Standing Seam Metal Cladding

Standing Seam panel

Standing Seam

Standing Seam is what often comes to mind when people think of metal cladding. One of the most versatile cladding systems available, Standing Seam can be installed across numerous applications, from roofing to façades, soffits, and even on internal walls as an architectural feature finish. This is achieved through our expertise in forming individual panels into tapered, flat, curved, concave, or convex shapes to perfectly suit the application.

Standing Seam has gained popularity by offering architects, builders, and installers a refined aesthetic, capable of delivering the most intricate of designs and satisfying the most discerning clients. The installation of standing seam requires the protruding seams of two or more panels to overlap each other. Each panel is secured with concealed clips and then mechanically crimped together with the use of specialised tools. The concealed fixing method of the panels answers the need of those seeking a clean look and luxurious finish to their building project.

Technical Support

Architectural Cladding Suppliers are here to help you. We can manufacture and provide everything that is required to complete your project from our cladding profiles, to all the associated accessories and flashings via our sister company, PPC Flashings. For further information or support with flashings please contact the PPC Flashings team.

As every architectural project is different, if you require custom advice, we can discuss your project specifications and will work with you to fabricate to your individual requirements. For any further technical support please contact Architectural Cladding Suppliers.


Architectural Cladding Suppliers cannot guarantee that your metal panels will not experience the effects of what is commonly referred to as oil canning. Oil canning can occur on all types of metal and is not considered a panel defect. For more information please refer to our article on oil canning.

ACS recommends installing a “breathable vapour” membrane to act as a second line of defence to stop any water ingress as well as allowing the building to “breathe”. Any flashings required can be sourced from PPC Flashings.

Stop ends and/or hooks to each panel are highly recommended by Architectural Cladding Suppliers. If you are unsure, please contact us prior to ordering.

Do not continue if the installation does not seem right, contact Architectural Cladding Suppliers.
