ATT Flat bottom channel drainage

Flat bottom channels belong to standard drainage solutions manufactured in a wide range of dimensions. By standard, they are produced of sheet metal of 2 [mm] thickness made of AISI304 or AISI316 grade steel for production. The drains have built-in bottom slope, varying between  0,5 to 1%, depending on project demands, and can be further ajusted if necessary. Each channel is equipped with leveling feet and anchoring elements. They allow correct levelling of the drainage and its settling in concrete. Flat bottom channel are generally installed where floor height is limited, as due to their design they require less space for installation.

The outlet of the channel is equipped with a trap and a waste basket, which secure the sewage system against solid contamination. The drainage part is also equipped with a flange, which can be supplemented with a horizontal insulation.

Such a solution ensures tightness at the point where the outlet passes through the ceiling.
