Engineering Overview & Fabrication Workflow
Structural Design & Statics
Model FD-LND-087 is dimensioned and engineered in STAAD.Pro and ETABS adhering strictly to ASTM D4716 Sub-Drainage / USGA Sand Cap / Hunter WaterSense. 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 Cast Iron body + SS304 shaft 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.
