Cable trays are manufactured in straight sections to simplify transport, installation, and structural design. The most common standard length for a single tray section is 3 meters (approximately 10 feet), which balances ease of handling with installation efficiency . Some manufacturers also offer 2-meter, 4-meter, or 6-meter sections for specific project requirements or to reduce the number of joints .
