Non-standard U-shaped channel steel welded support / equipment load-bearing bracket

Structural and Process Details

1. Main Structure

• Channel Body: Hot-rolled channel steel is cut into a U-shaped groove structure, providing strong resistance to bending and deformation. It can directly clamp pipes, square tubes, and equipment feet, ensuring stable positioning and preventing slippage.

• Connecting Ear Plates: Both ends are vertically welded with bent connecting plates. Each plate has pre-drilled bolt holes, allowing for rigid locking to the ground, frame, or wall using expansion bolts/Hexagonal socket head cap bolts.

• Welding Process: Full, continuous fillet welds are used. After welding, slag, spatter, and sharp burrs are removed by grinding. The welds are full and uniform, eliminating incomplete welds and slag inclusions, ensuring reliable structural load-bearing strength.

2. Materials and Surface Treatment

• Commonly Used Base Materials: Q235B carbon structural steel is commonly used. For heavy-duty applications, Q355 low-alloy high-strength steel can be upgraded. For high corrosion resistance requirements, 304 stainless steel can be used as an alternative. Plate thickness and channel steel specifications can be customized as needed.

• Anti-corrosion coating: Overall sandblasting for rust removal → electrostatic powder coating (epoxy resin powder). The coating has strong adhesion, is impact-resistant, moisture-proof, and rust-proof, suitable for long-term use in indoor cleanrooms and mild outdoor environments; it can also replace hot-dip galvanizing, paint spraying, passivation, and other surface treatments.

Core Product Advantages

1. Excellent Load-Bearing Capacity: The U-shaped cross-section of the channel steel boasts excellent mechanical properties, resisting bending and compression, making it suitable for concentrated load support in small and medium-sized equipment, modules, and pipelines, and resistant to deformation and breakage.

2. Convenient and Flexible Installation: The double-ear plates have standard bolt holes, allowing for direct drilling and locking on-site. The channel body can be embedded into the workpiece for positioning and limiting, resulting in high installation efficiency.

3. Fully Customizable (Non-Standard): Length, channel width, plate thickness, ear plate height, hole diameter, number of openings, and surface color can all be customized to match equipment drawings.

4. Durable and Easy to Maintain: The powder-coated surface is waterproof and rust-proof, resistant to paint peeling and rust, with a clean and aesthetically pleasing appearance, suitable for automated equipment, cleanrooms, and assembly line frame appearance requirements.

5. Controllable Welding Quality: Strict control over welding deformation, post-weld correction and shaping, ensuring flatness and perpendicularity tolerances meet standards, and maintaining stable consistency in batch production. 

Main Application Scenarios
