Anti-Vandal Aluminium Rainwater Pipe

Our High Security Aluminium Downpipe System incorporates flush fit downpipes providing an anti-climb rainwater downpipe that is designed for areas that require products with a very strong vandal resistance. They are ideal for prisons, hospitals, social housing and public buildings but also provide a modern option for rainwater pipe for contemporary properties.

Our vandal resistant downpipes are available in round downpipe, rectangular downpipe and square downpipe options. We produce four standard sizes of downpipe but can manufacture a range of sizes.

Our standard sizes are:

  • 75mm / 3"
  • 100mm / 4"
  • 75 x 50mm / 3"x2"
  • 100 x 75mm / 4"x3"


The aluminium anti-vandal downpipe system comes with a comprehensive range of fittings including, bends, branches, swan necks, offset bends, plinth offsets, and rainwater diverters are available in both standard sizes and special purpose-made fittings to suit individual projects.

We also have a range of hopper heads that look great with our range of aluminium high security downpipes.

Fixing & Brackets

These downpipes have internal joints giving clean lines and concealed secret fixings. This downpipe can be used for the most vulnerable bottom 3 metres or the whole pipe system.

Coatings & Finishes

All our aluminium rainwater pipes, downpipes and fittings are available polyester powder coated in a wide array of colours and finishes including the full range of RAL colours, BS colours, Heritage textured finishes, metallic finishes, and anodised coating.

We can also source special colours and finishes to match your project requirements or we can supply our aluminium gutters in the standard mill finish.
