Serviceability Deflection Limits (SLS): Strict deflection limits from L/300 to L/500 preventing cracks in architectural cladding and interior drywalls.

Structural Mechanics, Load Paths & Finite Element Modeling

How vertical gravity, lateral wind, and seismic forces are dissipated through our engineered framing.

1. Vertical Gravity Load Transfer

Engineered structural steel buildings where 100% of field connections are achieved using high-strength structural bolting assemblies (Grade 8.8 and 10.9 per EN 14399 and EN 15048). Precision CNC-drilled connection plates (tolerance < 0.5mm matching EN 1090-2 Class 1 hole clearance) transfer axial, shear, and bending forces with zero slip.

2. Lateral Wind & Seismic Ductility

Preloaded (friction-grip) and non-preloaded bolt assemblies provide immediate structural rigidity under seismic and wind reversals, eliminating on-site hot work permits, fire hazards, and weld inspection delays.

3. Thermal Break & Moisture Control

Shop-applied protective coatings (intumescent fire paints and epoxy primers) remain 100% intact across the entire frame because no field burning or welding damages the paint system on site.

European Eurocodes & Global Standards Compliance

Fully verified structural calculations meeting European, British, and international building codes.
