Galvanized cable trays can be safely cut at right angles using band saws, circular saws, or angle grinders, with proper PPE and burr removal.

Recommended Tools and Techniques

• Band Saw: Ideal for low-height, thin metal trays. Provides accurate cuts with minimal noise and debris. Cordless models like the Hilti SB 4-A22 offer a cutting capacity of 63.5 mm and are easy to handle on-site .
• Circular Saw: Suitable for light channels and cable trays. Models with chip collectors and blade guards, such as the Hilti SCM 22-A, improve safety and precision .
• Angle Grinder: Offers flexibility for cutting in tight spaces but produces more splatter and requires careful handling with both hands to avoid injury .
• Avoid Cutting Torches: Using torches is not recommended as it can damage the galvanized coating and weaken the material .

Safety Precautions

• Always wear Kevlar gloves, eye protection, headgear, and appropriate footwear when handling and cutting trays .
• Protect surrounding materials from sparks and overheating during cutting .
• Remove any burrs after cutting to prevent injuries and ensure proper fitting of tray sections .

Best Practices for Right-Angle Cuts

• Measure and mark the cut line carefully to maintain a precise 90-degree angle.
• Use a clamp or guide to stabilize the tray during cutting for accuracy.
• After cutting, deburr edges using a file or grinder to smooth sharp edges and maintain structural integrity .
• For modular systems, ensure that cut ends align with bolt-together fittings or splice plates to maintain load-bearing capacity .

By following these guidelines, galvanized cable trays can be cut accurately at right angles while maintaining safety and the integrity of the tray system.
