Galvanizing is a commonly used anti-corrosion technology in modern industrial society. because of its high performance-to-price ratio

Galvanizing is a commonly used anti-corrosion technology in modern industrial society. because of its high performance-to-price ratio, galvanizing anti-corrosion treatment is needed when the metal wire slot is laid in the building with corrosive gas.
There are many standards for bridges, some are suitable for outdoor bridges and some are suitable for indoor bridges.
The common specifications of metal wire slot are 100*50mm, 200*100mm, 300*100mm, 400*100mm and so on. The larger the specification of metal wire slot is, the higher the price is.
For more details, please refer to the following: 1. When the metal wire slot is laid, the width of the bridge is less than 400mm, and the angle steel of 30mm*30mm*3mm, Φ 10 threaded suspender and supporting expansion bolts are selected to make the hanger.
When laying supports and hangers for metal wire grooves, you should use hanging wires or elastic wires to find straight, and use a horizontal ruler to level them, so as to ensure that they can be horizontal and vertical after installation.
2. Galvanizing technology galvanizing technology is divided into electrogalvanizing and hot-dip galvanizing.
The galvanized coating of electrogalvanized zinc has good ductility and will not fall off easily when carrying out various cutting bends and transportation impacts.
The adhesion of electroplating galvanization itself is also very good, will not easily peel, protruding.
The life of the hot-dip galvanized zinc layer in a specific environment mainly depends on the thickness of the zinc layer and the corrosion strength of the environment. The thickness of the zinc layer depends on the thickness of iron and steel. The thicker the iron is, the thicker the zinc layer is.
3. The national standard of cable tray includes "JB/T 10216-2000 cable tray for electronically controlled distribution" (abbreviated as 2000 national standard) and "JB/T 10216-2013 cable tray for electronically controlled distribution" (abbreviated as 2013 national standard).
The 2000 national standard is applicable to the cable bridges of indoor and outdoor industrial and civil buildings, high and low voltage power transmission and distribution projects.
The relevant national standards cited are GB/T 4208-1993 shell protection grade (IP code).
4. Bridge specifications the commonly used small specifications of cable bridges are 50*25mm, 60*25mm, 60*40mm, 60*50mm, 80*40mm, 80*50mm, 80*60mm, 100*50mm, 100*60mm, 100*80mm and so on.
The main material of cable bridge hanger is divided into suspender and cross pole.
Suspender materials are through wire, angle steel, C steel, channel steel.
The materials of the cross load are suspension frame (only for bridge frames of less than 100-50), angle steel, channel steel and C-section steel.
5. The price of cable tray with the same structure and different specifications, for example, cable tray 100*100mm is more expensive than 100*50mm, and 100*100mm is cheaper than 200*100mm.
For cable trays of the same specification and different materials, the price of galvanized cable tray is higher than that of aluminum alloy cable tray, and the price of FRP cable tray is cheaper than that of galvanized cable tray.
