Drainage systems BILKA 150 mm | Roofing center, Czech Republic

The BILKA gutter system or the controlled rainwater drainage system from the roof, also known as the rainwater collection system, performs the key function of draining water from the roof and directing its flow into the sewage system.

The BILKA gutter system is made of hot-dip galvanized sheet metal, which is protected by a multi-layer coating on both sides. This design is designed to ensure optimal material behavior over a long period of time. The connecting system of the elements is simple, fast and effective, which prevents rainwater from running down the facade of the building and also prevents its seepage into the foundations and walls of the house. This ensures overall protection of the structure and prolongs its service life.

The production of the BILKA gutter system elements is based on Swedish technology, which involves the use of high-quality Swedish steel (0.6 mm), which is galvanized on both sides (275 g/m2) and covered with two layers of paint (2×35 microns). This paint layer provides the products with a smooth surface with high color stability and reliable resistance to the effects of rainwater and air pollution.

With five layers protecting the sheet metal strip, the corrosion resistance of each element is guaranteed and provides these products with a very long service life. Overall, the BILKA system offers a long-term guarantee of durability for many years, and the only maintenance required is easy cleaning of the gutters from dirt.

The BILKA gutter system is available in two size groups (150/100, 125/90) and offers 17 color variants, which allows for individual combinations that match the color of the roof and the overall design.
