How do outdoor fabric installations handle thermal expansion in metal supports?
Outdoor fabric installations are designed to accommodate thermal expansion in metal supports through several key strategies. First, flexible materials like PTFE-coated fiberglass or PVC fabrics are used, as they can expand and contract without losing structural integrity. Metal supports are often engineered with expansion joints or sliding connections to allow movement caused by temperature changes. Proper tensioning systems ensure the fabric remains taut while accommodating shifts. Additionally, structural designs may incorporate curved or segmented supports to distribute stress evenly. Regular maintenance checks also help identify and address any issues caused by thermal expansion, ensuring long-term stability and performance.
