WORKSHOP PACKAGING

Packaging and loading:

Packaging: According to customers' needs, use wrapping paper. If the transportation period exceeds 10 days or encounters special climate, we will use waterproof packaging and add plastic film to prevent moisture, water and rust.

Loading: We use the wooden pallet,triangular wood to fix the coil,and the steel wire rope to hold on the both side. That can prevent from the crush injury effectively.
