What is I-beam?

I-beam, also known as steel beam, is a long steel bar with an I-shaped cross section. Its unique cross-sectional design, including flanges and webs, gives it excellent strength and rigidity when subjected to bending and shear forces. This type of steel is widely used in many fields such as construction, bridges, and machinery manufacturing, and is an indispensable load-bearing component in engineering structures.

I-beam Classification

Ordinary I-beam: This is the most common type of I-beam, with standard cross-sectional shapes and sizes, suitable for a variety of conventional building structures, machinery manufacturing, and vehicle manufacturing.

Lightweight I-beam: Compared with ordinary I-beams, light I-beams have narrower flanges and thinner webs, so they are lighter and suitable for occasions with specific weight requirements, such as those that need to reduce the deadweight of the structure or facilitate transportation and installation.

Wide-flange I-beam: Its cross-sectional characteristics are that the two legs are parallel and there is no inclination on the inside, and the flange width is larger, providing better lateral support capacity. Wide-flange I-beams are usually used for large building structures that require higher load-bearing capacity and stability, such as high-rise buildings, large bridges, etc.

Advantages of I-beam

Design flexibility: The plasticity of I-beams makes cutting, bending and welding simple and easy, and its design flexibility also allows I-beams to be precisely adjusted according to actual needs.

Strong durability: I-beams have excellent aging resistance and long life. Their impact and wear resistance surpass many other materials, ensuring their stability and durability during use.

Light weight: I-beams are relatively light, and the construction process is simple and fast, which can save construction time and effectively improve the progress of the project.

Good physical properties: I-beams also have good insulation, magnetic permeability, and excellent fire retardant and insulation properties.

Low processing cost: The cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings.

Comprehensive coating protection: The galvanizing layer and the steel are metallurgically bonded, the coating is durable and reliable, and every part of the plated part can be galvanized, even in recesses, corners and hidden places.

Application of I-beam

Building structure: I-beams are often used as load-bearing components of building structures such as beams, columns, stairs, and platforms. Their high strength and compressive resistance make buildings more solid and durable.

Mechanical manufacturing: In the field of mechanical manufacturing, I-beams are widely used to manufacture supporting components, transmission shafts, brackets and other parts of various mechanical equipment. They have regular shapes, accurate sizes, and are easy to process and install.

Bridge construction: I-beams play an important role in bridge construction. They are often used in beam-type supporting components, bridge deck beams and other parts of bridges. Their high strength and rigidity can support the weight of bridges and vehicle loads.

Vehicle manufacturing: I-beams are also widely used in the manufacture of vehicles such as automobiles and trains. They are used in parts such as frames, suspension systems, and chassis structures to improve the safety and stability of vehicles.

Other fields: In addition, I-beams are also used for structural parts such as keels and bottom beams in shipbuilding, as well as equipment structure support in industrial fields such as petrochemicals and electric power.
