Round Rainwater System
SIA "Akvilon" offers round rainwater systems of its own production. This is a classic, time-tested solution that fits harmoniously into the architecture of most buildings and ensures effective collection and drainage of water from the roof.
The half-round shape of the gutter provides high hydraulic efficiency and resistance to deformation. We manufacture all the necessary components of the system, which allows us to guarantee perfect compatibility of elements and full compliance with European quality standards.
Materials and Available Colors
We produce round rainwater systems from high-quality steel, ensuring durability and reliable protection against corrosion.
- Galvanized Steel (ZN)
Thickness 0.45-0.50 mm. A traditional, strong, and economical option that provides basic rust protection.
- Polymer-coated Steel (PE)
Galvanized steel painted on both sides with polyester. This coating provides excellent protection against corrosion, UV radiation, and gives the system an aesthetic appearance.

Systems with PE coating are available in a wide range of colors. View the full color catalog (RR).
Technical Specifications and Dimensions
We offer a wide range of standard diameters, allowing you to select a system for roofs of any size—from small country houses to large commercial buildings. All components are manufactured with high precision, ensuring a tight seal and ease of assembly.

- Full Kit: We provide a complete set of installation materials, including rivets, sealant, screws, dowels, and all necessary roofing accessories in the system's color (flashings, cornices, ridges, etc.).
- Flexibility: We can manufacture custom elements and offer the ability to combine systems, for example, using profiled (square) gutters with round downpipes.
- Free Calculation: Our engineers will perform a free calculation of the system's capacity (per EN 12056-3) and prepare a quote.
- Short Lead Times (ZN): Systems made of galvanized steel (ZN) are kitted within 1-3 working days.
- Short Lead Times (PE): Systems made of painted steel (PE) are manufactured within 2-5 working days.
Installation and Components
Correct Slope is Key: The crucial aspect of gutter installation is ensuring a correct and consistent slope (usually 3-5 mm per meter). This guarantees that water flows to the funnel by gravity and does not stagnate.
Everything for Installation: We offer not only gutters and pipes, but also a complete installation kit: brackets for any roof type, corners, funnels, connectors, as well as all necessary fasteners (rivets, screws) and sealant.
Professional Installation: If you want to guarantee a perfect result, SIA "Akvilon" offers professional installation services. Our in-house specialists ensure the correct installation of all components, adherence to slopes, and sealing of joints to guarantee the efficiency and durability of the entire system.
