SL Aluminium Downpipes

A robust, versatile choice for a variety of projects, our SL Aluminium downpipes are suitable for heritage properties and new-builds alike, and boast a service life of over 30 years.

Manufactured from quality aluminium alloy to EN AW-6063 T5 T6 BS EN 12020 – 2:2001, our SL Aluminium downpipes have an average lifecycle of 30+ years which can be extended with proper maintenance, ensuring that your new rainwater system will not require replacement for many years to come

Offering the same high standard of quality on show across our SL Aluminium range, our SL Aluminium downpipes are corrosion-resistant, available in standard sizes of 75mm or 100mm dia and 1,2 or 3-metre lengths. With stock readily available in our warehouse in Leeds, quick delivery can be assured for projects on tighter timescales.

Colours & Finishes

Our SL Aluminium downpipes come as standard in black textured polyester powder coating, providing years of maintenance-free service, with textured white and lead grey also available at a small premium. Other BS5252 (inc BS4800) or RAL colours are available in a smooth finish, with a textured finish also available where quantity allows.
