Pre-galvanised, hot-dip galvanised or powder-coated: how environment and budget decide.
The finish of a cable tray decides how long it lasts. Pre-galvanised steel suits dry indoor areas. Hot-dip galvanising gives a thicker zinc layer for outdoor, coastal and industrial sites. Powder coating adds colour coding and extra protection where trays are visible.
Our engineers recommend a finish for each zone of a project so budget goes where protection is needed.
