In <strong>lightweight structures<\/strong>, the perimeter detailing dictates how dynamic environmental loads (aerodynamic flutter, snow accumulation) are transferred from the flexible membrane to the rigid <strong>space frame<\/strong>.<\/p>\r\n\r\n    <ul>\r\n        <li><strong>Catenary Cable Tensioning:<\/strong> Edge cables must be manufactured from 316 or 316L stainless steel wire rope. To prevent membrane fatigue, cables are systematically pre-tensioned to 15% \u2013 20% of their theoretical breaking load during installation.<\/li>\r\n        <li><strong>Anti-Corrosive Coatings:<\/strong> All structural steel connection nodes, clevises, and base clamping plates must undergo rigorous surface preparation (Sa 2.5) followed by a C5 marine-grade coating system. This typically consists of an epoxy zinc-rich primer and a UV-stable aliphatic polyurethane topcoat, ensuring zero rust bleeding onto the pristine membrane.<\/li>\r\n        <li><strong>Abrasion Isolation:<\/strong> Where the fabric meets the rigid support structure, extruded aluminum clamping tracks or heavy-duty Keder edges must utilize EPDM (Ethylene Propylene Diene Monomer) rubber gaskets. This isolates the membrane from the steel, eliminating friction-induced micro-tears under cyclic wind loading.<\/li>\r\n    <\/ul>\r\n\r\n    <div class=\"cta-wrapper\">\r\n        <a
