C-section Steel Semi-welded Trailing Arm, High Strength Bracket Accessory, Solar/Cable Tray/Anti-seismic Support Fitting
Product Description:
Semi-welded Trailing Arm is a core accessory for C-section steel support systems, made of high-strength steel. Adopting a semi-welded structure, it balances firm connection and flexible assembly, widely used in solar bracket, cable tray, anti-seismic support, plant steel structure and pipeline support.
It is fully compatible with national standard C-section steel, with precise semi-welding at the connection to ensure high strength, anti-stretching, anti-vibration and no deformation. The compact structure disperses load effectively, enhancing wind and snow resistance. Easy to install, adjustable in position and angle, with galvanized/painted anti-corrosion treatment, it features long service life and high cost-performance, suitable for industrial construction, municipal engineering and new energy power stations.

Installation and Usage Notes:
- Before installation, check whether the semi-welded trailing arm is intact, ensure there is no damage, crack or rust on the welding joint and body, and confirm that the specification matches the C-section steel to be installed.
- During installation, use professional tools to connect the trailing arm with C-section steel, ensure the connection is firm, and the welding joint is free from looseness. Do not overload or forcibly assemble to avoid structural damage.
- The installation position should be aligned with the stress point of the support system, and the angle should be adjusted according to the on-site working conditions to ensure uniform load bearing and avoid local stress concentration.
- After installation, conduct a comprehensive inspection, test the bearing capacity and stability, and put it into use only after confirming that it meets the safety requirements.
- During use, regularly check the welding joint and connection part, and timely maintain or replace if rust, looseness or deformation is found.
- It is strictly prohibited to use the product beyond the specified bearing capacity and applicable temperature range to avoid safety accidents.
- During transportation and storage, avoid collision and extrusion, and place it in a dry and ventilated environment to prevent corrosion.
