Gamrat PVC gutter systems ensure reliable rainwater drainage from any roof. They have been specifically designed for harsh and variable climatic conditions, including those found in Poland.
Proven in practice, they have gained recognition among contractors and investors, and are installed on millions of roofs. Their success is based on outstanding quality, durability, tightness, exceptional mechanical strength, and resistance to changing weather conditions, including temperature fluctuations, industrial pollution, and acid rain.

Gamrat PVC gutters stand out thanks to their deep, parabolic profile with reinforced edges that strengthen and stiffen the gutter. Combined with a perfectly smooth inner surface, this ensures excellent flow capacity.
Gamrat PVC gutter systems have been manufactured by GAMRAT SA for over 30 years and are continuously improved to meet evolving user expectations.

Performance of Gamrat PVC and Gamrat Magnat gutter systems
Before selecting a gutter system, the effective roof area should be calculated – the area from which rainwater will be drained by gutters and downpipes.
Below are the maximum effective roof areas per downpipe for Gamrat gutter systems.
To calculate the effective roof area, use the formula:
S = (B + 0,5 C) x L
Effective cross-sections
75 mm gutter – 33 cm²; 100 mm gutter – 58 cm²;
125 mm gutter – 91 cm²; 150 mm gutter – 131 cm²

| Downpipe positioning | 75/63 mm | 100/63 mm | 100/90 mm | 125/90 mm | 125/110 mm |
|---|---|---|---|---|---|
| 95 m2 | 110 m2 | 148 m2 | 205 m2 | 240 m2 | |
| 48 m2 | 55 m2 | 74 m2 | 100 m2 | 120 m2 | |
| 42 m2 | 46 m2 | 50 m2 | 80 m2 | 95 m2 |
Gamrat gutter systems – plastic gutters and downpipes
A Gamrat gutter system is a set of components designed to drain rainwater or melting snow from a building roof. A complete system with plastic gutters protects walls, foundations, and the surrounding area from water runoff. The material used is highly resistant to weather conditions and UV radiation, while also offering a very low roughness coefficient.
PVC (polyvinyl chloride) is a lightweight material, ensuring easy installation and no additional load on the roof structure. PVC gutter systems provide a complete solution for protecting buildings against water damage, and their components require no maintenance.
They do not require painting, are resistant to mechanical damage and weather conditions. Plastic gutters are also an aesthetic and functional architectural element, suitable for a wide range of buildings and surroundings. Gutter brackets and other components can be easily matched to the façade or roofing colour when properly installed on the fascia board.
