American standard H-beam is an important metal structural material widely used in construction, bridges, ships, machinery manufacturing and other fields. It is favored for its excellent mechanical properties, high strength and corrosion resistance.
The shape of the American standard H-beam resembles the Chinese character "H", hence the name. It is a steel with an H-shaped cross-section with two cross-sections parallel and perpendicular to the bottom edge, which gives it better stability and stiffness when subjected to compression and tensile forces.
The main manufacturing standard for American Standard H-beams is the American Standard (ASTM), so they are also known as ASTM H-beams. This steel is hot-rolled or welded, which has high strength and good plasticity. Its tensile strength and yield point are higher than other types of steel, and it is able to withstand huge compression and tensile forces, so it is widely used in structures, such as buildings, bridges, etc., that need to withstand huge loads.
American standard H-beams also have good corrosion resistance and can be used in harsh environmental conditions. Its surface is treated with treatments such as shot peening or hot-dip galvanizing, which can further improve its corrosion resistance and service life.
American standard H-beams are widely used in bridges, high-rise buildings, factories and other building structures. In bridge construction, it can be used as the main support structure, bearing the weight of the bridge and the load of vehicles. In high-rise buildings, it can be used to support the floor structure and ensure the stability and safety of the building.
American standard H-beam is a very important metal structural material, which has the characteristics of excellent mechanical properties, high strength and corrosion resistance, and is widely used in various fields.
