Assembly Instructions

Maintenance and Care
This heart-shaped arch is constructed from high-quality iron with a white coating, designed for durability and corrosion resistance. To ensure longevity, store the arch in a dry place when not in use. Clean the metal frame with a soft, damp cloth. Avoid using abrasive cleaners that could damage the coating. The arch is reusable for multiple events.
Troubleshooting
- Arch Instability: Ensure all connecting pipes are fully inserted and fixing nuts are tightened. For outdoor use, always fill and place the water bags on the base to provide sufficient weight. If water bags are insufficient, consider using sandbags.
