Standing Seam Tray Roofing – SS150 Architectural Profile

Standing seam tray roofing is a concealed-fix metal roofing and wall cladding system used on modern architectural buildings where clean lines, durability, and weather performance are required. SS150 forms part of Freeman Roofing’s wider range of metal roofing and wall cladding profiles designed for architectural and commercial projects.

The system is manufactured custom cut to length (subject to transport and site limitations), allowing tray widths and 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

The SS150 standing seam tray roofing system offers several advantages for architectural roofing and wall cladding applications:

• Concealed clip fixing system for a clean architectural finish

• 38 mm rib height providing strength and effective 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

Standing seam tray roofing is commonly specified for projects requiring a modern architectural metal roofing system with minimal visible fixings.

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 for Standing Seam Tray Roofing

Standing seam tray roofing is commonly used for:

Architectural Residential Roofing

Modern residential buildings where a clean architectural roof profile is required.

Low-Pitch Roofing

Projects where roof pitch is limited and concealed-fix roofing systems are preferred.

Wall Cladding Systems

Architectural wall cladding applications when installed with an appropriate drainage cavity and substrate.

Important Design Considerations

Standing seam tray roofing systems require correct design and installation detailing to ensure long-term performance.

Thermal Movement

Metal tray systems expand and contract with temperature changes. Therefore, detailing must allow for thermal movement.

Oil Canning

Standing seam tray roofing may show visible waviness depending on lighting conditions, substrate stiffness, tray width, and viewing angle. This visual characteristic, commonly known as oil canning, is inherent in metal tray roofing systems.

Low-Pitch Roofs

For roof pitches below 10°, purlin spacing and roof underlay support may require adjustment as part of the project-specific design.

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.
