For a 2-meter cable tray, typical steel thickness ranges from 1.2 mm for light-duty applications to 2.5 mm or more for heavy-duty or longer-span installations.

Typical Thickness Ranges

• Light-duty trays (e.g., LAN, control wiring in commercial spaces) usually have a thickness of 1.2 mm to 1.6 mm .
• Medium-duty trays for standard power or industrial cables often use 2.0 mm to 3.0 mm .
• Heavy-duty or long-span trays (spans approaching 2–3 meters) require 2.5 mm or thicker to prevent sagging and maintain structural integrity .

Factors Affecting Thickness Selection

1. Span Length: Longer spans need thicker material to avoid deflection. A 2-meter tray is considered a moderate span, so 2.0–2.5 mm is generally recommended for standard industrial loads .
2. Cable Load: Heavier power cables require thicker trays to support cumulative weight safely .
3. Environment: Outdoor or corrosive environments may require thicker trays with protective coatings (galvanized, powder-coated, or stainless steel) for durability .
4. Tray Type: Ladder trays, perforated trays, and wire mesh trays have different structural requirements. Ladder trays often need thicker side rails for load-bearing capacity, while wire mesh trays may use thinner material if supported frequently .

Practical Recommendation

For a 2-meter steel cable tray in a typical industrial or commercial setting, a thickness of 2.0 mm is usually sufficient for medium-duty applications. If the tray will carry heavy power cables or is in a corrosive environment, 2.5 mm or more is advisable to ensure long-term durability and compliance with standards . Choosing the correct thickness ensures load-bearing capacity, minimal sagging, proper cable support, and safety compliance.
