Thickness standard aluminum alloy cable tray 2013 industry standard stipulates that when the width of the bridge is greater than 800mm, the thickness of the bridge plate should be 3. 0mm, the thickness of the connecting plate of the bridge should be at least. Cable tray (or cable ladder) systems are a popular alternative to electrical conduit systems, as they have an outstanding record for dependable service, design flexibility and cost savings in commercial and industrial applications. A properly designed and installed cable tray system will provide. ies aluminum alloys (Aluminum Association designation) to manufacture cable tray. The alloys are selected for their mechanical properties, such as strength and hardness, as well as for their resis ance to corrosion, particularly stress corrosion, cracking, and pitting co anufactured using a. The commonly used specifications are 100*50mm, 100*100mm, etc., and the commonly used thickness are 1. The following is a description of the relevant content for your reference. Aluminum alloy bridge tray the support and hanger of aluminum alloy cable tray can be made of. Below is a quick overview of the four main thickness ranges, each linking to detailed charts and applications: Common tempers: O, H14, H24, H32 (ideal for bending, anodizing, perforation) Typical alloys: 1100, 3003, 5052, 5754, 6061 The 2–6 mm aluminum plate range covers some of the most frequently.
