Product Description
High Quality Steel Grating Hot Dipped Galvanized Serrated Outdoor Drain Cover
This high-strength steel grating features hot-dip galvanized coating for superior corrosion resistance, making it ideal for building applications and outdoor drainage systems.
Production Process
Material Preparation
High-quality carbon steel bars are selected and cut to precise lengths according to design specifications, ensuring optimal structural integrity.
Welding Process
Two primary welding methods ensure durable construction:
  • Pressure resistance welding: Efficient automated process creating uniform, high-strength welds
  • Manual arc welding: Used for specialized applications requiring skilled craftsmanship
Pretreatment before Galvanizing
Critical surface preparation steps include:
  • Degreasing to remove contaminants
  • Pickling to eliminate rust and oxidation
  • Thorough rinsing to prepare for galvanization
Hot-Dip Galvanizing Process
The grating is immersed in molten zinc at 450°C, forming a durable zinc-iron alloy protective layer with adjustable thickness for specific requirements.
Quality Inspection
Rigorous testing ensures:
  • Visual inspection for surface defects
  • Measurement of galvanized layer thickness
  • Verification of mechanical properties including load capacity
