Gray Galvanized Cable Tray Models

Gray galvanized cable trays are available in pre-galvanized (PG) and hot-dip galvanized (HDG) steel, with multiple models including ladder, ventilated, and solid-bottom trays.

Types of Gray Galvanized Cable Trays

1. Ladder Cable Trays
   • Feature side rails with rungs for cable support.
   • Ideal for heavy-duty applications and long cable runs.
   • Available in pre-galvanized (PG) for indoor dry environments or hot-dip galvanized (HDG) for outdoor or high-moisture areas .
2. Ventilated (Perforated) Cable Trays
   • Solid bottom with perforations for airflow and heat dissipation.
   • Suitable for medium-weight cables in offices or industrial settings.
   • Coating options: PG (12–20 microns) or HDG (65–85 microns) for corrosion resistance .
3. Solid-Bottom Cable Trays
   • Continuous flat bottom for maximum cable protection.
   • Recommended for sensitive or low-voltage cables.
   • Typically available in HDG for long-term durability in harsh environments .
4. Wire Mesh or Basket Trays
   • Lightweight, flexible trays for routing small cables.
   • Usually pre-galvanized for indoor use; HDG available for outdoor applications .
