Alumasc Guardian - Square Aluminium Security Left Branches

Note: Please ensure you select the relevant Guardian Downpipe variant (circular, square, or rectangular profile, and where applicable orientation such as forward, backward, left, or right bends).

The Alumasc Guardian range of aluminium security downpipes is a vandal-resistant rainwater system designed for security-conscious environments such as schools, hospitals, transport hubs, and other public buildings. Available in circular, square and rectangular profiles, the Guardian system offers a complete set of components including standard downpipes, make-up pieces, bends (forward, backward, left and right in 92.5°, 112.5° and 135° angles), access pipes, fixed offsets, 2-part offsets (305mm, 533mm and 762mm projections), shoes, and rectangular hoppers.

Guardian downpipes feature concealed brackets and jointing, creating a flush fit to the wall. This design makes them ungrippable, vandal-resistant, and highly secure, while maintaining a neat and contemporary appearance. Hoppers are fabricated from aluminium sheet, with weld marks visible around the base as part of the manufacturing process.

Manufactured from high-quality aluminium, Guardian downpipes are lightweight, durable and resistant to corrosion and impact damage. The system provides a service life expectancy of up to 40 years in rural or suburban areas, and up to 25 years in industrial or marine environments.

All Guardian products are made-to-order bespoke systems with an approximate 4-week lead time. They are available in plain mill finish for on-site painting or factory-applied BBA-approved polyester powder coatings in 26 standard colours, with additional BS and RAL colours available on request. As with all Alumasc aluminium rainwater systems, the Guardian range is 100% recyclable, combining sustainability with security.
