Product Information

Full details

The Lindab Magestic Intermediate Downpipe (75mm x 1m) is an essential component for professional installers and homeowners looking to create reliable offsets or swan necks in their rainwater systems. It is specifically designed to bridge the gap between two bends, allowing for seamless connectivity when gutter outlets and ground drains are not perfectly vertically aligned. Crafted from advanced galvanised steel with a magnesium zinc alloy coating, this product offers superior corrosion resistance, particularly in coastal environments, though users should be prepared for the natural 3-5 year weathering process that transitions the initial finish to a matte dark grey.

FAQs

Can I paint this pipe?

Yes, it can be painted if you wish to change the color immediately, though the natural weathering process is intended to provide a long-lasting finish without maintenance.

Does it need a sealant at the joints?

Generally, Lindab downpipes are designed as a push-fit system and do not require sealant if correctly installed and aligned.

How long will the finish take to turn dark grey?

The surface will typically weather and transition to its final dark grey metallic matte finish over a period of 3 to 5 years.

Is this suitable for inland use?

Yes, while specifically engineered for coastal excellence, its durability makes it an excellent, long-lasting choice for any environment.

What tools are needed to cut the pipe?

A standard fine-tooth hacksaw or a metal nibbler is sufficient for cutting the pipe to size.

Troubleshooting

Pipe does not fit snugly into the bend

Ensure no burrs or metal shavings remain on the cut edge of the pipe after trimming.

Visible surface rust after installation

Small areas of surface oxidation are part of the self-healing process; these will stabilize as the magnesium zinc coating seals the area.

Pros and Cons

Pros

  • Superior corrosion resistance in saline and coastal climates
  • Self-healing coating technology for minor surface abrasions
  • Environmentally sustainable steel construction
  • Easy to integrate into existing 75mm Lindab systems

Cons

  • Surface appearance changes significantly over the first 3-5 years
  • Requires professional fitting for optimal alignment and seal
  • Not intended for use as a standalone pipe without appropriate bends

Setup, Compatibility & Care

To install, measure the required length between your two bends, allowing for the necessary insertion depth into the fittings. Use a fine-tooth hacksaw or nibbler to cut the steel pipe to the desired length. Always file down burrs after cutting to ensure a smooth connection.

  • Compatibility: Designed specifically for the Lindab 75mm system. It is recommended to use only genuine Lindab accessories to ensure a watertight fit.
  • Care: Avoid contact with copper components, as this can cause galvanic corrosion. If the pipe is cut, there is no need to apply paint to the edge, as the Magestic coating is designed to self-repair. Simply ensure the system remains clear of debris to maintain optimal flow.
