Availability: InStock

To combat abrasion and corrosion, we use 6063-T6 or 6005-T5 aluminum with an anodized oxide layer between 15–25 microns, offering surface hardness around HV 250. This oxide film, formed via Type II/III anodizing, is molecularly bonded to the substrate, delivering high resistance to mechanical wear and chemical exposure. Conformance is ensured with ASTM B580 und ISO 7599 standards for anodized aluminum stair nosing.

Materialien

High-strength EN AW-6063-T6 or EN AW-6005A-T5 extruded aluminum for structural and fatigue stability.

Surface Finishes

Hard anodized oxide layer, 15–25 μm thick, with matte or brushed finish for abrasion resistance.

Compliance Standards

Fully meets ADAAG, ISO 23599, ASTM B221, EN 755-9, RoHS, and REACH regulatory and dimensional standards.

Cross-Section Area (A)

Typically ranges from 280–350 mm² depending on profile shape and structural reinforcement geometry.

Mass per Meter (m)

Mass varies between 0.75–0.95 kg/m based on extrusion width and anchor configuration.

Product Description

Profiles are precision-machined with linear anti-slip grooves, achieving COF ≥ 0.6 (dry), ≥ 0.8 (wet) as per ASTM D2047 und BS 7976-2. Insert-compatible channels allow for tactile infills like PVC or carborundum. Edge contrast supports ADAAG 4.9.2 und ISO 23599 compliance, enhancing visibility and accessibility in low-light or high-traffic applications.

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.

Technical Advantages

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.

Industry Applications

Transportation Terminals

Used in high-footfall areas to resist abrasion, provide slip resistance, and meet ADA/ISO safety compliance under continuous passenger traffic.

Educational Institutions

Installed on concrete or terrazzo stairs to reduce wear, enhance edge visibility, and comply with tactile surface and contrast standards.

Healthcare Facilities

Supports hygiene protocols with sealed anodized surfaces; resists disinfectant chemicals and integrates with anti-slip insert systems for safe mobility.

Commercial Buildings

Ensures edge definition and mechanical stability on tiled staircases with precision-milled anchoring profiles to accommodate diverse substrate materials.

Public Housing Complexes

Prevents stair tread erosion and material delamination in multi-dwelling structures exposed to daily impact loads and fluctuating temperature zones.

Industrial Facilities

Withstands impact from steel-toe footwear and industrial cleaning agents; maintains dimensional stability under thermal expansion-contraction cycles.

Limited Profile Versatility in Architectural Integration

Profiles are available in constant and variable sections, including angular (30°–60°) and radiused transitions (R3–R10). Manufactured to DIN 7168 fine tolerances, these extrusions integrate precisely with concrete, stone, and composite tread systems.

To avoid insert failure, channels are engineered with mechanical interlocks and bondline control features. Adhesive interfaces achieve >2.5 MPa pull-off strength and pass 1000-hour aging tests at 80°C and 95% RH. Capillary break geometry prevents adhesive migration and moisture ingress during service.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure consistent anodized finish across high-volume stair nosing batches?

Frigate uses PLC-controlled anodizing lines with real-time voltage and temperature monitoring. This keeps oxide layer thickness within ±2 microns and color deviation below ΔE 1.5. Each batch is validated with spectrophotometry to ensure uniformity in appearance and corrosion resistance.

What profile geometries does Frigate offer for retrofitting damaged stair treads?

Frigate supplies L-shaped, bullnose, and asymmetric nosing profiles with pre-drilled anchor patterns. These geometries allow direct mounting over worn concrete, wood, or stone stairs without altering the substrate. Tolerances of ±0.1 mm ensure seamless integration during retrofitting.

How does Frigate’s stair nosing design reduce mechanical fatigue in heavy traffic zones?

Frigate designs extrusions using FEA to simulate point load and repeated footfall over 1 million cycles. Stress concentrations are minimized using rounded corners and load-dispersing channels. This prevents microcracks and profile deformation over long-term use.

What steps does Frigate take to ensure insert retention under variable humidity conditions?

Insert channels are engineered with interference-fit ribs and moisture escape vents. This keeps the insert locked even with material expansion or contraction. Adhesive-bonded inserts are tested under 95% RH at 80°C for 1,000 hours to confirm long-term reliability.

How does Frigate's stair nosing support electrostatic control in cleanroom environments?

Frigate offers anodized stair nosing with antistatic surface treatment that maintains surface resistivity in the 10⁶–10⁹ ohms range. This supports ESD-safe compliance for cleanroom and semiconductor environments. Profiles are compatible with epoxy and conductive floor coatings.
