There are many national standards for cable tray, and the technical specification of T/CECS 31-2017 steel cable tray is the latest standard, in which different galvanizing processes and corresponding zinc layer thickness are clearly defined.
The relevant knowledge points are as follows: 1. National Standard 2000 is suitable for cable bridges of industrial and civil buildings, indoor and outdoor, high and low voltage power transmission and distribution projects.
The relevant national standards cited are GB/T 4208-1993 shell protection grade (IP code).
The national standard 2000 was issued on November 29th and implemented on December 1st, 2000.The release date of the national standard 2013 is December 31, 2013, and the formal implementation date is July 1st, 2014.
2. When the width of the molded enhanced ladder frame in the thickness standard is greater than 150mm and less than or equal to 400mm, the thickness of the side plate should be at least 1.2mm, the thickness of the rung should not be less than 1.2mm, and the thickness of the cover plate should not be less than 0.6mm.
According to the standard of 2013 bridge, the width of tray and ladder is greater than 500mm and less than or equal to 800mm, if it is steel, the thickness of bridge should be 2.0mm, if it is aluminum alloy, the thickness of bridge should be at least 2.2mm, if it is made of fiberglass, the minimum thickness of bridge should be 4.5mm.
3. The service conditions and service life of galvanized metal parts are closely related to the thickness of electroplated galvanization. the more stringent the use conditions are, the longer the service life requirements are, the thicker the required zinc coating thickness is.
Hot-dip galvanizing has strong advantages in the bonding strength between zinc layer and substrate, compactness, durability, maintenance-free and economy. At present, hot-dip galvanizing products mainly include steel plate, steel strip, steel wire, steel pipe and so on.
4. Zinc layer thickness requirements for zinc plating zinc layer thickness > = 12um, suitable for bridge protection in indoor general corrosion environment.
Thickness requirement of hot-dip galvanized coating > = 65um, suitable for bridge protection in outdoor strong corrosion environment.
