Ladder-Type Cable Tray

ZHONGHENG TENGDA Ladder-Type Cable Tray – High-Strength Ventilated Structure for Professional Cable Routing Solutions

The ZHONGHENG TENGDA ladder-type cable tray is manufactured from high-quality cold-rolled steel, stainless steel, or aluminum alloy using precision roll-forming technology. Its robust yet lightweight structure ensures reliable support for a wide range of cabling needs. The distinctive ladder-style rungs create an open and ventilated design that enhances cable heat dissipation, effectively reducing power losses caused by overheating. This makes it especially suitable for the installation of high-power cables, high- and low-voltage lines, and fiber optic communication cables.

The tray features high-strength trapezoidal side rails combined with evenly spaced horizontal rungs, achieving a single-span load capacity of up to 200 kg/m². Its bending strength is 35% higher than that of conventional channel-type trays, making it ideal for high-load environments such as power plants, petrochemical facilities, and rail transit systems.

Surface treatments including hot-dip galvanizing, powder coating, or anodizing provide outstanding corrosion and rust resistance, allowing the tray to perform reliably in humid, high-temperature, and chemically aggressive environments. Designed for longevity, the product offers a service life of over 20 years.
