Description
Looking for an electro-galvanized u-shaped wire to fix pipes or photovoltaic supports? This Q235 carbon steel U-bolt comes in market-standard and national-standard sizes. GoodsAxis sources it for businesses that buy fasteners in volume.

What an electro-galvanized u-shaped wire is
A U-bolt is a steel rod bent into a U shape, with threads on both ends. It wraps around a pipe, and nuts then clamp the pipe against a support. For example, a pipe of a given outside diameter needs a U-bolt sized to match it. Also, the data uses several names for this part, including U-bolt, curved screw and U-shaped fixing wire. Therefore, you may see any of those names in drawings and catalogues.
The data lists galvanized as the surface treatment, and the product name says zinc-plated. Electro-galvanizing deposits a thin zinc layer on steel with an electric current. As a result, the zinc helps protect the steel from rust. However, in general, a thin zinc coating protects less than a thick one in wet or outdoor sites. The data gives no coating thickness, so ask us to confirm that it fits your environment.
Next, the listed standard is JB/ZQ 4321-2006, with strength level 4.8 and product grade Class A. In addition, the applicable industries include construction, rail transit equipment, petrochemical and shipbuilding, and solar power generation.
