Hot Dip Galvanized Steel Grating for Industrial Drainage

Hot-Dip Galvanized Steel Drainage Grating High Flow Capacity Industrial Pavements

Product Introduction

Data Sheet

Production Process

1. Heavy-Duty Fabrication:
   • Flat bars are plasma-cut and deburred for precision slot spacing (25mm ±1mm).
   • Cross bars welded at 100mm intervals using robotic welding (weld strength ≥5kN per joint).
2. Galvanization for Harsh Environments:
   • Dual-layer process: First zinc immersion for corrosion protection, then epoxy primer for chemical resistance (optional for industrial zones).
3. Debris Retention Design:
   • Slots angled at 15° to trap larger debris (≥30mm) while allowing water to pass through, reducing maintenance frequency.
4. Quality Assurance:
   • Load testing with 20-ton hydraulic press to simulate truck traffic.
   • Flow rate measured in controlled rainfall simulations

Key Advantages

1. Industrial-Grade Drainage Performance

• Rapid Water Removal: 83% open area prevents water pooling, critical for safety in wet industrial environments.
• Debris Management: Angled slots reduce clogging, cutting maintenance costs by 50% compared to traditional grates.

2. Unmatched Durability

• 20+ Year Warranty: Galvanized coating withstands heavy machinery, oil spills, and saltwater.
• Impact Resistance: Survives 10-ton dropped pallet tests without deformation, meeting NCHRP 350 standards for highway applications.

3. Installation & Cost Efficiency

• Modular Design: Lightweight panels (32kg/m²) lift by hand, speeding installation by 40% vs. concrete drains.
• Lower Lifecycle Cost: 40% cheaper than cast iron grates over 20 years, with zero replacement costs for rust damage.

4. Environmental Compliance

• Chemical Resistance: Suitable for capturing oil/chemical spills in compliance with EPA stormwater regulations.

Applications

• Industrial Pavements: Truck yards, aircraft hangars, and factory driveways.
• Infrastructure Drainage: Highway medians, bridge decks, and tunnel entrances.
• Wastewater Facilities: Treatment plant walkways, sump covers, and drainage channels.
• Commercial Sites: Parking garages, fuel station aprons, and outdoor dining areas prone to flooding.
