What is I300 Steel? Latest detailed price list

Overview of I300 Steel

I300 Steel, also known shortly as I300, is a type of carbon steel with a cross-section resembling the uppercase letter “I,” with two short flanges narrower than the connecting part in the middle.

This steel product has the ability to withstand large loads and forces, with high balance and robust impact resistance. When coated with a zinc layer on the surface, I300 Steel has higher strength, suitable for outdoor construction projects, especially in areas with harsh weather conditions, high humidity, large temperature variations, or acidic environments.

Applications of I300 Steel

I300 Steel, a medium-sized I-shaped steel, plays an important role and has various applications in different areas of life.

In the construction and civil engineering industry, I300 Steel is often used to build beams, columns, girders, and foundations for factories, high-rise buildings, prefabricated houses, bridge structures, and other construction projects.

In the field of mechanics and manufacturing, this steel is commonly used to produce crane bridges, steel antenna components, electric transmission towers, truck frames, and various applications in the industrial sector.

In the shipbuilding industry, I300 Steel is often applied to construct ship hulls, ship frames, drilling rigs, and other important structures in the production and assembly of ships.

Classification of I300 Steel

Currently, I300 Steel is classified into three main types as follows:

Cast I300 Steel

Produced using advanced casting processes that meet international standards. Cast I300 Steel has high hardness, strength, and good load-bearing capacity. This product has a reasonable cost and is widely used. However, prolonged exposure to acidic or salty environments can lead to oxidation, corrosion, and rust.

Galvanized I300 Steel

This is cast I300 Steel coated with an external layer of zinc to protect the steel layer inside. This zinc layer minimizes the oxidation process, protecting the steel from the adverse effects of the environment. In addition, the zinc layer enhances aesthetics and surface hardness. The price of galvanized I300 Steel is usually higher than cast steel of the same type.

Hot-dip Galvanized I300 Steel:

This type of I-shaped steel is cast after the surface is dipped into a hot-melt zinc coating furnace. The zinc layer forms a multi-layer alloy film with high adhesion, providing excellent corrosion and oxidation resistance. I300 Steel has a bright surface, increased aesthetics and lifespan, and usually has the highest price among the three types of steel.
