wholesale Tray Cable Tray Product Description: Zhenjiang Anhua Electric Co., Ltd. is the core enterprise of Anhua group. It mainly produces a series of products, such as junction cable tray, bus duct, high and low voltage switchgear, comprehensive support and hanger, ah anti vibration and anti-skid cogging (embedded channel). The factory covers an area of 36000 square meters and a construction area of 24000 square meters. There are about 568 employees, including 145 professional scientific and technological personnel. The products are widely used in domestic metallurgy, high-speed railway, expressway, urban rail transit, petroleum, chemical industry, nuclear power, electric power, tunnel, urban pipe gallery and other fields, and are exported to Japan, the United States, the Middle East, Austria and other countries and regions. Tray is a tray with many waist shaped holes at the bottom to facilitate heat dissipation; The bottom of the ladder is like a staircase, and there is a baffle on the side. The ladder is used in places with a lot of dust, which will not accumulate dust. Trough and tray are different at the bottom, with and without holes. The tray type is not good for heat dissipation. Hot dip galvanizing, also known as "hot dip galvanizing", is also known as "cold galvanizing" or "electro galvanizing". Difference: 1. Compared with cold galvanizing, the zinc layer of hot galvanizing has better corrosion resistance due to zinc and f ferroalloy layer. The zinc layer of electro galvanizing is thinner and the corrosion resistance is worse. 2. The production process is different. Process of cold galvanizing: put the steel surface after chemical cleaning into the electroplating solution, which contains zinc oxide. One pole of direct current is connected to the steel and the other pole is connected to the zinc plate placed in the electroplating solution. After power on, the zinc is replaced to the steel surface in molecular state. If the brightener is added for passivation, it reflects the color cloud like bright coating. Hot dip galvanizing process: immerse steel parts or castings in molten zinc to form zinc ferroalloy or zinc and zinc ferroalloy coating on their surface.wholesale Tray Cable Tray website:http://www.acecabletrays.com/cable-tray/tray-cable-tray/
