Niagara Round - Internal Corner

Niagara Round System - gutter components, with a classic, semi-circular profile. Steel corner, external, 90-degree angle.

Internal corner – NIAGARA Round

The steel gutter system proposed by our company is a complete drainage system – perfect for any roof, intended for new and renovated buildings, regardless of the type of roofing.

The undoubted advantage of coated steel gutters is their high resistance to mechanical damage.
The use of polyurethane as a protective coating, which has excellent performance parameters (high corrosion resistance and color fastness), ensures reliability for many years. The offered gutters are deeper, so they can collect more rainwater without fear of overflow.
The internal corner allows you to connect the gutter at the corners of the building. The standard angle for this element is 90 ^degrees. Our offer also includes corners with an angle of 135 degrees ⁽ both internal and external), and upon special request, we can make corners with a non-standard angle.

System Configurations

Types of systems

The versatile use of NIAGARA steel gutters makes them available in many configurations, adapted to various types of buildings. The choice of the type of system depends on the type of construction and the roof surface. Depending on the roof surface, two-pipe systems can be used to optimize water drainage efficiency. It is worth noting that not all of our systems are available in all configurations. The following systems offer the widest range of possibilities: NIAGARA Round and NIAGARA Galvanized

Technical Specifications

Technical data and cross-section

The corner allows you to connect the gutter in the corners of the building. The standard angle for this element is 90 ^degrees . The unique stamping technology allows you to make corners (90 ^° ) without the need for welding (does not apply to a depth of 190), which significantly affects the aesthetics of the building. Corners and gutters are connected using a gutter connector, available in our system offer.

note * The 190mm variant is welded and powder coated.
