What are the best methods to prevent thermal expansion gaps in metal ottoman joints?

Thermal expansion gaps in metal ottoman joints can lead to structural instability and aesthetic issues over time. To prevent these gaps, consider the following methods:

1. Use Expansion Joints: Incorporate designed gaps that allow for natural metal expansion and contraction without causing stress.

2. Choose the Right Material: Opt for metals with lower thermal expansion coefficients, such as stainless steel or aluminum alloys.

3. Proper Fastening Techniques: Use flexible fasteners or slotted holes to accommodate movement while maintaining joint integrity.

4. Apply Thermal Barriers: Coat joints with heat-resistant materials to minimize temperature fluctuations.

5. Regular Maintenance: Inspect and tighten joints periodically to address minor shifts before they become problematic.

By implementing these strategies, you can ensure your metal ottoman remains stable and visually appealing despite temperature changes.
