Cable trunking tee, also known as galvanized steel trunking tee or GI trunking tee junction, is specially designed and engineered for creating three-way branch connections in cable trunking systems whilst providing complete cable protection and easy access. As the reliable cable trunking manufacturer, Lanye brand custom cable trunking tee is available in various configurations, materials, sizes and forms to suit the location and requirements of the installation. Our cable trunking tees can be used in almost any places including homes, commercial and industrial construction, supermarkets, hotels, hospitals, power plants, underground construction and high rise buildings, etc.
A cable trunking tee is a pre-fabricated fitting used to create a three-way junction in a cable trunking system, allowing cables to branch off in a perpendicular direction from the main trunking run. Unlike cable tray tees which have open or perforated bottoms, cable trunking tees feature a fully enclosed solid bottom and removable cover, providing complete protection for internal cables against dust, water ingress, and physical damage.
Cable trunking tees are commonly fabricated using carbon steel grades Q195 or Q235. In the automated pre-galvanizing process, the carbon steel plates are immersed in a “galvanizing bath” containing molten zinc for a brief period. After being withdrawn from the bath, excess zinc is stripped away, leaving a relatively thin yet effective zinc coating on the steel surface. The cable trunking tee is then manufactured using pre-galvanized steel through standard procedures such as punching, bending, and forming, carried out by a flexible automatic production line.
Galvanized cable trunking tee exhibits excellent qualities including high strength, a robust design, durability, and resistance to rust. These characteristics make it an ideal choice for cable management, providing support and protection for internal cables against damage, dust, and water ingress. Cable trunking tee is the reliable cable management solution to ensure the longevity and proper functioning of cables, especially in applications where cable protection is a priority.
