Product Information

Full details

The Lindab Steel Intermediate Downpipe is an essential component for professional roofers and homeowners looking to create precise offsets or swan necks in their guttering system. Designed specifically for the Lindab Rainline Steel Rainwater system, this 100mm diameter pipe allows for seamless alignment between gutter outlets and ground drains. While it offers exceptional durability and a sleek aesthetic, users should note that it requires specific cutting tools to achieve a clean finish when customizing the length for non-standard building dimensions.

Extended Product Information

FAQs

Can I cut this pipe with standard PVC cutters?

No, you must use a metal-cutting tool like a hacksaw or an angle grinder designed for steel.

Is this pipe compatible with other manufacturers' gutters?

It is specifically designed for the Lindab Rainline system; compatibility with other brands is not guaranteed and not recommended.

Does the brown color fade over time?

The coating is designed to be UV-resistant and weather-stable, maintaining its color integrity for many years.

How do I secure the pipe to the wall?

Use official Lindab downpipe brackets spaced at regular intervals according to the system's installation guide.

Can this be used for internal plumbing?

No, this product is specifically engineered for exterior rainwater drainage systems only.

Troubleshooting

Difficulty inserting pipe into fittings

Ensure the cut edge of the pipe is filed smooth and free of burrs.

Visible surface scratch after installation

The coating is designed to self-heal, but you may use a Lindab-approved touch-up paint if the scratch has penetrated to the bare metal.

System feels loose at the joints

Check that all Lindab mounting brackets are tightened securely to the wall and that the pipes are seated to the full depth of the fitting.

Pros and Cons

Pros

  • High-quality steel construction offers excellent longevity
  • Self-healing coating prevents long-term rust damage
  • Minimal thermal movement ensures tight, leak-free joints
  • Lightweight and easier to work with than cast iron alternatives
  • Suitable for a wide range of building styles

Cons

  • Requires professional cutting tools for custom lengths
  • Less forgiving than flexible plastic piping during initial alignment
  • Part of a proprietary system requiring Lindab-specific fittings

Setup, Compatibility & Care

To install, measure the required distance between your bends and mark the pipe accurately. Use a fine-tooth hacksaw or an angle grinder with a metal-cutting disc to trim the pipe to size, then deburr the edges to prevent rust. Ensure the pipe is inserted fully into the adjacent fittings to maintain structural integrity. For care, keep the system free of large debris like leaves to prevent blockages. The pipe is part of the integrated Lindab Rainline system; ensure all brackets and fasteners used are also from the Lindab steel range to maintain the integrity of the protective coating. Periodic visual inspections for any major impact damage will help maintain the self-healing coating’s effectiveness.
