Alpine Tray Roofing – SS675 Architectural Profile

Alpine tray roofing is a concealed-fix metal roofing and wall cladding system designed for architectural buildings and demanding environmental conditions across New Zealand. Freeman Roofing’s Alpine Tray SS675 profile provides strong architectural lines, high water-carrying capacity, and structural performance suited to residential and commercial projects.

The system is manufactured custom cut to length (subject to transport and site limitations), allowing sheet lengths to be tailored to project requirements. Alpine Tray is part of Freeman Roofing’s broader range of metal roofing profiles designed for architectural and commercial applications.

Key Features of Alpine Tray Roofing

Freeman Roofing Alpine Tray SS675 offers several advantages for architectural roofing and wall cladding systems:

• Concealed clip fixing system with snap-lock installation

• Rib height of approximately 44 mm providing strength and water-carrying capacity

• Effective cover width of approximately 455 mm

• Suitable for both roofing and wall cladding applications

• Available in a wide range of COLORSTEEL® colours

The deeper rib profile creates strong shadow lines and a bold architectural appearance, making Alpine Tray a popular choice for modern building designs.

Minimum Roof Pitch

The minimum roof pitch for Alpine Tray roofing is 3°, when the system is designed and detailed in accordance with Freeman Roofing SS675 design details and recognised New Zealand compliance pathways.

Low-pitch roof applications require appropriate detailing and installation to ensure adequate drainage and weather performance.

Typical Applications

Alpine tray roofing is commonly used for:

Architectural Residential Roofing

Modern homes where a bold standing seam style roof profile is desired.

Alpine and High Rainfall Regions

The deeper rib height provides increased water-carrying capacity and improved performance in demanding environments.

Wall Cladding Systems

Alpine Tray can also be used as architectural wall cladding when installed with an appropriate drainage cavity and support system.

Important Design Considerations

Correct detailing is essential to ensure the long-term performance of tray roofing systems.

Thermal Movement

Metal tray roofing expands and contracts with temperature changes. Detailing must allow for thermal movement across the roof system.

Oil Canning

Alpine Tray roofing may show visible waviness depending on lighting conditions, substrate stiffness, tray width, and viewing angle. This visual characteristic, known as oil canning, is inherent in wide flat-pan tray profiles and is not considered a defect.

Wind Zones and Substrate

Substrate requirements may vary depending on wind zone, exposure conditions, tray width, and material selection.

Material selection may include products such as COLORSTEEL® depending on project requirements and environmental conditions.
