U-shaped Square Box for 3D Welding Table, High Quality

• Material: Q355B/HT300
• Main Applications: Connection of system components. Uses connecting bolts to connect 3D workbenches or extend the sides of workbenches.
• If the length is ≥ 500mm, the U-shaped box has connection holes on the back for mounting support legs to match platform support legs.
• 5 working surfaces, all system holes with protective countersunk holes, perfect design and ultimate functionality.
• The U-shaped box is reinforced with additional stiffening plates.

• Height Support (Elevating Workpiece): Vertical placement provides a stable vertical reference for welding tall workpieces/frames.
• Table Expansion (Extending the Worktable): Side mounting locks to the side of the platform, extending the table horizontally/vertically to accommodate large workpieces.
• 90° Vertical Reference (Right-Angle Positioning): Multi-faceted high-precision planarity/perpendicularity (±0.1mm/m), serving as a right-angle template.
• Clamping and Mounting Base: U-shaped grooves allow direct clamping of workpieces; surfaces can be fitted with fixtures/positioning blocks.
• Spatial Assembly: Multi-piece assembly constructs a three-dimensional frame, multi-level workstations, and gantry-style tooling.

• Vertical support: Base locking platform → Vertical support
• Side expansion: Side locking platform → Widening/Lengthening
• Assembly assembly: Multiple U-shaped components + angle iron + connecting plate → 3D fixture
• U-channel clamping: Workpiece placed in U-channel → Quick clamping
