Pre galvanised cable trunking, also known as galvanized steel trunking or gi trunking, is spelcially dsigned and engineered for supporting and managing cables, whilst providing easy access to the cables via a hinge or slide system.

As the reliabel galvanised trunking suppliers,  JLH brand galvernized steel trunking is available in various configurations, materials, sizes and forms to suit the location and requirements of the installation. Our metal cable trunking 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.

1. What Is Pre Galvanised Cable Trunking?

Pre-galvanized cable trunking is 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 After being withdrawn from the bath, excess zinc is stripped away, leaving a relatively thin yet effective zinc coating on the steel surface.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 pre-galvanized cable trunking is then manufactured using pre-galvanized steel cable through standard procedures such as punching, bending, and galvanizing, carried out by a flexible automatic production line.

Galvanized cable trunking 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. In certain cases, it can even be used for cable concealment purposes.

Pre-galvanized steel trunking is the reliable cable tray solution to ensure the longevity and proper functioning of cables. Its ability to withstand various environmental factors, combined with its anti-rust properties, makes it a preferred option for efficient cable organization and safeguarding.
