Round U Bolt By Feature
Our U-bolts have a variety of different features for you to choose from. In addition to material choices, they also include differences in surface treatment, shape design, and leg length. For example, the surface treatment includes hot-dip galvanizing and black oxidation treatment. Options, hot-dip galvanizing can significantly improve corrosion resistance and is suitable for outdoor or humid environments;
Black oxidation treatment has a certain anti-rust ability and aesthetics. In terms of shape design, semicircular and flat bolts are common, and semicircular U-shaped bolts are the most common, which can provide good bearing capacity and stability;
The flat U-bolt has a straight bottom, and a larger contact area with the connector, and can disperse the pressure. It is suitable for occasions that bear greater pressure or require extremely high connection stability.
The extended leg U-bolt is aimed at special application scenarios, such as thicker plates, large pipes, etc., providing longer threaded rods and wider openings to adapt to larger installation space and higher stress requirements. These diverse features enable U-bolts to be widely used in various industrial fields and different scenarios in daily life.
