Pile material: The pile material of DC charging pile is usually low carbon steel plate, which occupies the mainstream of the market because of its high strength, fire resistance, high temperature resistance and good heat dissipation performance. The thickness of low carbon steel plate is generally about 1.5mm, and it is processed by sheet metal tower punching, bending and welding.

Outdoor protection and heat insulation: Some DC charging piles take into account the needs of outdoor protection and heat insulation, will adopt a double-layer structure design, in which the pile structure design uses low carbon plastic steel plate to prevent the deformation of the charging pile structure.

Anti-corrosion design: Because the charging pile needs to be used in the outdoor environment for a long time, there are high requirements for the corrosion resistance of the material. After processing, the low carbon steel plate is usually sprayed with outdoor powder coating or outdoor paint to improve its corrosion resistance to ensure the service life of the charging pile.

Structural strength: In order to ensure the overall strength of the charging pile, the pile made of low carbon steel plate is usually welded with reinforcing bars or reinforcing plates.

Safety performance: Low carbon steel plate has good mechanical properties, and can pass safety tests such as falling ball impact experiments to meet the safety performance requirements of charging piles.

In summary, low carbon steel plate because of its excellent physical properties and processing properties, has been widely used in the manufacturing of DC charging pile, not only to meet the functional needs of charging pile, but also in line with the development trend of environmental protection and low carbon.
