Double Jointed Strut Channels (also known as back-to-back welded strut channels) are heavy-duty structural components, manufactured by welding two standard strut channels together to form a rigid, high-strength section. Made of high-quality carbon steel, they are available with three surface treatments to suit different environments: pre-galvanized steel sheet, electro-galvanized finish and hot-dip galvanized finish. With standard sizes including 41×21mm, 41×41mm, 41×62mm and wall thickness from 1.5mm to 2.75mm, these channels offer significantly higher moment of inertia and allowable bending moment compared to single channels, making them ideal for heavy load applications.
Each specification comes with complete technical parameters including cross-sectional area, weight, yield strength, allowable stresses, moment of inertia and span load data. Widely applied in industrial piping, HVAC systems, seismic bracing and heavy-duty structural framing, they provide enhanced stability and load-bearing capacity for demanding construction projects.

Heavy-Duty Industrial Piping Systems: High-strength support framework for large-diameter, heavy industrial pipes, providing enhanced rigidity and load capacity.
Seismic Bracing Installations: Ideal for seismic bracing systems requiring high allowable bending moment and structural stability.
Overhead Heavy Load Supports: Designed for supporting heavy equipment and mechanical systems in industrial facilities.
Structural Framing for Demanding Environments: Suitable for outdoor, corrosive or high-load environments where single channels would be insufficient.
Select the suitable double jointed strut channel size, thickness and finish according to load requirements and environmental conditions.
Cut the channel to the required length using appropriate tools, ensuring clean and straight cuts.
Position the channel at the designated mounting location and mark the anchor points.
Secure the channel to the mounting surface using appropriate anchor bolts, ensuring it is level and stable.
Install accessories such as hangers, clamps and connectors onto the channel as needed, then place the supported pipes or equipment.
Inspect the entire assembly to confirm all connections are tight and the load is evenly distributed.
Conforms to general manufacturing standards for heavy-duty strut channel and structural framing components.
Galvanized finishes meet international anti-corrosion specifications for indoor, humid and outdoor use.
All products pass dimensional, material strength and surface treatment inspection before delivery.
Welded back-to-back structure provides significantly higher moment of inertia and allowable bending moment compared to single channels, suitable for heavy-duty applications.
Comprehensive range of sizes, thicknesses and galvanized finishes to match different load capacities and environmental needs.
Each specification comes with detailed engineering parameters and span load data, allowing accurate structural design and safe selection.
Compatible with all standard strut channel accessories, hangers and clamps, offering full system integration.
High-quality carbon steel combined with galvanized finishes ensures long service life in most environments.
Welded construction eliminates movement between channels, providing superior rigidity and structural integrity.
