Roof Drainage
ACO SPIN, Gravity roof drainage in cast iron

Flat-roof gullies are installed to drain rain water from roofs, car park decks and terraces. The collected rainwater is drained off via internal drain pipes

Roof Gullies

Gullies with pressed sealing flanges but without foul-air traps are used for the efficient drainage of roofs. ACO's modular system for this purpose consists of gullies with nominal widths of DN 70, DN 100, DN 125 and DN 150, in one-part or two-part models, plus accessories.

With the exception of the optional components for green roofs, the components are manufactured from grey iron to DIN EN 1561
