2-meter cable trays are commonly made from galvanized steel, stainless steel, aluminum, or composite materials, each offering specific strength, corrosion resistance, and suitability for different environments.

Common Materials

Galvanized Steel: A widely used option for 2-meter cable trays, galvanized steel provides excellent corrosion protection through a zinc coating that forms a protective patina over time. It is durable, cost-effective, and suitable for indoor and outdoor installations, including industrial and commercial environments. For example, a 200 x 60 mm galvanized cable tray with 0.90 mm thickness is available in 2-meter lengths, meeting CE certification and fire resistance standards (DIN 4102-12:1998, E90) . Stainless Steel: Stainless steel trays, often made from AISI 316L, offer superior corrosion resistance, especially in chloride-rich or highly corrosive environments. The addition of chromium and molybdenum enhances durability and prevents pitting and stress corrosion cracking, making them ideal for chemical plants, coastal areas, or outdoor installations . Aluminum: Aluminum cable trays are lightweight, corrosion-resistant, and easy to handle. The natural oxide layer protects against atmospheric corrosion, and aluminum alloys are selected for mechanical strength and hardness. These trays are suitable for environments where weight reduction is important, such as rooftops or suspended installations . Composite Materials: Pultruded trays made from polyester resin or vinyl ester provide high resistance to corrosion while maintaining a favorable strength-to-weight ratio. These are often used in highly corrosive or chemical environments where metal trays may degrade over time .

Considerations for 2-Meter Cable Trays

• Load Capacity: Material thickness and tray type (ladder, perforated, or channel) affect the maximum cable load and span between supports .
• Environmental Resistance: Choose galvanized steel for general use, stainless steel for corrosive environments, aluminum for lightweight applications, and composites for chemical resistance .
• Standards Compliance: Ensure trays meet relevant certifications such as CE marking, ISO 14001, ISO 45001, and fire resistance ratings .
• Installation: 2-meter trays are typically connected using screws and nuts (e.g., M8x15) and can be suspended from ceilings or mounted on walls . By selecting the appropriate material, a 2-meter cable tray can provide long-term durability, safety, and compliance for your electrical or data cabling installations.
