Product Overview

The Galvanized Perforated Cable Tray is a versatile, lightweight, and cost‑effective solution for indoor electrical cable management. The perforated bottom provides excellent ventilation while allowing small cables to be easily supported and routed. Hot‑dip galvanized (HDG) or electro‑galvanized finish ensures reliable corrosion resistance for general industrial and commercial applications.

Perforated design – ventilation + small cable support
Galvanized finish – HDG (≥65µm) or electro‑galvanized (Z12‑Z25)
Easy installation – lightweight, pre‑punched splice holes
Compliant with NEMA VE 1 / IEC 61537

Load Class & Span Guide (per NEMA VE 1 / IEEE 1222)

Load Class	Typical Thickness (Ga/mm)	Max Safe Span (m)	Load Capacity (kg/m)	Typical Applications
Light Duty (LD)	20 Ga (0.8 – 1.0 mm)	2.0 – 2.5	50 – 80	Office cabling, control cables, small data lines
Medium Duty (MD)	16 Ga (1.2 – 1.5 mm)	2.5 – 3.0	80 – 120	Industrial power & control, equipment rooms
Heavy Duty (HD)	14 Ga (1.5 – 2.0 mm)	3.0 – 3.5	120 – 180	Heavy power cables, dense fills
Extra Heavy Duty (EHD)	12 Ga (2.0 – 2.5 mm)	3.5 – 4.0	180 – 250	Substations, power plants, long spans

Load capacity includes both cable weight and a safety factor. For exact loads, consult load tables.

Surface Finish Comparison

Finish Type	Coating Thickness	Corrosion Resistance (Salt Spray)	Appearance	Best Environment
Electro‑galvanized (Z12‑Z25)	12 – 25 µm	100 – 200 hours	Bright, smooth	Indoor, dry, mild climate
Hot‑dip galvanized (HDG)	≥65 µm (ASTM A123)	500 – 1000+ hours	Matte, grey	Industrial, outdoor, moderate humidity
Pre‑galvanized (mill galvanized)	20 – 30 µm	200 – 300 hours	Spangled	Warehouse, light industrial
HDG + Passivation	≥65 µm + chromate	800+ hours	Slightly tinted	Coastal / high humidity indoor

Recommendation: Use HDG for any outdoor or mildly corrosive indoor environment. Electro‑galvanized is sufficient for clean, dry indoor areas such as offices or control rooms.

Key Features & Benefits

Feature	Benefit
Perforated bottom	Allows air circulation, heat dissipation, and small cable branching
Pre‑punched splice holes	Faster assembly, no on‑site drilling
Easy cable tie‑down	Perforations accept cable ties at any point
Lower weight	15‑25% lighter than solid bottom trays – reduced shipping & labor cost
Versatile	Use with or without covers; suitable for ladders or troughs
Zinc coating protection	Prevents red rust; life expectancy 10‑25 years depending on environment

Available Accessories

Accessory	Description
Horizontal Elbow (90°/45°)	Pre‑fabricated perforated bends
Inside / Outside Tee	For branching runs
Reducer	Step‑down width transition
Riser / Vertical Bend	For floor‑to‑floor routing
Coupler / Splice Plate	Connects two tray sections
Cable Tray Cover	Solid or slotted – dust protection
