ATT InoxDrain is the stainless steel drainage programme of ATT Sp. z o.o., a Polish manufacturing and trading company with its production plant in Kokotów near Kraków. ATT InoxDrain covers point and linear drainage, manhole and access covers and a range of hygienic accessories for floors that are washed, disinfected and loaded every day.
Stainless steel drainage has been the core of the company’s business from the start. Alongside the catalogue items, its engineers develop project-specific designs, supported by laser cutting, press brakes, robotic welding and turret punching in-house. The products are used by companies well beyond Europe, including customers in the United States, the United Arab Emirates, South Korea and Australia. Full details are available on the official ATT website and in the ATT mini catalogue (PDF).
ATT InoxDrain product lines
The range is organised around the way water reaches the sewer: through a single gully, along a channel, or through an access point that has to stay tight and cleanable. Each family is produced as standard in two stainless grades, AISI 304 (EN 1.4301) and AISI 316L (EN 1.4404), so the designer can match corrosion resistance to the effluent and cleaning chemicals on site.
Floor drains and gullies
ATT InoxDrain floor drains are offered with square frames from 100 x 100 mm up to 400 x 400 mm and round frames from 150 to 300 mm in diameter. Bodies come in one-piece or two-piece versions with a vertical or horizontal outlet, with outlet diameters from 50 to 200 mm. According to the catalogue, capacities range from 0.9 to 13.9 l/s and total heights from 58 to 440 mm, which helps when slab thickness is limited.
All parts are welded under argon shielding and then pickled. Pressed bodies without sharp corners reduce the number of welds and leave fewer places for dirt to collect. Thanks to the trap design, each gully also works as a rodding eye for the sewer below. Typical accessories include:
- gratings in anti-slip mesh, ladder, perforated sheet or plate design, chosen by load and location;
- deep-pressed waste baskets for effluent with a high solids content, or strainers where solids are few;
- inverted traps that block odours, and flanges for horizontal waterproofing layers.
For lighter duty, the WM mini series targets light industrial rooms, swimming pools, bathrooms, hotels and apartments.
Linear, slot, kitchen and bathroom channels
Standard ATT InoxDrain channels are made to drawing from 2 mm sheet with a built-in bottom slope, 0.5 % as standard and adjustable to the project. Lines are normally split into 4 m sections for safe transport, while single elements up to 6 m can be produced. Sections join with mounting flanges and an EPDM gasket, or can be welded on site. Levelling screws and anchors make it easier to set the channel correctly before concrete is poured.
Channel edges can be left open, filled with epoxy resin, or reinforced with stainless flat bar for areas with heavy traffic. Bottom profiles include flat, V-shaped and rounded versions, and slot, mini and maxi slot channels are available where a narrow opening is preferred.
Stainless top slots, 1 to 3 mm thick, fit channels made of polymer, concrete, GRP or plastic and can be specified for load classes A15, B125 and C250. The narrow, heel-safe slot suits facades, pedestrian zones, car parks and landscaped public spaces. For professional kitchens in hotels, restaurants, schools and hospitals, ATT Kitchen channels combine anti-slip gratings tested to DIN 51130 with a buffer for large discharges such as boiling pans. For showers, bathroom channels come in standard lengths from 700 to 1000 mm, and the BWD wall drain hides the outlet at the wall line.
Manhole and access covers
Square stainless manhole covers are offered from 300 x 300 mm up to 1000 x 1000 mm clear opening in classes A15, B125, C250 and D400. Round covers from D600 to D1000 can be filled with flooring or supplied with checker plate, and the KA-Light series has two seals for odour-tight closure. Multi-part access covers, gas lifters, insulation and ventilation options complete the line. Rodding eyes for pipes from DN110 have smooth or checker plate lids sealed against water ingress.
Applications for ATT InoxDrain
The main market for ATT InoxDrain is food processing, where drains are exposed to fats, blood, brine and aggressive cleaning agents. Typical projects include:
- dairies, breweries, bottling plants and abattoirs;
- chemical and pharmaceutical plants, sewage plants and pumping stations;
- commercial kitchens, hospitals and catering facilities;
- public bathrooms, swimming pools and terraces.
The company also makes protective elements for the same environments: stainless bollards and barriers, hygienic kerbs between floor and wall, expansion joints and 2 to 3 mm buffering tiles for loading ramps and production halls. Platforms, steps and handrails are produced to EN ISO 14122. In food plants, drainage usually works together with pre-treatment, for example grease separators downstream of the kitchen or process line.
Standards, hygiene and quality
The manufacturer states that its point drainage meets PN-EN 1253 and its linear drainage meets PN-EN 1433, and the products are CE marked. ATT InoxDrain design follows hygiene rules for food machinery, namely EN 1672-2 and EN ISO 14159, and the hygienic safety of the products is confirmed by a certificate from the Polish hygiene institute.
Further quality points from the official sources:
- membership of EHEDG since 2016, and regional representation of EHEDG for Poland since 2022;
- conformity with EN 1090-1 and EN 1090-2 for steel structures;
- welding supervision to the EN ISO 3834 series, implemented with TÜV Rheinland;
- pickling and passivation of kitchen products before dispatch.
For specifiers, these points matter because a hygienic drain is judged on its radii, weld quality and cleanability as much as on its flow rate. ATT InoxDrain details such as rounded bottoms, continuous welds and hidden flat bars under gratings are aimed precisely at that.
Why buy ATT InoxDrain through Vesmaco
