Product Information

Full details

The Lindab Magestic Half Round Gutter (100mm x 3m) is an advanced rainwater solution designed for homeowners and professionals seeking extreme corrosion resistance in challenging environments, particularly coastal regions. Engineered with a proprietary magnesium-zinc alloy coating, it provides up to 20 times the corrosion protection of standard galvanised steel while maintaining an eco-friendly profile. Users should note that the finish undergoes a natural transformation, shifting from a bright metallic shine to a sophisticated dark grey appearance over the first 3-5 years of exposure.

Extended Product Information

FAQs

Does the gutter come in colors other than metallic?

No, the Magestic finish is a specific metallic alloy coating designed to weather into a dark grey appearance over 3-5 years.

Is this product suitable for seaside homes?

Yes, the magnesium-zinc coating is specifically formulated to resist chlorine and salt, making it excellent for marine environments.

What is the warranty period?

The Lindab Magestic gutter system comes with a 10-year manufacturer warranty.

Can I paint these gutters?

While the finish is designed for durability as-is, painting is generally not recommended as it may interfere with the proprietary self-healing properties of the coating.

What is the primary difference between Magestic and standard galvanised steel?

Magestic uses a magnesium alloy that offers 20 times the corrosion resistance of standard galvanised steel and features self-healing edges.

Troubleshooting

Visible red rust at cut edges immediately after installation

This is often a temporary surface reaction. The self-healing magnesium properties will form a seal over the edge within a short period of exposure to the elements.

Gutter joints leaking

Check that the joints are fully seated within the cup diameter and ensure any required seals are correctly compressed and free of debris.

Pros and Cons

Pros

  • Exceptional corrosion resistance compared to standard galvanised steel
  • Self-healing coating technology mitigates rust at scratch points
  • Eco-friendly production process with reduced zinc usage
  • Robust performance in marine and high-chlorine environments
  • Includes a 10-year manufacturer warranty for long-term peace of mind

Cons

  • Appearance changes significantly over the first few years
  • Requires professional installation for optimal sealing
  • Available in specific size tiers which may require precise site measurement

Setup, Compatibility & Care

Installation of the 100mm Lindab Magestic system should follow standard rainwater system protocols. Ensure all components are handled carefully to avoid deep gouges that exceed the self-healing capacity of the coating. For best results, use compatible Lindab connectors and brackets specifically designed for the 100mm half-round profile.

For maintenance, clear the gutters of organic debris such as leaves and twigs at least twice a year. Avoid using harsh chemical cleaners or abrasive wire brushes, as these can disrupt the natural protective layer. A simple rinse with clean water is sufficient to maintain the system's integrity over its 10-year warranty period.
