The Lindab Magestic Rectangular Gutter is an ideal choice for homeowners and builders seeking a durable, high-performance drainage solution that blends modern aesthetics with Swedish engineering. Its primary benefit is the advanced magnesium zinc alloy coating, which offers self-healing corrosion resistance, ensuring longevity even in harsh saltwater environments. While it provides a sleek, contemporary look with its natural patina finish, users should note that the unpainted surface will darken over time rather than remaining bright silver.

No, the magnesium zinc alloy coating is specifically engineered to meet ISO 9227 standards, providing excellent protection against saltwater corrosion.
The Magestic line features a natural finish that develops a dark patina over time. It is not intended to be painted.
The system is lightweight and designed with a roll-formed bead for straightforward assembly, though basic metalworking skills are recommended.
Maintenance is minimal. We recommend cleaning out leaves and debris at least once or twice a year to ensure proper drainage.
No, you must use accessories specifically designed for the 140mm rectangular profile to ensure a watertight fit.
Due to its superior alloy coating and self-healing properties, it is built to be a long-term, high-durability solution for drainage.
Check that the gutter sections are fully seated into the roll-formed bead and that no debris is obstructing the connection.
Ensure that any edges cut during installation are properly treated with a cold-galvanizing touch-up paint to protect the exposed steel.
Verify that bracket spacing conforms to the recommended layout and that all mounting screws are tightened to the structural fascia.
For installation, ensure you have the appropriate rectangular gutter brackets compatible with the 140mm profile. The 3-meter length can be cut to size using standard metal-cutting tools; however, always seal any field-cut edges according to the manufacturer's recommendations to maintain the integrity of the coating. The system is virtually maintenance-free, requiring only occasional clearing of leaves and debris to ensure unimpeded flow. Because the material is designed to develop a natural patina, no painting or chemical sealing is required or recommended. Avoid using harsh abrasive cleaners that could damage the surface alloy.
