Standard channels

Standard channels

Standard channels are manufactured in a wide range of dimensions and shapes. They are produced according to a drawing prepared as a result of cooperation between an investor, a designer or a technologist and ATT engineers. By standard, we use sheet metal of 2 [mm] thickness made of AISI304 or AISI316 grade steel for production. The drains have built-in bottom slope, which by standard is 1%. There is a possibility to adapt the size of the slope to a specific project. Each channel is equipped with leveling feet and anchoring elements. They allow correct levelling of the drainage and its settling in concrete.


– drain large amounts of water,
– they may be easily configured and connected at required angles with other standard or slot channels,
– it is possible to apply various types of covering gratings,
– easy access for cleaning (rounded internal corners, removable gratings, waste basket with a trap),
– the channel edge can be adapted to the floor type (additional edge flanging for tiles, angle for expansion joints),
– a rodding eye is installed in the sewage system in the place of drainage.



Standard channels are defined by determining the external width (S150, S200, S220, S600 etc.).


S150 – means a channel of external width of 150 [mm].

In case of a S150 channel, the grating width will be 107 [mm], and the hydraulic width will be Sh = 78 [mm]. When determining the parameters of drainage, the basic guidelines are: the amount of discharge/type of load.


The most typical grating to cover the standard channels is hygienic ladder grating. Our products range also includes the anti-slip mesh grating, plate or perforated sheet gratings, all in different sizes and dimensions.

The gratings are selected depending on the place of installation of the channel, taking into account the load class and functionality.

In the places of intensive forklift traffic, it is recommended to install a plate or ladder grating, while in
case of large amounts of drained water – a mesh and ladder grating.




The edge finishing should depend on the flooring and wastewater temperature.
We can offer the following options:
1 – with downward flange (standard)
2 – with flange
3 – with raised back edge
4 – with edge angle section for the expansion joint in the floor
5 – with tightly plately folded edges
6 – for a vinyl floor


The following figure presents an example channel arrangement. The distribution of drains and the arrangement of the channel, depends on the needs and the amount of water collected on the floor during the technological process. There is a possibility to cross-connect the systems we have on offer.

Arrangement of the channel should be prepared by a designer in cooperation with a technologist. In case of any technical doubts related to execution of a given drainage, our consultants can assist you. 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.

    Category of interest:



    - stainless steel AISI304/316 (1.4301/1.4404)
    - the channel is defined by its external width (S150, S200 ....)
    - when determining parameters (except for its determination) should be given type and size of the slope and a drawing of the channel course in the plan
    - load classes: A15, B125, C250, D400,
    - grates: mesh (a/s), ladder (a/s, hygienic), plate, perforated
    Product use
    - in environments where a large amount of liquid is drained from the floor, while maintaining high standards of hygiene and product durability
