What is I-beam steel?
I-beam steel is a type of steel with an I-shaped cross-section. It is also referred to as an I-beam or I-bar, commonly utilized in construction and industrial structures.

- Structure: I-beam steel has a wide belly and two narrow wings running along its length, creating an I-shape when viewed from a cross-section.
- Load-bearing capacity: This design helps I steel withstand bending, tensile, and compressive forces well and is suitable for heavy load applications.
- Application: I-beam steel is commonly used in bridge construction, factory buildings, steel frame structures, and many other industrial applications.
Common types of I-beam steels:
I-beam steel has many different sizes, suitable for each type of construction. Below are some common sizes:
- I100, I200, I300: Usually used for small and medium-sized projects such as houses, warehouses, and small factories.
- I400, I500: The top choice for large-scale projects involving factories, bridges, and steel structures.
- Larger sizes: Manufactured on request, meeting the needs of special projects.
Outstanding advantages of I-beam steels
- High load-bearing capacity: The wide wing and thick belly structure help I-beam steels withstand great pressure from many directions without deformation, ensuring stability and safety for the project.
- Lightweight: Compared to other types of steel such as H steel, I-shaped steel is lighter, helping to reduce the load on the construction, saving transportation and installation costs.
- I-beam steel is easy to cut, weld, bend, and shape according to design requirements, making it suitable for various applications.
- Many I-beams are either galvanized or painted to enhance their corrosion resistance, which extends their lifespan in harsh environmental conditions.
Applications of I-beam steels in construction
- I-beam steel is utilized in the construction of factories and warehouses as beams, columns, trusses, and mainframes due to its excellent load-bearing capacity and high durability.
- I-steel is an essential material in constructing bridges and roads due to its exceptional durability and strong load-bearing capacity, particularly for overpasses and suspension bridges that feature complex structures.
- Civil construction structure: I steel is widely used in the construction of high-rise buildings, apartments, and commercial centres, ensuring the solidity and safety of the project.
- Pre-engineered steel structures: I-beam steel is the main component in pre-engineered steel structures, helping to shorten construction time and increase design flexibility.
- Shipbuilding and machinery manufacturing: In addition to construction, I-steel is also used in shipbuilding, machinery manufacturing, and heavy industrial equipment.
