Standing Seam Tray Roofing – SS150 Architectural Profile

Standing seam 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 SS150 profile provides clean architectural lines, flexible tray widths, and reliable 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. SS150 is part of Freeman Roofing’s broader range of metal roofing profiles designed for architectural and commercial applications.

Key Features of SS150 Standing Seam Tray Roofing

Freeman Roofing SS150 offers several advantages for architectural roofing and wall cladding systems:

• Concealed clip fixing system with standing seam installation
• Rib height of approximately 38 mm providing strength and water-carrying capacity
• Variable tray widths typically between 300 mm and 510 mm
• Suitable for both roofing and wall cladding applications
• Custom tray lengths manufactured to suit project requirements

The standing seam profile creates refined shadow lines and a clean architectural appearance, making SS150 a popular choice for modern building designs.

Minimum Roof Pitch

The minimum roof pitch for SS150 standing seam tray roofing is 3°, when the system is designed and detailed in accordance with Freeman Roofing SS150 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

Standing seam tray roofing is commonly used for:

Architectural Residential Roofing

Modern homes where a clean standing seam roof profile is desired.

Low-Pitch Roofing

Projects where roof pitch is limited and a concealed-fix roofing system is required.

Wall Cladding Systems

Standing seam tray roofing 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

Standing seam 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 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® or aluminium depending on project requirements and environmental conditions.
