Downpipes can be produced to suit project-specific size requirements, with 100 mm square being the most commonly specified standard for a wide range of industrial and commercial applications.

Alongside straight pipe lengths, we supply a full selection of compatible fabricated components including outlets, collars, swan necks, brackets, and shoes, allowing a complete and coordinated rainwater system to be achieved from a single source. Each element is designed to ensure straightforward installation while maintaining a clean, consistent appearance across the building façade.

Our square downpipes are typically manufactured from 0.7 mm thick material, offering a balance of durability and neat visual finish. They can be finished to either complement the surrounding cladding colour for a subtle, integrated look or specified in a contrasting colour to create a defined architectural feature.

Combining flexibility in sizing with a full range of matching fittings, Thomas Panels and Profiles square downpipes provide a practical and visually cohesive solution for modern rainwater management systems.
