Strut C channels have become one of the most common and most versatile building materials utilized in the construction, electrical and manufacturing industries, and for good reasons like its strength, flexibility and ease of use.
Electrical Cable Trays and Conduits: Strut channel also offers a robust and modular system for supporting cable trays, conduits, and wiring systems in commercial or industrial applications. Thanks to their slotted design, you can make quick modifications or mount electrical parts.
Industrial and Warehouse Racking Systems Storage: Strut C channel provides an excellent medium for building support structures for industrial & warehouse hard shelve racks, pallet racks, and bin racks that are easily adjustable and modular making them perfect for any warehouse or distribution center storage needs.
Pipe & Duct Supports: Strut channel is also widely utilized in plumbing, HVAC ductwork, and piping systems applications in residential, commercial, and industrial settings. Their high carrying capacity makes them long lasting stability and safe.
Structural Frames for Factory & Workshop: They are used as the backbone for bolting down machinery, workbenches, mezzanine floors and security fences, providing a robust and versatile platform for manufacturing and automotive applications.
Solar Panel Mount and Industrial Equipment Supports: Strut channel is perfect for Solar panel arrays, industrial lighting and heavy machinery. With corrosion-resistant finish (hot-dip galvanized or powder coated) they can be used outdoors, by the sea, and in humid environments.
Load Requirements: Choose S355JR for heavier loads.
Environmental Conditions: Hot-dip galvanized channels for coastal or tropical areas.
Application Type: Cable trays, racking, or pipe supports.
Size & Thickness: Determine based on span and weight requirements.
Our engineers can help select the right Strut C Channel for your project, ensuring structural safety and cost efficiency.
