Unistrut cable trays are modular, metal support systems designed for organising and routing cables in commercial settings. They consist of interconnected channels that can be easily mounted to walls, ceilings or floors. These trays accommodate various cable types and sizes, allowing for efficient cable management in complex installations.
What Are the Benefits of Unistrut Cable Trays?
Cable trays provide efficient solutions for cable management and routing. Here is an overview of the key benefits.
- Excellent organisation and accessibility for cables, reducing clutter
- High flexibility, allowing for easy modifications and additions as needs change
- Improved cable cooling by promoting air circulation, which may extend cable life
- Significant reduction in installation time compared to conduit systems
- Cost-effectiveness in the long run because of their durability
How Much Can Unistrut Cable Trays Hold?
Unistrut cable trays are designed to support substantial cable loads. The exact capacity depends on factors like tray size, material and support spacing. Typically, Unistrut cable trays can hold between 22-68 kg per linear foot.
Some heavy-duty models may support up to 90 kg per linear foot. Proper installation and support spacing are essential to maintain the tray's load-bearing capacity.
What Are the Differences in Cable Tray Finishes?
Each finish offers unique properties for corrosion resistance and longevity.
- Pre-galvanised trays are coated with zinc before fabrication. They offer good corrosion resistance for indoor use and are cost-effective. However, cut edges may be exposed to corrosion.
- Stainless steel trays provide superior corrosion resistance and are ideal for harsh environments. They are suitable for food processing and outdoor installations. Stainless steel is more expensive but offers longevity.
- Hot-dip galvanised trays are dipped in molten zinc after fabrication. This process provides excellent corrosion protection, even on cut edges and welds. They are ideal for outdoor and corrosive environments.
What Sizes Are Unistrut Cable Trays Available In?
Unistrut offers a wide range of cable tray sizes to accommodate various project requirements. Standard widths typically range from 150mm to 900mm. Depths can vary from 50mm to 150mm or more.
It is important to consider cable volume, type, and future expansion when selecting cable trays. Need help choosing the right size? Contact our team for guidance on the best options for your project.
