The popular color-coated steel system Robust will receive a comprehensive system update and a new name in 2025. Zambelli COLORDUR will be unveiled to a broad audience for the first time at BAU 2025. In addition to a refined surface texture, the complete drainage system boasts numerous optimizations and enhancements.

The steel core of the COLORDUR system can be described as a high-performance material from multiple perspectives. It provides the roof drainage system with excellent shape stability and load-bearing capacity while combining user-friendliness, modern aesthetics, and ecological considerations. A ZM120 corrosion protection coating and a 35µm structured paint system ensure reliability and durability, even under harsh conditions.

Special emphasis was placed on color consistency across the entire system, precise fit, and processing quality during the product line's evolution. Feedback and ideas from craftsmen and trade professionals were integral to this development process.

COLORDUR will be available in the following color lines: black (approx. RAL 9005), anthracite (approx. RAL 7016), brown (approx. RAL 8019), dark gray (approx. DB703), and silver (approx. RAL 9006).

The new square hopper impresses with its modern design as an elegant solution for flat roof drainage. The model, featuring a three-sided continuous bead, stands out with its premium appearance free from disruptive edges, as the optimized 3D base plate is seamlessly joined with the casing. It is available in both centered and off-centered versions.

The cubic design of the hopper without a bead in the offset connection version impresses with its clean appearance, combining modern design with high functionality and quality. The cubic water collection box is ideally suited for direct wall mounting on flat roof structures.

Optionally, the cubic hopper is also available with a bead.

The Zambelli HSF Ballast Tank is a substructure designed for the proper and secure installation of photovoltaic systems on flat roofs. Made from UV-resistant high-performance plastic (HDPE), this mounting system combines east-west elevation and ballasting in one. The pressure-free, open tank system is suitable for year-round use – even in icy conditions during winter!

Ballasting is achieved by filling the tank with water. This allows the mounting system to function without penetrating the roof membrane or requiring additional weighting with ballast stones.

An automatic precipitation return system ensures that evaporated ballast water is redirected into the ballast tank via the funnel cap during rain, keeping the water level constant.

Under the quality seal of the Zambelli compass rose and the ease of installation provided by the 3-point connection, the Zambelli Master System continues to enjoy enduring popularity.

All roofing drainage components of the system are made from the same raw material - ensuring a perfectly uniform surface.

The popular sandwich panel gutter hook is once again a highlight topic. The popular modular system is now compatible with the most common trapezoidal sandwich profiles.
