Galvanizing:

We use hot dip galvanization treatment to protect the tower. The towers with zinc layer coating are more difficult to be damaged. There is a strong resistance to corrosion.

Packing frame shall be used to bundle the steel structure to avoid damage to the galvanization, and each bundle has a label showing the packing list.
