Moment of Inertia (Ix / Iy)
Ix value around (7.5 × 10⁴ mm⁴ / 2.2 × 10⁴ mm⁴) supports high bending stiffness along stair tread direction.
Section Modulus (Zx / Zy)
Zx/Zy indicates bending stress resistance and edge durability under distributed and localized loads.
Radius of Gyration (ix / iy)
Determines column stability and section’s ability to resist buckling under axial loads.
Max. Axial Load (Euler Buckling)
Withstands 4.2 kN in vertical compression over 1 m pinned length without structural instability.
Max. Load at Slot (Shear Test)
Supports 1.6 kN shear before adhesive or mechanical failure in embedded concrete applications.
Torsional Constant (J)
J value of 950 mm⁴ controls twist deformation under eccentric and torque-induced loading conditions.
Max Torque (Torsional Load Limit)
Endures 12.4 Nm torsional load before profile yield or permanent angular distortion.
Elastic Deflection (100 N Load)
Exhibits less than 0.8 mm vertical deflection under uniform 100 N load over a 1 m span.
Dynamic Load Rating
Withstands repeated 1.2 kN cyclic loads without fatigue cracking or deformation over 1 million cycles.
Compatibility Tolerance
±0.3 mm for substrate variations, ±0.1 mm for flush fit with floor finishes.
Machining Precision Grade
Achieves ISO 2768-mK precision for hole spacing, edge finishing, and mill-cut anchoring slots.
Fatigue Life (Slot Edge)
Edge slot tested to over 1.5 million cycles under 400 N impact loading without cracking.
Thermal Expansion (ΔL @ ΔT=50°C)
Linear expansion measured at ~1.2 mm/m for 50°C change, aligned with aluminum’s thermal properties.
Slot Pull-Out Resistance
Insert anchoring resists 2.8 kN axial pull with hybrid mechanical lock and epoxy adhesive.
Max Load Bearing at Corner Joint
Mitered joints support 3.6 kN under angled stress without yielding or screw disengagement.
To reduce installation complexity, our profiles feature undercuts, dovetails, and counterbored anchor points, engineered to ±0.1 mm tolerances. Anti-capillary ribs and elastomeric interlayers manage adhesive spread and accommodate thermal or moisture-induced substrate movement. Section stiffness is validated through FEA, limiting deflection to <1 mm over 1 m span under uniform load.
Utilizing PLC-controlled anodizing lines, we maintain a color variance (ΔE) < 1.5 across batches. Surface roughness (Ra) is controlled between 0.8–1.2 µm using pre-anodizing treatments like bead blasting or mechanical brushing, ensuring both aesthetic and mechanical uniformity across high-volume installations.
