Slot drainage channel

slopedstainless steelfor public spaces

Overview
INZA SR slotted channels are stainless steel linear drainage systems engineered for controlled evacuation of stormwater and process wastewater in industrial, commercial and urban environments. The modular, watertight design integrates an omega profile with a V-shaped bottom and a 20 mm slot to accelerate flow and limit sediment accumulation.

Main characteristics

• Material: AISI 304 or AISI 316L stainless steel.
• Slot opening: 20 mm.
• Channel geometry: omega-type section with V-shaped (narrowing) bottom to increase flow velocity and support self-cleaning behaviour.
• Modular system: straight sections, elbows, corners, inspection chambers and siphonic outlets joined by stainless steel plates and screws with EPDM gaskets for watertight connections.
• Straight section length: up to 3 m per section; continuous lines with built-in slope can reach up to 24 m between drains.
• Built-in slope: typically from 0.66% to 2% depending on configuration and length.
• Outlet options: welded direct outlets or siphonic stainless steel floor drains with removable siphons and solids collection baskets; vertical and horizontal outlet configurations available.
• Anchorage & reinforcement: steel anchors for concrete fixing; lateral wing reinforcement with NBR profile or square stainless steel profile to prevent deformation; optional threaded leveling feet.
• Hygiene & durability: stainless steel construction resists corrosion, is easy to clean and meets hygiene requirements for food, pharmaceutical and other sanitary environments.

Applications

• Industrial facilities (processing areas, production halls) requiring regular cleaning and strict hygiene control.
• Wineries, oil mills, meat processing and bottling plants.
• Laboratories, hospitals and other sanitary environments.
• Commercial and urban pavements where discreet linear drainage is needed.
• Areas with industrial traffic where minimal wheel contact surface is required.

Advantages

• Modular, adaptable solution for customised layouts.
• Watertight bolted connections minimise leakage risk.
• High hydraulic efficiency due to built-in slope and V-shaped bottom; effective solids conveyance and reduced maintenance.
• Mechanical resistance suitable for industrial traffic with limited wheel contact area.
• Facilitates floor design by reducing the need for complex local falls.
• No moving parts; simplified installation and maintenance.
• Discreet, minimal appearance for integration into decorative or industrial surfaces.
