Physical and Chemical Properties of Steel T Profile
Strength and stiffness: Steel T Profile provides high flexural strength and shear stiffness due to its unique cross-section shape. It can effectively resist external forces and vibration to ensure the stability and safety of the structure.
Weight ratio: This type of steel has a higher section modulus and lower weight than solid steel with the same load bearing capacity. This is conducive to reducing the structural weight and improving the material utilization rate.
Dimensional flexibility: Products of different heights, widths and web thicknesses can be customized according to specific requirements. This can meet the load bearing requirements under different working conditions.
Its chemical properties are mainly determined by its material. Common low carbon steel series such as Q235 and Q345, as well as stainless steel and weathering steel for special purposes. These steels have good weldability, corrosion resistance (for stainless steel and weathering steel) and machinability. The low carbon steel series is chemically stable at room temperature and is not easy to rust. However, it should be noted that in a humid and corrosive environment, workers should take protective measures.
Advantages and Disadvantages of Steel T Profile
Strong bearing capacity, suitable for long span, heavy load structure.
The structure design is flexible, and different specifications can be customized according to requirements.
Compared with solid steel, light weight, saving material costs.
Easy to install, compatible with welding, bolted connection and other ways.
Compared with some special-shaped steels, the degree of standardization of T-shaped steels may be lower. Therefore, if the customer wants some non-standard specifications of T-shaped steel, they need to find the factory to customize.
When used in extreme environments (such as high temperature, high humidity, strong corrosion), workers should pay special attention to protective measures to prevent the deterioration of steel properties.
