Stainless Steel Drainage Channels

B&K GROUP stainless steel drainage channels for the food industry are engineered for maximum wastewater removal efficiency in industrial environments. These solutions deliver reliable performance under heavy-duty conditions where hygiene, durability, and resistance to chemical and mechanical factors are critical.

They form an essential part of the technical infrastructure in production facilities requiring effective and safe removal of process water and contaminants from floor surfaces.

Features and Applications – Drainage Channels

Compact drainage channels are a premium solution for efficient water and contaminant removal in demanding industrial settings. Fully made of stainless steel, they provide durability, hygiene, and resistance to corrosion and aggressive chemicals used in production and cleaning processes.

B&K GROUP stainless steel channel drains are used in the food industry, breweries, dairies, and other industrial facilities with high sanitary standards. The system works as linear drainage and as a collection trough in production and wash-down zones.

Construction and Configuration Options

Drainage channels are available as single straight sections or as a modular system that can be joined with flanged gaskets or site-welded using special connectors. This allows flexible adaptation to site conditions.

At the lowest point of the channel, a drain outlet (German: Bodenablauf) – single- or two-part – ensures effective removal of liquids and debris.

B&K GROUP drainage systems offer extensive configuration options. Installation length is virtually unlimited, with standard widths from 100 mm to 1000 mm. The system can include corners, transitions, and custom elements for tailored drainage solutions.

Compatibility and Installation

The BOX-type linear drain is designed for compatibility with various industrial floors, including concrete, resin, and industrial tiles – square and hexagonal.

The system supports easy installation in both new builds and refurbishments without major changes to existing infrastructure.

Hygiene and System Performance

Precision manufacturing and high-grade stainless steel ensure B&K GROUP drainage channels meet strict hygiene standards required in food and pharmaceutical industries. The smooth internal surface minimizes residue buildup and microbial growth, simplifying cleaning.

The design is optimized for easy cleaning and integration with CIP systems, maintaining high hygiene while reducing operating costs and downtime.

Additional Options and Safety

Drainage channels can be customized to project requirements in dimensions and technical parameters. Various grating types, covers, and anti-slip elements are available to enhance safety in production zones.

Drainage systems are designed with appropriate falls to ensure efficient liquid removal even under intensive use.

Frequently asked questions

What is the difference between drainage channels and linear drains?

Drainage channels are the general category of linear drainage systems — covering both open-grate channels (classic) and narrow-slot versions. Linear is a synonym — they drain water linearly along the entire length. Grating choice depends on the zone: open grates for high-flow areas (wash-down zones), slot grates for forklift traffic areas.

What flow rate class (Q l/s) do I need for my hall?

Rough calculation: Q = A × i × ψ, where A — drained area in m², i — water intensity (0.015-0.030 l/s/m² indoors), ψ — runoff coefficient (0.9 for resin, 1.0 for concrete). For a 500 m² hall Q ≈ 7-15 l/s. For wet zones (food industry with CIP cleaning) multiply by 2-3×. We advise free selection after receiving hall layout with wet zones marked.

What falls do you design for drainage channels?

Standard fall 0.5-1.0% toward the outlet. For channels longer than 10 m we recommend 1.0-1.5%. Greater fall = faster drainage, less ponding, no deposits. Factory-fitted fall channels cost more but eliminate installation errors. Without fall, water stagnates → bacteria → odor → short service life.

Do the drainage channels comply with DIN/EN 1433?

Yes — all our channels are manufactured to EN 1433 (European standard for linear drainage systems). Load classes A15, B125, C250, D400, E600, F900. Material and sheet thickness are selected according to class. On request we issue a declaration of conformity — often required for project handover documentation.

What drainage channel dimensions are available?

Standard widths (external): 100, 150, 200, 250, 300 mm. Depths: 60-200 mm depending on load class. Segment lengths: 1000, 2000, 3000, 5000 mm — joined with overlapping rubber seal or site-welded. Non-standard sizes (e.g. 400 mm width for very high flow) — made to order.

Which grates are compatible with your drainage channels?

Full range of grates: slot (for traffic zones), perforated (flow + aesthetics), orthogonal mesh (classic, lowest cost), ribbed (highest mechanical strength), bridge (very high flow). All grates anti-slip (R10-R13). Grate material: V2A standard, V4A for aggressive media. We advise selection according to application zone.

What is a collector drainage channel?

A collector (main) drainage channel collects wastewater from multiple drains and linear channels and conveys it jointly to the sewer. Used in large halls with high flow rates; manufactured in V2A/V4A stainless steel.
