Super Grondal® — Pre‑painted Aluminum for Gutters & Accessories

Copper‑like aesthetics that last — engineered for weather, UV and pollution resistance

Super Grondal® enables a new generation of pre‑painted aluminum gutter material and accessories that are highly resistant to weather and polluting agents. Using proper sealers, installers can eliminate time‑consuming welding and achieve a long service life with perfectly sealed junctions. A new coil coating color‑shading technique gives aluminum a copper-like finish – yet, unlike copper, the color and finish remain unchanged through the years.

Key Advantages

Weather Resistant

High resistance to weather and pollutant exposure thanks to specialized coil‑coated paint.

Aesthetics

Copper‑like aesthetic achieved via advanced color shading; finish stability that remains unchanged over time.

Perfectly sealed junctions

Proper sealers eliminate welding and ensure durable, leak‑free connections.

Chrome‑free pretreatment

Coil‑coating system designed for strong paint adhesion, enhanced corrosion resistance and UV resistance. 

Lightweight

Aluminum’s specific weight is approximately one‑third that of copper or steel, enabling easier transport, faster installation and lightweight gutters.

Recyclable

Fully recyclable pre‑painted aluminum that maintains mechanical and metallurgical properties over time and does not release polluting material.

System compatibility

Use aluminum accessories to avoid galvanic corrosion; manufacture elbows, collars and other installation components with matching material.
