Fireproofing Construction Process for Cable Trays

Home / Fireproofing Construction Process for Cable Trays

Cable trays and busways at floor level or at slab penetrations shall have a waterstop no less than 50 mm in height. At slab penetrations, provide 20–30 mm of firestopping and install a fire-support plate at the top. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. Route Planning and Layout Principles Coordinate with Building Structure: Cable tray routing should align with architectural design, avoiding unnecessary. · Uneven Surface of Fireproof Mortar: If the fireproof mortar is not applied evenly, it can create a visually unappealing finish while also compromising the sealing's integrity.
