Transportation and storge for clad plates
Aug 08, 2018

The corrosion resistance of stainless steel is due to the formation of a passivation film on the surface, so care should be taken to maintain the passivation film intact. Pay attention to the following aspects during the transportation and storage of stainless steel composite panels:


- Pay attention to moisture, dust, oil, lubricating oil, etc. during storage to avoid surface rust or poor soldering corrosion resistance.

- When intrusion of moisture between the film and the steel substrate, the corrosion rate is faster than when the film is not applied.

- Store in a clean, dry and ventilated place, keep the original packaging state, the filmed stainless steel should avoid direct sunlight, the film should be periodically checked, if the film is deteriorated (film life of 6 months) should be replaced immediately, If the packaging material is soaked when padding paper, remove the pad immediately to prevent surface corrosion.


- In order to avoid surface scratching during transportation, rubber or sleepers should be used. Stainless steel protection special materials should be used as much as possible. In order to avoid surface contamination caused by fingerprints, gloves should be worn during operation.


-Special spreaders are recommended for stainless steel composite panels and composite rolls when lifting. It is easy to slip when using a wire rope, and it is easy to crush and scratch the surface of the stainless steel layer, causing defects.


-When the stainless steel composite coil is stacked, it is recommended to lay protective materials such as rubber sheets underneath to avoid crushing the surface of the steel sheet. The studs must be used when stacking stainless steel clad plates. The studs should have the same height, and the distance between them should be equal and appropriate, so that the weight of the steel plates can be evenly distributed to avoid the shape problem.


- The composite panel is recommended to be indoors and should be covered with tarpaulin if stored outdoors. When storing indoors, you should pay attention to monitoring the temperature and humidity in the room to avoid "condensation" caused by sudden changes in temperature and humidity.
