What Are the 4 Main Types of Steel Structures

With the growing demand for steel structure buildings, prefabricated steel structures and industrial steel construction worldwide, the developers and contractors as well as procurement managers are more and more required to know the types of steel structures. Whether at the infrastructure level or commercial and industrial construction, steel structures have long been the go-to solution for strength, stability, and the best-value for the long-term.

Below are the four main types of steel structures widely used in modern construction.

Frame Steel Structures

Frame steel structures are the most common form of structural steel construction, widely used in commercial buildings, industrial workshops, and high-rise steel buildings.They are made up of beams and columns of steel connected together by bolts or welding, which forms a rigid load-bearing frame.

With their design flexibility and excellent seismic performance, frame structures are most commonly used in areas where building regulations are stringent and the highest standards of safety are enforced.

Truss Steel Structures

The members of a truss steel structure are interconnected in a way that forms triangular units, which helps to evenly distribute loads.They are commonly applied in steel roof structures, bridges, stadiums, and long-span industrial buildings.

These structures have excellent strength to weight ratio with less consumption of steel, thus they are economical and are suitable for large span constructions.

Grid (Space Frame) Steel Structures

Grid steel structures (space frame structures) have a three-dimensional steel system and can bear loads from different directions. They are commonly employed in airport terminals, exhibition centers, transportation stations and large-scale public buildings.

With strong structural redundancy and modern architectural appeal, grid structures align well with the growing demand for large-scale steel construction projects.

Arch Steel Structures

The curved steel members of an arch truss efficiently carry loads to the foundation. They are commonly used in steel warehouses, hangars, logistics centers, and industrial steel sheds.

Because of simplicity design, quick construction and minimum maintenances, arch steel building become a trend in cost-sensitive and time-critical projects.
