Scope of application
Product introduction: Hot-dip galvanized angle steel crossarm has also become a single-pole crossarm. The main raw material is equilateral angle steel. Its specifications are named according to the size of the angle steel and the length of the crossarm.
Single pole cross arm
Such as: ∠63×6×1800. It is used for the installation of single poles on transmission lines of 10kV and below. According to the installation, it is divided into single cross arm and double cross arm. Note: When ordering, the specification and model of the single-pole crossarm and whether to add support rod holes or provide drawings must be specified.

Name: High-strength bolts
Description: High-strength bolts are divided into torsion shear type high-strength bolts and large hexagonal high-strength bolts according to the construction process.
The torsion shear type high-strength bolt is composed of a bolt, a nut, and a washer. It is an improved type of large hexagonal high-strength bolts for the convenience of construction design.
High-strength bolts are mainly used in steel structure engineering. A very important ...
Bolts made of high-strength steel, or bolts that require a larger pre-tightening force, can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, steel rails, high-pressure and ultra-high-pressure equipment. The fracture of this kind of bolt is mostly brittle fracture. High-strength bolts applied to ultra-high pressure equipment need to be pre-stressed in order to ensure the sealing of the container.
