China Strut Channel Factory - Quality Suppliers 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 41ร21 mm (1-5/8" ร 13/16") for shallower applications and 41ร41 mm (1-5/8" ร 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.
