Hook

The ROUND galvanized gutters offered by our company are a complete gutter system—designed specifically for industrial projects, though they are also ideal for residential buildings. It is designed for both new and renovated buildings, regardless of the type of roofing.
As noted above, NIAGARA GALVANIZED is a product that offers a more attractive price while retaining the key advantages of NIAGARA gutters. The system is available in eight sizes (gutter / downspout). The sheet metal from which it is manufactured is 0.6 mm thick, while the zinc coating is 275 g/m².
The 320mm Longer Wulst Hook is the longest hook in the NIAGARA Galvanized system. It was designed specifically for steep roofs (45 degrees and steeper), where it is recommended to lower the gutter to prevent damage from sliding snow. Additionally, it ensures trouble-free assembly of the gutter system when the eave structure does not include a fascia board.

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

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 a white film on the surface of the material.

The Pruszyński Company guarantees that each individual order will be produced in the same color (shade). For products made of galvanized sheet metal, variations in shade are not possible due to the nature of the raw material (galvanized sheet metal). However, we recommend contacting your distributor each time to ensure that the specific product range is available in the selected material and size.
