Seamed Internal Gutter Angle

The seamed internal gutter angle is a crucial connecting component of the rainwater drainage system, designed to change the direction of the gutter at the internal (concave) corners of a roof. This part ensures the collection and drainage of water at the intersection of two roof slopes — in the so-called «roof valleys,» which are characterized by an increased concentration of water flow.

The product is manufactured from gutter segments connected together using the folded seam method. This manufacturing technology makes it possible to create reliable joints in sizes where pressed alternatives are unavailable. The angle is made of galvanized steel or steel with a double-sided Polyester polymer coating, which guarantees high corrosion resistance both on the inside and outside of the element.

Design Features:

• Joint Strength: Segmented assembly using the folded seam method ensures structural rigidity, making it highly resistant to deformation caused by thermal expansion of the metal and mechanical loads.
• High-Load Performance: The geometry of the internal angle is specifically adapted to handle large volumes of water flowing from two adjacent slopes, preventing the system from overflowing.
• Flexible Solutions: In addition to the standard 90-degree design, the seaming technology allows for the manufacturing of elements with custom angles and diameters (up to 190 mm) to meet specific architectural requirements.
