As an important supporting component of the tray bridge, the bracket arm is carefully made of high-strength steel, aluminum alloy or stainless steel SS304/SS316L. The surface can be treated by electro-galvanizing, hot-dip galvanizing, spraying and other processes to meet the needs of different environments. The bracket arm has a reasonable structural design and is easy and quick to install. It can easily fix the tray bridge to ensure the stability and safety of the cable line. It is particularly suitable for industrial fields such as power plant, marine, mining, etc. Its strong bearing capacity and excellent corrosion resistance make the bracket arm a key component to improve the overall performance of the cable management system.types of brackets,sports tournament brackets.
