  • Use seismic-resistant supports for cable trays and ducts

    Use seismic-resistant supports for cable trays and ducts

    Suspended systems such as piping, equipment and ductwork need seis-mic braces to keep them from swaying during an earthquake. Founded in 2006 as a subsidiary of Çemesan Group, which has been operating in the steel industry for nearly 40 years, Eurotray is. EAE Seismic Support Systems offer rigid solutions for installations that require earthquake protection. What are the types of cable bracing? Seismic bracing is categorized as cable bracing or rigid bracing. Cable bracing works in tension, so it requires two opposing brace assemblies at each brace location. Our strong legacy includes OSHPD OPA and OPM approvals, Structural Engineer approvals, and compliance with Internation-al Building. The Code for Seismic Design of Mechanical and Electrical Systems in Buildings formalized seismic support systems as essential safeguards. Braces are typi-cally installed.

  • Drilling holes in stainless steel cable trays and burning drill bits

    Drilling holes in stainless steel cable trays and burning drill bits

    Drilling stainless steel needs to be done with sharp bits, low RPM, higher cutting pressure (feed), and lots of lube/coolant. High RPM will lead to immediate burned-out drill bits. Get the wrong bits, go too fast or forget the coolant, and you'll find yourself fighting work hardening, broken bits or ruined holes. This article. Drilling through stainless steel isn't a job for just any tool. It's a tough, heat-resistant material that punishes cheap bits and poor technique. Selecting the correct drill bit is the most important factor for successfully machining stainless steel.

  • How to mark lines when drilling holes for cable trays

    How to mark lines when drilling holes for cable trays

    Snap Lines: Use a chalk line or laser level to mark the path on the ceiling or wall. Mark Support Points: Mark the spots where supports will be installed. Standard intervals are usually every 1. Measuring and marking: Accurate measurement and marking techniques for cable trays. Calculate horizontal, vertical, or compound cable tray offsets based on bend angle, offset distance, and available installation. Watch how a professional fabricator perfectly marks, measures, and cuts a cable tray using a hand grinder with complete accuracy. I have used a marker with a speed square on projects, but that is a rough method.
