Engineering Overview & Fabrication Workflow
Structural Design & Statics
Model FD-PVD-144 is dimensioned and engineered in STAAD.Pro and ETABS adhering strictly to ASTM B117 (1200hr Salt Spray) / ISO 14577 / ASTM D3363 10H Hardness. Connection plates feature moment-resistant haunch joints with high-strength Grade 8.8 / 10.9 structural bolts. Designed to withstand regional seismic accelerations and intense 140 km/h wind gusts without exceeding allowable deflection limits of L/240.
Material Science & Quality Control
Fabricated using verified mill-certified SS304 1.5mm Mirror PVD steel billets. Components undergo 100% automated submerged arc welding (SAW) and ultrasonic non-destructive testing (NDT) to eliminate weld laminations. Corrosion protection includes SA 2.5 shot-blasting followed by high-build epoxy or cathodic arc titanium PVD coatings delivering 30+ year service life.
