China Strut Channel Suppliers - Quality Factory Solutions for Electrical and Mechanical Support Systems
Product Overview
Strut channel, also known as slotted channel or mounting rail, is a standardized metal framing system widely used in construction and electrical industries for light structural support. It provides versatile solutions for supporting wiring, plumbing, HVAC, and mechanical components without the need for welding.
The most common sizes are 41×21 mm (1-5/8" × 13/16") for shallower applications and 41×41 mm (1-5/8" × 1-5/8") for higher load capacity. Wall thickness is customizable based on project requirements.
Material options include Mild Steel (MS), Pre-Galvanized (PG), Hot-Dip Galvanized (HDG), ZAM (zinc-aluminum-magnesium alloy), and Stainless Steel grades SS304 and SS316, allowing selection based on corrosion resistance needs and environmental conditions.

Features
Pre-punched holes along the base allow fast, flexible attachment to structures and interconnection between channels without drilling.
Inward-curving edges with serrations provide secure interlocking with channel nuts, preventing rotation under load.
Compatible with a full range of fittings, brackets, beam clamps, pipe clamps, and spring nuts for complete framing solutions.
Components can be assembled and adjusted using standard hand tools, with no welding required.
Suitable for light to medium structural loads including cable trays, conduit, piping, ductwork, and mechanical equipment.
Applications
Primary support for cable trays, conduit runs, electrical panels, and junction boxes in commercial and industrial buildings.
Supports water pipes, sprinkler systems, HVAC ducts, and refrigeration lines with adjustable pipe clamps and hangers.
Stable mounting for air handling units, ventilation ducts, fan coil units, and condenser units with flexible positioning options.
Widely adopted for rooftop and ground-mounted solar array frameworks, offering corrosion-resistant support structures.
Create equipment stands, machine bases, conveyor supports, and workstations with modular, reconfigurable components.
Used in exposed ceiling grids, lighting support systems, signage mounting, and decorative structural elements.
Support racks for antenna mounts, equipment shelters, and cable management systems in telecom infrastructure.
Employed in tunnel lighting, ventilation systems, and signal support structures for railways and roadways.
