Marley Alutec

What Marley Alutec does

Marley Alutec is a UK-based specialist manufacturer of aluminium rainwater, guttering, and eaves systems, operating as a trading brand under DHM Plastics Limited, a wholly-owned subsidiary of Aliaxis UK Ltd and part of the Belgian-headquartered Aliaxis Group, a global fluid-management conglomerate with 16,200 employees across more than 46 countries. Founded in 1989 and headquartered in Bedford, the company manufactures marine-grade aluminium products (LM6 castings, 6063 T5 extrusions) including gutter systems (Evolve, Traditional, Aligator), downpipe ranges (Tudor, Flushfit, Traditional, Vandal Resistant), aluminium hoppers, the Evoke fascia/soffit/coping system finished with Kynar 500 fluorocarbon PVDF coating, and a full roof, parapet, balcony and car park outlet range. Products carry a stated 50+ year functional life expectancy, are 65% lighter than cast iron, are available in 19 standard colours including a proprietary Heritage Black textured cast-iron-replica finish, and are certified to ISO 14001:2015 and the relevant BS/EN standards (BS 8530:2010, BS EN 12056-3, BS EN 1462, BS EN 1253-2, BS 476 fire ratings).

The company serves UK-based specifiers, contractors, housing associations, and property owners across eight defined verticals — heritage/conservation, social housing, private housing, educational, coastal, self-build, healthcare, and places of worship — using a specification-led sales model that targets architects through RIBA-accredited CPD seminars, BIM/CAD parametric objects, BS EN 12056-3-compliant online roof drainage calculators, and direct technical support. Distribution runs primarily through the UK builder merchant network, where estimates are routed to local merchant partners for pricing and availability, complemented by direct sales support via phone, email ([email protected]), and 2-day direct-to-site delivery on popular products. Revenue mechanics are one-time hardware sales with quote-based pricing, downloadable price lists, and merchant discounts; there is no recurring or subscription revenue component and no publicly disclosed revenue figure.

As part of the broader Aliaxis Group, Marley Alutec operates as the UK-focused aluminium rainwater specialist within a global fluid-management conglomerate, with no independent financial reporting, no M&A activity disclosed, no funding rounds, and no operational expansion outside the United Kingdom in the source data. The company's competitive position rests on marine-grade aluminium durability, heritage aesthetics, broad multi-vertical coverage, and specification-channel depth rather than on technology differentiation or recurring revenue.

Broad incumbents

• Kingspan Water & Energy: Large UK/Irish building envelope group with rainwater and roof drainage solutions. Comparable in scale and channel reach even though its core focus is insulation and roofing.

• Lindab Rainline: Pan-European building products group offering steel and aluminium rainwater systems. Comparable gutter/downpipe products and broader construction product portfolio.

Direct peers
