How to prevent stainless steel cable trays from shrinking due to cold
The cable tray needs to be anchored at the support closest to the midpoint between the expansion joints with hold down clamps and secured by expansion guides at all other support locations. The expansion guides allow the cable tray to slide back and forth as it contracts and. General guidelines on the proper cable tray material to specify when dealing with low temperatures are listed below. As temperature decreases, low-carbon steel products will loose ductility slowly until a certain point where the ductility rapidly decreases by over 50% within a very small. Metal becomes bigger when hot and smaller when cold. Cable trays have no space to flex, and may bend or break bolts.
