4 Types of Structural Steel

Understanding Structural Steel

Structural steel is one of the most versatile materials used in construction. It is strong and durable, making it perfect for creating a wide range of structures. In this blog post, we’ll take a look at some of the main forms of structural steel and how they can be used to shape different types of structures.

H-Beams  –

H-beams are commonly used in residential construction due to their low cost and ease of installation. This type of steel beam consists of two horizontal flanges that are connected by a vertical web. This makes them ideal for creating walls, floors, and roofs since their shape allows for easy attachment to other components. Additionally, H beams can also be used for supporting large spans such as bridges or overpasses.

Angle Iron –

Angle iron is composed of two flat plates that are connected at an angle to form an ‘L’ shape. This type of structural steel is often used in the construction of frames as well as support beams for walls and floors. Angle iron is relatively inexpensive and easy to install, making it a popular choice amongst builders who need to construct strong yet economical structures quickly.

I-Beam –

I-beams are characterized by their distinct “I” shape, which makes them incredibly strong while still maintaining a lightweight profile. This makes them perfect for use in construction projects where space is limited but strength is required, such as bridge supports or roof trusses. I-beams are also often used in commercial buildings due to their ability to span large distances with minimal use of material.

Plate Steel –

Plate steel is a flat sheet metal that is usually cut into smaller pieces before being bent and formed into various shapes. Plate steel has many uses, including forming columns, beams, and braces, as well as providing reinforcement in concrete foundations or walls. Plate steel can also be combined with other materials, such as wood or aluminum, to create custom structural components for specific purposes.


Structural Steel plays an important role in modern-day construction projects due to its versatility and strength when compared with other building materials such as wood or concrete. In this article, we took a look at four common forms of structural steel – H-beams, angle iron, I-beam, and plate steel – which are all widely used by builders around the world when constructing strong yet economical structures quickly. With the right knowledge and skillset, you, too, can use these materials effectively when constructing your own buildings or structures!
