Application
Building field
- Structural frames: load-bearing structural frames, such as columns, beams and trusses, used in residential, commercial and industrial buildings. These hollow profiles have high strength-to-weight ratio and good resistance to bending and deformation, which can provide stable structural support.
- Tall buildings: Suitable for key load-bearing components in tall buildings due to its excellent structural integrity and load carrying capacity.
- Architectural features and decorations: Used for walkways, railings, sign structures and other architectural features, their light weight and easy installation make them ideal for enhancing the function and beauty of public Spaces and urban landscapes.
Engineering field
- Bridge construction: It is widely used in the beams, columns and support structures of Bridges, and can withstand large loads and complex stress conditions.
- Transport infrastructure: supporting structures and frame systems for transport facilities such as highways and railways.
- Industrial buildings and facilities: frame structures for industrial plants, warehouses, machinery and equipment, as well as material handling systems, storage racks, etc. Its high strength and durability enable it to meet the stringent requirements of industrial environments.
Other applicaitons
- Machinery and industrial equipment: frames for the manufacture of various mechanical components and industrial equipment, such as conveyor systems, processing lines, etc.
- Temporary structures and emergency response: Due to its rapid installation and disassembly characteristics, it is also commonly used in the construction of temporary structures and emergency response structures
Advantages
1. Structural performance advantagesHigh strength-to-weight ratio: These hollow profiles are able to significantly reduce the weight of the material while maintaining structural strength. For example, the C250 and C350 steel grades have minimum yield strengths of 250 MPa and 350 MPa respectively, which allows them to withstand large loads without adding too much weight.
Excellent torsional performance: Due to its closed cross-section shape, hollow profiles are superior in resistance to torsional forces. This characteristic allows it to provide better stability in structures subjected to complex load conditions, such as tall buildings and Bridges.
Good resistance to buckling: The closed section of the hollow profile allows for a more uniform distribution of stress, thus reducing the possibility of buckling under compressive loads. This allows longer unsupported spans to be used in structural design, increasing the flexibility of the building layout.
2. Economic and sustainability advantagesCost effective: Although the price per unit weight of hollow profiles may be slightly higher than that of solid profiles, their material usage is more efficient and material consumption is reduced. In addition, due to the light weight, the transportation cost is also low, and the processing and installation process is relatively simple, which can reduce labor costs and shorten the construction period, thus achieving cost savings of the overall project.
Sustainability: Steel is highly recyclable and hollow profiles can be effectively recycled and reused at the end of the structural life cycle. At the same time, its manufacturing process is relatively energy efficient, and when used in buildings, due to its corrosion resistance and long life, it can reduce maintenance needs and further reduce environmental impact, in line with the requirements of sustainable building practices.
3. Design and construction advantagesDesign flexibility: Hollow profiles have a variety of section shapes to choose from, such as round, rectangular and square, and designers can choose the most appropriate section shape according to the specific application needs. This diversity not only satisfies functional needs, but also creates aesthetically pleasing architectural structures.
Easy processing and installation: The processing of hollow profiles is relatively simple, including cutting, welding and joining operations. Its smooth surface and uniform cross section also make the installation process more efficient and can speed up construction.
4. Durability and maintenance advantagesCorrosion resistance: The closed cross section of the hollow profile reduces the exposed surface, thereby reducing the risk of corrosion. In addition, the corrosion resistance of the steel itself also makes the hollow profile have a long service life in harsh environments, reducing maintenance costs.
Long life: Due to its excellent structural properties and corrosion resistance, hollow profiles can maintain their performance for a long time, and have a long service life in construction and engineering structures, reducing the frequency of replacement and maintenance.
