Q345GJE Q345GJD Material H Beam
Q345GJE Q345GJD Steel Beam H
Q345GJE belongs to the construction of structural steel, referred to as high-construction steel, grade meaning: Q is the yield initials, 345 is the yield value, the unit MPa, GJ is the high-construction initials, E indicates that the quality of steel is divided into grade E, -40 ° C impact.
Q345GJE h type beam is widely used in high-rise buildings, ultra-high-rise buildings, large-span stadiums, airports, exhibition letter, steel structure plant and other large-scale construction projects because of its easy welding, low-temperature impact resistance, seismic, stable performance and other performance characteristics.
Q345GJD is an important material with high strength, toughness and wear resistance.
Q345GJD h type steel beam has good plasticity and toughness, with high yield strength and tensile strength. At the same time, the material also has good wear resistance and impact resistance, and can withstand higher loads and pressures. It can still maintain high strength and toughness at low temperatures and is suitable for use in cold environments.
Q345GJD h profile steel is widely used in the manufacture of construction machinery, steel structures, bridges, ships, mining equipment, petrochemical equipment and other fields. Due to its good mechanical properties and welding performance, it can withstand the demand of high strength and high load under complex working conditions, so it is widely used in heavy machinery manufacturing and steel structure engineering.
