Key Factors Influencing Bracket Weight
The weight of a trough-type cable tray bracket is not fixed; much like people of different builds requiring different clothing sizes, bracket weights vary. A 400×150 bracket is typically about 1.5 times heavier than a 200×150 model, depending primarily on three variables:
Material density: Steel is 30% heavier than aluminum alloy.
Structural thickness: There is a 25% difference between 1.5mm and 2.0mm versions.
Reinforcement design: Ribbed structures add 15% to the weight.
Reference Weights for Specific Specifications
Based on actual measurements, approximate values for common types are as follows (with a ±5% margin of error):
400×150 steel bracket: Approx. 2.8–3.2 kg/unit
200×150 steel bracket: Approx. 1.9–2.1 kg/unit
200×150 aluminum alloy bracket: Approx. 1.2–1.4 kg/unit
Practical Tips for Engineering Selection
Selecting brackets is akin to choosing sports gear; it requires balancing strength and flexibility:
Load-bearing priority: Choose the 400 series for areas with heavy equipment; a single bracket can support 60 kg.
Space optimization: Use the 200 series in confined areas to save 30% on installation space.
Corrosion resistance: Aluminum alloy is recommended for humid environments, extending service life by 5 years.
Cost considerations: Use steel for standard cabling to reduce costs by 40%.
