NIAGARA Square - pipes and fittings

We have created a ready-to-use, perfectly synchronized, complete through-pipe. The gutter sleeve protects the cornice from water overflowing from the flashings, and the pipe socket with a gasket has been selected to ensure a tight seal between the gutter sleeve and the downpipe. These components are carefully matched to ensure easy assembly of the entire system; together, they form a perfect whole.

The Square System is a modern rainwater drainage solution that combines a simple, minimalist design with high functionality. Its geometric form complements both modern and more traditional buildings, highlighting their aesthetic appeal and giving the overall design a cohesive look.
“One gutter—many possibilities” best captures the essence of this system. Its well-thought-out design offers flexibility in application and allows it to be easily adapted to various construction projects. This solution is designed with durability, aesthetic appeal, and effective rainwater drainage in mind.

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; therefore, our responsibility for color consistency is limited to a single shipment. When reordering sheets from a specific batch, please indicate on the order form or inform your sales representative that this is a continuation of a previous order and provide a color sample. To ensure color consistency between tailored roof tiles and other elements, such as flashings, please order them from a single supplier.
The NIAGARA gutter system, thanks to its wide range of sizes and dedicated components, allows for extensive customization to meet the needs of any project. To view the full product range and availability, please refer to the list below:

The system components are manufactured from the highest-quality steel, galvanized and coated on both sides with polyurethane (50 μm). Thanks to the use of these materials, we can be sure of color stability as well as high resistance to weather conditions. Polyurethane is characterized by very high resistance to corrosion as well as color fading.
The built-in components of the Concealed system are made of high-quality polypropylene to ensure the system’s durability and reliability for many years to come.
