The Anodized Hammer PV Profile 40×40 is the premium variant in the ULAMEX 40×40 mm mounting rail range, combining two features that professional installers and project specifiers increasingly demand together: a T-slot channel for rapid hammer-bolt assembly and a black anodized surface finish for architectural visual integration. Extruded from EN AW-6060 T6 aluminum alloy, this solar mounting rail delivers the same structural performance as all 40×40 profiles in the ULAMEX programme while offering both the fastest available on-rail fastener engagement and a UV-stable, maintenance-free black appearance that harmonizes with dark-framed and all-black solar panels. ULAMEX supplies this profile at B2B wholesale conditions with European delivery for installers, distributors, and project developers who refuse to compromise between speed, aesthetics, and durability.
Technical Specifications
The Anodized Hammer PV Profile 40×40 combines the T-slot extrusion geometry of the Hammer PV Profile with the black anodized surface treatment of the Anodized PV Profile. All mechanical and dimensional properties are maintained:
- External dimensions: 40 mm × 40 mm
- Material: EN AW-6060 T6 (AlMgSi, material number 3.3206)
- Minimum tensile strength: 190 MPa
- Minimum yield strength (Rp0.2): 150 MPa
- Minimum elongation: 8%
- Weight per metre: approximately 0.80–0.90 kg/m
- Channel type: T-slot channel (upper) — for T-bolts and sliding inlets with ball retention
- Upper channel fastening: M8 T-bolts (hammer-head), M8 sliding inlets with ball retention
- Base fastening: M10 hex bolts (DIN 933) with M10 flange nuts (DIN 6923)
- Surface finish: Black anodized (electrochemical aluminum oxide, 15–25 µm)
The black anodized layer is formed through an electrochemical oxidation process that converts the aluminum surface into a hard oxide layer integrated with the base metal. The black pigment is introduced into the porous oxide structure before sealing, creating a colour that is inherently UV-stable, scratch-resistant, and will not peel, flake, or degrade over decades of outdoor exposure. The anodization does not alter the T-slot channel dimensions or fastener engagement — all T-bolt and sliding-inlet compatibility is preserved exactly as in the mill-finish hammer variant.
Dimensional tolerances conform to EN 755-9. The combined anodized-hammer specification means this single profile delivers everything a premium PV installation requires: rapid assembly, premium aesthetics, and enhanced corrosion protection.
Available Lengths and Sizes
The Anodized Hammer PV Profile 40×40 is stocked in two standard lengths:
| Length (mm) | Length (m) | Approx. Weight (kg) | Typical Application |
|---|---|---|---|
| 2,220 | 2.22 | ~1.8 | Premium residential — visible roof installations, dormers, street-facing arrays |
| 6,210 | 6.21 | ~5.0 | Commercial premium — architect-specified projects, corporate headquarters, showroom buildings |
These two lengths cover the most common scenarios where the combined anodized-hammer specification is requested: compact residential rooftops with high aesthetic requirements (2,220 mm) and large-scale premium commercial installations (6,210 mm). Custom cutting to intermediate lengths is available on request. For projects needing the full six-length range (2.22, 2.50, 3.30, 4.40, 6.21, 6.60 m) with T-slot functionality, the mill-finish Hammer PV Profile 40×40 is available in all six lengths. For projects needing the full six-length range with hex-channel and black finish, the Anodized PV Profile 40×40 provides hex-channel in two lengths.
Channel System and Fastener Compatibility
The T-slot channel system in the anodized hammer profile is functionally identical to the mill-finish Hammer PV Profile 40×40. The anodization process does not reduce channel opening width or alter bolt engagement geometry. The system operates as follows:
- T-bolt insertion: Hammer-head bolts or sliding inlets are inserted through the channel opening at any point along the rail, rotated 90° to engage the internal channel cavity, and slid to the desired position.
- Ball retention: Sliding inlets with spring-loaded ball retention hold the fastener captive at the insertion point, freeing both hands for clamp positioning.
- Tightening: Standard torque wrench to specified value — no special tools required.
Compatible fasteners for the upper T-slot channel:
- M8 T-bolts (hammer-head bolts) — basic T-slot fastener
- M8 sliding inlets with ball retention — preferred for professional installations
- M8 socket head cap screws (DIN 912) — where head dimensions permit
Base channel: M10 hex bolts (DIN 933) with M10 flange nuts (DIN 6923) for connection to roof hooks and substructure brackets. All ULAMEX aluminum clamps are fully compatible with this profile.
Installation Applications
The Anodized Hammer PV Profile 40×40 is specified for installations that require both operational efficiency and visual excellence. Typical project types include:
- Architect-designed residential projects — new-build homes and renovations where the architect specifies all-black mounting hardware to complement black-framed panels, slate roofing, or dark metal cladding. The T-slot channel enables fast installation without compromising the visual specification.
- Corporate and commercial showcase buildings — headquarters, showrooms, retail centres, and public buildings where the solar installation is visible and contributes to the building’s visual identity. Black anodized rails eliminate the industrial appearance of silver aluminum on high-profile facades and rooflines.
- Listed buildings and heritage zones — installations subject to planning authority aesthetic requirements that mandate dark-coloured mounting components. The T-slot system reduces the time installers spend on heritage-sensitive roofs, minimizing disruption.
- Coastal premium installations — beachfront villas, coastal commercial properties, and marina-adjacent buildings where both premium aesthetics and enhanced corrosion resistance from the anodized layer are required.
- High-volume premium residential rollouts — housing developers specifying all-black PV systems across 50+ homes, where the T-slot assembly speed saves cumulative hours and the black finish satisfies the architectural design code.
The profile integrates with the complete ULAMEX photovoltaic mounting ecosystem: clamps, roof hooks, fasteners and connectors, ballast systems, and tilt triangles.
Why This Profile
The Anodized Hammer PV Profile 40×40 exists because the solar market increasingly demands installations that are both fast to build and visually refined. Previously, specifiers had to choose between speed (hammer T-slot) and aesthetics (black anodized) — this profile eliminates that trade-off.
In the ULAMEX 40×40 range, the four variants serve distinct project requirements:
- Standard PV Profile 40×40 — lowest cost, hex channel, mill finish. Best for: budget-conscious residential and commercial projects where aesthetics are secondary.
- Anodized PV Profile 40×40 — hex channel, black anodized. Best for: aesthetic projects with moderate installation volumes where T-slot speed is not critical.
- Hammer PV Profile 40×40 — T-slot channel, mill finish. Best for: high-volume projects prioritizing speed where rail appearance is not a concern.
- Anodized Hammer PV Profile 40×40 (this product) — T-slot channel, black anodized. Best for: premium projects requiring both speed and visual excellence.
The premium over the mill-finish hammer variant reflects the anodization process cost. For projects where the black finish is a must-have specification (architect requirement, planning authority mandate, or client preference), this premium is unavoidable and delivers measurable value through permanent UV-stable colour and enhanced corrosion resistance.

Frequently Asked Questions
Does the black anodized finish affect T-bolt insertion and sliding?
No. The anodized layer (15–25 µm) is negligible relative to the T-slot channel dimensions. T-bolts and sliding inlets insert, rotate, and slide with the same ease as in the mill-finish hammer profile. The anodized surface actually provides a slightly smoother, harder channel surface that can improve fastener sliding during positioning.
Why is this profile only available in 2 lengths while the mill-finish Hammer profile has 6?
The anodized hammer variant serves a more specialized market segment (premium aesthetic + rapid assembly) compared to the mill-finish hammer profile, which is the volume workhorse for all installation types. The two stocked lengths — 2,220 mm and 6,210 mm — cover the most common project scenarios for this specification level. Custom cutting from the 6,210 mm length can produce any intermediate dimension. If your project requires the full six-length programme with T-slot channels, the mill-finish Hammer PV Profile 40×40 is the appropriate choice.
Is this profile suitable for coastal installations?
Yes, and it is one of the recommended specifications for coastal environments. The sealed anodized aluminum oxide layer provides significantly enhanced resistance to salt spray and atmospheric chlorides compared to mill-finish aluminum. Combined with the inherent corrosion resistance of the EN AW-6060 T6 base alloy, the anodized hammer profile is well-suited for installations within 5 km of the coastline (corrosivity category C3–C4 per EN ISO 9223).
Can I pair this profile with silver (mill-finish) clamps?
Structurally, yes — ULAMEX aluminum clamps are compatible regardless of the profile surface finish. However, mixing black anodized rails with silver mill-finish clamps creates a visible colour contrast on the completed installation. For a fully monochrome appearance, use black anodized clamps (where available) or ensure the clamps are hidden beneath the module frames in the final assembly.
