About the Flat Seam System
Flat Seam provides designers with a customizable facade system that can feature almost any finish. Various aesthetics are achievable with this system, as it allows for a combination of varying panel sizes, shapes, and joint layouts with similar fabrication and installation techniques.
Our Flat Seam system comprises interlocking panels and stainless steel clips that secure the system to the substrate. These overlocking hems allow some tolerance in the system layout, making field modifications flexible and efficient.
Great for any vertical wall application or sloping roof, we can help you choose the best material, finish, panel size, and joint pattern for your project’s design and budget.
Benefits
| Material Finish Options | An excellent option for thinner materials, controlling cost |
| Material Usage | Panel sizes nest efficiently into raw material sheets |
| Installation Flexibility | Panels can be field-cut to size, improving scheduling and productivity |
| Tolerances | Hem overlap allows for ideal installation tolerances |
| Adapts to Geometry | Flat seam panels easily form to complex geometry |
