Laying out a complete roof drainage system requires maneuvering gutters around every element of the roof. With highly irregular structures, the use of special connections will be necessary. One such connection is the external 90° corner, which complements a very similar component – the steel internal 90° corner. This way, you can connect adjacent gutters running at a right angle to each other.
Installing an external steel gutter corner can redirect water flowing off the roof slopes to the next drainage element. In this way, water will flow along the entire roof to reach the downspout of our steel gutter system. This enables the disposal of large amounts of rainwater by directing it away from the roof area, for instance, into a rainwater harvesting tank. Thus, it protects the building’s facade and the surrounding ground from the impact of the water.

The external steel 90° corner, like other drainage system components from our system, ensures the highest durability and strength. It is a stable solution that allows for the diversion of even large quantities of water during heavy downpours.
Effective connection of individual elements of the steel gutter system using 90° corners has proven successful for thousands of our customers. They praise the mechanical resilience of the gutters and corners and their resistance to weather conditions. As a result, the system has operated flawlessly for many decades without needing repairs or costly failures.
Steel gutter cross section
Our high-quality steel gutters are manufactured with four layers of protective coatings to ensure durability and performance. This superior construction includes a zinc layer applied directly to the steel for corrosion resistance. A passivation layer follows, promoting strong adhesion for the subsequent primer layer, which further enhances the anti-corrosive properties and provides a secure bond for the final layer. The organic coating tops off the system, offering ultimate resilience against adverse weather and mechanical damage while also providing the gutter with its aesthetic appeal. The comprehensive coating process is applied to both the interior and exterior surfaces of the gutter, ensuring thorough protection.
