Is the cable tray made of stainless steel
Common cable trays are made of galvanized,, aluminum, or glass-fiber reinforced plastic. The material for a given application is chosen based on where it will be used. Galvanized tray may be made of pre-galvanized steel sheet fabricated into tray, or may be hot-dip galvanized after fabrication. When galvanized tray is cut to length in the field, usually the cut surface will be painted with a zinc-rich compound to protect the metal from corrosion.

Cutting a 90-degree right-angle bend in the cable tray
Creating a 90-degree elbow in an electrical cable tray, often called a "fabricated" or "mitered" bend, involves cutting, bending, and fastening a straight section of tray. The most common method involves creating two 45-degree cuts to form a 90-degree angle. (A) = cable tray width (600mm) and B = Size of angle (22°) First you have to find (C) which is found by dividing 90°. Depends on the type of cable tray, you can buy 90° tray fittings or use a speed square with a straight edge and a grinder or skill saw to cut 45° cuts. Do you want a hard 90 or 2 spaced out 45° bends? Need dimension of tray first width x side wall. Perfect for electricians! #electrician #worklife Keywords: cutting cable tray techniques, 90 degree cable tray bend, cable tray installation tips, electrical work cable tray, bending cable trays, cable tray.
