Infrastructure & Heavy Steel Projects
Metro Station Structures, Bridge Girders, Power Plants & Toll Plazas
Engineered for Sector-Specific Structural Demands
Public infrastructure projects demand rigorous quality control, full material traceability, EN 1090-2 structural steel execution compliance, and complex heavy rigging capabilities. Yatee partners with Tier-1 EPC contractors and government authorities to fabricate and erect heavy infrastructure steelwork.
Industry Challenges & Engineered Solutions
Stringent NDT & Inspection Standards
100% radiographic and ultrasonic weld testing under third-party inspection (TPI) agencies.
Automated SAW welding, calibrated CNC drilling, and computerized trial shop assembly of complex nodes.
Complex Heavy Lifts in Urban Environments
Erecting massive steel girders over operating highways and live railway lines under tight night possession windows.
Tandem crane hoisting plans simulated in 3D CAD to ensure safe, rapid installation during rail blocks.
Severe Atmospheric & Corrosive Exposure
Structures exposed to heavy vehicle emissions, marine coastal salt air, and extreme weather cycles.
High-spec 100-micron hot-dip galvanizing and polyurethane topcoats for 50-year maintenance-free life.
Recommended Building Systems
Heavy Plate Girders
Built-up welded box girders and I-girders with plate thicknesses up to 80mm.
Tubular Arch & Space Trusses
Curved aesthetic tubular trusses for metro station canopies and airport entry gates.
High-Strength Anchor Systems
Grade 8.8 / 10.9 hot-dip galvanized anchor bolts and specialized elastomeric bearing pads.
Key Engineering Considerations & Codes
- Fatigue stress calculations for dynamic vehicular and high-speed train vibrations
- Differential thermal deflection across long-span bridge girders
- Wind vortex shedding and aerodynamic stability analysis on tall canopy canopies
