Unlike residential drains with limited capacity (≤5L/s), it features a large-diameter sump (φ100-200mm) and anti-clogging grille, supporting drainage rates up to 30L/s and handling solid debris up to 20mm. It complies with EN 1253 standards for load-bearing (up to D400 class, 400kN) and is indispensable in factories, warehouses, and food processing plants.
Heavy-Duty Load-Bearing: Available in load classes B125 (125kN) to D400 (400kN), with 316L stainless steel variants supporting forklift traffic (≤5t). The grille’s reinforced rib structure (thickness 5-8mm) prevents deformation under 200kN point load, maintaining integrity for 10+ years.
Anti-Clogging Design: Grille opening size customizable from 5mm to 25mm with tapered holes (15° incline) that reduce debris accumulation by 70%. A removable filter basket (mesh size 2mm) captures solids, preventing pipe blockages—cleaning frequency reduced by 60% vs. standard drains.
Corrosion Resistance: 316L stainless steel variants resist chemical spills (pH 2-13) with corrosion rate < 0.01mm/year; epoxy-coated ductile iron offers cost-effective protection (corrosion rate < 0.03mm/year) for general industrial use. Passes 1000-hour salt spray test (ASTM B117) with no red rust.
Easy Installation & Maintenance: Flange or embedded installation options, compatible with concrete and epoxy floors. The sump’s smooth interior (Ra < 0.8μm) allows quick cleaning via high-pressure water (10-15 bar), restoring full capacity in 5 minutes.
Food Processing Plants: Sanitary drainage for meat and dairy facilities. A German dairy used 316L stainless steel drains (10mm grille) for milk processing areas, complying with FDA 21 CFR Part 177 and reducing cleaning time by 4 hours/day. The anti-bacterial coating eliminated 99% of surface bacteria.
Manufacturing Factories: Coolant and wastewater drainage for machine shops. A Chinese automotive plant installed D400-class drains (φ150mm sump) for CNC machine coolant, handling 25L/s flow and preventing coolant pooling—equipment downtime reduced by 30%.
Warehouses & Logistics Centers: Rainwater and spill drainage for loading docks. A US logistics hub adopted 20mm grille drains, removing rainwater at 30L/s and avoiding slip hazards—workers’ compensation claims related to slips dropped by 80%.
Q: Which load class fits forklift traffic?
A: D400 class is mandatory for forklift traffic (≤5t), as it withstands 400kN load. For lighter traffic (pallet jacks, ≤2t), B125 class suffices but has a shorter service life (5 vs. 10 years). Always match load class to maximum vehicle weight.
Q: How to prevent odor from industrial floor drains?
A: Install a water seal (depth ≥ 50mm) or mechanical check valve. For food facilities, use anti-odor grilles with rubber gaskets that seal when dry—this reduces odor emission by 95%. Clean the filter basket weekly to avoid organic buildup.
Q: Can it handle chemical spills (e.g., acids, oils)?
A: Yes, 316L stainless steel drains resist acids (pH 2-13) and oils; avoid epoxy-coated iron for strong acids (pH < 4). For oil spills, add an oil-water separator attachment—captures 98% of oil and prevents sewer contamination.
Q: What’s the minimum floor slope for proper drainage?
A: A slope of 1-2% (10-20mm/m) ensures full drainage without pooling. For high-flow areas (≥20L/s), increase to 2-3%—this reduces drainage time by 40%. Use a laser level to ensure uniform slope during installation.
