K2 mounting systems for standing seam roofs are suitable for standing seams and round seams. This system is non-penetrative and fixed with seam clamps. Clamps are available for different types of seams and manufacturers such as Kalzip or Rib-Roof. SolidRail mounting rails are used in this situation. The ClampRail system offers an exception. This is also the seam clamp and module mounting rail, and can be used for standing seam roofs.
