Square U-Bolts -Galvanized Steel U-Bolts-Heavy Duty U Bolts

description

1.Rugged Performance – Cold-bent from high-strength carbon steel (typically ISO Grade 4.6 / SAE Grade 2) and hot-dip galvanized to ASTM F2329 for a zinc layer ≈ 55-75 µm thick. The coating delivers ≥ 600 h neutral-salt-spray resistance and self-heals small scratches, while the U-bolt retains ≥ 400 MPa tensile strength to clamp structural members securely in harsh outdoor settings.

2.Wide Application Range – Sized to cradle square or rectangular tubing, cable ladder, strut channel (41 × 41 mm), wooden joists, solar-panel frames, truck and trailer chassis rails, HVAC duct hangers, and farm implements—any installation that needs long-term corrosion protection plus a flush fit against flat surfaces.

3.Easy to Install – The square geometry nests neatly around flat profiles and inside channel slots; chamfered leg ends guide quickly through pre-punched holes. Supplied with matching galvanized hex nuts, flat washers, and (for larger sizes) clamping plates, so one mechanic and a single wrench can complete tightening from one side without special tools.

4.Assured Quality – Produced under ISO 9001 systems and checked per DIN 3570 Type B dimensions. Every batch is thread-gauge verified, proof-loaded to 1.5 × working load, and dip-coated after all cutting/rolling to guarantee full-coverage zinc. EN 10204 3.1 mill certificates and lot traceability are provided on request, ensuring consistent, dependable service life.
