Low-alloy I-beams Q355B and Q345B are two common types of I-beams that have some unique characteristics.
Q355B I-beam is a low-carbon alloy I-beam, which has good comprehensive mechanical properties and corrosion resistance. This type of I-beam has high strength and stiffness, and is able to withstand large pressures and bending moments. At the same time, it also has good welding performance and is easy to process and connect.
Q345B I-beam is also a low-alloy I-beam, which is similar to Q355B I-beam but has higher strength and better toughness. This kind of I-beam can maintain good stability and durability when subjected to large pressure and bending torque. In addition, it has good fatigue resistance and is able to withstand repeated loads.
Both types of I-beams are widely used in construction, bridges, ships, vehicles, and other fields. For example, in bridge construction, they can be used as main beams or beams to withstand large loads;In shipbuilding, they can be used as the main material for the structure of the hull;In vehicle manufacturing, they can be used as the main material for structures such as frames, chassis, etc.
