Standing Seam is a European inspired tray roofing profile. It encapsulates the best of the traditional style roofing with the advantages of using modern technology.

A feature of Standing Seam roofing is the ability to adjust tray widths to suit the project requirements ensuring symmetry across the roof. It can also be completed in a single or double lock.

Standing seam is fixed to a solid substrate which is usually plywood. 


  • Depending on seam height, a minimum pitch of 3° or 5° is achievable.

  • Enables designers to use the profile to conform to height restrictions on most residential projects.

  • Tray widths vary from 250-510mm with an upstand of 25 or 38mm.

Smart Tray Standing seam can be manufactured in the following materials:

 - Copper

 - Aluminium

 - Bronze

 - Zinc
