4. When storing square tubes, there should be supports and a certain distance from the ground to ensure ventilation of the steel tubes.

5. After the square tubes are stacked and stored, the tube end protectors should be removed to prevent moisture from gathering on the contact surface between the tube end protectors and the steel tubes and making it difficult to volatilize.
6. When storing square tubes, attention should be paid to the number of layers of steel tubes to avoid excessive layers causing local stress on the tube ends, which will cause radial plastic deformation of the steel tubes and damage the anti-corrosion layer.
7. When storing square tubes, avoid contact with pollutants such as oil and copper.
8. Formulate institutional documents for long-term storage of square tubes and implement them in accordance with the system.
