Corrosion and Abrasion Measures  Galvanized in accordance with ASTM-123  Design corrosion rates conform with AASHTO & FHWA-RD-89- 186 metal loss rates  Minimal abrasion in 50/6 soil (WSDOT) 4Fe+3O 2 +4H 2 +8H + = 2(Fe 2 O 3 H 2 O)+2OH 2 O+8H +

7. UAS Universal Anchoring Solutions Slide 2.1 Concrete vs. Helipost The Problems with Concrete: Complicated - Labor intensive and equipment heavy, with multiple crews necessary to complete the installation process. Expensive – Inefficiencies due to the common logistical challenges, materials, and equipment used for concrete installation add both time and money to the project costs Slow – The curing period required before concrete piers and anchors are ready to accept the above-ground unit adds days or weeks to project schedules.
