Q345GJ Q345GJZ H Metal Beam

 

 

Q345GJ h beam steel structure is used to manufacture high-rise building structures, large-span structures and other architecturally important structures. The size, shape, weight and permissible deviation of the steel should be in accordance with the provisions of GB/T 709, and the negative deviation of the thickness is limited to -0.3mm, and it can be made in the Z direction (Z12, Z25, Z35) if required, just like the Q345GJZ h shaped beam.

 

Q345GJZ h shaped iron beam is not only required to have certain mechanical properties along the width direction and length direction, but also required to have good ply tear resistance in the thickness direction.The ply tear resistance of Q345GJZ h type beam is evaluated by the sectional shrinkage of the thickness direction tensile test. Q345GJZ h type beam is a steel used for some important welded components such as high-rise buildings, shipbuilding, offshore oil platforms, boilers and pressure vessels.
