Structural Frame
A structural frame is the backbone of a building or structure, providing support and stability. It's essentially a skeletal system that distributes weight evenly throughout the structure, preventing stress concentration and potential failure points. Common materials used for structural frames include steel, concrete, wood, and masonry.

Features of Structural Frame
High strength and light weight
Steel has higher strength and lower density. Compared with traditional concrete structures, the dead weight of steel structural frames is lighter under the same load. This not only reduces the bearing pressure of the foundation, reduces the cost and construction difficulty of the foundation project, but also facilitates transportation and installation. For example, in some large petrochemical projects, the use of steel structural frames can greatly reduce the weight of the entire device, which is particularly important for projects built on soft soil foundations.
Good toughness and ductility
Steel has good toughness and ductility, and can absorb and dissipate a large amount of energy under natural disasters such as earthquakes and wind disasters or other accidental loads to avoid sudden brittle failure of the structure. In petrochemical production, some sudden dynamic loads may be faced, such as vibration caused by equipment failure, explosive impact, etc. This performance of the steel structure frame can ensure that the structure can still maintain a certain carrying capacity and stability under these circumstances., improving the safety of the entire production device.
Good fatigue resistance
Petrochemical production usually operates continuously, and steel structural frames will withstand repeated loads for a long time. Steel has good fatigue resistance. Reasonably designed and manufactured steel structural frames can maintain good performance under long-term repeated loads, reduce the risk of structural fatigue damage, and extend the service life of the structure.
Fast construction speed
Steel structural members are standardized in the factory and then transported to the construction site for assembly, reducing on-site wet operations and complex construction processes. Compared with concrete structures, steel structural frames are installed faster, which can greatly shorten the construction period of the project, enable petrochemical units to be put into production faster and improve investment efficiency. For example, for some petrochemical projects using prefabricated steel structures, the installation of the main structure can be completed in a few months, while concrete structure projects of the same size may take longer.
To help you quickly calculate the cost of steel structures, please prepare the following information in advance
1. Dimension: Length, width, height, eave height, roof pitch, etc.
2. Doors and windows: Dimension, quantity, position.
3. Local climate: Wind speed, snow load, seismic magnitude etc.
4. Insulation material: Panel type, sandwich materials, sandwich thickness.
5. Crane metal structures: If have overhead crane, please tell the lifting height and lifting weight.
6. Is there any materials that are not allowed to import to the country where the structure is planning to use?
7. If you have other requirements, such as fire proofing, insulated roof, etc. Please let us know.
8. It's better if you have your own drawings or pictures. Please send them to us.
