Cable tray cantilever brackets are typically manufactured from high-strength steel, formed by stamping or welding, and surface-treated with hot-dip galvanizing or powder coating to ensure corrosion resistance. The design includes a vertical fixing plate, a horizontal cantilever beam, and cable tray mounting holes. It can be directly fixed to steel structures or concrete foundations with bolts.

Product Feature
High strength and good stability
Cable Tray Cantilever Support possess high mechanical strength, capable of withstanding significant loads and lateral tensile forces. They are widely used in large-scale key power engineering projects, effectively protecting cables.
Simple manufacturing and low cost
Cable Tray Cantilever Support are relatively simple to manufacture, using readily available materials at a low cost. They are suitable for general cable laying scenarios, such as cable tray support in ordinary buildings.
Flexible Design
The bracket features a multi-hole adjustment structure, allowing for flexible adjustment of vertical height and horizontal spacing, adapting to different cable tray specifications and complex on-site installation
Production Details
Material Preparation and Cutting:
Select appropriate angle steel materials based on pipe size and weight. Before cutting, ensure the steel is straight and use a toothed saw with an error not exceeding 5mm. The cut should be smooth and burr-free. Pipes with the same purpose or medium should share supports as much as possible to save materials.
Welding and Machining:
Assemble a template before welding to ensure accurate positioning of the columns and grids. During welding, perform spot welding first, then full welding to avoid deformation. Welds should be full, without weld beads or porosity. After welding, remove slag and grind burrs.
Drilling and Corrosion Protection:
Holes for supports must be machined; electric welding or gas welding is prohibited. Hole dimensions must match the pipe. Corrosion protection includes rust removal (exposing the metal color), applying anti-rust primer and topcoat. The total paint thickness should reach 0.1mm, with an 8-hour interval between each layer.
Installation and Fixing:
Before installation, lay out the positioning lines. Support spacing should be uniform and aesthetically pleasing. Securely fix with expansion bolts. For vertical pipes, vertical supports must be installed at bends, and direct welding should be avoided; protective plates must be added.
Quality Inspection:
Check whether the support material specifications match, whether the welds are full, whether the openings are standardized, whether the anti-corrosion layer is uniform, and whether the installation is secure.

FAQ
Q: How to Choose Cable tray cantilever supports?
A: The thickness of the galvanized layer on cable brackets directly affects their corrosion resistance and service life. According to common selection standards, the hot-dip galvanized layer thickness of cable brackets should be no less than 65μm. If the galvanized layer is insufficient, the bracket is prone to rusting, especially in outdoor or humid environments, which will significantly shorten its service life. For highly corrosive environments (such as chemical industrial areas and coastal areas), it is recommended to choose products with a thicker zinc layer; in some scenarios, the zinc layer can reach 30-50μm to enhance protection.
Q: Is the cantilever bracket easy to install and adjust?
A: The structural design includes adjustment space, allowing for fine-tuning of the position during installation for easy alignment and fixing.
Q: Are custom sizes available?
A: Custom manufacturing is available based on length, cross-sectional dimensions, and connection hole requirements.
