Pre-Engineered Steel Buildings Clean Span Steel Frame Warehouse Workshop
Product Description
Steel structure is a metallic structure in which members composed of structural steel are connected to each other to carry a load and provide sufficient rigidity. Due to the high strength steel grade, this kind of structure is reliable and needs less raw material than other types of structures such as concrete and wood. The light steel structure material also allows for smaller foundations, reducing concrete quantity and saving costs.
In modern construction, steel structures are used in almost all types of buildings, including pre-engineered heavy industrial buildings, high-rises, and light steel structures. They are widely applied across various industrial areas such as workshops, warehouses, factories, and plants.
