Perforated Cable Tray
Perforated steel sheet is a kind of sheet products which is made through a serious of pouncing and stamping processes. Perforated Type Cable Trays are suitable for cables that require both a degree of protection from external damages and ventilation. These are constructed from galvanized iron and mild steel. These are corrosion resistant and highly durable metals are used in designing the stock.
Solid Cable Tray
Generally used for minimal heat generating electrical or telecommunication applications with short to intermediate support spans 5 to 12 feet. The main reason for selecting solid bottom cable tray (with covers) is the concern of EMI/ RFI shielding protection for very sensitive circuits. A solid bottom steel cable tray with steel covers provides a good degree of shielding if there are no breaks or holes in the completed installation.
Ladder Cable Tray
Ladder Cable tray has two side rails connected by rungs. This type of cable tray is effective because the ladder rungs give you easy accessibility to the cables, from the top or bottom. The rungs of the ladder cable trays provide convenient anchors for tying down the cables in the non-horizontal cable tray runs or where the positions of the cables must be maintained in the horizontal cable tray runs.
