Internal corner fitting—a component that connects gutters at an internal corner of a building. It belongs to the group of horizontal components in the drainage system. Made from the same materials as the gutters, using an extrusion process, without soldering. The standard angle for this component is90°.
The Titan-zinc Natura gutters, offered by our company, are a complete and durable gutter system, ideal for both new construction projects and the renovation of older buildings and historic structures, to which it lends a classic, elegant look.
Made of raw titanium-zinc in the “Natura” finish, the system retains the material’s natural finish, which gives it a subtle charm and timeless character. Titanium-zinc is a special zinc alloy with added titanium, copper, and aluminum, which ensures high strength and resistance to changing weather conditions. This system is available in six size variants: 110/90, 125/90, 125/100, 150/100, 150/120, and 190/120, allowing it to be adapted to various needs and building types.
The Tytan-Cynk Natura system is the perfect combination of aesthetics and functionality, which not only effectively drains water but also highlights the architectural style of any building.
The versatility of NIAGARA steel gutters means they are available in a wide range of configurations, tailored to different types of buildings.
The choice of system depends on the type of building and the roof area. Depending on the roof area, dual-pipe systems can be used to optimize water drainage efficiency. Our product line also includes a wide selection of materials used to manufacture our gutter systems. In particular, the NIAGARA Titanium-Zinc gutter system is available in two variants: Natura and Patina. They share the same functional qualities and technical specifications; the difference lies in their appearance, which results from the use of specific manufacturing processes in each case.

The Pruszyński Company guarantees that each individual order will be produced in the same color (shade). However, due to the complexity of the coating processes, slight variations in shade may occur between individual shipments.
Accordingly, liability for color is limited to a single shipment.
Therefore, when reordering sheet metal for a specific batch, please be sure to indicate on the order form or inform your sales representative that this is a follow-up order and to provide a color sample.
To ensure color consistency between sandwich panels and other components, such as flashings, they should be ordered from a single supplier.
The corner piece allows you to connect gutters at the corners of a building. The standard angle for this component is90°.
A unique extrusion process makes it possible to create90-degree corners without the need for welding, which significantly enhances the building’s aesthetic appeal.

Gutters, pipes, and other system components must be transported in clean, dry, and covered vehicles. They must not get wet during transport and storage, as contact with water can trigger the initial stage of the patination process, characterized by the formation of zinc hydroxide—a white coating on the surface of the material. This phenomenon is a natural process; it does not constitute a material defect, but it is undesirable during storage for aesthetic reasons.
