5 / 8 “ Diameter 316 Stainless Steel Bolts Standard Round Bend U Type OEM
1. Product Description
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends.
U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting.
u-bolts, also known as u-type card.
Pipeline installation commonly used as a bolt for fixing the pipe.
1, the material properties of density, flexural strength, impact toughness, compressive strength, elastic modulus, tensile strength, heat resistance, color is determined according to the use environment.
2, commonly used materials are carbon steel, galvanized steel, stainless steel. Wherein the stainless steel has 304,321,304L, 316,316l, 317,317L, 310S.
3, the national standard u-bolt: JB / ZQ4321-1997

3. Application
U-bolts are useful in different sizes for building up a antenna
construction;
- Mounting of round boom tubes to a mounting plate,
- Connection of signal or ground wires to tubes,
- Mounting of tubes at antenna rotators, etc.
4. Advantages
Key Benefit:
Easy to Install: the tilt-in module can be put into the extruded
rail from all kind of location, from residential and large
commercial, right throALEXh to utility scale and can be high
pre-assembly with the clamp to minimize the time and cost of
installation. The U bolt with the cap can fix the pipe easy and
quick.
Durability: the material of the components is Anodized
Aluminum6005-T5 & SUS 304, except for the nuts and hook is made
of stainless steel. Using galvanized tube fix with the ground,
material is Q235, surface treatment is hot-galvanized, the
thickness of the film more than 80um, which ensure products
quality. The connection between the rails is a reliable splice bar,
which makes the pole structure firmer, the wind resist can reach up
to 55m/s, 25 years product life cycle of structure and the warranty
is 10 years.
Good compatibility: Designed as a universal mounting system, our
mounting system is compatible with most of the major framed PV
modules on the market.
High quality: strict quality control cover the entire process from
material selection and manufacturing to pre-construction ensures
optimum life of our mounting system.
