ACO 19013 | CorTen Corner Unit

Weathering Steel Corner for a 90 Degree Change of Direction

The ACO 19013 turns an ACO Threshold Drain run through 90 degrees. It carries a CorTen steel grating, which ACO also supplies on the straight channel, so a run keeps one finish. ACO notes that CorTen develops its rust-coloured surface only after exposure to rainwater, so the grating may look smooth silver-grey when it is first delivered.

Specifications

Key Design Features

The grating lifts out, so the corner can be cleared without disturbing the channel either side of it. Its 5mm slots are narrow enough for ACO to class the grating as HeelGuard. The CorTen finish is the point of difference. The steel colours itself in the open air rather than being coated, so the corner ages with the rest of the run.

Benefits

Matches CorTen channel gratings, so a run keeps one finish through the corner.
5mm slots suit doorways and patios where people walk straight across the drain.
Removable grating gives access to the corner, which is where debris collects.
Weathered rust finish sits well with timber and darker stone.

Applications

Use the ACO 19013 where a Threshold Drain run turns a corner and the specification calls for weathered steel. ACO warns that rainwater running off CorTen can be brown in colour and can stain porous surfaces, particularly lighter tones, so keep it away from pale stone paving and light render.
