Profile Geometries & Raw Metallurgy

Profile Geometries & Section Dimensions: Heavy-gauge door jamb and header sub-framing with integrated track mounting brackets
Structural Steel Grade & Yield Strength: S355 Structural Steel Door Trusses + Galvanized Jamb Profiles
Corrosion Protection & Surface Treatment: Hot-dip continuous galvanizing Z275/Z350 (EN 10346) or batch galvanizing per ISO 1461 (min 85 µm) & SA 2.5 shot-blasting with 2-pack epoxy primer for C1 to C5-M corrosivity.
Fasteners & Bolted Connection Hardware: High-strength structural bolting sets Grade 8.8 / 10.9 per EN 14399 / EN 15048 and corrosion-resistant bi-metal self-drilling fasteners.

Building Physics & Export Logistics

Fire Resistance & Acoustic Performance: Fire-rated steel exit doors (EI 60 / EI 120) and insulated sectional panels
Thermal Performance & U-Values: U-values from 0.22 down to 0.11 W/m²K engineered with continuous external insulation and thermal break isolators (GEG / RE2020 / Passivhaus).
Export Delivery & Container Packing: Pre-cut and drilled jamb/header steel members with mounting hardware kits
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

Integrated industrial sectional overhead doors, high-speed roll-up doors, heavy aircraft hangar sliding gates, and thermally broken aluminum curtain wall glazing systems. Heavy lintel beams and reinforced door jamb posts transfer door equipment and dynamic wind shock loads directly into the main steel framing.

2. Lateral Wind & Seismic Ductility

Wind-load reinforced door panel guides and multi-point bottom locking bars withstand gale-force winds up to Eurocode Wind Class 4 and 5 (> 1200 Pa), preventing door blowout during severe storms.

3. Thermal Break & Moisture Control

Sectional door panels feature 40mm–80mm high-density polyurethane foam cores (U = 0.50 to 0.90 W/m²K) with double perimeter EPDM lip seals. Glazed aluminum frames integrate polyamide thermal breaks and argon-filled Low-E triple glazing (Ug = 0.60 W/m²K).
