What is a Steel Structure?
A Steel Structure is a building system where steel is the primary load-bearing material. It enables rapid construction through prefabrication and on-site assembly. These prefab steel structures typically use high-strength steel, like hot-rolled or cold-formed sections, which offer excellent tensile strength and durability. This allows them to withstand natural disasters such as strong winds and earthquakes.
Their modular design is one of their main advantages. Construction time is greatly reduced since parts are prefabricated in factories and then delivered to the construction site for assembly. In addition to commercial and industrial structures, this technique is increasingly being applied in public and residential spaces.

Types of Steel Structure Buildings
Portal Frame Steel Structure
A portal frame steel structure is a traditional structural system. It consists of inclined rafters, columns, bracings, purlins, and tie bars. Its mechanical principle relies on a transverse rigid frame made of beams and columns. This frame resists wind and gravity loads through bending, with a clear load transfer path.
These steel structure buildings often use tapered H-shaped steel sections to optimize material use and reduce weight. They are known for being lightweight, fast to construct, and efficient. The building envelope is often constructed of corrugated metal sheets or color-coated steel sheets, combined with cold-formed thin-walled steel purlins, creating an energy-efficient and environmentally friendly building system.
Gabled frames are widely used in industrial plants, warehouses, gymnasiums, and supermarkets – buildings that require large spans.
Frame Structure
This is one of the most common steel structure types. It forms a stable load-bearing system through rigid connections between beams and columns. It is widely used in high-rise buildings, industrial plants, and commercial centers because it allows for large, flexible spaces.
Frame structures also offer good seismic performance. Steel’s high modulus of elasticity helps absorb earthquake energy, reducing structural damage. In practice, they are often combined with materials like concrete or glass to enhance aesthetics and functionality.
In summary, frame structures are an economical and practical choice, especially for projects requiring fast delivery and flexible design.
Space Frame Steel Structure
This is a three-dimensional grid system, typically used for long-span buildings like stadiums, exhibition halls, and airport terminals. It forms a stable spatial system through members and nodes, covering large areas without intermediate support columns.
The advantage lies in its light weight and high strength. It uses relatively less steel but can carry heavy loads. This structural type also offers great design freedom, enabling unique architectural shapes and visual impact.
Construction requires precise calculation and assembly, often relying on specialized software and teamwork. With advancing technology, space frames play a key role in sustainable building by reducing material waste and extending service life.
Overall, space frame structures are an ideal solution for long-span needs, showcasing modern engineering innovation.

In addition, we also have rich experience in packing. We will plan the packing location of the parts and the maximum use space, as far as possible to reduce the number of packing for you, and reduce the cost of shipping.
You may be worried about the problem of unloading. We put an oil wire rope on each package of goods to ensure that after the customer receives the goods, they can directly pull the whole package of goods out of the box by pulling the oil wire rope, saving time, convenience and manpower!
Steel structure construction
The components are transported to the construction site for foundation preparation and foundation construction, a critical step in steel structure construction, as a solid foundation ensures the stability of the entire structure. During the on-site assembly phase, the client uses equipment such as cranes to lift the steel structure components into place and connect them via bolts or welding.
Acceptance of Steel Structures
After installation, the structure’s axis, elevation, and verticality must be thoroughly re-measured. Any deviations exceeding the standard must be fine-tuned using tools such as jacks and guy ropes. After each unit is completed, a supervisory inspection will be conducted to check component position deviations, bolt tightening, weld quality, and structural stability. Only after passing these inspections can the next step be initiated.
Safety management is implemented throughout the entire installation process. During lifting, a dedicated person is assigned to direct the work. The load capacity of the lifting equipment is checked before lifting, and a safety factor of 6 or greater is required. Workers working at heights must wear safety belts, and a temporary operating platform must be established on the work surface. Site scrap materials are cleaned daily to avoid safety hazards. In the event of severe weather such as strong winds (≥10.8 m/s) or heavy rain, lifting operations must be stopped immediately and installed components must be secured. A series of measures are implemented to ensure safe and orderly construction and high-quality completion of the steel structure installation project.
The advantage of steel structure construction lies in its modular nature, which can significantly shorten construction time and reduce on-site operational risks.
