Heavy-Duty HDG Square U-Bolts for Structural Tubing and Solar Frames

HDG square U-bolts with precise 90° radiused corners fit square/rectangular steel tubes perfectly without point pressure. Controlled bending prevents zinc coating peeling; matched overtapped nuts avoid thread jamming. Thick hot-dip zinc offers long anti-corrosion performance for solar brackets, boat trailers and agricultural frames. Custom sizes and supporting cross plates available, moisture-proof export packaging for sea shipment.
