The Allproof SL Series is a discreet yet high-capacity stainless steel slot drain designed for demanding commercial environments such as commercial kitchens, food and beverage production facilities, industrial processing areas, and high-traffic public spaces. With only a 20mm linear slot visible at the surface, it provides a sleek, minimalist aesthetic while delivering robust performance and efficient water removal.

Fabricated from 304 stainless steel as standard (or 316 stainless steel upon request), the SL Series is engineered for durability, corrosion resistance, and long-term reliability. The 15mm epoxy-filled safety edges create a safe, smooth transition across flooring surfaces, meeting workplace safety requirements in busy operational spaces.

The SL Series slot drain is modular, with channel sections supplied in 1m or 2m lengths connected by bolted unions and gaskets for simplified transport, installation, and custom layout design. Each channel has a built-in fall to direct water towards a 200mm clear opening sump, which can be configured for centre, end, or corner positions.

Hydraulic efficiency and system adaptability make the SL Series ideal for custom layouts, including applications where hygiene and safety are critical. Each system can be tailored to suit the unique needs of your facility, from restaurants to food production plants, commercial food courts, or even heavy-duty processing environments such as bottling plants and secure institutional kitchens.

Allproof recommends engaging early in the design stage to ensure your drainage system is tailored to your exact project requirements, avoiding costly remedial works post-installation.
