Transporting metal sculptures safely requires careful selection of protective materials to prevent scratches, dents, and other damage. Here are the best materials to ensure your artwork arrives intact:

1. Bubble Wrap: Ideal for cushioning, bubble wrap provides a soft barrier against impacts. Wrap the sculpture tightly, focusing on delicate edges and protruding parts.

2. Foam Padding: Custom-cut foam sheets or blocks offer superior protection for irregular shapes, absorbing shocks during transit.

3. Acid-Free Tissue Paper: For highly polished or delicate surfaces, acid-free tissue paper prevents scratches and chemical reactions.

4. Corrugated Cardboard: Use sturdy cardboard to create a rigid outer layer, shielding the sculpture from direct pressure.

5. Stretch Film: Water-resistant and clingy, stretch film secures loose materials and adds an extra layer of protection.

For added safety, place the wrapped sculpture in a wooden crate with foam inserts. Always label the package as fragile and consider climate-controlled shipping for sensitive pieces. By using these materials, you can ensure your metal sculpture remains pristine during transit.
