The aesthetically pleasing design flat-roof hopper ensures uniform and visually appealing drainage of all parts of a house. Its dimensions and compact shape make it particularly suitable for parapet drainage in buildings of different sizes. The emergency overflow on the designer flat-roof hopper is already created by cleverly positioned drainage slots. Individual structural conditions can nevertheless be taken into account, as the position of the inflow can be specified within a defined area. The overflow slots on both sides are designed so that accumulated water drains away before it backs up in the inflow pipe. Equipped with an integrated splash guard, the design flat-roof hopper virtually eliminates the possibility of unplanned water leaks from the drainage slots, even in heavy rain.... more

PAINT-COATED GUTTER OUTLETS AND HOPPERS MADE OF ALUMINIUM.

Numerous possibilities.

Plug-in gutter outlets channel rainwater away from the rain gutter and into the downpipe. They are now available from GRÖMO in paint-coated aluminium as well. With seven colours and two surface options, there is almost no limit to the possibilities for designing your façade. Anthracite, brown (Testa di Moro), light grey, white, moss green, brick red, oxide red or up to another 206 RAL paint colours available by request. The GRÖMO ALUSTAR colour assortment leaves nothing to be desired.
All GRÖMO ALUSTAR gutter outlets are corrosion-resistant, durable and extremely sturdy. They allow you to select between different connectors, making them especially suitable for a wide range of applications. The gutter outlets fit gutters with diameters between 250 and 400 mm and a drainpipe diameter of 60 to 120 mm in accordance with DIN EN 612. This means they can be combined with any drainpipe, allowing full freedom of design.

Naturally our paint-coated hoppers made of aluminium are included too. They are suitable for installing on both flat and pitched roofs, whether they are rectangular or cubic, centric or eccentric, with or without overflow. The various possibilities for design are enough to satisfy any customer’s desires.

Fits any elbow thanks to spring clip technology.

Any elbow can be plugged onto the oval GRÖMO ALUSTAR plug-in gutter outlet quickly and easily without wires or rivets. The secret is innovative spring clip technology. Simply turn the elbow in the desired direction and the spring clip technology will hold it reliably in any position. Gutter outlets and elbow can also be quickly separated from each other with a simple twist. The best part is that no tools are required for either assembly or disassembly, which saves you both time and quite a bit of stress.
