Pipes and Fittings. A reducing T-connection is a vertical component of a drainage system. It is indispensable when there is a need to connect downpipes of different diameters into a single drain line. The NIAGARA system offers a titanium-zinc version in size 100/90 (for connecting pipes with diameters of 90 and 100 mm).

The Titan-zinc Natura gutter system, offered by our company, is 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 appearance.
Made of raw titanium-zinc in the “Natura” version, the system retains the material’s natural finish, which gives it a subtle charm and timeless character. In the “Patyna” version, it is factory-matte-finished and undergoes a controlled aging process.
Titanium-zinc is a special zinc alloy containing 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 Patina variant, on the other hand, offers a unique, slightly matte, rustic look that pairs perfectly with stylish buildings inspired by traditional forms.

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 components of the NIAGARA titanium-zinc system are manufactured from a top-quality alloy consisting of a precisely defined mixture of steel, titanium, and zinc, with an admixture of copper. By using these materials, we can be certain of achieving the highest resistance to weather conditions as well as unique performance characteristics. A T-connection is a specialized component of a gutter system used to connect downpipes of different diameters. It is available in only one size—100/90—and allows for connections between 100 mm and 90 mm in diameter. Please check the size availability for NIAGARA-AVAILABILITY
A T-connection allows you to connect 90-mm-diameter downpipes to a single 100-mm-diameter drain line. It is useful when you want to drain water through a single downpipe.

The Niagara TYTANIUM system is manufactured from the TYTANIUM Pruszyński Company metal alloy, which consists of aluminum, titanium, molybdenum, manganese, and chromium. Thanks to the use of aluminum, the gutters are lightweight and resistant to aging and erosion. Aluminum’s low melting point allows it to be alloyed with titanium, and the presence of titanium in the alloy significantly increases its strength. The presence of chromium, on the other hand, enhances resistance to corrosion and the effects of salt.
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.
