2025 10 Leading steel structure Suppliers in the world

Dec 22, 2025Leave a message

Introduction to Steel Structure

Steel structure is a type of building structure composed of steel materials, which is one of the main building structure types. It is mainly made up of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. These components or parts are usually connected by welds, bolts or rivets. Steel structure has several remarkable advantages. Firstly, it has high strength and light weight, which allows for the construction of large - span and high - rise buildings. Secondly, it has good plasticity and toughness, enabling it to withstand large deformation without sudden fracture, thus providing better seismic performance. Thirdly, steel structure construction is highly industrialized, with short construction periods, which can significantly reduce the overall project time. Moreover, it is also environmentally friendly as steel can be recycled, reducing waste and resource consumption.
