Galvanized Perforated Cable Tray
Product Specification
| High Light | perforated cable tray gi ，gi cable tray with warranty ，steel cable tray perforated | ||
A premium-grade, corrosion-resistant Galvanised Iron (GI) perforated cable tray designed for efficient cable routing, optimal heat dissipation, and heavy-duty structural support.
| Parameter Category | Common Specifications & Range | Engineering & Application Notes |
| Width | 50 mm to 1000 mm (Standard: 100, 150, 200, 300, 450, 600 mm) | Selected based on the total cross-sectional cable volume and fill-capacity rules. |
| Height / Depth | 25 mm, 50 mm, 75 mm, 100 mm, 150 mm | Determines the structural load-bearing capacity and allowed cable stacking depth. |
| Standard Length | 2.4 meters, 2.5 meters, 3.0 meters | 3-meter lengths are widely preferred to reduce the number of splice plates by 20%. |
| Material Thickness | 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm | Matched according to the specified load class requirements (Light, Medium, or Heavy Duty). |
| Pre-Galvanized Finish | Zinc Coating: 10 to 20 microns (Z120 - Z275 coating mass) | Stamped directly from pre-coated steel coils. Provides a smooth, bright finish ideal for indoor environments. |
| Hot-Dip Galvanized Finish | Zinc Coating: 45 to 85 microns (BS EN ISO 1461) | Fabricated from black steel then completely submerged in molten zinc. Essential for outdoor or corrosive settings. |
| Perforation Airflow | 30% to 42% open ventilation area | Meets international electrical codes (e.g., NEC) regarding free-air rating for power cable heat dissipation. |
| Slot Configuration | Alternating oblong slots (e.g., 7×25 mm or 9×30 mm) | Designed for flexible alignment of cable ties, heavy-duty cleats, and copper earth-bonding links. |
| Flange Profile | Straight Flange or Inside Return Flange (Safety Edge) | Return flanges increase overall load rigidity by up to 30% and prevent raw metal edges from cutting cable jackets. |
| Safe Working Load (SWL) | 40 kg/m to over 250 kg/m | Highly dependent on the chosen support span distance and the thickness of the GI sheet. |
| Recommended Support Span | 1.2 meters to 2.4 meters | Standard spacing is 1.5m. Spacing exceeding 2.0m requires heavier gauges or reinforced side channels. |
| Manufacturing Standard | IEC 61537 / BS EN 61537 | The core global benchmark governing cable tray loading, deflection limits, and electrical continuity. |
| Steel Material Standard | BS EN 10143 / BS EN 10346 | Guarantees chemical and mechanical consistency of the underlying base metal and zinc adhesion. |
| Load Testing Standard | NEMA VE 1 / CSA C22.2 No. 126.1 | Standardized physical test procedures utilized to verify the declared safe working load margins. |
